07927f6bf2 feat(stt): add free local whisper transcription via faster-whisper (#1185)
* fix: Home Assistant event filtering now closed by default

Previously, when no watch_domains or watch_entities were configured,
ALL state_changed events passed through to the agent, causing users
to be flooded with notifications for every HA entity change.

Now events are dropped by default unless the user explicitly configures:
- watch_domains: list of domains to monitor (e.g. climate, light)
- watch_entities: list of specific entity IDs to monitor
- watch_all: true (new option — opt-in to receive all events)

A warning is logged at connect time if no filters are configured,
guiding users to set up their HA platform config.

All 49 gateway HA tests + 52 HA tool tests pass.

* docs: update Home Assistant integration documentation

- homeassistant.md: Fix event filtering docs to reflect closed-by-default
  behavior. Add watch_all option. Replace Python dict config example with
  YAML. Fix defaults table (was incorrectly showing 'all'). Add required
  configuration warning admonition.
- environment-variables.md: Add HASS_TOKEN and HASS_URL to Messaging section.
- messaging/index.md: Add Home Assistant to description, architecture
  diagram, platform toolsets table, and Next Steps links.

* fix(terminal): strip provider env vars from background and PTY subprocesses

Extends the env var blocklist from #1157 to also cover the two remaining
leaky paths in process_registry.py:

- spawn_local() PTY path (line 156)
- spawn_local() background Popen path (line 197)

Both were still using raw os.environ, leaking provider vars to background
processes and interactive PTY sessions. Now uses the same dynamic
_HERMES_PROVIDER_ENV_BLOCKLIST from local.py.

Explicit env_vars passed to spawn_local() still override the blocklist,
matching the existing behavior for callers that intentionally need these.

Gap identified by PR #1004 (@PeterFile).

* feat(delegate): add observability metadata to subagent results

Enrich delegate_task results with metadata from the child AIAgent:

- model: which model the child used
- exit_reason: completed | interrupted | max_iterations
- tokens.input / tokens.output: token counts
- tool_trace: per-tool-call trace with byte sizes and ok/error status

Tool trace uses tool_call_id matching to correctly pair parallel tool
calls with their results, with a fallback for messages without IDs.

Cherry-picked from PR #872 by @omerkaz, with fixes:
- Fixed parallel tool call trace pairing (was always updating last entry)
- Removed redundant 'iterations' field (identical to existing 'api_calls')
- Added test for parallel tool call trace correctness

* feat(stt): add free local whisper transcription via faster-whisper

Replace OpenAI-only STT with a dual-provider system mirroring the TTS
architecture (Edge TTS free / ElevenLabs paid):

  STT: faster-whisper local (free, default) / OpenAI Whisper API (paid)

Changes:
- tools/transcription_tools.py: Full rewrite with provider dispatch,
  config loading, local faster-whisper backend, and OpenAI API backend.
  Auto-downloads model (~150MB for 'base') on first voice message.
  Singleton model instance reused across calls.
- pyproject.toml: Add faster-whisper>=1.0.0 as core dependency
- hermes_cli/config.py: Expand stt config to match TTS pattern with
  provider selection and per-provider model settings
- agent/context_compressor.py: Fix .strip() crash when LLM returns
  non-string content (dict from llama.cpp, None). Fixes #1100 partially.
- tests/: 23 new tests for STT providers + 2 for compressor fix
- docs/: Updated Voice & TTS page with STT provider table, model sizes,
  config examples, and fallback behavior

Fallback behavior:
- Local not installed → OpenAI API (if key set)
- OpenAI key not set → local whisper (if installed)
- Neither → graceful error message to user

c92507e53d fix(terminal): strip Hermes provider env vars from subprocess environment (#1157)
Terminal subprocesses inherit OPENAI_BASE_URL and other provider env
vars loaded from ~/.hermes/.env, silently misrouting external CLIs
like codex.  Build a blocklist dynamically from the provider registry
so new providers are automatically covered.  Callers that truly need
a blocked var can opt in via the _HERMES_FORCE_ prefix.

Closes #1002

06a5cc484c fix: improve gateway secret capture guidance message

ccfbf42844 feat: secure skill env setup on load (core #688)
When a skill declares required_environment_variables in its YAML
frontmatter, missing env vars trigger a secure TUI prompt (identical
to the sudo password widget) when the skill is loaded. Secrets flow
directly to ~/.hermes/.env, never entering LLM context.

