New and newer models from models.dev now surface automatically in
/model (both hermes model CLI and the gateway Telegram/Discord picker)
for a curated set of secondary providers — no Hermes release required
when the registry publishes a new model.
Primary user-visible fix: on OpenCode Go, typing '/model mimo-v2.5-pro'
no longer silently fuzzy-corrects to 'mimo-v2-pro'. The exact match
against the merged models.dev catalog wins.
Scope (opt-in frozenset _MODELS_DEV_PREFERRED in hermes_cli/models.py):
opencode-go, opencode-zen, deepseek, kilocode, fireworks, mistral,
togetherai, cohere, perplexity, groq, nvidia, huggingface, zai,
gemini, google.
Explicitly NOT merged:
- openrouter and nous (never): curated list is already a hand-picked
subset / Portal is source of truth.
- xai, xiaomi, minimax, minimax-cn, kimi-coding, kimi-coding-cn,
alibaba, qwen-oauth (per-project decision to keep curated-only).
- providers with dedicated live-endpoint paths (copilot, anthropic,
ai-gateway, ollama-cloud, custom, stepfun, openai-codex) — those
paths already handle freshness themselves.
Changes:
- hermes_cli/models.py: add _MODELS_DEV_PREFERRED + _merge_with_models_dev
helper. provider_model_ids() branches on the set at its curated-fallback
return. Merge is models.dev-first, curated-only extras appended,
case-insensitive dedup, graceful fallback when models.dev is offline.
- hermes_cli/model_switch.py: list_authenticated_providers() calls the
same merge in both its code paths (PROVIDER_TO_MODELS_DEV loop +
HERMES_OVERLAYS loop). Picker AND validation-fallback both see
fresh entries.
- tests/hermes_cli/test_models_dev_preferred_merge.py (new): 13 tests —
merge-helper unit tests (empty/raise/order/dedup), opencode-go/zen
behavior, openrouter+nous explicitly guarded from merge.
- tests/hermes_cli/test_opencode_go_in_model_list.py: converted from
snapshot-style assertion to a behavior-based floor check, so it
doesn't break when models.dev publishes additional opencode-go
entries.
Addresses a report from @pfanis via Telegram: newer Xiaomi variants
on OpenCode Go weren't appearing in the /model picker, and /model
was silently routing requests for new variants to older ones.
Plugin slash commands now surface as first-class commands in every gateway
enumerator — Discord native slash picker, Telegram BotCommand menu, Slack
/hermes subcommand map — without a separate per-platform plugin API.
The existing 'command:<name>' gateway hook gains a decision protocol via
HookRegistry.emit_collect(): handlers that return a dict with
{'decision': 'deny'|'handled'|'rewrite'|'allow'} can intercept slash
command dispatch before core handling runs, unifying what would otherwise
have been a parallel 'pre_gateway_command' hook surface.
Changes:
- gateway/hooks.py: add HookRegistry.emit_collect() that fires the same
handler set as emit() but collects non-None return values. Backward
compatible — fire-and-forget telemetry hooks still work via emit().
- hermes_cli/plugins.py: add optional 'args_hint' param to
register_command() so plugins can opt into argument-aware native UI
registration (Discord arg picker, future platforms).
- hermes_cli/commands.py: add _iter_plugin_command_entries() helper and
merge plugin commands into telegram_bot_commands() and
slack_subcommand_map(). New is_gateway_known_command() recognizes both
built-in and plugin commands so the gateway hook fires for either.
- gateway/platforms/discord.py: extract _build_auto_slash_command helper
from the COMMAND_REGISTRY auto-register loop and reuse it for
plugin-registered commands. Built-in name conflicts are skipped.
- gateway/run.py: before normal slash dispatch, call emit_collect on
command:<canonical> and honor deny/handled/rewrite/allow decisions.
Hook now fires for plugin commands too.
- scripts/release.py: AUTHOR_MAP entry for @Magaav.
- Tests: emit_collect semantics, plugin command surfacing per platform,
decision protocol (deny/handled/rewrite/allow + non-dict tolerance),
Discord plugin auto-registration + conflict skipping, is_gateway_known_command.
Salvaged from #14131 (@Magaav). Original PR added a parallel
'pre_gateway_command' hook and a platform-keyed plugin command
registry; this re-implementation reuses the existing 'command:<name>'
hook and treats plugin commands as platform-agnostic so the same
capability reaches Telegram and Slack without new API surface.

Copilot on #14138 flagged that the share report says '(file not found)'
when the log exists but is empty (either because the primary is empty
and no .1 rotation exists, or in the rare race where the file is
truncated between _resolve_log_path() and stat()).
- Split _primary_log_path() out of _resolve_log_path so both can share
the LOG_FILES/home math without duplication.
- _capture_log_snapshot now reports '(file empty)' when the primary
path exists on disk with zero bytes, and keeps '(file not found)'
for the truly-missing case.
Tests: rename test_returns_none_for_empty → test_empty_primary_reports_file_empty
with the new assertion, plus a race-path test that monkeypatches
_resolve_log_path to exercise the size==0 branch directly.
Drop rebased test assumptions about theme-mode helpers removed on main and keep the status bar skin integration aligned with the current skin engine model.
Route prompt_toolkit status bar colors through the skin engine so /skin updates the status bar alongside the rest of the interactive TUI.
