A plain /model <name> switch only lasted for the current session — every
new session reverted to the previously-configured model, so users had to
re-switch every time (e.g. glm-5.1 -> glm-5.2 on every launch).
Persist-by-default is now the behavior across all three /model surfaces
(CLI, gateway, TUI/dashboard), gated by a new config key
model.persist_switch_by_default (default true):
/model <name> switch model (persists to config.yaml)
/model <name> --session switch for this session only
/model <name> --global switch and persist (explicit, unchanged)
The effective persistence is resolved once via resolve_persist_behavior()
in hermes_cli/model_switch.py so --session opts out, --global opts in,
and the config-gated default applies otherwise. --global remains a valid
explicit no-op alias for the new default.
Commit 6724daa2c added refresh_interval=1.0 to keep the idle clock
ticking, but unconditional 1 Hz redraws in non-fullscreen prompt_toolkit
mode cause terminal emulators (Xshell, iTerm2, Windows Terminal) to
auto-scroll to the bottom on every tick — breaking scroll-up to read
history.
Drive it from display.cli_refresh_interval (0 = disabled, the default)
so users who want the ticking clock can opt in without affecting everyone.

git worktree lock at creation and unlock before removal. A locked
worktree refuses 'git worktree remove' (and prune), so a second hermes
process or a stray cleanup can't silently delete an in-use isolated
worktree. Fail-soft on both paths — a lock/unlock error never blocks
the session or cleanup.
Salvaged from #47029 (Issue #46303). Unlock moved to the actual-removal
path so a preserved (unpushed-commits) worktree stays locked while in use.
When SessionDB init fails, the CLI/Desktop previously continued live with only
a buried log line. The chat looks healthy, but the transcript is never written
to state.db — so resume later shows a truncated or empty session and the user
only discovers the loss after the fact (#41386).
Emit a prominent stderr banner at startup when the store is unavailable, making
it explicit that the conversation will not be saved and cannot be resumed, with
a pointer to fix the store. Also set _session_db_unavailable so downstream code
can detect the degraded state.
The interactive model pickers (Desktop REST API, TUI model.options, CLI
/model) were hard-capped at max_models=50, which truncated large provider
catalogs like Kilo Gateway (336 models) to just 50 entries. This made
most models undiscoverable via the picker search box.
Changes:
- Change build_models_payload() default from max_models=50 to None (unlimited)
- Change list_authenticated_providers() default from max_models=8 to None
- Change list_picker_providers() default from max_models=8 to None
- Fix all [:max_models] slicing to handle None as 'no limit'
- Remove max_models=50 from 5 interactive picker callers:
* web_server.py: get_model_options (Desktop /api/model/options)
* web_server.py: get_recommended_default_model
* model_switch.py: prewarm_picker_cache_async
* tui_gateway/server.py: model.options JSON-RPC
* cli.py: HermesCLI model picker
- Telegram/Discord inline keyboard picker (gateway/slash_commands.py)
still passes max_models=50 explicitly — unchanged behavior.
The total_models field was already in the response payload and is now
meaningful since models.length == total_models for interactive pickers.
Fixes#48279
compress_context() rotates the session (end_session -> create_session)
mid-turn when auto-compress triggers, but never called
_flush_messages_to_session_db() first. Messages generated during the
current turn that hadn't been persisted to state.db were silently lost.
The same bug existed in cli.py:new_session() (/new command). Both paths
now flush un-persisted messages before ending the old session.
* feat(billing): nous_billing http client + BillingState core (phase 2b)
Phase 2b terminal-billing client foundation:
- hermes_cli/nous_billing.py: typed client for the 4 /api/billing/* endpoints
(state/charge/poll/auto-top-up). Raises typed errors (BillingScopeRequired,
BillingRateLimited, BillingAuthError) mapped from the live-verified contract;
fail-open is the caller's job. Idempotency-Key enforced client-side.
- agent/billing_view.py: surface-agnostic BillingState core + Decimal money
parsing (server emits decimal strings, not 2dp), fail-open builder,
idempotency-key gen, custom-amount validation.
- 51 unit tests (decimal parse/format, payload tiering, error->exception
matrix, fail-open, amount validation).
Plan: docs/plans/2026-06-13-001-phase-2b-terminal-billing-tui-plan.md
* feat(billing): billing:manage scope + lazy step-up re-auth (phase 2b)
- NOUS_BILLING_MANAGE_SCOPE constant.
- nous_token_has_billing_scope(): split-based scope check (no false-positive
substring match).
- step_up_nous_billing_scope(): re-runs the device flow requesting
billing:manage, reusing the held credential's portal/inference URLs + client_id
(so a preview stays a preview), persists like _login_nous but WITHOUT the model
picker. Returns True iff the minted token carries the scope (False when NAS
silently downscopes a non-admin / unticked grant).
Lazy step-up (plan D-A): normal login path unchanged; 403 insufficient_scope
from a billing call triggers this. 7 unit tests.
* feat(billing): billing JSON-RPC methods for the TUI (phase 2b)
billing.state / charge / charge_status / auto_reload / step_up in
tui_gateway/server.py. Return STRUCTURED success envelopes (result.ok +
result.error=<code>) rather than JSON-RPC-level errors, so the Ink rpc() promise
always resolves and the TUI branches on the typed billing error code
(insufficient_scope, rate_limited, no_payment_method, …) to render the right
affordance. Money serialized as decimal STRINGS + display strings. charge mints
+ echoes an idempotency_key for retry reuse. 16 unit tests.
* feat(billing): /billing CLI handler + command registry (phase 2b)
- CommandDef("billing", subcommands=buy|auto-reload|limit), added to
_SLACK_VIA_HERMES_ONLY so it routes via /hermes on Slack (keeps the 50-cap
parity test green, same as /credits).
- cli.py::_show_billing + screen helpers: all 5 screens (overview, buy→confirm→
poll, auto-reload, monthly-limit read-only). Reuses _prompt_text_input_modal /
_prompt_text_input (D-C). Non-interactive (_app is None) renders text + portal
deep-link, never prompts (R7). Decimal money end-to-end. 2s/5-min cancellable
poll loop; 429/503 = retry not failure; settled = ledger truth. Lazy step-up on
403 insufficient_scope. no_payment_method treated as mainline funnel-to-portal.
- 6 CLI tests; 156 command tests (incl. Slack/Telegram parity) green.
* feat(billing): /billing Ink TUI screens + tests (phase 2b)
- ui-tui/src/app/slash/commands/billing.ts: /billing TUI command covering all 5
screens — overview (text), buy <amt> → ConfirmReq → charge → non-blocking 2s/
5-min poll loop → settled/failed/timeout branches, auto-reload <below> <to> →
ConfirmReq → PATCH, limit (read-only). Reuses the existing ConfirmReq overlay
(D-C) — no bespoke component. Typed-error envelope branching: insufficient_scope
arms the lazy step-up confirm; no_payment_method/rate_limited/cap funnel to
portal. Client-side amount validation mirrors the server (bounds + 2dp).
- gatewayTypes.ts: Billing* response interfaces.
- registry.ts: register billingCommands.
- billingCommand.test.ts: 12 vitest cases (overview/gating/buy-confirm-poll-
settled/no_payment_method/step-up/limit/auto-reload/validation).
TUI build green; 12/12 vitest pass; slash tests pass once @hermes/ink is built.
* docs(billing): scrub private cross-repo references
NAS is a private repo — remove all references to it from the public PR:
- drop the cross-repo planning doc (planning scaffolding, not a deliverable;
the PR description documents the design)
- replace 'NAS' / 'PR #412 preview' mentions in code + test comments with
generic 'the server' / 'a preview deployment'
* docs(billing): scrub final NAS reference in step-up docstring
* docs(billing): drop dangling plan-doc refs
The phase-2b plan doc was removed in the cross-repo scrub (300afcc0b)
but two module docstrings still pointed at it. Drop the dead refs.
* feat(billing): interactive /billing overlay + step-up UX, portal-URL & token fixes
Adds the interactive /billing TUI overlay and hardens the terminal-billing
client across CLI and TUI.