Key changes:
- New required_environment_variables frontmatter field for skills
- Secure TUI widget (masked input, 120s timeout)
- Gateway safety: messaging platforms show local setup guidance
- Legacy prerequisites.env_vars normalized into new format
- Remote backend handling: conservative setup_needed=True
- Env var name validation, file permissions hardened to 0o600
- Redact patterns extended for secret-related JSON fields
- 12 existing skills updated with prerequisites declarations
- ~48 new tests covering skip, timeout, gateway, remote backends
- Dynamic panel widget sizing (fixes hardcoded width from original PR)

Cherry-picked from PR #723 by kshitijk4poor, rebased onto current main
with conflict resolution.

Fixes #688

5d0d5b191c feat: concurrent tool execution with ThreadPoolExecutor
When the model returns multiple tool calls in a single response, they are
now executed concurrently using a thread pool instead of sequentially.
This significantly reduces wall-clock time when multiple independent tools
are batched (e.g. parallel web_search, read_file, terminal calls).

Architecture:
- _execute_tool_calls() dispatches to sequential or concurrent path
- Single tool calls and batches containing 'clarify' use sequential path
- Multiple non-interactive tools use ThreadPoolExecutor (max 8 workers)
- Results are collected and appended to messages in original order
- _invoke_tool() extracted as shared tool invocation helper

Safety:
- Pre-flight interrupt check skips all tools if interrupted
- Per-tool exception handling: one failure doesn't crash the batch
- Result truncation (100k char limit) applied per tool
- Budget pressure injection after all tools complete
- Checkpoints taken before file-mutating tools
- CLI spinner shows batch progress, then per-tool completion messages

Tests: 10 new tests covering dispatch logic, ordering, error handling,
interrupt behavior, truncation, and _invoke_tool routing.

2a62514d17 feat: add 'View full command' option to dangerous command approval (#887)
When a dangerous command is detected and the user is prompted for
approval, long commands are truncated (80 chars in fallback, 70 chars
in the TUI). Users had no way to see the full command before deciding.

This adds a 'View full command' option across all approval interfaces:

- CLI fallback (tools/approval.py): [v]iew option in the prompt menu.
  Shows the full command and re-prompts for approval decision.
- CLI TUI (cli.py): 'Show full command' choice in the arrow-key
  selection panel. Expands the command display in-place and removes
  the view option after use.
- CLI callbacks (callbacks.py): 'view' choice added to the list when
  the command exceeds 70 characters.
- Gateway (gateway/run.py): 'full', 'show', 'view' responses reveal
  the complete command while keeping the approval pending.

Includes 7 new tests covering view-then-approve, view-then-deny,
short command fallthrough, and double-view behavior.

Closes community feedback about the 80-char cap on dangerous commands.

0aa31cd3cb feat: call_llm/async_call_llm + config slots + migrate all consumers
Add centralized call_llm() and async_call_llm() functions that own the
full LLM request lifecycle:
  1. Resolve provider + model from task config or explicit args
  2. Get or create a cached client for that provider
  3. Format request args (max_tokens handling, provider extra_body)
  4. Make the API call with max_tokens/max_completion_tokens retry
  5. Return the response

Config: expanded auxiliary section with provider:model slots for all
tasks (compression, vision, web_extract, session_search, skills_hub,
mcp, flush_memories). Config version bumped to 7.

Migrated all auxiliary consumers:
- context_compressor.py: uses call_llm(task='compression')
- vision_tools.py: uses async_call_llm(task='vision')
- web_tools.py: uses async_call_llm(task='web_extract')
- session_search_tool.py: uses async_call_llm(task='session_search')
- browser_tool.py: uses call_llm(task='vision'/'web_extract')
- mcp_tool.py: uses call_llm(task='mcp')
- skills_guard.py: uses call_llm(provider='openrouter')
- run_agent.py flush_memories: uses call_llm(task='flush_memories')

Tests updated for context_compressor and MCP tool. Some test mocks
still need updating (15 remaining failures from mock pattern changes,
2 pre-existing).