Add regression coverage for the new status bar style override keys and CLI style composition.
These thin wrappers around _capture_log_snapshot had zero production
callers after the snapshot refactor — run_debug_share uses snapshots
directly and collect_debug_report captures internally. The wrappers
also caused a performance regression: _read_log_tail read up to 512KB
and built full_text just to return tail_text.
Remove both wrappers and migrate TestReadFullLog → TestCaptureLogSnapshot
to test _capture_log_snapshot directly. Same coverage, tests the real
API instead of dead indirection.
Add missing AUTHOR_MAP entry for taosiyuan163 whose truncation boundary
fix was adapted into _capture_log_snapshot().
Add regression tests proving: line-boundary truncation keeps the full
first line, mid-line truncation correctly drops the partial fragment.
* fix(plugins): auto-coerce user-installed memory plugins to kind=exclusive
User-installed memory provider plugins at $HERMES_HOME/plugins/<name>/
were being dispatched to the general PluginManager, which has no
register_memory_provider method on PluginContext. Every startup logged:
Failed to load plugin 'mempalace': 'PluginContext' object has no
attribute 'register_memory_provider'
Bundled memory providers were already skipped via skip_names={memory,
context_engine} in discover_and_load, but user-installed ones weren't.
Fix: _parse_manifest now scans the plugin's __init__.py source for
'register_memory_provider' or 'MemoryProvider' (same heuristic as
plugins/memory/__init__.py:_is_memory_provider_dir) and auto-coerces
kind to 'exclusive' when the manifest didn't declare one explicitly.
This routes the plugin to plugins/memory discovery instead of the
general loader.
The escape hatch: if a manifest explicitly declares kind: standalone,
the heuristic doesn't override it.
Reported by Uncle HODL on Discord.
* fix(nous): actionable CLI message when Nous 401 refresh fails
Mirrors the Anthropic 401 diagnostic pattern. When Nous returns 401
and the credential refresh (_try_refresh_nous_client_credentials)
also fails, the user used to see only the raw APIError. Now prints:
🔐 Nous 401 — Portal authentication failed.
Response: <truncated body>
Most likely: Portal OAuth expired, account out of credits, or
agent key revoked.
Troubleshooting:
• Re-authenticate: hermes login --provider nous
• Check credits / billing: https://portal.nousresearch.com
• Verify stored credentials: $HERMES_HOME/auth.json
• Switch providers temporarily: /model <model> --provider openrouter
Addresses the common 'my hermes model hangs' pattern where the user's
Portal OAuth expired and the CLI gave no hint about the next step.
Adds schema v7 'api_call_count' column. run_agent.py increments it by 1
per LLM API call, web_server analytics SQL aggregates it, frontend uses
the real counter instead of summing sessions.
The 'API Calls' card on the analytics dashboard previously displayed
COUNT(*) from the sessions table — the number of conversations, not
LLM requests. Each session makes 10-90 API calls through the tool loop,
so the reported number was ~30x lower than real.
Salvaged from PR #10140 (@kshitijk4poor). The cache-token accuracy
portions of the original PR were deferred — per-provider analytics is
the better path there, since cache_write_tokens and actual_cost_usd
are only reliably available from a subset of providers (Anthropic
native, Codex Responses, OpenRouter with usage.include).
Tests:
- schema_version v7 assertion
- migration v2 -> v7 adds api_call_count column with default 0
- update_token_counts increments api_call_count by provided delta
- absolute=True sets api_call_count directly
- /api/analytics/usage exposes total_api_calls in totals
Adds a first-class 'stepfun' API-key provider surfaced as Step Plan:
- Support Step Plan setup for both International and China regions
- Discover Step Plan models live from /step_plan/v1/models, with a
small coding-focused fallback catalog when discovery is unavailable
- Thread StepFun through provider metadata, setup persistence, status
and doctor output, auxiliary routing, and model normalization
- Add tests for provider resolution, model validation, metadata
mapping, and StepFun region/model persistence

* feat(plugins): pluggable image_gen backends + OpenAI provider
Adds a ImageGenProvider ABC so image generation backends register as
bundled plugins under `plugins/image_gen/<name>/`. The plugin scanner
gains three primitives to make this work generically:
- `kind:` manifest field (`standalone` | `backend` | `exclusive`).
Bundled `kind: backend` plugins auto-load — no `plugins.enabled`
incantation. User-installed backends stay opt-in.
- Path-derived keys: `plugins/image_gen/openai/` gets key
`image_gen/openai`, so a future `tts/openai` cannot collide.
- Depth-2 recursion into category namespaces (parent dirs without a
`plugin.yaml` of their own).
Includes `OpenAIImageGenProvider` as the first consumer (gpt-image-1.5
default, plus gpt-image-1, gpt-image-1-mini, DALL-E 3/2). Base64
responses save to `$HERMES_HOME/cache/images/`; URL responses pass
through.
FAL stays in-tree for this PR — a follow-up ports it into
`plugins/image_gen/fal/` so the in-tree `image_generation_tool.py`
slims down. The dispatch shim in `_handle_image_generate` only fires
when `image_gen.provider` is explicitly set to a non-FAL value, so
existing FAL setups are untouched.