- TUI: full /billing overlay state machine (overview to buy to confirm,
auto-reload, read-only monthly limit) reusing the existing confirm overlay.
- Step-up: surface the verification link in-transcript and open the browser
via the TUI's own opener (the device flow runs in the headless gateway, so a
printed URL was being dropped); run the step-up handler off the main loop and
emit the link as an out-of-band event so the gateway stays responsive.
- Step-up copy is scope-accurate ("Billing permission granted") and re-checks
/state so it never claims "enabled" when the org kill-switch is still off.
- Portal deep-links resolve to absolute URLs against the active portal base
(the server emits them relative) - fixes a bare "/billing?topup=open" link.
- Billing calls refresh an expired access token via the stored refresh token
instead of reporting a false "not logged in".
- Optimistic funnel: advise "set up a saved card on the portal" up front when
no card is on file (advisory, not a hard gate).
- Token resolution is cached briefly so the 2s charge poll loop stops
re-locking + re-reading the auth store on every tick; 401 re-resolves fresh.
- Remove the temporary demo-mode shims.
Validation: 87 Python billing tests, 88 TS tests (billing command + gateway
event handler), tsc clean, ink + ui-tui builds green.
* docs(billing): add /billing TUI screenshots for PR
* fix(cli): guard _last_invalidate on bare instances; update stale prompt-fallback test
The UI-invalidate throttle read self._last_invalidate unconditionally, which
raised AttributeError on HermesCLI instances built without __init__ (the
thread-safety test's object.__new__ shell). Guard the read with getattr.
The off-main-thread branch of _prompt_text_input was changed (#23185) to cancel
cleanly to None instead of falling back to a bare input() that would hang on the
slash-worker thread; the test still asserted the old direct-input fallback.
Update it to assert the current intended behavior: returns None, calls neither
run_in_terminal nor input(), and does not hang.
The interactive CLI input box runs its completer with
`complete_while_typing=True`, so `SlashCommandCompleter.get_completions`
is invoked on *every* keystroke. That completer does blocking I/O:
fuzzy `@`-file indexing shells out to `rg`/`fd` (up to a 2s timeout) and
file-path completion calls `os.listdir` + `stat`. Because the completer
was passed inline (never wrapped in `ThreadedCompleter`), all of this ran
synchronously on the prompt_toolkit event loop, stalling the render after
each key — very noticeable on WSL2 and other slow-filesystem setups
("typing in the prompt box being very latent").
Two fixes:
- Wrap the input completer in `ThreadedCompleter` so completion work runs
off the UI event loop and never blocks rendering between keystrokes.
- Stop treating URLs as file paths in `_extract_path_word`: a token like
`https://example.com/x` contains `/`, so it triggered `os.listdir` on
every keystroke while typing/pasting a link (listing a bogus `https:`
dir) for a completion that can never be useful. Skip any token with a
`://` scheme separator.

* feat(delegation): async background subagents via delegate_task(background=true)
delegate_task(background=true) dispatches a subagent that runs in the
background and returns a handle immediately, so the user and model keep
working while it runs. The full result — plus the original task source —
re-enters the conversation as a new turn when the subagent finishes,
riding the same completion-queue rail as terminal background processes.
- tools/async_delegation.py: daemon-executor registry, capacity cap,
rich self-contained completion event pushed onto the shared
process_registry.completion_queue (type='async_delegation').
- delegate_tool.py: background param + single-task dispatch branch;
batch async rejected (v1).
- process_registry.py: format_process_notification renders the rich
task-source block (goal/context/toolsets/model/status/result).
- gateway/run.py: dedicated _async_delegation_watcher drains + injects
results into the originating session (idle + post-turn), session_key
routing enrichment, shutdown interrupt of dangling delegations.
- config: delegation.max_async_children (default 3).
Reuses the existing idle-drain wiring rather than mutating a running
agent loop, preserving message-role alternation and prompt-cache
invariants. 13 targeted tests; CLI + gateway paths E2E-verified.
* test(delegation): make async non-blocking tests environment-independent
CI 'test (5)' flaked on a cold, 8-worker runner: the first
delegate_task(background=true) call measured 2.27s of one-time setup
(config load + child-agent construction + imports), tripping the
elapsed < 1.0 wall-clock assertion. That assertion was testing setup
overhead, not blocking.
Replace the wall-clock thresholds with the real invariant: dispatch
returns while the child is still gated (active_count == 1, completion
queue empty), which a synchronous impl could not do. Keep only a loose
4s sanity backstop well under the runner's 5s gate.
* fix(delegation): harden async background delegation
Follow-up review fixes:
- Detach background child from parent._active_children at dispatch —
otherwise parent-turn interrupts (Ctrl+C, mid-turn steering), cache
evicts (release_clients), and session close (/new) kill/close the
detached subagent mid-run, defeating the point of background mode.
Lifecycle is owned by the async registry's interrupt_fn.
- Make the capacity check atomic with the record insert (TOCTOU: two
concurrent dispatches could both pass active_count() and exceed the cap).
- TUI dedup: key async_delegation events by delegation_id — the
fallthrough keyed them all as ("", type), suppressing every completion
after the first in the desktop/TUI status feed.
- CLI /stop now interrupts running background delegations and /agents
lists them (they live outside the process registry and were invisible).
- Drop stray unbalanced ']' line from the re-injection block and the
unused _ASYNC_DEFAULT import.
Tests: detach-at-dispatch + concurrent-capacity race added (15 total in
test_async_delegation.py); 137 delegate + 140 process-registry/notify/watch
+ 7 TUI dedup tests pass.
* fix(delegation): harden async background completion drains
* feat(billing): /usage → portal top-up browser handoff
Add the terminal side of the billing slice (phase 2a): start a top-up by
throwing the user to the portal billing page with the top-up modal open. The
terminal does not confirm, poll, or track payment — checkout completes in the
browser and the next /usage shows the new balance.
- nous_account.py: parse organisation.slug/name from /api/oauth/account into
NousPortalAccountInfo; add nous_portal_topup_url() building the org-pinned
{base}/orgs/{slug}/billing?topup=open with a null-slug fallback to the legacy
{base}/billing?topup=open (never /orgs/None/...).
- portal_cli.py: 'hermes portal topup' — fresh account fetch, identity line
(Topping up as <email> / org <name>), browser open with printed-URL fallback,
no-wait closing copy. No polling/confirmation (deferred to 2b).
- account_usage.py: the shared /usage credits block now links the org-pinned
top-up URL (auto-opens the modal) + points to the command.
Depends on NAS #409 (organisation.slug/name + ?topup=open). Do not merge until
that is live on the target env; until then /api/oauth/account returns
organisation: { id } only and the URL falls back to legacy.
* feat(billing): /credits command for balance + top-up handoff
Replace the standalone `hermes portal topup` subcommand with an in-session
/credits slash command — a focused money surface (balance in, top-up out) that
works in the CLI, TUI, and every messaging platform from one registry entry.
- commands.py: register /credits (Info category). Slack is at its 50-slash cap,
so /credits is routed via /hermes credits on Slack only (new
_SLACK_VIA_HERMES_ONLY set) to avoid clamping a canonical command off the
native list and breaking Telegram parity; native everywhere else.
- account_usage.py: build_credits_view() — one portal fetch → balance lines +
identity line + org-pinned top-up URL + depleted flag, consumed by all
surfaces. Reuses the same snapshot/URL builder as /usage so numbers match.
- cli.py: _show_credits() — balance block + identity line + 3-button panel
(Open top-up / Copy link / Cancel) via the existing prompt_toolkit modal.
ASK, never auto-launch; headless falls back to printing the URL.
- gateway/slash_commands.py: _handle_credits_command() — renders the block +
tappable top-up URL + no-wait copy; works on button and plain-text platforms.
- /usage credits line now points to /credits.
- Retire `hermes portal topup` (portal_cli.py back to baseline); the engine
(slug/name parse + nous_portal_topup_url) stays as the shared core.
No polling, no payment confirmation (billing phase 2a). Depends on NAS #409.
