8eb70a6885 fix(email): close SMTP and IMAP connections on failure (#3804)
SMTP connections in _send_email() and _send_email_with_attachment() leak
when login() or send_message() raises before quit() is reached. Both now
wrapped in try/finally with a close() fallback if quit() also fails.

IMAP connection in _fetch_new_messages() leaks when UID processing raises,
since logout() sits after the loop. Restructured with try/finally so
logout() runs unconditionally.

0f042f3930 fix(email): filter automated/noreply senders to prevent reply loops (salvage #3461) (#3606)
* fix(gateway): filter automated/noreply senders in email adapter

Fixes #3453

Adds noreply/automated sender filtering to the email adapter. Drops emails from noreply, mailer-daemon, postmaster addresses and bulk mail headers (Auto-Submitted, Precedence, List-Unsubscribe) before dispatching. Prevents pairing codes and AI responses being sent to automated senders.

* fix: remove redundant seen_uids add + trailing whitespace cleanup

6ed9740444 fix: prevent unbounded growth of _seen_uids in EmailAdapter (#3490)
EmailAdapter._seen_uids accumulates every IMAP UID ever seen but
never removes any. A long-running gateway processing a high-volume
inbox would leak memory indefinitely — thousands of integers per day.

IMAP UIDs are monotonically increasing integers, so old UIDs are safe
to drop: new messages always have higher UIDs, and the IMAP UNSEEN
flag already prevents re-delivery regardless of our local tracking.

Fix adds _trim_seen_uids() which keeps only the most recent 1000 UIDs
(half of the 2000-entry cap) when the set grows too large. Called
automatically during connect() and after each fetch cycle.

3a86328847 fix(gateway): add request timeouts to HA, Email, Mattermost, SMS adapters (#3258)
Add timeout=30 to all bare ClientSession, IMAP4_SSL, smtplib.SMTP, and
ws_connect calls that previously had no timeout, preventing indefinite
hangs when an external server is slow or unresponsive.

Adapters hardened:
- HomeAssistant: REST + WS session creation, ws_connect handshake
- Email: all IMAP4_SSL (x2) and smtplib.SMTP (x3) calls
- Mattermost: session creation, _api_get, _api_post, _upload_file (60s)
- SMS: session creation in connect() + fallback session in send()

Salvaged from PRs #3161, #3168, #3170 (memosr) and #3201 (binhnt92).
SMS fallback ClientSession on send() also patched (missed in #3201).

8bb1d15da4 chore: remove ~100 unused imports across 55 files (#3016)
Automated cleanup via pyflakes + autoflake with manual review.

Changes:
- Removed unused stdlib imports (os, sys, json, pathlib.Path, etc.)
- Removed unused typing imports (List, Dict, Any, Optional, Tuple, Set, etc.)
- Removed unused internal imports (hermes_cli.auth, hermes_cli.config, etc.)
- Fixed cli.py: removed 8 shadowed banner imports (imported from hermes_cli.banner
  then immediately redefined locally — only build_welcome_banner is actually used)
- Added noqa comments to imports that appear unused but serve a purpose:
  - Re-exports (gateway/session.py SessionResetPolicy, tools/terminal_tool.py
    is_interrupted/_interrupt_event)
  - SDK presence checks in try/except (daytona, fal_client, discord)
  - Test mock targets (auxiliary_client.py Path, mcp_config.py get_hermes_home)

Zero behavioral changes. Full test suite passes (6162/6162, 2 pre-existing
streaming test failures unrelated to this change).

f3301a31d5 fix(email): guard against IndexError when IMAP search returns empty list
imap.uid('search') can return data=[] when the mailbox is empty or
has no matching messages. Accessing data[0] without checking len first
raises IndexError: list index out of range.

Fixed at both call sites in gateway/platforms/email.py:
- Line 233 (connect): ALL search on startup
- Line 298 (fetch): UNSEEN search in the polling loop

Closes #2137

6c6d12033f fix: email send_typing metadata + ☤ Hermes staff symbol (#1431, #1420)
* fix: prevent infinite 400 failure loop on context overflow (#1630)

When a gateway session exceeds the model's context window, Anthropic may
return a generic 400 invalid_request_error with just 'Error' as the
message.  This bypassed the phrase-based context-length detection,
causing the agent to treat it as a non-retryable client error.  Worse,
the failed user message was still persisted to the transcript, making
the session even larger on each attempt — creating an infinite loop.