- 41 unit tests (scanner recursion, kind parsing, gate logic,
registry, OpenAI payload shapes)
- E2E smoke verified: bundled plugin autoloads, registers, and
`_handle_image_generate` routes to OpenAI when configured
* fix(image_gen/openai): don't send response_format to gpt-image-*
The live API rejects it: 'Unknown parameter: response_format'
(verified 2026-04-21 with gpt-image-1.5). gpt-image-* models return
b64_json unconditionally, so the parameter was both unnecessary and
actively broken.
* feat(image_gen/openai): gpt-image-2 only, drop legacy catalog
gpt-image-2 is the latest/best OpenAI image model (released 2026-04-21)
and there's no reason to expose the older gpt-image-1.5 / gpt-image-1 /
dall-e-3 / dall-e-2 alongside it — slower, lower quality, or awkward
(dall-e-2 squares only). Trim the catalog down to a single model.
Live-verified end-to-end: landscape 1536x1024 render of a Moog-style
synth matches prompt exactly, 2.4MB PNG saved to cache.
* feat(image_gen/openai): expose gpt-image-2 as three quality tiers
Users pick speed/fidelity via the normal model picker instead of a
hidden quality knob. All three tier IDs resolve to the single underlying
gpt-image-2 API model with a different quality parameter:
gpt-image-2-low ~15s fast iteration
gpt-image-2-medium ~40s default
gpt-image-2-high ~2min highest fidelity
Live-measured on OpenAI's API today: 15.4s / 40.8s / 116.9s for the
same 1024x1024 prompt.
Config:
image_gen.openai.model: gpt-image-2-high
# or
image_gen.model: gpt-image-2-low
# or env var for scripts/tests
OPENAI_IMAGE_MODEL=gpt-image-2-medium
Live-verified end-to-end with the low tier: 18.8s landscape render of a
golden retriever in wildflowers, vision-confirmed exact match.
* feat(tools_config): plugin image_gen providers inject themselves into picker
'hermes tools' → Image Generation now shows plugin-registered backends
alongside Nous Subscription and FAL.ai without tools_config.py needing
to know about them. OpenAI appears as a third option today; future
backends appear automatically as they're added.
Mechanism:
- ImageGenProvider gains an optional get_setup_schema() hook
(name, badge, tag, env_vars). Default derived from display_name.
- tools_config._plugin_image_gen_providers() pulls the schemas from
every registered non-FAL plugin provider.
- _visible_providers() appends those rows when rendering the Image
Generation category.
- _configure_provider() handles the new image_gen_plugin_name marker:
writes image_gen.provider and routes to the plugin's list_models()
catalog for the model picker.
- _toolset_needs_configuration_prompt('image_gen') stops demanding a
FAL key when any plugin provider reports is_available().
FAL is skipped in the plugin path because it already has hardcoded
TOOL_CATEGORIES rows — when it gets ported to a plugin in a follow-up
PR the hardcoded rows go away and it surfaces through the same path
as OpenAI.
Verified live: picker shows Nous Subscription / FAL.ai / OpenAI.
Picking OpenAI prompts for OPENAI_API_KEY, then shows the
gpt-image-2-low/medium/high model picker sourced from the plugin.
397 tests pass across plugins/, tools_config, registry, and picker.
* fix(image_gen): close final gaps for plugin-backend parity with FAL
Two small places that still hardcoded FAL:
- hermes_cli/setup.py status line: an OpenAI-only setup showed
'Image Generation: missing FAL_KEY'. Now probes plugin providers
and reports '(OpenAI)' when one is_available() — or falls back to
'missing FAL_KEY or OPENAI_API_KEY' if nothing is configured.
- image_generate tool schema description: said 'using FAL.ai, default
FLUX 2 Klein 9B'. Rewrote provider-neutral — 'backend and model are
user-configured' — and notes the 'image' field can be a URL or an
absolute path, which the gateway delivers either way via
extract_local_files().
Wire the auxiliary client (compaction, vision, session search, web extract)
to the Nous Portal's curated recommended-models endpoint when running on
Nous Portal, with a TTL-cached fetch that mirrors how we pull /models for
pricing.
hermes_cli/models.py
- fetch_nous_recommended_models(portal_base_url, force_refresh=False)
10-minute TTL cache, keyed per portal URL (staging vs prod don't
collide). Public endpoint, no auth required. Returns {} on any
failure so callers always get a dict.
- get_nous_recommended_aux_model(vision, free_tier=None, ...)
Tier-aware pick from the payload:
- Paid tier → paidRecommended{Vision,Compaction}Model, falling back
to freeRecommended* when the paid field is null (common during
staged rollouts of new paid models).
- Free tier → freeRecommended* only, never leaks paid models.
When free_tier is None, auto-detects via the existing
check_nous_free_tier() helper (already cached 3 min against
/api/oauth/account). Detection errors default to paid so we never
silently downgrade a paying user.
agent/auxiliary_client.py — _try_nous()
- Replaces the hardcoded xiaomi/mimo free-tier branch with a single call
to get_nous_recommended_aux_model(vision=vision).
- Falls back to _NOUS_MODEL (google/gemini-3-flash-preview) when the
Portal is unreachable or returns a null recommendation.
- The Portal is now the source of truth for aux model selection; the
xiaomi allowlist we used to carry is effectively dead.