* fix(credits): /credits works in the TUI slash-worker (non-interactive)
In the TUI, /credits runs in the slash-worker subprocess where there is no
live prompt_toolkit app and stdin is the JSON-RPC pipe. _show_credits called
the 3-button modal unconditionally, which fell back to reading stdin →
exception → slash.exec rejected → the command produced no output (only the
pre-existing 'Credit access paused' banner showed).
- _show_credits: when self._app is None (TUI worker / piped / non-interactive),
render the text variant — balance block + tappable top-up URL + no-wait line,
same affordance as the messaging surfaces — and skip the modal entirely. The
3-button panel still renders in the interactive CLI.
- Depleted banner copy: 'run /usage for balance' → 'run /credits to top up'
now that /credits is the dedicated money surface (+ tests).
- Regression tests: _show_credits with self._app=None renders text and never
invokes the modal; logged-out path.
* feat(tui): credits.view RPC for the /credits tappable top-up button
Add a credits.view JSON-RPC method returning the structured CreditsView
(logged_in, balance_lines, identity_line, topup_url, depleted) so the TUI can
render a clickable <Link> top-up button instead of plain text. Account-
independent (portal fetch gated on a logged-in Nous account), fail-open to
{logged_in: false} on any hiccup. Mirrors session.usage's credits-block pattern.
Frontend (TUI-local /credits command + Ink component) lands separately.
* feat(tui): /credits command with keyboard-driven top-up confirm
TUI-local /credits: fetches the structured balance via the credits.view RPC,
prints the balance + identity + top-up URL, then arms the EXISTING confirm
overlay (Enter = open top-up in browser via openExternalUrl, Esc = cancel).
Reuses ConfirmReq — no new overlay component/state/input handler. Headless
(openExternalUrl returns false) falls back to printing the URL.
- gatewayTypes.ts: CreditsViewResponse.
- commands/credits.ts: the command (mirrors /status's rpc+guarded pattern).
- registry.ts: register creditsCommands.
- test: balance+overlay armed, headless fallback, no-url, logged-out (4 cases).
Matches the CLI /credits 'Enter to open' affordance. Phase 2a: no polling.
Modal prompt panels (dangerous-command approval, clarify questions)
live in the prompt_toolkit layout and vanish on the next repaint,
leaving no trace of the question or the decision in chat history.
Emit a dim one-line summary after each prompt resolves:
⚠ Approval: <command> → allowed for session
? Clarify: <question> → <answer>
Gated on display.persist_prompts (default true). Detail and outcome
are whitespace-collapsed and capped at 120 chars.
Reworks the chat-line UX: pick a recipe by name and the agent asks you for
what it needs, one question at a time, instead of forcing you to hand-type a
slot=val command line.
- /cron-recipe -> lists the catalog
- /cron-recipe <name> -> forgiving name match (exact/prefix/substring/
fuzzy; ambiguous lists candidates), then seeds
the agent with a natural-language fill request
built from the recipe's typed slots + schedule
and prompt templates. The agent asks for each
value one at a time and calls the EXISTING
cronjob tool. No new tool.
- /cron-recipe <name> slot=val -> unchanged deterministic path (fill_recipe ->
create_job) for the dashboard/docs/power user.
Mechanism (no new plumbing, invariant-safe — the seed enters as a normal user
turn, never a synthetic injection):
- shared handler returns RecipeCommandResult{text, agent_seed}; match_recipe()
and build_recipe_seed() are the new shared pieces.
- gateway: dispatch rewrites event.text to the seed and falls through to the
agent (the same pattern /steer uses).
- CLI: handler sets a one-shot self._pending_agent_seed; the interactive loop
consumes it right after process_command() and runs it as the next turn.
The typed-slot schema stays the single source of truth (still validates the
form/inline path via fill_recipe); the agent path just renders those slots into
the questions to ask. Docs updated to lead with the name-then-ask flow.
A 'recipe' is a one-place definition of an automation that every surface
renders natively. The slot schema (cron/recipe_catalog.py) is the single
source of truth; four renderers consume it, and all paths end at the same
cron.jobs.create_job — no second job engine.
Form where there's a screen, conversation where there's a chat line:
- Dashboard / GUI app: a Recipes sub-tab on the Cron page renders each
recipe's typed slots as a form (time-picker, enum dropdown, free-text);
submit POSTs /api/cron/recipes/instantiate which fills + creates the job.
- CLI / TUI / messengers: /cron-recipe lists the catalog, shows a recipe's
fields, or fills + creates from a pasted 'key slot=val' command. The shared
handler (hermes_cli/cron_recipe_cmd.py) names any missing/invalid slot so
the agent can ask a targeted follow-up.
- Docs: a generated Cron Recipes catalog page (website, .mdx + React cards)
shows each recipe with a copy-paste command and a 'Send to App' button.
- Desktop: a hermes:// URL scheme (Electron single-instance lock +
setAsDefaultProtocolClient + open-url/second-instance) routes
hermes://cron-recipe/<key>?slot=val into the chat composer pre-filled.
Typed slots (time/enum/text/weekdays) with defaults: users never type raw
cron — recipes parameterize time-of-day and weekday sets and translate to
cron expressions; a free-text 'schedule' slot is the full-flexibility escape
hatch. Consent-first throughout: nothing schedules without an explicit submit
or send.
Core:
- cron/recipe_catalog.py — CronRecipe + RecipeSlot, 5 curated recipes,
recipe_form_schema / recipe_slash_command / recipe_deeplink /
recipe_catalog_entry renderers, fill_recipe (validate + translate to
create_job kwargs).
- hermes_cli/cron_recipe_cmd.py — shared /cron-recipe handler (CLI + TUI +
gateway never drift). CommandDef + dispatch in commands.py / cli.py /
gateway/run.py.
Dashboard: GET /api/cron/recipes + POST /api/cron/recipes/instantiate
(web_server.py), CronRecipes.tsx gallery+form, Segmented sub-tab on CronPage,
api.ts methods + types.
Desktop: hermes:// scheme end to end (main.cjs deep-link router + ready-queue,
preload onDeepLink/signalDeepLinkReady, global.d.ts types, desktop-controller
composer prefill, electron-builder protocols key).
Docs: extract-cron-recipes.py generator wired into prebuild.mjs,
cron-recipes-catalog.mdx + CronRecipesCatalog React component, sidebar entry.
Generated index json gitignored like skills.json.
Tests: 23 core (catalog/slots/schedule-resolution/validation/renderers/command
handler/generator) + 5 web_server endpoint tests. E2E verified end to end:
slot fill -> create_job -> persisted job with correct schedule/deliver/origin.
Adds an idle clock to the context/status bar in both the prompt_toolkit CLI
and the Ink TUI: once a turn completes, a dim '✓ <elapsed>' segment shows how
long the session has been idle since the last final agent response. Hidden
while a turn is live (the per-prompt elapsed timer covers that) and before
the first turn completes.
- cli.py: track _last_turn_finished_at when the agent thread exits, surface
it via _format_idle_since() in the snapshot, render in both the wide
fragments path and the plain-text fallback.
- ui-tui: stamp lastTurnEndedAt when busy flips false after a live turn,
thread it through appStatus -> StatusRule, render via a ticking IdleSince
segment sharing the duration breakpoint/width budget.
User-defined quick_commands from config.yaml now appear in the /help
output under a "Quick Commands" section, between skill commands and tips.

* feat(agent): coding-context posture with per-model edit-format tuning
Hermes detects when it's running in a coding context — an interactive
surface (CLI, TUI, ACP, desktop) sitting in a code workspace (git repo or
recognised project root) — and shifts into a coding posture. Outside that
(chat platforms, non-workspaces) nothing changes.
The posture is modelled as a frozen RuntimeMode selected from a small
ContextProfile registry (coding/general). A profile is data: the toolset to
collapse to, the operating brief to inject, and seams for model routing and
memory. Every domain reads the same resolved object instead of re-probing
git/config on its own:
- System prompt — RuntimeMode.system_blocks(): an operating brief (gather
context before editing, edit through tools not chat, verify with terminal,
cap retry loops) plus a live git/workspace snapshot, built once and baked
into the stable prompt tier so per-conversation caching is preserved.
