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).
Add agent/transports/types.py with three shared dataclasses:
- NormalizedResponse: content, tool_calls, finish_reason, reasoning, usage, provider_data
- ToolCall: id, name, arguments, provider_data (per-tool-call protocol metadata)
- Usage: prompt_tokens, completion_tokens, total_tokens, cached_tokens
Add normalize_anthropic_response_v2() to anthropic_adapter.py — wraps the
existing v1 function and maps its output to NormalizedResponse. One call site
in run_agent.py (the main normalize branch) uses v2 with a back-compat shim
to SimpleNamespace for downstream code.
No ABC, no registry, no streaming, no client lifecycle. Those land in PR 3
with the first concrete transport (AnthropicTransport).
46 new tests:
- test_types.py: dataclass construction, build_tool_call, map_finish_reason
- test_anthropic_normalize_v2.py: v1-vs-v2 regression tests (text, tools,
thinking, mixed, stop reasons, mcp prefix stripping, edge cases)
Part of the provider transport refactor (PR 2 of 9).
Classic-CLI /steer typed during an active agent run was queued through
self._pending_input alongside ordinary user input. process_loop, which
drains that queue, is blocked inside self.chat() for the entire run,
so the queued command was not pulled until AFTER _agent_running had
flipped back to False — at which point process_command() took the idle
fallback ("No agent running; queued as next turn") and delivered the
steer as an ordinary next-turn user message.
From Utku's bug report on PR #13205: mid-run /steer arrived minutes
later at the end of the turn as a /queue-style message, completely
defeating its purpose.
Fix: add _should_handle_steer_command_inline() gating — when
_agent_running is True and the user typed /steer, dispatch
process_command(text) directly from the prompt_toolkit Enter handler
on the UI thread instead of queueing. This mirrors the existing
_should_handle_model_command_inline() pattern for /model and is
safe because agent.steer() is thread-safe (uses _pending_steer_lock,
no prompt_toolkit state mutation, instant return).
No changes to the idle-path behavior: /steer typed with no active
agent still takes the normal queue-and-drain route so the fallback
"No agent running; queued as next turn" message is preserved.
Validation:
- 7 new unit tests in tests/cli/test_cli_steer_busy_path.py covering
the detector, dispatch path, and idle-path control behavior.
- All 21 existing tests in tests/run_agent/test_steer.py still pass.
- Live PTY end-to-end test with real agent + real openrouter model:
22:36:22 API call #1 (model requested execute_code)
22:36:26 ENTER FIRED: agent_running=True, text='/steer ...'
22:36:26 INLINE STEER DISPATCH fired
22:36:43 agent.log: 'Delivered /steer to agent after tool batch'
22:36:44 API call #2 included the steer; response contained marker
Same test on the tip of main without this fix shows the steer
landing as a new user turn ~20s after the run ended.
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.
The mid-run steer marker was '[USER STEER (injected mid-run, not tool
output): <text>]'. Replaced with a plain two-newline-prefixed
'User guidance: <text>' suffix.
Rationale: the marker lives inside the tool result's content string
regardless of whether the tool returned JSON, plain text, an MCP
result, or a plugin result. The bracketed tag read like structured
metadata that some tools (terminal, execute_code) could confuse with
their own output formatting. A plain labelled suffix works uniformly
across every content shape we produce.
Behavior unchanged:
- Still injected into the last tool-role message's content.
- Still preserves multimodal (Anthropic) content-block lists by
appending a text block.
- Still drained at both sites added in #12959 and #13205 — per-tool
drain between individual calls, and pre-API-call drain at the top
of each main-loop iteration.
Checked Codex's equivalent (pending_input / inject_user_message_without_turn
in codex-rs/core): they record mid-turn user input as a real role:user
message via record_user_prompt_and_emit_turn_item(). That's cleaner for
their Responses-API model but not portable to Chat Completions where
role alternation after tool_calls is strict. Embedding the guidance in
the last tool result remains the correct placement for us.
Validation: all 21 tests in tests/run_agent/test_steer.py pass.
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.
Requests through Vercel AI Gateway now carry referrerUrl / appName /
User-Agent attribution so traffic shows up in the gateway's analytics.
Adds _AI_GATEWAY_HEADERS in auxiliary_client and a new
ai-gateway.vercel.sh branch in _apply_client_headers_for_base_url.
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