Tests (15 new)
- tests/hermes_cli/test_models.py::TestNousRecommendedModels
Fetch caching, per-portal keying, network failure, force_refresh;
paid-prefers-paid, paid-falls-to-free, free-never-leaks-paid,
auto-detect, detection-error → paid default, null/blank modelName
handling.
- tests/agent/test_auxiliary_client.py::TestNousAuxiliaryRefresh
_try_nous honors Portal recommendation for text + vision, falls
back to google/gemini-3-flash-preview on None or exception.
Behavior won't visibly change today — both tier recommendations currently
point at google/gemini-3-flash-preview — but the moment the Portal ships
a better paid recommendation, subscribers pick it up within 10 minutes
without a Hermes release.
Drop _NOUS_ALLOWED_FREE_MODELS + filter_nous_free_models and its two call
sites. Whatever Nous Portal prices as free now shows up in the picker as-is
— no local allowlist gatekeeping. Free-tier partitioning (paid vs free in
the menu) still runs via partition_nous_models_by_tier.
Follow-ups after salvaging xiaoqiang243's kimi-for-coding patches:
- KIMI_CODE_BASE_URL: drop trailing /v1 (was /coding/v1).
The /coding endpoint speaks Anthropic Messages, and the Anthropic SDK
appends /v1/messages internally. /coding/v1 + SDK suffix produced
/coding/v1/v1/messages (a 404). /coding + SDK suffix now yields
/coding/v1/messages correctly.
- kimi-coding ProviderConfig: keep legacy default api.moonshot.ai/v1 so
non-sk-kimi- moonshot keys still authenticate. sk-kimi- keys are
already redirected to api.kimi.com/coding via _resolve_kimi_base_url.
- doctor.py: update Kimi UA to claude-code/0.1.0 (was KimiCLI/1.30.0)
and rewrite /coding base URLs to /coding/v1 for the /models health
check (Anthropic surface has no /models).
- test_kimi_env_vars: accept KIMI_CODING_API_KEY as a secondary env var.
E2E verified:
sk-kimi-<key> → https://api.kimi.com/coding/v1/messages (Anthropic)
sk-<legacy> → https://api.moonshot.ai/v1/chat/completions (OpenAI)
UA: claude-code/0.1.0, x-api-key: <sk-kimi-*>
Adds role='leaf'|'orchestrator' to delegate_task. With max_spawn_depth>=2,
an orchestrator child retains the 'delegation' toolset and can spawn its
own workers; leaf children cannot delegate further (identical to today).
Default posture is flat — max_spawn_depth=1 means a depth-0 parent's
children land at the depth-1 floor and orchestrator role silently
degrades to leaf. Users opt into nested delegation by raising
max_spawn_depth to 2 or 3 in config.yaml.
Also threads acp_command/acp_args through the main agent loop's delegate
dispatch (previously silently dropped in the schema) via a new
_dispatch_delegate_task helper, and adds a DelegateEvent enum with
legacy-string back-compat for gateway/ACP/CLI progress consumers.
Config (hermes_cli/config.py defaults):
delegation.max_concurrent_children: 3 # floor-only, no upper cap
delegation.max_spawn_depth: 1 # 1=flat (default), 2-3 unlock nested
delegation.orchestrator_enabled: true # global kill switch
Salvaged from @pefontana's PR #11215. Overrides vs. the original PR:
concurrency stays at 3 (PR bumped to 5 + cap 8 — we keep the floor only,
no hard ceiling); max_spawn_depth defaults to 1 (PR defaulted to 2 which
silently enabled one level of orchestration for every user).

The prior form of this test asserted on CLI_CONFIG["delegation"] after
importing cli, which only passed by accident of pytest-xdist worker
scheduling. cli._hermes_home is frozen at module import time (cli.py:76),
before the tests/conftest.py autouse HERMES_HOME-isolation fixture can
fire, so CLI_CONFIG ends up populated by deep-merging the contributor's
actual ~/.hermes/config.yaml over the defaults (cli.py:359-366). Any
contributor (like me) who still has the legacy key set in their own
config causes a false failure the moment another test file in the same
xdist worker imports cli at module level.
Asserting on the source of load_cli_config() instead sidesteps all of
that: the test now checks the defaults literal directly and is
independent of user config, HERMES_HOME, import order, and worker
scheduling.
Demonstrated failure mode before this fix:
pytest tests/hermes_cli/test_config_drift.py \
tests/hermes_cli/test_skills_hub.py -o addopts=""
-> FAILED (CLI_CONFIG["delegation"] contained "default_toolsets"
from the user's ~/.hermes/config.yaml)
Part of Initiative 2 / M0.5.
delegation.default_toolsets was declared in cli.py's CLI_CONFIG default
dict and documented in cli-config.yaml.example, but never read: none of
tools/delegate_tool.py, _load_config(), or any call site ever looked it
up. The live fallback is the DEFAULT_TOOLSETS module constant at
tools/delegate_tool.py:101, which stays as-is.
hermes_cli/config.py's DEFAULT_CONFIG["delegation"] already omits the
key — this commit aligns cli.py with that.
Adds a regression test in tests/hermes_cli/test_config_drift.py so a
future refactor that re-adds the key without wiring it up to
_load_config() fails loudly.
Part of Initiative 2 / M0.5.