- Per-model edit-format tuning — the brief nudges each model family toward
the patch mode it handles best: OpenAI/Codex toward mode='patch' (V4A
multi-file diffs), Anthropic toward mode='replace' (string replacement).
The model id rides on RuntimeMode; unknown families keep neutral wording.
- Skill index — non-coding skill categories are pruned from the prompt's
skill index (discovery-only; skills_list/skill_view still reach the full
catalog, with a disclosure note).
- Toolset — only under the opt-in 'focus' mode does the posture collapse to
the coding toolset + enabled MCP servers; the default posture is
prompt-only and never overrides configured toolsets.
Activation via agent.coding_context: auto (default), focus, on, off.
Subagents inherit the posture for free via toolset inheritance + the shared
prompt builder. Detection is not memoized so a long-lived gateway/TUI
process can't pin a stale posture across working directories.
* feat(agent): cover new-file authoring in the coding edit-format nudge
The per-model edit-format guidance only addressed editing existing code
(patch mode='patch' vs 'replace'), but authoring a brand-new file —
write_file, not patch — is a large fraction of real coding work and the
nudge was silent on it. Surfaced when building a single-file artifact where
the dominant operation was write_file and the steering offered no guidance.
Both family lines now lead with "author new files with write_file; for
edits to existing code prefer ...". Tests assert write_file appears in each
family's brief; unknown families still get neutral wording.
* docs(agent): correct memoization docstring + clarify TUI config-load asymmetry
* feat(agent): sharpen the coding posture — verify-loop facts, wider edit steering, $HOME guard
Tuning pass on the coding posture from dogfooding it as a harness:
- Workspace snapshot now hands the model its verify loop up front:
detected manifests + package manager (lockfile sniff), the exact
verify commands (package.json scripts, Makefile targets,
scripts/run_tests.sh, pytest config), and which context files
(AGENTS.md / CLAUDE.md / .cursorrules) exist at the root. Marker-only
(non-git) projects get the snapshot too instead of nothing. The
"verify before claiming done" brief line was the highest-value piece
in evals — this turns it from advice into an executable loop instead
of making the model rediscover the test command every session. Still
stat-cheap, size-guarded reads, built once at prompt time.
- Edit-format steering covers the families Hermes actually serves:
Gemini and open-weight coding models (DeepSeek, Qwen, Kimi, GLM,
Grok, Hermes, Llama, Mistral, Devstral, MiniMax) steer to
mode='replace' — their RL scaffolds use str_replace-style editors.
Previously only GPT/Codex and Claude families got steering; the
models Hermes users disproportionately run all fell to neutral.
- Operating brief gains four behaviors elite harnesses encode: batch
independent reads/searches in one turn; fix root causes and the bug
class (sibling call paths), not the reported site; no drive-by
refactors/renames/reformatting; never read, print, or commit secrets.
Plus a patch-failure escalation ladder: after the same region fails
twice, rewrite the enclosing function/file with write_file instead of
a third patch attempt.
- $HOME dotfiles guard: a git repo rooted exactly at the home directory
(or a marker sitting in it, e.g. a global ~/AGENTS.md) is user config,
not a code workspace — without the guard, every session anywhere under
a dotfiles-managed home silently flipped to the coding posture. Real
projects under such a home still detect via their own markers/repos;
'on' mode bypasses the guard.
CI caught tests/cli/test_cli_new_session.py asserting that /new keeps
the old session row when conversation history exists in memory. The
live transcript is authoritative: a session whose messages haven't
flushed to the DB yet (or whose flush failed) must not be pruned.
Guard _discard_session_if_empty on self.conversation_history and pin
the behavior with a test.
Port from google-gemini/gemini-cli#27770: starting the CLI and
immediately quitting (or rotating with /new, /clear) left an empty
untitled session row behind. These ghost rows pile up in /resume,
`hermes sessions list`, and the in-chat recent-sessions browser.
- SessionDB.delete_session_if_empty(): transactional check-and-delete
that only removes rows with no messages, no title, and no child
sessions (delegate subagent parents are preserved). Also removes
on-disk transcript files via the existing _remove_session_files.
- HermesCLI._discard_session_if_empty(): thin wrapper, wired into the
cli_close shutdown path and the new_session() rotation path.
Skipped when /exit --delete already handles removal.
Unlike the one-shot prune_empty_ghost_sessions migration (TUI-only,
24h-old rows), this prevents new ghost rows from accumulating at the
moment they would be created.
Rebased onto current main and re-ported across the restructured
surfaces: model flows now thread confirm_provider/base_url/api_key
through hermes_cli/model_setup_flows.py, the Discord picker lives in
plugins/platforms/discord/adapter.py, and the web dashboard picker
applies chat-mode switches via config.set so the expensive-model
confirmation can ride the response.

Adds memory.write_mode and skills.write_mode (on|off|approve), applied to
both foreground turns and the background self-improvement review fork — the
source of the unprompted 'wrong assumption' saves users reported.
- on (default): write freely, unchanged behaviour
- off: never write; the tool returns a clean disabled result
- approve: don't commit. Memory foreground writes prompt inline (small,
reviewable in a chat bubble); background memory writes and ALL skill writes
stage to a pending store instead (a SKILL.md is too large to review inline,
and a daemon thread can't block on a prompt)
Review staged writes from CLI or any messaging platform:
/memory pending|approve|reject|mode
/skills pending|approve|reject|diff|mode
Skill review respects the size asymmetry: inline you see a one-line gist;
the full unified diff stays out-of-band (/skills diff, dashboard, or the
staged JSON file).
New: tools/write_approval.py (gate + pending store), hermes_cli/
write_approval_commands.py (shared CLI+gateway handlers). Gates wired at the
single entry points memory_tool() and skill_manage(), using the existing
write-origin ContextVar to distinguish foreground from background_review.
The /plugins slash command read from the live PluginManager, which only
knows about *loaded* plugins. A freshly-installed plugin that hadn't been
enabled yet showed 'No plugins installed. Drop plugin directories into
~/.hermes/plugins/' — even though it was on disk and a valid plugin.
Switch to the same disk-discovery path as 'hermes plugins list'
(_discover_all_plugins + enabled/disabled sets + _plugin_status), so an
installed plugin now appears with its activation state ([not enabled],
enabled, or disabled) plus the exact enable command.
Default the quick /plugins view to user-installed plugins and summarize
bundled providers/platforms on one line (the full catalog stays behind
'hermes plugins list') so the output isn't drowned by 60+ bundled
provider plugins.
Native Windows bypassed the destructive-slash modal and fell back to a raw
input() prompt. When the confirm was triggered from the process_loop daemon
thread (the normal case), that input() deadlocked against prompt_toolkit's
main-thread stdin ownership: bare /reset froze with Ctrl-C swallowed, while
/reset now worked only because it skips the prompt. Route native Windows
through the existing call_soon_threadsafe modal path (the same key-binding
channel that already handles normal typing on Windows); keep the stdin
fallback only for the safe no-app / scheduling-failure cases, and clean-cancel
(None) off the main thread on win32 so a degraded path never re-deadlocks.
Addresses #33961
Refs #30768
quiet_mode was being used to suppress tool-result display when
tool_progress_mode was 'off'. But quiet_mode also gates operational
status messages, so users with /verbose + tool-progress off lost all
status output.
Adds a dedicated tool_progress_mode attribute to AIAgent; the
tool_executor result-rendering path gates on tool_progress_mode != 'off'.
The CLI passes its tool_progress_mode through agent setup and the
tool-progress cycle command syncs it onto the live agent.
Fixes#33860.
prompt_toolkit's ANSI parser does not handle OSC escape sequences
(\x1b]...\x07 / \x1b]...\x1b\), which caused Rich's [link=...] markup
to leak raw OSC 8 payload into the banner title after /clear.
Added _OSC_ESCAPE_RE to strip OSC sequences in ChatConsole.print()
before routing through _cprint(). CSI/SGR color sequences are
preserved. Visible text between OSC sequences is kept intact.