4a8f23eddf fix: correctly track failed MCP server connections in discovery
_discover_one() caught all exceptions and returned [], making
asyncio.gather(return_exceptions=True) redundant. The
isinstance(result, Exception) branch in _discover_all() was dead
code, so failed_count was always 0. This caused:
- No summary printed when all servers fail (silent failure)
- ok_servers always equaling total_servers (misleading count)
- Unused variables transport_desc and transport_type

Fix: let exceptions propagate to gather() so failed_count increments
correctly. Move per-server failure logging to _discover_all(). Remove
dead variables.

9423fda5cb feat: configurable subagent provider:model with full credential resolution
Adds delegation.model and delegation.provider config fields so subagents
can run on a completely different provider:model pair than the parent agent.

When delegation.provider is set, the system resolves the full credential
bundle (base_url, api_key, api_mode) via resolve_runtime_provider() —
the same path used by CLI/gateway startup. This means all configured
providers work out of the box: openrouter, nous, zai, kimi-coding,
minimax, minimax-cn.

Key design decisions:
- Provider resolution uses hermes_cli.runtime_provider (single source of
  truth for credential resolution across CLI, gateway, cron, and now
  delegation)
- When only delegation.model is set (no provider), the model name changes
  but parent credentials are inherited (for switching models within the
  same provider like OpenRouter)
- When delegation.provider is set, full credentials are resolved
  independently — enabling cross-provider delegation (e.g. parent on
  Nous Portal, subagents on OpenRouter)
- Clear error messages if provider resolution fails (missing API key,
  unknown provider name)
- _load_config() now falls back to hermes_cli.config.load_config() for
  gateway/cron contexts where CLI_CONFIG is unavailable

Based on PR #791 by 0xbyt4 (closes #609), reworked to use proper
provider credential resolution instead of passing provider as metadata.

24479625a2 fix: Docker backend fails when docker is not in PATH (macOS gateway)
On macOS, Docker Desktop installs the CLI to /usr/local/bin/docker, but
when Hermes runs as a gateway service (launchd) or in other non-login
contexts, /usr/local/bin is often not in PATH. This causes the Docker
requirements check to fail with 'No such file or directory: docker' even
though docker works fine from the user's terminal.

Add find_docker() helper that uses shutil.which() first, then probes
common Docker Desktop install paths on macOS (/usr/local/bin,
/opt/homebrew/bin, Docker.app bundle). The resolved path is cached and
passed to mini-swe-agent via its 'executable' parameter.

- tools/environments/docker.py: add find_docker(), use it in
  _storage_opt_supported() and pass to _Docker(executable=...)
- tools/terminal_tool.py: use find_docker() in requirements check
- tests/tools/test_docker_find.py: 4 tests (PATH, fallback, not found, cache)

03a4f184e6 fix: call _stop_training_run on early-return failure paths
The 4 early-return paths in _spawn_training_run (API exit, trainer
exit, env not found, env exit) were doing manual process.terminate()
or returning without cleanup, leaking open log file handles. Now all
paths call _stop_training_run() which handles both process termination
and file handle closure.

Also adds 12 tests for _stop_training_run covering file handle
cleanup, process termination, status transitions, and edge cases.

Inspired by PR #715 (0xbyt4) which identified the early-return issue.

a458b535c9 fix: improve read-loop detection — consecutive-only, correct thresholds, fix bugs
Follow-up to PR #705 (merged from 0xbyt4). Addresses several issues:

1. CONSECUTIVE-ONLY TRACKING: Redesigned the read/search tracker to only
   warn/block on truly consecutive identical calls. Any other tool call
   in between (write, patch, terminal, etc.) resets the counter via
   notify_other_tool_call(), called from handle_function_call() in
   model_tools.py. This prevents false blocks in read→edit→verify flows.

2. THRESHOLD ADJUSTMENT: Warn on 3rd consecutive (was 2nd), block on
   4th+ consecutive (was 3rd+). Gives the model more room before
   intervening.

3. TUPLE UNPACKING BUG: Fixed get_read_files_summary() which crashed on
   search keys (5-tuple) when trying to unpack as 3-tuple. Now uses a
   separate read_history set that only tracks file reads.

4. WEB_EXTRACT DOCSTRING: Reverted incorrect removal of 'title' from
   web_extract return docs in code_execution_tool.py — the field IS
   returned by web_tools.py.