Reported during TUI v2 blitz testing: typing `@folder:` in the composer
pulled up .dockerignore, .env, .gitignore, and every other file in the
cwd alongside the actual directories. The completion loop yielded every
entry regardless of the explicit prefix and auto-rewrote each completion
to @file: vs @folder: based on is_dir — defeating the user's choice.
Also fixed a pre-existing adjacent bug: a bare `@file:` or `@folder:`
(no path) used expanded=="." as both search_dir AND match_prefix,
filtering the list to dotfiles only. When expanded is empty or ".",
search in cwd with no prefix filter.
- want_dir = prefix == "@folder:" drives an explicit is_dir filter
- preserve the typed prefix in completion text instead of rewriting
- three regression tests cover: folder-only, file-only, and the bare-
prefix case where completions keep the `@folder:` prefix
DNS rebinding attack: a victim browser that has the dashboard (or the
WhatsApp bridge) open could be tricked into fetching from an
attacker-controlled hostname that TTL-flips to 127.0.0.1. Same-origin
and CORS checks don't help — the browser now treats the attacker origin
as same-origin with the local service. Validating the Host header at
the app layer rejects any request whose Host isn't one we bound for.
Changes:
hermes_cli/web_server.py:
- New host_header_middleware runs before auth_middleware. Reads
app.state.bound_host (set by start_server) and rejects requests
whose Host header doesn't match the bound interface with HTTP 400.
- Loopback binds accept localhost / 127.0.0.1 / ::1. Non-loopback
binds require exact match. 0.0.0.0 binds skip the check (explicit
--insecure opt-in; no app-layer defence possible).
- IPv6 bracket notation parsed correctly: [::1] and [::1]:9119 both
accepted.
scripts/whatsapp-bridge/bridge.js:
- Express middleware rejects non-loopback Host headers. Bridge
already binds 127.0.0.1-only, this adds the complementary app-layer
check for DNS rebinding defence.
Tests: 8 new in tests/hermes_cli/test_web_server_host_header.py
covering loopback/non-loopback/zero-zero binds, IPv6 brackets, case
insensitivity, and end-to-end middleware rejection via TestClient.
Reported in GHSA-ppp5-vxwm-4cf7 by @bupt-Yy-young. Hardening — not
CVE per SECURITY.md §3. The dashboard's main trust boundary is the
loopback bind + session token; DNS rebinding defeats the bind assumption
but not the token (since the rebinding browser still sees a first-party
fetch to 127.0.0.1 with the token-gated API). Host-header validation
adds the missing belt-and-braces layer.
Two call sites still used a raw substring check to identify ollama.com:
hermes_cli/runtime_provider.py:496:
_is_ollama_url = "ollama.com" in base_url.lower()
run_agent.py:6127:
if fb_base_url_hint and "ollama.com" in fb_base_url_hint.lower() ...
Same bug class as GHSA-xf8p-v2cg-h7h5 (OpenRouter substring leak), which
was fixed in commit dbb7e00e via base_url_host_matches() across the
codebase. The earlier sweep missed these two Ollama sites. Self-discovered
during April 2026 security-advisory triage; filed as GHSA-76xc-57q6-vm5m.
Impact is narrow — requires a user with OLLAMA_API_KEY configured AND a
custom base_url whose path or look-alike host contains 'ollama.com'.
Users on default provider flows are unaffected. Filed as a draft advisory
to use the private-fork flow; not CVE-worthy on its own.
Fix is mechanical: replace substring check with base_url_host_matches
at both sites. Same helper the rest of the codebase uses.
Tests: 67 -> 71 passing. 7 new host-matcher cases in
tests/test_base_url_hostname.py (path injection, lookalike host,
localtest.me subdomain, ollama.ai TLD confusion, localhost, genuine
ollama.com, api.ollama.com subdomain) + 4 call-site tests in
tests/hermes_cli/test_runtime_provider_resolution.py verifying
OLLAMA_API_KEY is selected only when base_url actually targets
ollama.com.
Fixes GHSA-76xc-57q6-vm5m
Gateway /model <name> --provider opencode-go (or any provider whose /models
endpoint is down, 404s, or doesn't exist) silently failed. validate_requested_model
returned accepted=False whenever fetch_api_models returned None, switch_model
returned success=False, and the gateway never wrote _session_model_overrides —
so the switch appeared to succeed in the error message flow but the next turn
kept calling the old provider.
The validator already had static-catalog fallbacks for MiniMax and Codex
(providers without a /models endpoint). Extended the same pattern as the
terminal fallback: when the live probe fails, consult provider_model_ids()
for the curated catalog. Known models → accepted+recognized. Close typos →
auto-corrected. Unknown models → soft-accepted with a 'Not in curated
catalog' warning. Providers with no catalog at all → soft-accepted with a
generic 'Note:' warning, finally honoring the in-code comment ('Accept and
persist, but warn') that had been lying since it was written.
Tests: 7 new tests in test_opencode_go_validation_fallback.py covering the
catalog lookup, case-insensitive match, auto-correct, unknown-with-suggestion,
unknown-without-suggestion, and no-catalog paths. TestValidateApiFallback in
test_model_validation.py updated — its four 'rejected_when_api_down' tests
were encoding exactly the bug being fixed.
* feat(models): hide OpenRouter models that don't advertise tool support
Port from Kilo-Org/kilocode#9068.
hermes-agent is tool-calling-first — every provider path assumes the
model can invoke tools. Models whose OpenRouter supported_parameters
doesn't include 'tools' (e.g. image-only or completion-only models)
cannot be driven by the agent loop and fail at the first tool call.