Lift the 5 agent-construction/session-resume methods out of HermesCLI into
hermes_cli/cli_agent_setup_mixin.py:CLIAgentSetupMixin. Behavior-neutral; cli.py
14139 -> 13492 LOC.
Methods moved (~647 LOC): _ensure_runtime_credentials, _resolve_turn_agent_config,
_init_agent, _preload_resumed_session, _display_resumed_history. All self.* calls
resolve unchanged via the MRO (HermesCLI(CLIAgentSetupMixin, CLICommandsMixin)).
Import split (same recipe as #41942): 2 neutral deps (sys, _escape) imported at
the mixin module top; 12 cli.py-internal helpers/constants (AIAgent, ChatConsole,
CLI_CONFIG, _cprint, _DIM, _RST, _accent_hex, ...) imported lazily per-method
(from cli import ...) so the mixin never imports cli at module scope -> no cycle.
Repointed one source-inspection change-detector (test_callable_api_key.py) to read
the mixin file where the method now lives.
Lift the `_handle_*_command` cluster (2,077 LOC) out of HermesCLI into
hermes_cli/cli_commands_mixin.py; HermesCLI now inherits CLICommandsMixin so
every self.<handler> call resolves unchanged via the MRO. Behavior-neutral.
Import discipline mirrors gateway/slash_commands.py (PR #41886): neutral deps
imported at the mixin module top level; cli.py-internal helpers/constants
(_cprint, _ACCENT, save_config_value, ...) imported lazily inside each handler
via 'from cli import ...' so the mixin never imports cli at module scope.
cli.py 16215 -> 14139 LOC. One test mock repointed (cli.is_browser_debug_ready
-> hermes_cli.cli_commands_mixin.is_browser_debug_ready).
In classic CLI mode the dangerous-command approval prompt (and the clarify,
sudo, and secret-capture prompts) could fail to render: the user saw
'⏱ Timeout — denying command' after 60s without ever seeing the panel,
making approvals.mode: manual unusable.
Root cause. These prompts run their wait loop on the agent/background thread:
they set modal state that a ConditionalContainer's filter reads, then call
self._invalidate() to repaint so the panel appears. _invalidate() is a
THROTTLED wrapper built for high-frequency background repaints (spinner frames,
streaming) — it (a) returns early while a SIGWINCH resize-recovery is pending,
and (b) otherwise only repaints if 250ms elapsed since the last paint. Under
either condition the modal's entry paint is silently dropped, the
ConditionalContainer never re-evaluates, and the prompt times out unseen.
The throttle never belonged on these paths. Originally the callbacks painted
with a direct self._app.invalidate() and worked; a throttle PR blanket-replaced
every invalidate (including these rare, one-shot, user-blocking modal paints)
with the throttled _invalidate(); a later commit removed an idle 1Hz repaint
that had been masking dropped modal paints, surfacing the bug. Notably the
modal KEY-BINDING handlers (↑/↓/Enter) already paint with a direct
event.app.invalidate(), never the throttle — the background-thread callbacks
were the inconsistent ones.
Fix. Add a small _paint_now() helper that paints directly (guarded for a
missing _app, exception-safe) and route the four modal paths' entry, response,
countdown, and teardown paints through it — matching the key-handler idiom.
This covers approval, clarify, sudo, and the secret-capture teardown
(_submit_secret_response, which previously used the throttled _invalidate() so
its panel could linger after submit). _invalidate() is left untouched and its
docstring now states it is for high-frequency background repaints only;
modal/interactive paints must use _paint_now()/_app.invalidate() directly. This
also fixes the resize-recovery edge case for free (a direct paint never
consults the resize guard) without a throttle-bypass flag that could be
cargo-culted onto hot paths. Countdown refresh cadence tightened 5s->1s so the
timer stays visible while waiting, and a copy-pasted duplicate countdown block
in _clarify_callback is removed.
Tests: TestModalPaintNow drives all three wait-loop callbacks on a background
thread with BOTH gates active (_resize_recovery_pending=True + a recent
_last_invalidate in the throttle window) and asserts the panel paints on entry
AND repaints on teardown; plus a secret-teardown test, a direct
_paint_now-vs-_invalidate gate test, and a no-_app safety test. Each modal test
fails if its paint is reverted to _invalidate(). 17 in-file tests pass; full
tests/cli suite green (900).
Diagnosis credit: the throttle-drop root cause was identified by @sanidhyasin
in #41116; @islam666 independently reached the same direct-invalidate approach
in #41166; original report #41098 by @jodonnel.
process_command() is typed -> bool, but the /clear, /new, and /undo
cancel paths did a bare `return` (None) when _confirm_destructive_slash
was declined, leaking None through the bool contract. Return True
(command handled, keep the REPL alive) on cancel.

* feat(tui): HERMES_DEV_CREDITS live-spend dev readout (L0 tracer for usage-aware credits)
L0 of the usage-aware-credits feature: a dev-only, env-gated tracer that
exercises the real header -> CreditsState -> TUI pipe end-to-end behind
HERMES_DEV_CREDITS, de-risking the L1/L5 build before the notice policy exists.
- agent/credits_tracker.py: CreditsState + parse_credits_headers (headers are
strings -> paid_access via == "true", never bool(); retain-last-known; only
subscription_micros may be negative; *_usd kept verbatim).
- run_agent.py: _capture_credits / get_credits_state / get_credits_spent_micros,
session-start baseline latch, + dev-gated "credits" capture log.
- agent/chat_completion_helpers.py: capture on the streaming response.
- agent/agent_init.py: init _credits_state + _credits_session_start_micros.
- tui_gateway/server.py: _get_usage emits dev_credits_spent_micros only when flagged.
- ui-tui appChrome.tsx / types.ts: cents delta status segment + "(dev credits)" banner.
Off by default; silent for normal users. Validated live against staging
(capture log delta matches the TUI segment). Throwaway consumer (readout/log/
banner); credits_tracker + the capture plumbing are the real feature foundation.
* test(credits): lock parser under 9-state matrix + harden validation (L2)
Add tests/agent/test_credits_tracker.py with 92 tests covering the 9-state
matrix (healthy, sub_90pct, grant_exhausted, purchased_only, tool_pool_free,
depleted, debt, missing, no_org) plus validation edge cases: version strict==1
with warn-once latch for v>1, bool-string trap (paid_access/tool_pool_gated_off
== "true"/"false", never bool()), half-pair subscription limit treated as
both-absent while parse succeeds, USD regex ^-?\d+\.\d{2}$, non-int micros
→ None, negative non-subscription micros → None, as_of_ms junk → None, zero
limit ZeroDivision guard.
Harden agent/credits_tracker.py to match the spec:
- Add tool_pool_micros/tool_pool_gated_off/from_header fields to CreditsState
- Add depleted property (== not paid_access, never remaining==0)
- Change used_fraction guard to key off subscription_limit_micros (the actual
denominator) not denominator_kind (metadata)
- Replace fail-soft _safe_int with a sentinel-returning variant; full validation
now returns None on any malformed field rather than silently defaulting
- Add module-level warn-once latch for version > 1
- Add USD regex validation; add denominator_kind allow-list check
- Parse x-nous-tool-pool-* prefix headers (not x-nous-credits-tool-pool-*)
* feat(credits): notice spine — AgentNotice + notice_callback/notice_clear_callback + TUI binding (L1)
L1 of usage-aware credits: the driver-agnostic notice delivery spine that L4's
policy will fire through and L5's TUI render will consume.
- agent/credits_tracker.py: AgentNotice dataclass (text/level/kind/ttl_ms/key/id;
kind defaults "sticky", kept TTL-expressive for a future config seam).
- run_agent.py: AIAgent gains notice_callback + notice_clear_callback slots and
_emit_notice / _emit_notice_clear emitters (swallow all callback errors — a
notice must never break the agent loop; no-op when unbound).
- agent/agent_init.py: thread both callbacks through init_agent.
- tui_gateway/server.py: bind both in _agent_cbs → notification.show / notification.clear
WS events (snake_case payload, matching the existing gateway-event convention).