Pass the user's configured api_key through local-server detection and
context-length probes (detect_local_server_type, _query_local_context_length,
query_ollama_num_ctx) and use LM Studio's native /api/v1/models endpoint in
fetch_endpoint_model_metadata when a loaded instance is present — so the
probed context length is the actual runtime value the user loaded the model
at, not just the model's theoretical max.
Helps local-LLM users whose auto-detected context length was wrong, causing
compression failures and context-overrun crashes.
When /steer is sent during an API call (model thinking), the steer text
sits in _pending_steer until after the next tool batch — which may never
come if the model returns a final response. In that case the steer is
only delivered as a post-run follow-up, defeating the purpose.
Add a pre-API-call drain at the top of the main loop: before building
api_messages, check _pending_steer and inject into the last tool result
in the messages list. This ensures steers sent during model thinking are
visible on the very next API call.
If no tool result exists yet (first iteration), the steer is restashed
for the post-tool drain to pick up — injecting into a user message would
break role alternation.
Three new tests cover the pre-API-call drain: injection into last tool
result, restash when no tool message exists, and backward scan past
non-tool messages.

Adds native media attachment delivery to Signal via signal-cli JSON-RPC
attachments param. Signal messages with media now follow the same
early-return pattern as Telegram/Discord/Matrix — attachments are sent
only with the last chunk to avoid duplicates.
Follow-up fixes on top of the original PR:
- Moved Signal into its own early-return block above the restriction
check (matches Telegram/Discord/Matrix pattern)
- Fixed media_files being sent on every chunk in the generic loop
- Restored restriction/warning guards to simple form (Signal exits early)
- Fixed non-hermetic test writing to /tmp instead of tmp_path
Kimi's gateway selects the correct temperature server-side based on the
active mode (thinking -> 1.0, non-thinking -> 0.6). Sending any
temperature value — even the previously "correct" one — conflicts with
gateway-managed defaults.
Replaces the old approach of forcing specific temperature values (0.6
for non-thinking, 1.0 for thinking) with an OMIT_TEMPERATURE sentinel
that tells all call sites to strip the temperature key from API kwargs
entirely.
Changes:
- agent/auxiliary_client.py: OMIT_TEMPERATURE sentinel, _is_kimi_model()
prefix check (covers all kimi-* models), _fixed_temperature_for_model()
returns sentinel for kimi models. _build_call_kwargs() strips temp.
- run_agent.py: _build_api_kwargs, flush_memories, and summary generation
paths all handle the sentinel by popping/omitting temperature.
- trajectory_compressor.py: _effective_temperature_for_model returns None
for kimi (sentinel mapped), direct client calls use kwargs dict to
conditionally include temperature.
- mini_swe_runner.py: same sentinel handling via wrapper function.
- 6 test files updated: all 'forces temperature X' assertions replaced
with 'temperature not in kwargs' assertions.
Net: -76 lines (171 added, 247 removed).

Dropped the run.py group auth bypass (would have skipped user auth
for ALL platforms, not just WhatsApp).
Replaces the serial for-loop in tick() with ThreadPoolExecutor so all
jobs due in a single tick run concurrently. A slow job no longer blocks
others from executing, fixing silent job skipping (issue #9086).
Thread safety:
- Session/delivery env vars migrated from os.environ to ContextVars
(gateway/session_context.py) so parallel jobs can't clobber each
other's delivery targets. Each thread gets its own copied context.
- jobs.json read-modify-write cycles (advance_next_run, mark_job_run)
protected by threading.Lock to prevent concurrent save clobber.
- send_message_tool reads delivery vars via get_session_env() for
ContextVar-aware resolution with os.environ fallback.
Configuration:
- cron.max_parallel_jobs in config.yaml (null = unbounded, 1 = serial)
- HERMES_CRON_MAX_PARALLEL env var override

* feat(security): URL query param + userinfo + form body redaction
Port from nearai/ironclaw#2529.
Hermes already has broad value-shape coverage in agent/redact.py
(30+ vendor prefixes, JWTs, DB connstrs, etc.) but missed three
key-name-based patterns that catch opaque tokens without recognizable
prefixes:
1. URL query params - OAuth callback codes (?code=...),
access_token, refresh_token, signature, etc. These are opaque and
won't match any prefix regex. Now redacted by parameter NAME.
2. URL userinfo (https://user:pass@host) - for non-DB schemes. DB
schemes were already handled by _DB_CONNSTR_RE.
3. Form-urlencoded body (k=v pairs joined by ampersands) -
conservative, only triggers on clean pure-form inputs with no
other text.
Sensitive key allowlist matches ironclaw's (exact case-insensitive,
NOT substring - so token_count and session_id pass through).
Tests: +20 new test cases across 3 test classes. All 75 redact tests
pass; gateway/test_pii_redaction and tools/test_browser_secret_exfil
also green.
Known pre-existing limitation: _ENV_ASSIGN_RE greedy match swallows
whole all-caps ENV-style names + trailing text when followed by
another assignment. Left untouched here (out of scope); URL query
redaction handles the lowercase case.
* feat: replace kimi-k2.5 with kimi-k2.6 on OpenRouter and Nous Portal
Update model catalogs for OpenRouter (fallback snapshot), Nous Portal,
and NVIDIA NIM to reference moonshotai/kimi-k2.6. Add kimi-k2.6 to
the fixed-temperature frozenset in auxiliary_client.py so the 0.6
contract is enforced on aggregator routings.
Native Moonshot provider lists (kimi-coding, kimi-coding-cn, moonshot,
opencode-zen, opencode-go) are unchanged — those use Moonshot's own
model IDs which are unaffected.