Filter them out of fetch_openrouter_models() so they never appear in
the model picker (`hermes model`, setup wizard, /model slash command).
Permissive when the field is missing — OpenRouter-compatible gateways
(Nous Portal, private mirrors, older snapshots) don't always populate
supported_parameters. Treat missing as 'unknown → allow' rather than
silently emptying the picker on those gateways. Only hide models
whose supported_parameters is an explicit list that omits tools.
Tests cover: tools present → kept, tools absent → dropped, field
missing → kept, malformed non-list → kept, non-dict item → kept,
empty list → dropped.
* refactor(acp): validate method_id against advertised provider in authenticate()
Previously authenticate() accepted any method_id whenever the server had
provider credentials configured. This was not a vulnerability under the
personal-assistant trust model (ACP is stdio-only, local-trust — anything
that can reach the transport is already code-execution-equivalent to the
user), but it was sloppy API hygiene: the advertised auth_methods list
from initialize() was effectively ignored.
Now authenticate() only returns AuthenticateResponse when method_id
matches the currently-advertised provider (case-insensitive). Mismatched
or missing method_id returns None, consistent with the no-credentials
case.
Raised by xeloxa via GHSA-g5pf-8w9m-h72x. Declined as a CVE
(ACP transport is stdio, local-trust model), but the correctness fix is
worth having on its own.
OpenCode Go's published model list (opencode.ai/docs/go) includes kimi-k2.6,
qwen3.5-plus, and qwen3.6-plus, but Hermes' curated lists didn't carry them.
When the live /models probe fails during `hermes model`, users fell back to
the stale curated list and had to type newer models via 'Enter custom model
name'.
Adds kimi-k2.6 (now first in the Go list), qwen3.6-plus, and qwen3.5-plus
to both the model picker (hermes_cli/models.py) and setup defaults
(hermes_cli/setup.py). All routed through the existing opencode-go
chat_completions path — no api_mode changes needed.
Every credential source Hermes reads from now behaves identically on
`hermes auth remove`: the pool entry stays gone across fresh load_pool()
calls, even when the underlying external state (env var, OAuth file,
auth.json block, config entry) is still present.
Before this, auth_remove_command was a 110-line if/elif with five
special cases, and three more sources (qwen-cli, copilot, custom
config) had no removal handler at all — their pool entries silently
resurrected on the next invocation. Even the handled cases diverged:
codex suppressed, anthropic deleted-without-suppressing, nous cleared
without suppressing. Each new provider added a new gap.
What's new:
agent/credential_sources.py — RemovalStep registry, one entry per
source (env, claude_code, hermes_pkce, nous device_code, codex
device_code, qwen-cli, copilot gh_cli + env vars, custom config).
auth_remove_command dispatches uniformly via find_removal_step().
Changes elsewhere:
agent/credential_pool.py — every upsert in _seed_from_env,
_seed_from_singletons, and _seed_custom_pool now gates on
is_source_suppressed(provider, source) via a shared helper.
hermes_cli/auth_commands.py — auth_remove_command reduced to 25
lines of dispatch; auth_add_command now clears ALL suppressions for
the provider on re-add (was env:* only).
Copilot is special: the same token is seeded twice (gh_cli via
_seed_from_singletons + env:<VAR> via _seed_from_env), so removing one
entry without suppressing the other variants lets the duplicate
resurrect. The copilot RemovalStep suppresses gh_cli + all three env
variants (COPILOT_GITHUB_TOKEN, GH_TOKEN, GITHUB_TOKEN) at once.
Tests: 11 new unit tests + 4059 existing pass. 12 E2E scenarios cover
every source in isolated HERMES_HOME with simulated fresh processes.
Removing an env-seeded credential only cleared ~/.hermes/.env and the
current process's os.environ, leaving shell-exported vars (shell profile,
systemd EnvironmentFile, launchd plist) to resurrect the entry on the
next load_pool() call. This matched the pre-#11485 codex behaviour.
Now we suppress env:<VAR> in auth.json on remove, gate _seed_from_env()
behind is_source_suppressed(), clear env:* suppressions on auth add,
and print a diagnostic pointing at the shell when the var lives there.
Applies to every env:* seeded credential (xai, deepseek, moonshot, zai,
nvidia, openrouter, anthropic, etc.), not just xai.
Reported by @teknium1 from community user 'Artificial Brain' — couldn't
remove their xAI key via hermes auth remove.
Catalog snapshots, config version literals, and enumeration counts are data
that changes as designed. Tests that assert on those values add no
behavioral coverage — they just break CI on every routine update and cost
engineering time to 'fix.'
Replace with invariants where one exists, delete where none does.