- ui-tui/src/gatewayTypes.ts: notification.show / notification.clear arms on GatewayEvent.
- tests/run_agent/test_notice_spine.py: 15 tests (emitter fire + fail-open + no-op,
signature threading, TUI binding payload shape).
Messaging push is out of v1 (binds neither callback). CLI binding + the TUI render/
decode land with L4 (firing) and L5 (render) so turn-end flush is wired correctly.
* feat(credits): threshold reconciliation policy + tests (L4.1)
* feat(credits): wire threshold policy into capture + latch (L4.2)
After a fresh header parse, _capture_credits runs evaluate_credits_notices against
the agent's _credits_latch and emits the result — clears first, then shows (so a
recovered depletion clears before the "restored" success lands, and depleted wins
the latest-wins slot). Gated on a bound notice_callback: messaging (no callbacks)
still caches state for /usage but runs no policy. Parse stays fail-open (miss →
keep last-known); the eval/emit path warns on failure rather than swallowing, so a
depletion-notice bug can't vanish silently.
- run_agent.py: _capture_credits split into parse (swallow→miss) + policy (warn);
latch lazy-guarded (object.__new__ safety).
- agent/agent_init.py: init agent._credits_latch = {"active": set(), "seen_below_90": False}.
* feat(tui): render credits notices in the status bar (L5, Strategy B)
The TUI now renders the notification.show / notification.clear gateway events the
agent emits — a level-colored notice overrides the status/verb slot when not busy.
- Notice state machine on turnController (pendingNotice + dedicated noticeTimer +
show/clear/applyNotice/flushPendingNotice/clearNoticeState). createGatewayEventHandler
decodes the events and delegates.
- Render priority busy > notice > status (appChrome StatusRule); notice text rendered
verbatim (its glyph comes from the policy), shrinkable so it never clips model│ctx;
dev-credits banner + Δ segment preserved. UiState.notice is snake_case (matches wire).
- Busy-wins: a notice arriving mid-turn is held and flushed at the THREE turn-end sites
(recordMessageComplete / interruptTurn / recordError) — never idle(), which reset()
also calls (would leak across sessions); reset() clears instead.
- Dedicated noticeTimer (never statusTimer); TTL starts on visibility with an id-guard;
latest-wins cancels the prior timer; clear is key-matched (no-op on mismatch); a sticky
survives a turn (flush no-ops with no pending); session reset clears (no cross-session leak).
- 20 tests (handler/turnController logic incl. R3-C2 timer isolation + render priority).
* feat(credits): cold-start seed for new Nous sessions (L3)
A genuinely-new Nous session has no inference header yet, so seed credits state from
the authoritative GET /api/oauth/account snapshot at session start (in the new-session
branch of _restore_or_build_system_prompt — inline, since the on_session_start plugin
hook gets no agent reference). The seed runs the shared notice policy, so a session that
opens already depleted warns IMMEDIATELY rather than only after the first turn.
- Maps the nested account fields (paid_service_access → paid_access; total_usable /
subscription / purchased on paid_service_access_info; rollover on subscription), each
None-guarded; float dollars → micros via round(d*1e6), *_usd left "" (render formats
from micros — never synthesize a verbatim usd from a float).
- Magnitudes-only: no monthlyCredits on the endpoint → subscription_limit_* unset →
used_fraction None → no warn90 from the seed (% only once a header lands, per D-E).
- Provider-guarded to Nous; fail-open (any error leaves _credits_state None, never
blocks startup); paid_access unknown ⇒ True (never falsely depleted).
- run_agent.py: extracted the warm-path policy/emit block into a shared
_emit_credits_notices() so capture and the seed fire notices identically.
* feat(credits): /usage Nous credits magnitudes view + recovery trigger (L6)
Add Nous credit dollar magnitudes to /usage (subscription / top-up / total
+ rollover + renewal + portal CTA), magnitudes-only per v1 (no % until the
account endpoint exposes a denominator). Reuses the existing account-usage
render machinery via a new pure build_nous_credits_snapshot() that maps a
NousPortalAccountInfo to an AccountUsageSnapshot; no nous branch is added to
fetch_account_usage (keeps the per-provider boundary intact).
CLI /usage also doubles as a depletion-recovery trigger: a force_fresh
account fetch, kept in a SEPARATE local so it never clobbers the
header-sourced agent._credits_state (which alone carries used_fraction). If
paid access recovered while credits.depleted is latched and a notice
consumer is bound, it reuses agent._emit_credits_notices() to clear it.
Gateway /usage displays magnitudes only — messaging binds no notice
consumer, so it performs no recovery emit.
Fail-open throughout: any portal hiccup leaves /usage unaffected.
* refactor(credits): dedupe HERMES_DEV_CREDITS flag parse via shared helpers
The dev-flag truthy check was inlined in three places. Replace with the shared
utils.is_truthy_value (run_agent.py, tui_gateway/server.py — also drops a
redundant inline `import os`) and a hoisted DEV_CREDITS_MODE export in
ui-tui/src/config/env.ts (consumed by appChrome, which also stops recomputing the
env check on every render). Behaviour-preserving; identical truthy set.
* fix(credits): cut dead /usage recovery trigger + bound portal fetches (L6 review)
Adversarial review found the /usage depletion-recovery trigger dead AND broken:
the CLI binds no notice_clear_callback, the TUI runs /usage in a separate
slash-worker subprocess (its own agent/latch), and the no-clobber rule made it
evaluate stale paid_access anyway. Recovery already happens on the next inference
(warm path), so the trigger was redundant — remove it and stop the depleted
notice over-promising.
- cli.py: remove the dead recovery block; bound the /usage portal fetch with a
10s wall-clock timeout (ThreadPoolExecutor) like the per-provider fetch —
urllib's per-socket timeout is not a wall-clock guarantee.
- agent/credits_tracker.py: reword the depleted CTA to "run /usage for balance"
(no false recovery promise; /usage shows fresh magnitudes, sticky clears next turn).
- agent/conversation_loop.py: same wall-clock timeout on the cold-start seed fetch
so a stalled portal can't hang session startup; tidy its time import.
* chore(credits): dev notice-state fixtures (HERMES_DEV_CREDITS_FIXTURE)
Throwaway dev scaffolding to exercise the notice pipeline without real spend or
Redis seeding. Set HERMES_DEV_CREDITS_FIXTURE to a state name (healthy / sub_90pct
/ grant_exhausted / depleted / clear) or a file path whose contents name a state
(re-read each turn → flip states live for recovery testing). _capture_credits
injects the chosen CreditsState instead of parsing real headers and runs the
shared notice policy. Deletable with the rest of the HERMES_DEV_CREDITS scaffolding.
* feat(credits): /usage monthly-grant % gauge
The portal /api/oauth/account subscription block now carries monthly_credits
(the per-period grant allowance, the % denominator). The consumer parsed
monthly_charge but dropped monthly_credits, so /usage stayed magnitudes-only.
Capture monthly_credits into NousPortalSubscriptionInfo + _subscription_from_payload.
build_nous_credits_snapshot emits a Subscription usage window (real % used, routed
through the existing render machinery) when monthly_credits is a finite positive
denominator and credits_remaining is finite and <= cap; otherwise it degrades to
magnitudes-only (older portals, rollover-over-cap, or non-finite payloads).
Guards (adversarial-review-driven): reject non-finite operands (json.loads parses
bare NaN/Infinity by default → would render $nan + a false 100% used), reject
bools, guard div-by-zero (cap>0), and suppress the gauge when remaining > cap
(rollover spanning the period makes the cap a nonsensical denominator → the
$X-of-$Y detail would read as a contradiction). Debt (remaining<0) clamps to 100%.
Money rule preserved: the ratio + magnitudes are computed from numeric float
account fields via display formatting, never by parsing a server *_usd string
(there are none on these dataclasses).
13 gauge tests added (tests/agent/test_nous_credits_gauge.py).
* fix(credits): show /usage Nous block whenever a Nous account is present
/usage runs in a slash-worker subprocess whose resolved inference provider is
often not "nous" even when the user has a Nous account, so gating the Nous
credits block on (provider == "nous") hid it entirely — the account data was
fully available but never rendered.