The setup wizard could leave stt.model: "whisper-1" in config.yaml.
When using the local faster-whisper provider, this crashed with
"Invalid model size 'whisper-1'". Voice messages were silently ignored.
_normalize_local_model() now detects cloud-only names (whisper-1,
gpt-4o-transcribe, etc.) and maps them to the default local model
with a warning. Valid local sizes (tiny, base, small, medium, large-v3)
pass through unchanged.

Reasoning models (GLM-5.1, QwQ, DeepSeek R1) inflate completion_tokens

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`.

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.
The original name was cute but non-obvious; disk-cleanup says what it
does. Plugin directory, script, state path, log lines, slash command,
and test module all renamed. No user-visible state exists yet, so no
migration path is needed.
New website page "Built-in Plugins" documents the <repo>/plugins/<name>/
source, how discovery interacts with user/project plugins, the
HERMES_DISABLE_BUNDLED_PLUGINS escape hatch, disk-cleanup's hook
behaviour and deletion rules, and guidance on when a plugin belongs
bundled vs. user-installable. Added to the Features → Core sidebar next
to the main Plugins page, with a cross-reference from plugins.md.
Rewires @LVT382009's disk-guardian (PR #12212) from a skill-plus-script
into a plugin that runs entirely via hooks — no agent compliance needed.
- post_tool_call hook auto-tracks files created by write_file / terminal
/ patch when they match test_/tmp_/*.test.* patterns under HERMES_HOME
- on_session_end hook runs cmd_quick cleanup when test files were
auto-tracked during the turn; stays quiet otherwise
- /disk-guardian slash command keeps status / dry-run / quick / deep /
track / forget for manual use
- Deterministic cleanup rules, path safety, atomic writes, and audit
logging preserved from the original contribution
- Protect well-known top-level state dirs (logs/, memories/, sessions/,
cron/, cache/, etc.) from empty-dir removal so fresh installs don't
get gutted on first session end
The plugin system gains a bundled-plugin discovery path (<repo>/plugins/
<name>/) alongside user/project/entry-point sources. Memory and
context_engine subdirs are skipped — they keep their own discovery
paths. HERMES_DISABLE_BUNDLED_PLUGINS=1 suppresses the scan; the test
conftest sets it by default so existing plugin tests stay clean.

OpenAI-compatible clients (Open WebUI, LobeChat, etc.) can now send vision
requests to the API server. Both endpoints accept the canonical OpenAI
multimodal shape:
Chat Completions: {type: text|image_url, image_url: {url, detail?}}
Responses: {type: input_text|input_image, image_url: <str>, detail?}
The server validates and converts both into a single internal shape that the
existing agent pipeline already handles (Anthropic adapter converts,
OpenAI-wire providers pass through). Remote http(s) URLs and data:image/*
URLs are supported.
Uploaded files (file, input_file, file_id) and non-image data: URLs are
rejected with 400 unsupported_content_type.
Changes:
- gateway/platforms/api_server.py
- _normalize_multimodal_content(): validates + normalizes both Chat and
Responses content shapes. Returns a plain string for text-only content
(preserves prompt-cache behavior on existing callers) or a canonical
[{type:text|image_url,...}] list when images are present.
- _content_has_visible_payload(): replaces the bare truthy check so a
user turn with only an image no longer rejects as 'No user message'.
- _handle_chat_completions and _handle_responses both call the new helper
for user/assistant content; system messages continue to flatten to text.
- Codex conversation_history, input[], and inline history paths all share
the same validator. No duplicated normalizers.
- run_agent.py
- _summarize_user_message_for_log(): produces a short string summary
('[1 image] describe this') from list content for logging, spinner
previews, and trajectory writes. Fixes AttributeError when list
user_message hit user_message[:80] + '...' / .replace().
- _chat_content_to_responses_parts(): module-level helper that converts
chat-style multimodal content to Responses 'input_text'/'input_image'
parts. Used in _chat_messages_to_responses_input for Codex routing.
- _preflight_codex_input_items() now validates and passes through list
content parts for user/assistant messages instead of stringifying.
- tests/gateway/test_api_server_multimodal.py (new, 38 tests)
- Unit coverage for _normalize_multimodal_content, including both part
formats, data URL gating, and all reject paths.
- Real aiohttp HTTP integration on /v1/chat/completions and /v1/responses
verifying multimodal payloads reach _run_agent intact.
- 400 coverage for file / input_file / non-image data URL.
- tests/run_agent/test_run_agent_multimodal_prologue.py (new)
- Regression coverage for the prologue no-crash contract.