Deleted (pure snapshots):
- TestMinimaxModelCatalog (3 tests): 'MiniMax-M2.7 in models' et al
- TestGeminiModelCatalog: 'gemini-2.5-pro in models', 'gemini-3.x in models'
- test_browser_camofox_state::test_config_version_matches_current_schema
(docstring literally said it would break on unrelated bumps)
Relaxed (keep plumbing check, drop snapshot):
- Xiaomi / Arcee / Kimi moonshot / Kimi coding / HuggingFace static lists:
now assert 'provider exists and has >= 1 entry' instead of specific names
- HuggingFace main/models.py consistency test: drop 'len >= 6' floor
Dynamicized (follow source, not a literal):
- 3x test_config.py migration tests: raw['_config_version'] ==
DEFAULT_CONFIG['_config_version'] instead of hardcoded 21
Fixed stale tests against intentional behavior changes:
- test_insights::test_gateway_format_hides_cost: name matches new behavior
(no dollar figures); remove contradicting '$' in text assertion
- test_config::prefers_api_then_url_then_base_url: flipped per PR #9332;
rename + update to base_url > url > api
- test_anthropic_adapter: relax assert_called_once() (xdist-flaky) to
assert called — contract is 'credential flowed through'
- test_interrupt_propagation: add provider/model/_base_url to bare-agent
fixture so the stale-timeout code path resolves
Fixed stale integration tests against opt-in plugin gate:
- transform_tool_result + transform_terminal_output: write plugins.enabled
allow-list to config.yaml and reset the plugin manager singleton
Source fix (real consistency invariant):
- agent/model_metadata.py: add moonshotai/Kimi-K2.6 context length
(262144, same as K2.5). test_model_metadata_has_context_lengths was
correctly catching the gap.
Policy:
- AGENTS.md Testing section: new subsection 'Don't write change-detector
tests' with do/don't examples. Reviewers should reject catalog-snapshot
assertions in new tests.
Covers every test that failed on the last completed main CI run
(24703345583) except test_modal_sandbox_fixes::test_terminal_tool_present
+ test_terminal_and_file_toolsets_resolve_all_tools, which now pass both
alone and with the full tests/tools/ directory (xdist ordering flake that
resolved itself).
Delete the stale literal `_PROVIDER_MODELS["ai-gateway"]` (gpt-5,
gemini-2.5-pro, claude-4.5 — outdated the moment PR #13223 landed with
its curated `AI_GATEWAY_MODELS` snapshot) and derive it from
`AI_GATEWAY_MODELS` instead, so the picker tuples and the bare-id
fallback catalog stay in sync automatically. Also fixes
`get_default_model_for_provider('ai-gateway')` to return kimi-k2.6
(the curated recommendation) instead of claude-opus-4.6.
Aslaaen's fix in the original PR covered _detect_api_mode_for_url and the
two openai/xai sites in run_agent.py. This finishes the sweep: the same
substring-match false-positive class (e.g. https://api.openai.com.evil/v1,
https://proxy/api.openai.com/v1, https://api.anthropic.com.example/v1)
existed in eight more call sites, and the hostname helper was duplicated
in two modules.
- utils: add shared base_url_hostname() (single source of truth).
- hermes_cli/runtime_provider, run_agent: drop local duplicates, import
from utils. Reuse the cached AIAgent._base_url_hostname attribute
everywhere it's already populated.
- agent/auxiliary_client: switch codex-wrap auto-detect, max_completion_tokens
gate (auxiliary_max_tokens_param), and custom-endpoint max_tokens kwarg
selection to hostname equality.
- run_agent: native-anthropic check in the Claude-style model branch
and in the AIAgent init provider-auto-detect branch.
- agent/model_metadata: Anthropic /v1/models context-length lookup.
- hermes_cli/providers.determine_api_mode: anthropic / openai URL
heuristics for custom/unknown providers (the /anthropic path-suffix
convention for third-party gateways is preserved).
- tools/delegate_tool: anthropic detection for delegated subagent
runtimes.
- hermes_cli/setup, hermes_cli/tools_config: setup-wizard vision-endpoint
native-OpenAI detection (paired with deduping the repeated check into
a single is_native_openai boolean per branch).
Tests:
- tests/test_base_url_hostname.py covers the helper directly
(path-containing-host, host-suffix, trailing dot, port, case).
- tests/hermes_cli/test_determine_api_mode_hostname.py adds the same
regression class for determine_api_mode, plus a test that the
/anthropic third-party gateway convention still wins.

Load-time sanitizer silently removed non-ASCII codepoints from any
env var ending in _API_KEY / _TOKEN / _SECRET / _KEY, turning
copy-paste artifacts (Unicode lookalikes, ZWSP, NBSP) into opaque
provider-side API_KEY_INVALID errors.
Warn once per key to stderr with the offending codepoints (U+XXXX)
and guidance to re-copy from the provider dashboard.
When the live Vercel AI Gateway catalog exposes a Moonshot model with
zero input AND output pricing, it's promoted to position #1 as the
recommended default — even if the exact ID isn't in the curated
AI_GATEWAY_MODELS list. This enables dynamic discovery of new free
Moonshot variants without requiring a PR to update curation.
Paid Moonshot models are unaffected; falls back to the normal curated
recommended tag when no free Moonshot is live.
- Curated AI_GATEWAY_MODELS list in hermes_cli/models.py (OSS first,
kimi-k2.5 as recommended default).
- fetch_ai_gateway_models() filters the curated list against the live
/v1/models catalog; falls back to the snapshot on network failure.
- fetch_ai_gateway_pricing() translates Vercel's input/output field
names to the prompt/completion shape the shared picker expects;
carries input_cache_read / input_cache_write through unchanged.
- get_pricing_for_provider() now handles ai-gateway.