Gate instead on "a Nous account is logged in": a cheap local auth-state lookup
(get_provider_auth_state('nous') has an access_token) decides whether to attempt
the portal fetch, regardless of which provider inference runs on. In the gateway
the block is also lifted out of the 'if provider:' scope so a Nous-credentialled
user with another (or no) resident inference provider still sees their balance.
Fail-open and the per-fetch wall-clock timeout are preserved.
* fix(credits): show /usage Nous block when there's no live agent (TUI slash-worker)
In the TUI, /usage runs in a slash-worker subprocess that resumes the session
WITHOUT building an agent (self.agent is None), so _show_usage early-returned
"(._.) No active agent" before ever reaching the Nous credits block — which is
agent-independent (a portal fetch gated on Nous auth-state). Extract the block
into _print_nous_credits_block() and run it at the no-agent / no-calls
early-returns too (returns True if it printed, so the fallback message only
shows when there's genuinely nothing).
Verified live against staging: the block + monthly-grant gauge now render in the
slash-worker /usage path (previously hidden). The plain CLI REPL + messaging
paths are unchanged (they have a live agent).
* feat(credits): escalating 50/75/90 usage bands (single status line)
Replace the lone 90%-used warning with three escalating bands (50 info, 75 warn,
90 warn) shown as ONE status-bar line: it displays the highest band the
subscription grant has crossed, replaces the line as usage climbs, steps back
down on recovery, and clears below 50%. No stacking, no per-turn churn.
Bands live in a tunable CREDITS_USAGE_BANDS list; the policy derives everything
from it. Single notice key (credits.usage) with a usage_band latch field so the
notice only re-emits when the band actually changes. The crossing gate
(seen_below_90) is preserved so a fresh live session that opens mid-range stays
quiet until it has been observed below the lowest band (cold-start primes it when
it wants an open-high warning). Denominator math unchanged: % = subscription
grant burn (cap - grant_remaining)/cap, clamped [0,1]; top-up never moves the %.
Migrated test_credits_policy.py to the new key + added TestUsageBands (climb,
step-down, recovery-clear, idempotent, inclusive boundaries).
* feat(credits): hydrate notices at session OPEN via shared seed (TUI + first-turn)
Notices previously only fired inside a conversation turn (first message), so a
session that opened already depleted / past a usage band showed nothing at
'ready'. Extract the cold-start seed into a shared seed_credits_at_session_start()
and call it (a) in the TUI/desktop agent build right after the notice callback is
wired (fires at 'ready', before any message) and (b) as the first-turn fallback in
conversation_loop. Idempotent (skips once _credits_state exists) and fail-open.
The seed now maps monthly_credits -> subscription_limit_micros +
denominator_kind='subscription_cap', so used_fraction is computable at seed time
and usage-band warnings (not just depletion) hydrate on open. Primes the crossing
latch so a session opening already in a band warns immediately. Degrades to
depletion-only when monthly_credits is absent (older portals).
Adds test_credits_cold_start.py covering open-at-band, depletion, debt, no-cap
degradation, and the shared seed (fires/idempotent/skips-non-nous).
* feat(credits): /usage monthly-grant % gauge + fixture support + TUI surfacing
agent/account_usage.py: build_nous_credits_snapshot emits a subscription %% gauge
when the portal supplies a positive, finite monthly_credits denominator with
remaining <= cap (guards reject NaN/Infinity and rollover-over-cap, which would
render $nan or a contradictory $X-of-$Y); degrades to magnitudes-only otherwise.
Adds shared nous_credits_lines() (auth-gated, wall-clock-bounded portal fetch) so
the CLI and TUI /usage render the same block, and _snapshot_from_credits_state()
so HERMES_DEV_CREDITS_FIXTURE drives /usage offline too.
TUI: session.usage RPC carries credits_lines (agent-independent) and the /usage
panel renders them regardless of API-call count or resume state — previously the
TUI's separate /usage implementation only showed token counts.
Money rule preserved: %% and magnitudes come from numeric float account fields via
display formatting, never by parsing a server *_usd string.
* feat(credits): CLI REPL inline notices (parity with TUI)
The plain CLI agent bound no notice callbacks, so credit notices were TUI-only.
Bind notice_callback/notice_clear_callback on the CLI AIAgent; _on_notice renders
a single level-colored line above the prompt (error red / warn yellow / success
green / info dim) via _cprint, and seed credits at session open so a depletion or
usage-band warning shows before the first message — the same hydration the TUI
got. _on_notice_clear is a no-op (the REPL prints lines, no persistent slot).
* test(credits): add sub_50pct + sub_75pct dev fixtures for the new usage bands
The fixture set jumped 10%% -> 90%%; add sub_50pct (uf 0.5 -> band 50 info) and
sub_75pct (uf 0.75 -> band 75 warn) so the new escalating bands are exercisable
via HERMES_DEV_CREDITS_FIXTURE across all three surfaces (notice, session-open
seed, /usage gauge).
* fix(credits): usage-band notice clears on next prompt (not sticky-forever)
A 50/75/90 usage heads-up was sticky and camped the status bar indefinitely. Clear
the visible credits.usage notice when a new turn starts (startMessage), so it shows
until your next prompt then yields. The server latch is unchanged, so it won't
re-nag at the same band — it only re-shows when the band actually changes (climb)
or clears when usage drops below the lowest band. Depletion stays sticky.
* refactor(credits): consolidate the /usage credits block behind nous_credits_lines()
The CLI (_print_nous_credits_block) and the messaging gateway (_handle_usage_command)
each re-implemented the auth-gate + portal fetch + render, and both bypassed the
dev-fixture short-circuit that only the TUI honored — so /usage ignored
HERMES_DEV_CREDITS_FIXTURE on the CLI and in chat. Route both through the shared
agent.account_usage.nous_credits_lines() helper: one fetch/render path, one auth
gate, and the fixture works on every surface (~60 fewer duplicated lines).
The gateway usage test recorded only the last asyncio.to_thread call; /usage now
dispatches both the account fetch and the credits fetch, so it records every call
and matches the account fetch by its provider arg.
* fix(credits): keep the /usage gauge type-safe and log its fail-open path
_is_finite_num is now a TypeGuard[float], so the type checker narrows the gauge
operands (monthly_credits / credits_remaining) and the magnitudes passed to
_fmt_usd through it — no more None-operand warnings on the arithmetic. Add a debug
breadcrumb on the nous_credits_lines portal-fetch fail-open so a dead /usage block
is diagnosable in agent.log without a dev flag.
* fix(credits): harden the header tracker — prod-leak gate, hot-path probe, fire-and-forget seed
- Prod-leak guard: dev fixtures (HERMES_DEV_CREDITS_FIXTURE) now also require
HERMES_DEV_CREDITS, so a stray fixture var can't surface fabricated balances on a
real account. Matches the documented run workflow (both vars set together).
- Hot-path probe: parse_credits_headers checks for the version sentinel header
before allocating a lowercased copy of the response headers — skips that work on
every non-Nous API call. Behaviour-identical and still case-insensitive.
- Fire-and-forget seed: the real portal fetch in seed_credits_at_session_start now
runs in a daemon thread, so a slow/unreachable portal never delays session "ready"
(previously blocked up to 10s). The dev-fixture path stays synchronous; the thread
re-checks idempotency before hydrating (a live header may land first).
- Diagnostics: debug breadcrumbs on the parse and seed fail-open paths so a crashed
parser / dead seed is distinguishable from a legitimate no-headers miss.
Cold-start tests set HERMES_DEV_CREDITS alongside the fixture to match the gate.
* test(tui): fix env-timing in the StatusRule dev-credits assertion
DEV_CREDITS_MODE is read once at module load (config/env), so mutating
process.env.HERMES_DEV_CREDITS inside the test couldn't flip it — the dev-banner
assertion only passed if the env was exported before vitest started, and failed in a
normal run. Move that assertion to a sibling file that mocks config/env with
DEV_CREDITS_MODE: true (scoped, no module-reset / React-identity hazard).