Three-layer fix:

1. run_agent.py — Fallback heuristic: when a 400 error has a very short
   generic message AND the session is large (>40% of context or >80
   messages), treat it as a probable context overflow and trigger
   compression instead of aborting.

2. run_agent.py + gateway/run.py — Don't persist failed messages:
   when the agent returns failed=True before generating any response,
   skip writing the user's message to the transcript/DB. This prevents
   the session from growing on each failure.

3. gateway/run.py — Smarter error messages: detect context-overflow
   failures and suggest /compact or /reset specifically, instead of a
   generic 'try again' that will fail identically.

* fix(skills): detect prompt injection patterns and block cache file reads

Adds two security layers to prevent prompt injection via skills hub
cache files (#1558):

1. read_file: blocks direct reads of ~/.hermes/skills/.hub/ directory
   (index-cache, catalog files). The 3.5MB clawhub_catalog_v1.json
   was the original injection vector — untrusted skill descriptions
   in the catalog contained adversarial text that the model executed.

2. skill_view: warns when skills are loaded from outside the trusted
   ~/.hermes/skills/ directory, and detects common injection patterns
   in skill content ("ignore previous instructions", "<system>", etc.).

Cherry-picked from PR #1562 by ygd58.

* fix(tools): chunk long messages in send_message_tool before dispatch (#1552)

Long messages sent via send_message tool or cron delivery silently
failed when exceeding platform limits. Gateway adapters handle this
via truncate_message(), but the standalone senders in send_message_tool
bypassed that entirely.

- Apply truncate_message() chunking in _send_to_platform() before
  dispatching to individual platform senders
- Remove naive message[i:i+2000] character split in _send_discord()
  in favor of centralized smart splitting
- Attach media files to last chunk only for Telegram
- Add regression tests for chunking and media placement

* fix(approval): show full command in dangerous command approval (#1553)

Previously the command was truncated to 80 chars in CLI (with a
[v]iew full option), 500 chars in Discord embeds, and missing entirely
in Telegram/Slack approval messages. Now the full command is always
displayed everywhere:

- CLI: removed 80-char truncation and [v]iew full menu option
- Gateway (TG/Slack): approval_required message includes full command
  in a code block
- Discord: embed shows full command up to 4096-char limit
- Windows: skip SIGALRM-based test timeout (Unix-only)
- Updated tests: replaced view-flow tests with direct approval tests

* fix(cli): flush stdout during agent loop to prevent macOS display freeze (#1624)

The interrupt polling loop in chat() waited on the queue without
invalidating the prompt_toolkit renderer. On macOS, the StdoutProxy
buffer only flushed on input events, causing the CLI to appear frozen
during tool execution until the user typed a key.

Fix: call _invalidate() on each queue timeout (every ~100ms, throttled
to 150ms) to force the renderer to flush buffered agent output.

* fix(claw): warn when API keys are skipped during OpenClaw migration (#1580)

When --migrate-secrets is not passed (the default), API keys like
OPENROUTER_API_KEY are silently skipped with no warning. Users don't
realize their keys weren't migrated until the agent fails to connect.

Add a post-migration warning with actionable instructions: either
re-run with --migrate-secrets or add the key manually via
hermes config set.

* fix(security): block sandbox backend creds from subprocess env (#1264)

Add Modal and Daytona sandbox credentials to the subprocess env
blocklist so they're not leaked to agent terminal sessions via
printenv/env.

Cherry-picked from PR #1571 by ygd58.

* fix(gateway): cap interrupt recursion depth to prevent resource exhaustion (#816)

When a user sends multiple messages while the agent keeps failing,
_run_agent() calls itself recursively with no depth limit. This can
exhaust stack/memory if the agent is in a failure loop.

Add _MAX_INTERRUPT_DEPTH = 3. When exceeded, the pending message is
logged and the current result is returned instead of recursing deeper.

The log handler duplication bug described in #816 was already fixed
separately (AIAgent.__init__ deduplicates handlers).

* fix(gateway): /model shows active fallback model instead of config default (#1615)

When the agent falls back to a different model (e.g. due to rate
limiting), /model still showed the config default. Now tracks the
effective model/provider after each agent run and displays it.

Cleared when the primary model succeeds again or the user explicitly
switches via /model.

Cherry-picked from PR #1616 by MaxKerkula. Added hasattr guard for
test compatibility.