- _model_flow_ai_gateway() provides a guided URL prompt when no key
is set and a pricing-column picker; routes ai-gateway to it instead
of the generic api-key flow.
Users can declare shell scripts in config.yaml under a hooks: block that
fire on plugin-hook events (pre_tool_call, post_tool_call, pre_llm_call,
subagent_stop, etc). Scripts receive JSON on stdin, can return JSON on
stdout to block tool calls or inject context pre-LLM.
Key design:
- Registers closures on existing PluginManager._hooks dict — zero changes
to invoke_hook() call sites
- subprocess.run(shell=False) via shlex.split — no shell injection
- First-use consent per (event, command) pair, persisted to allowlist JSON
- Bypass via --accept-hooks, HERMES_ACCEPT_HOOKS=1, or hooks_auto_accept
- hermes hooks list/test/revoke/doctor CLI subcommands
- Adds subagent_stop hook event fired after delegate_task children exit
- Claude Code compatible response shapes accepted

The opt-in-by-default change (70111eea) requires plugins to be listed
in plugins.enabled. The cherry-picked test fixtures didn't write this
config, so two tests failed on current main.

Custom Claude proxies fronted by Cloudflare with Browser Integrity Check
enabled (e.g. `packyapi.com`) reject requests with the default
`Python-urllib/*` signature, returning HTTP 403 "error code: 1010".
`probe_api_models` swallowed that in its blanket `except Exception:
continue`, so `validate_requested_model` returned the misleading
"Could not reach the <provider> API to validate `<model>`" error even
though the endpoint is reachable and lists the requested model.
Advertise the probe request as `hermes-cli/<version>` so Cloudflare
treats it as a first-party client. This mirrors the pattern already used
by `agent/gemini_native_adapter.py` and `agent/anthropic_adapter.py`,
which set a descriptive UA for the same reason.
Reproduction (pre-fix):
python3 -c "
import urllib.request
req = urllib.request.Request(
'https://www.packyapi.com/v1/models',
headers={'Authorization': 'Bearer sk-...'})
urllib.request.urlopen(req).read()
"
urllib.error.HTTPError: HTTP Error 403: Forbidden
(body: b'error code: 1010')
Any non-urllib UA (Mozilla, curl, reqwest) returns 200 with the
OpenAI-compatible models listing.
Tested on macOS (Python 3.11). No cross-platform concerns — the change
is a single header addition to an existing `urllib.request.Request`.

Closes#9332
Plugins now require explicit consent to load. Discovery still finds every
plugin — user-installed, bundled, and pip — so they all show up in
`hermes plugins` and `/plugins`, but the loader only instantiates
plugins whose name appears in `plugins.enabled` in config.yaml. This
removes the previous ambient-execution risk where a newly-installed or
bundled plugin could register hooks, tools, and commands on first run
without the user opting in.
The three-state model is now explicit:
enabled — in plugins.enabled, loads on next session
disabled — in plugins.disabled, never loads (wins over enabled)
not enabled — discovered but never opted in (default for new installs)
`hermes plugins install <repo>` prompts "Enable 'name' now? [y/N]"
(defaults to no). New `--enable` / `--no-enable` flags skip the prompt
for scripted installs. `hermes plugins enable/disable` manage both lists
so a disabled plugin stays explicitly off even if something later adds
it to enabled.
Config migration (schema v20 → v21): existing user plugins already
installed under ~/.hermes/plugins/ (minus anything in plugins.disabled)
are auto-grandfathered into plugins.enabled so upgrades don't silently
break working setups. Bundled plugins are NOT grandfathered — even
existing users have to opt in explicitly.
Also: HERMES_DISABLE_BUNDLED_PLUGINS env var removed (redundant with
opt-in default), cmd_list now shows bundled + user plugins together with
their three-state status, interactive UI tags bundled entries
[bundled], docs updated across plugins.md and built-in-plugins.md.
Validation: 442 plugin/config tests pass. E2E: fresh install discovers
disk-cleanup but does not load it; `hermes plugins enable disk-cleanup`
activates hooks; migration grandfathers existing user plugins correctly
while leaving bundled plugins off.
Closes#8933 more fully, extending the per-tool transform_terminal_output
hook from #12929 to a generic seam that fires after every tool dispatch.
Plugins can rewrite any tool's result string (normalize formats, redact
fields, summarize verbose output) without wrapping individual tools.
Changes
- hermes_cli/plugins.py: add "transform_tool_result" to VALID_HOOKS
- model_tools.py: invoke the hook in handle_function_call after
post_tool_call (which remains observational); first valid str return
replaces the result; fail-open
- tests/test_transform_tool_result_hook.py: 9 new tests covering no-op,
None return, non-string return, first-match wins, kwargs, hook
exception fallback, post_tool_call observation invariant, ordering
vs post_tool_call, and an end-to-end real-plugin integration
- tests/hermes_cli/test_plugins.py: assert new hook in VALID_HOOKS
- tests/test_model_tools.py: extend the hook-call-sequence assertion
to include the new hook
Design
- transform_tool_result runs AFTER post_tool_call so observers always
see the original (untransformed) result. This keeps post_tool_call's
observational contract.
- transform_terminal_output (from #12929) still runs earlier, inside
terminal_tool, so plugins can canonicalize BEFORE the 50k truncation
drops middle content. Both hooks coexist; they target different layers.