* test(credits): cover the dev-fixture /usage render and usage-band clear-on-prompt
- _snapshot_from_credits_state (the offline /usage renderer) had no direct test:
lock the gauge math, the verbatim *_usd magnitudes, the depletion line and the
fixture marker, plus the no-cap (no gauge) and None-state cases.
- turnController.startMessage had no test for clearing the credits.usage notice on
the next prompt while leaving credits.depleted sticky.
* feat(credits): deliver credit notices over messaging gateways
Bind notice_callback/notice_clear_callback on the per-turn gateway agent
so usage-band / depletion / restored notices reach Telegram/Discord/Slack/
etc. Previously the messaging gateway bound neither callback, so the agent's
_emit_credits_notices early-returned and a chat user crossing a band got
nothing unless they ran /usage manually.
- render_notice_line(): AgentNotice -> single plaintext line (level glyph +
text), plaintext-only so it renders uniformly without per-platform escaping.
Fail-soft on malformed/empty notices.
- Standalone push for every notice (messaging has no persistent status bar):
route through the shared _deliver_platform_notice rail (honors private/
public delivery + thread metadata), scheduled onto the gateway loop via
safe_schedule_threadsafe from the agent's sync worker thread — same pattern
as _status_callback_sync.
- The fired-once latch lives on the cached (reused-in-place) agent and
persists across turns, so a band crosses once -> one push, no per-turn
re-nag. Re-fires only after idle-eviction rebuilds the agent (a reminder).
- Recovery ('Credit access restored') rides the show path (emitted as a
success notice, not a clear). notice_clear_callback is a no-op: a sent
platform message can't be cleanly retracted.
Tests: render glyph/levels/fail-soft + public/private delivery seam through
_deliver_platform_notice + no-adapter no-op.
* fix(credits): don't double the glyph on messaging notices
render_notice_line prepended a per-level glyph, but the notice policy already
bakes the glyph into the text (and the TUI + CLI render it verbatim) — so every
credit notice over messaging came out doubled ("⚠ ⚠ Credits 90% used",
"⛔ ✕ Credit access paused"). Emit the text verbatim instead; drop the now-dead
level→glyph map.
The render tests fed glyph-less text (and the success case only checked
startswith), so the doubling slipped through. Rework them around the verbatim
contract and add an end-to-end regression that runs real evaluate_credits_notices
output through render_notice_line and asserts the line is returned unchanged.
* fix: respect disabled auto-compaction on context overflow
Port from anomalyco/opencode#30749.
When compression.enabled is false, NO automatic compaction trigger may
fire. The proactive token-threshold paths (preflight + post-response
should_compress gate) already honoured the setting, but the three
provider-overflow recovery paths in the agent loop — long-context-tier
429, 413 payload-too-large, and context-overflow — called
_compress_context() unconditionally, silently compressing and rotating
the session against the user's explicit choice.
Add a single guard at the top of the overflow-recovery dispatch: when
compression is disabled and the error is one of those three overflow
classes, surface a terminal error (compaction_disabled: True) telling the
user to /compress manually, /new, switch to a larger-context model, or
reduce attachments. Manual /compress (force=True) is unaffected — it never
enters this loop.
Tests: new TestOverflowWithCompactionDisabled (413 + 400 overflow don't
compress when disabled; control case still compresses when enabled).
Existing overflow-recovery tests updated to enable compaction explicitly
(they verify the recovery fires); fixture defaults flipped to True to
match production (compression.enabled defaults to True).
* perf(/model): prewarm picker provider-models cache in background
The no-args /model picker calls list_authenticated_providers(), which
fetches each authenticated provider's live /v1/models list serially. On a
cold or stale (>1h TTL) cache that blocks ~1.5s on the user's critical path
the first time /model is opened in a session.
Warm that exact path off-thread during the idle window right after the CLI
banner is shown: a once-per-process daemon thread runs
list_authenticated_providers() to populate provider_models_cache.json for
every authed provider. By the time the user types /model, the picker hits
the warm disk cache (~136ms vs ~1500ms).
Process-level Event guard (mirrors run_agent's _openrouter_prewarm_done)
ensures at most one thread per process; fully exception-isolated so an
offline/no-creds provider can never affect the session.
Replace [{_DIM}] with [dim] in all _restore_session_cwd and
_preload_resumed_session messages that go through _console_print (Rich
Console.print). _DIM is an ANSI escape (\x1b[2;3m) that Rich cannot
parse as a markup tag, causing MarkupError on session resume when the
stored cwd is missing or inaccessible.
Also uses [/dim] closing tag for explicit tag matching.
Fixes#39469
/branch (aka /fork) sessions vanished from /resume and /sessions. Both
surfaces funnel through list_sessions_rich(include_children=False), which
hid any session with a parent_session_id unless identified as a branch via a
heuristic — parent.end_reason == 'branched' AND child.started_at >=
parent.ended_at.
Two ways that heuristic failed:
1. CLI/gateway branches: once the parent was reopened (e.g. resumed) and
re-ended with a different end_reason (tui_shutdown overwriting 'branched'),
the heuristic stopped matching and the branch was hidden permanently.
2. TUI branches (tui_gateway session.branch): the TUI never ends the parent
as 'branched' — it creates the child while the parent is still live — so
the heuristic NEVER matched and TUI branches were hidden from the moment
they were created (this is the macOS desktop app's primary symptom).
Fix: persist a stable '_branched_from' marker in the branch session's
model_config at creation time across ALL THREE branch paths (CLI cli.py,
gateway gateway/run.py, and TUI tui_gateway/server.py), and OR a
json_extract(model_config, '$._branched_from') IS NOT NULL check into the
list_sessions_rich filter. The marker is immutable across the parent's
lifecycle, so the branch stays visible regardless of how/whether the parent
is ended. The legacy end_reason heuristic is kept (OR'd) so pre-existing
branches remain visible. Subagent/compression children (no marker, parent
not 'branched') stay correctly hidden. Fixes#20856.
Approach by liuhao1024 (PR #20864); reimplemented on current main, extended
to the TUI branch path (which the original missed), with regression tests for
the reopen+re-end scenario and the TUI marker persistence.
The classic CLI left its live bottom chrome — the status bar, input box,
and separator rules — frozen in terminal scrollback after exit, on every
exit path (/exit, /quit, Ctrl+C, EOF) and on both Linux and Windows. The
prior erase_when_done=True fix (bf82a7f1c) routes prompt_toolkit's teardown
through renderer.erase(), but that walks back by the renderer's internal
cursor model and does not reliably wipe the chrome in practice — users still
saw a dead status bar + the rest of the session sitting above the resume
summary.
Clear the screen + scrollback directly at the single exit funnel instead.
All exit paths converge on _print_exit_summary() (called from the run-loop
finally block after app.run() returns and prompt_toolkit has restored
terminal modes), so a new _clear_terminal_on_exit() helper runs there before
the summary prints. It writes ESC[3J ESC[2J ESC[H (erase scrollback, erase
screen, home cursor) on a real TTY, no-ops silently when stdout is not a
terminal (pipes/redirects), and falls back to the platform clear command if
the escape write fails. Works on Linux, macOS, and modern Windows terminals
(Terminal/conhost with VT processing, already enabled by prompt_toolkit).
The resume/goodbye summary now prints at a clean top-left with nothing
stranded above it.
Fixes#38252.
Sets erase_when_done=True on the classic CLI's prompt_toolkit Application so the
live bottom chrome (status bar, input box, separator rules) is wiped on exit
instead of frozen into scrollback.
Previously prompt_toolkit's render_as_done teardown repainted the chrome one
final time and left it on screen (ESC[J only erases below the cursor, not the
chrome above), so a dead status bar + empty prompt + rules were stranded
between the conversation transcript and the 'Resume this session' summary, and
stacked with the next session's UI on resume. erase_when_done routes teardown
through renderer.erase() which wipes exactly the managed chrome region; the
conversation transcript prints through patch_stdout into normal scrollback and
is untouched. Applies to every exit path (/exit, /quit, EOF, Ctrl+C).
Fixes#38252.