5. TESTS: Rewrote test_read_loop_detection.py (35 tests) to cover
   consecutive-only behavior, notify_other_tool_call, interleaved
   read/search, and summary-unaffected-by-searches.

c1171fe666 fix: eliminate 3x SQLite message duplication in gateway sessions (#860)
Three separate code paths all wrote to the same SQLite state.db with
no deduplication, inflating session transcripts by 3-4x:

1. _log_msg_to_db() — wrote each message individually after append
2. _flush_messages_to_session_db() — re-wrote ALL new messages at
   every _persist_session() call (~18 exit points), with no tracking
   of what was already written
3. gateway append_to_transcript() — wrote everything a third time
   after the agent returned

Since load_transcript() prefers SQLite over JSONL, the inflated data
was loaded on every session resume, causing proportional token waste.

Fix:
- Remove _log_msg_to_db() and all 16 call sites (redundant with flush)
- Add _last_flushed_db_idx tracking in _flush_messages_to_session_db()
  so repeated _persist_session() calls only write truly new messages
- Reset flush cursor on compression (new session ID)
- Add skip_db parameter to SessionStore.append_to_transcript() so the
  gateway skips SQLite writes when the agent already persisted them
- Gateway now passes skip_db=True for agent-managed messages, still
  writes to JSONL as backup

Verified: a 12-message CLI session with tool calls produces exactly
12 SQLite rows with zero duplicates (previously would be 36-48).

Tests: 9 new tests covering flush deduplication, skip_db behavior,
compression reset, and initialization. Full suite passes (2869 tests).

with user-facing rollback.  Inspired by PR #559 (by @alireza78a).

Architecture:
- Shadow git repos at ~/.hermes/checkpoints/{hash}/ via GIT_DIR
- CheckpointManager: take/list/restore, turn-scoped dedup, pruning
- Transparent — the LLM never sees it, no tool schema, no tokens
- Once per turn — only first write_file/patch triggers a snapshot

Integration:
- Config: checkpoints.enabled + checkpoints.max_snapshots
- CLI flag: hermes --checkpoints
- Trigger: run_agent.py _execute_tool_calls() before write_file/patch
- /rollback slash command in CLI + gateway (list, restore by number)
- Pre-rollback snapshot auto-created on restore (undo the undo)

Safety:
- Never blocks file operations — all errors silently logged
- Skips root dir, home dir, dirs >50K files
- Disables gracefully when git not installed
- Shadow repo completely isolated from project git

Tests: 35 new tests, all passing (2798 total suite)

5212644861 fix(security): prevent shell injection in tilde-username path expansion
Validate that the username portion of ~username paths contains only
valid characters (alphanumeric, dot, hyphen, underscore) before passing
to shell echo for expansion. Previously, paths like '~; rm -rf /'
would be passed unquoted to self._exec(f'echo {path}'), allowing
arbitrary command execution.

The approach validates the username rather than using shlex.quote(),
which would prevent tilde expansion from working at all since
echo '~user' outputs the literal string instead of expanding it.

Added tests for injection blocking and valid ~username/path expansion.

4e3a8a0637 fix: handle empty choices in MCP sampling callback
SamplingHandler.__call__ accessed response.choices[0] without checking
if the list was non-empty. LLM APIs can return empty choices on content
filtering, provider errors, or rate limits, causing an unhandled
IndexError that propagates to the MCP SDK and may crash the connection.

Add a defensive guard that returns a proper ErrorData when choices is
empty, None, or missing. Includes three test cases covering all
variants.

654e16187e feat(mcp): add sampling support — server-initiated LLM requests (#753)
Add MCP sampling/createMessage capability via SamplingHandler class.

Text-only sampling + tool use in sampling with governance (rate limits,
model whitelist, token caps, tool loop limits). Per-server audit metrics.

Based on concept from PR #366 by eren-karakus0. Restructured as class-based
design with bug fixes and tests using real MCP SDK types.

50 new tests, 2600 total passing.

7af33accf1 fix: apply secret redaction to file tool outputs
Terminal output was already redacted via redact_sensitive_text() but
read_file and search_files returned raw content. Now both tools
redact secrets before returning results to the LLM.

Based on PR #372 by @teyrebaz33 (closes #363) — applied manually
due to branch conflicts with the current codebase.

a8bf414f4a feat: browser console/errors tool, annotated screenshots, auto-recording, and dogfood QA skill
New browser capabilities and a built-in skill for agent-driven web QA.