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.
SessionStore.prune_old_entries was calling
self._has_active_processes_fn(entry.session_id) but the callback wired
up in gateway/run.py is process_registry.has_active_for_session, which
compares against session_key, not session_id. Every other caller in
session.py (_is_session_expired, _should_reset) already passes
session_key, so prune was the only outlier — and because session_id and
session_key live in different namespaces, the guard never fired.
Result in production: sessions with live background processes (queued
cron output, detached agents, long-running Bash) were pruned out of
_entries despite the docstring promising they'd be preserved. When the
process finished and tried to deliver output, the session_key to
session_id mapping was gone and the work was effectively orphaned.
Also update the existing test_prune_skips_entries_with_active_processes,
which was checking the wrong interface (its mock callback took session_id
so it agreed with the buggy implementation). The test now uses a
session_key-based mock, matching the production callback's real contract,
and a new regression guard test pins the behaviour.
Swallowed exceptions inside the prune loop now log at debug level instead
of silently disappearing.
After a conversation gets compressed, run_agent's _compress_context ends
the parent session and creates a continuation child with the same logical
conversation. Every list affordance in the codebase (list_sessions_rich
with its default include_children=False, plus the CLI/TUI/gateway/ACP
surfaces on top of it) hid those children, and resume-by-ID on the old
root landed on a dead parent with no messages.
Fix: lineage-aware projection on the read path.
- hermes_state.py::get_compression_tip(session_id) — walk the chain
forward using parent.end_reason='compression' AND
child.started_at >= parent.ended_at. The timing guard separates
compression continuations from delegate subagents (which were created
while the parent was still live) without needing a schema migration.
- hermes_state.py::list_sessions_rich — new project_compression_tips
flag (default True). For each compressed root in the result, replace
surfaced fields (id, ended_at, end_reason, message_count,
tool_call_count, title, last_active, preview, model, system_prompt)
with the tip's values. Preserve the root's started_at so chronological
ordering stays stable. Projected rows carry _lineage_root_id for
downstream consumers. Pass False to get raw roots (admin/debug).
- hermes_cli/main.py::_resolve_session_by_name_or_id — project forward
after ID/title resolution, so users who remember an old root ID (from
notes, or from exit summaries produced before the sibling Bug 1 fix)
land on the live tip.
All downstream callers of list_sessions_rich benefit automatically:
- cli.py _list_recent_sessions (/resume, show_history affordance)
- hermes_cli/main.py sessions list / sessions browse
- tui_gateway session.list picker
- gateway/run.py /resume titled session listing
- tools/session_search_tool.py
- acp_adapter/session.py
Tests: 7 new in TestCompressionChainProjection covering full-chain walks,
delegate-child exclusion, tip surfacing with lineage tracking, raw-root
mode, chronological ordering, and broken-chain graceful fallback.
Verified live: ran a real _compress_context on a live Gemini-backed
session, confirmed the DB split, then verified
- db.list_sessions_rich surfaces tip with _lineage_root_id set
- hermes sessions list shows the tip, not the ended parent
- _resolve_session_by_name_or_id(old_root_id) -> tip_id
- _resolve_last_session -> tip_id
Addresses #10373.
On macOS, Unix domain socket paths are capped at 104 bytes (sun_path).
SSH appends a 16-byte random suffix to the ControlPath when operating
in ControlMaster mode. With an IPv6 host embedded literally in the
filename and a deeply-nested macOS $TMPDIR like
/var/folders/XX/YYYYYYYYYYYY/T/, the full path reliably exceeds the
limit — every terminal/file-op tool call then fails immediately with
``unix_listener: path "…" too long for Unix domain socket``.
Swap the ``user@host:port.sock`` filename for a sha256-derived 16-char
hex digest. The digest is deterministic for a given (user, host, port)
triple, so ControlMaster reuse across reconnects is preserved, and the
full path fits comfortably under the limit even after SSH's random
suffix. Collision space is 2^64 — effectively unreachable for the
handful of concurrent connections any single Hermes process holds.
Regression tests cover: path length under realistic macOS $TMPDIR with
the IPv6 host from the issue report, determinism for reconnects, and
distinctness across different (user, host, port) triples.
Closes#11840