* feat(gateway): inject reply-to message context for out-of-session replies (#1594)

When a user replies to a Telegram message, check if the quoted text
exists in the current session transcript. If missing (from cron jobs,
background tasks, or old sessions), prepend [Replying to: "..."] to
the message so the agent has context about what's being referenced.

- Add reply_to_text field to MessageEvent (base.py)
- Populate from Telegram's reply_to_message (text or caption)
- Inject context in _handle_message when not found in history

Based on PR #1596 by anpicasso (cherry-picked reply-to feature only,
excluded unrelated /server command and background delegation changes).

* fix: recognize Claude Code OAuth credentials in startup gate (#1455)

The _has_any_provider_configured() startup check didn't look for
Claude Code OAuth credentials (~/.claude/.credentials.json). Users
with only Claude Code auth got the setup wizard instead of starting.

Cherry-picked from PR #1455 by kshitijk4poor.

* perf: use ripgrep for file search (200x faster than find)

search_files(target='files') now uses rg --files -g instead of find.
Ripgrep respects .gitignore, excludes hidden dirs by default, and has
parallel directory traversal — ~200x faster on wide trees (0.14s vs 34s
benchmarked on 164-repo tree).

Falls back to find when rg is unavailable, preserving hidden-dir
exclusion and BSD find compatibility.

Salvaged from PR #1464 by @light-merlin-dark (Merlin) — adapted to
preserve hidden-dir exclusion added since the original PR.

* refactor(tts): replace NeuTTS optional skill with built-in provider + setup flow

Remove the optional skill (redundant now that NeuTTS is a built-in TTS
provider). Replace neutts_cli dependency with a standalone synthesis
helper (tools/neutts_synth.py) that calls the neutts Python API directly
in a subprocess.

Add TTS provider selection to hermes setup:
- 'hermes setup' now prompts for TTS provider after model selection
- 'hermes setup tts' available as standalone section
- Selecting NeuTTS checks for deps and offers to install:
  espeak-ng (system) + neutts[all] (pip)
- ElevenLabs/OpenAI selections prompt for API keys
- Tool status display shows NeuTTS install state

Changes:
- Remove optional-skills/mlops/models/neutts/ (skill + CLI scaffold)
- Add tools/neutts_synth.py (standalone synthesis subprocess helper)
- Move jo.wav/jo.txt to tools/neutts_samples/ (bundled default voice)
- Refactor _generate_neutts() — uses neutts API via subprocess, no
  neutts_cli dependency, config-driven ref_audio/ref_text/model/device
- Add TTS setup to hermes_cli/setup.py (SETUP_SECTIONS, tool status)
- Update config.py defaults (ref_audio, ref_text, model, device)

* fix(docker): add explicit env allowlist for container credentials (#1436)

Docker terminal sessions are secret-dark by default. This adds
terminal.docker_forward_env as an explicit allowlist for env vars
that may be forwarded into Docker containers.

Values resolve from the current shell first, then fall back to
~/.hermes/.env. Only variables the user explicitly lists are
forwarded — nothing is auto-exposed.

Cherry-picked from PR #1449 by @teknium1, conflict-resolved onto
current main.

Fixes #1436
Supersedes #1439

* fix: email send_typing metadata param + ☤ Hermes staff symbol

- email.py: add missing metadata parameter to send_typing() to match
  BasePlatformAdapter signature (PR #1431 by @ItsChoudhry)
- README.md: ⚕ → ☤ — the caduceus is Hermes's staff, not the
  medical Staff of Asclepius (PR #1420 by @rianczerwinski)

8758e2e8d7 feat(email): add skip_attachments option via config.yaml
* feat(email): add skip_attachments option via config.yaml

Adds a config.yaml-driven option to skip email attachments in the
gateway email adapter. Useful for malware protection and bandwidth
savings.

Configure in config.yaml:
  platforms:
    email:
      skip_attachments: true

Based on PR #1521 by @an420eth, changed from env var to config.yaml
(via PlatformConfig.extra) to match the project's config-first pattern.

fa72f4ff55 fix: email adapter IMAP UID tracking and SMTP TLS verification
- Use imap.uid() for search and fetch instead of imap.search/fetch.
  Sequence numbers shift when messages are deleted, causing the adapter
  to skip new messages or reprocess old ones. UIDs are stable.

- Pass ssl.create_default_context() to starttls() so the server
  certificate is actually verified. Without it smtplib uses
  ssl._create_stdlib_context() which skips verification.