## New tool: browser_console

Returns console messages (log/warn/error/info) AND uncaught JavaScript
exceptions in a single call. Uses agent-browser's 'console' and 'errors'
commands through the existing session plumbing. Supports --clear to reset
buffers. Verified working in both local and Browserbase cloud modes.

## Enhanced tool: browser_vision(annotate=True)

New boolean parameter on browser_vision. When true, agent-browser overlays
numbered [N] labels on interactive elements — each [N] maps to ref @eN.
Annotation data (element name, role, bounding box) returned alongside the
vision analysis. Useful for QA reports and spatial reasoning.

## Config: browser.record_sessions

Auto-record browser sessions as WebM video files when enabled:
- Starts recording on first browser_navigate
- Stops and saves on browser_close
- Saves to ~/.hermes/browser_recordings/
- Works in both local and cloud modes (verified)
- Disabled by default

## Built-in skill: dogfood

Systematic exploratory QA testing for web applications. Teaches the agent
a 5-phase workflow:
1. Plan — accept URL, create output dirs, set scope
2. Explore — systematic crawl with annotated screenshots
3. Collect Evidence — screenshots, console errors, JS exceptions
4. Categorize — severity (Critical/High/Medium/Low) and category
   (Functional/Visual/Accessibility/Console/UX/Content)
5. Report — structured markdown with per-issue evidence

Includes:
- skills/dogfood/SKILL.md — full workflow instructions
- skills/dogfood/references/issue-taxonomy.md — severity/category defs
- skills/dogfood/templates/dogfood-report-template.md — report template

## Tests

21 new tests covering:
- browser_console message/error parsing, clear flag, empty/failed states
- browser_console schema registration
- browser_vision annotate schema and flag passing
- record_sessions config defaults and recording lifecycle
- Dogfood skill file existence and content validation

Addresses #315.

491605cfea feat: add high-value tool result hints for patch and search_files (#722)
Add contextual [Hint: ...] suffixes to tool results where they save
real iterations:

- patch (no match): suggests read_file/search_files to verify content
  before retrying — addresses the common pattern where the agent retries
  with stale old_string instead of re-reading the file.
- search_files (truncated): provides explicit next offset and suggests
  narrowing the search — clearer than relying on total_count inference.

Other hints proposed in #722 (terminal, web_search, web_extract,
browser_snapshot, search zero-results, search content-matches) were
evaluated and found to be low-value: either already covered by existing
mechanisms (read_file pagination, similar-files, schema descriptions)
or guidance the agent already follows from its own reasoning.

5 new tests covering hint presence/absence for both tools.

c0520223fd fix: clipboard BMP conversion file loss and broken test
Source code (hermes_cli/clipboard.py):
- _convert_to_png() lost the file when both Pillow and ImageMagick were
  unavailable: path.rename(tmp) moved the file to .bmp, then subprocess.run
  raised FileNotFoundError, but the file was never renamed back. The final
  fallback 'return path.exists()' returned False.
- Fix: restore the original file in both except handlers by renaming tmp
  back to path when the original is missing.

Test (tests/tools/test_clipboard.py):
- test_file_still_usable_when_no_converter expected 'from PIL import Image'
  to raise an Exception, but Pillow is installed so pytest.raises fired
  'DID NOT RAISE'. The test also never called _convert_to_png().
- Fix: properly mock PIL unavailability via patch.dict(sys.modules),
  actually call _convert_to_png(), and assert the correct result.

3fb8938cd3 fix: search_files now reports error for non-existent paths instead of silent empty results
Previously, search_files would silently return 0 results when the
search path didn't exist (e.g., /root/.hermes/... when HOME is
/home/user). The path was passed to rg/grep/find which would fail
silently, and the empty stdout was parsed as 'no matches found'.

Changes:
- Add path existence check at the top of search() using test -e.
  Returns SearchResult with a clear error message when path doesn't exist.
- Add exit code 2 checks in _search_with_rg() and _search_with_grep()
  as secondary safety net for other error types (bad regex, permissions).
- Add 4 new tests covering: nonexistent path (content mode), nonexistent
  path (files mode), existing path proceeds normally, rg error exit code.

Tests: 37 → 41 in test_file_operations.py, full suite 2330 passed.
