7ca22ea11b fix(compression): restore sane defaults and cap summary at 12K tokens
- threshold: 0.80 → 0.50 (compress at 50%, not 80%)
- target_ratio: 0.40 → 0.20, now relative to threshold not total context
  (20% of 50% = 10% of context as tail budget)
- summary ceiling: 32K → 12K (Gemini can't output more than ~12K)
- Updated DEFAULT_CONFIG, config display, example config, and tests

ef47531617 docs: unify hooks documentation — add plugin hooks to hooks page, add session:end event
The hooks page only documented gateway event hooks (HOOK.yaml system).
The plugins page listed plugin hooks (pre_tool_call, etc.) that weren't
referenced from the hooks page, which was confusing.

Changes:
- hooks.md: Add overview table showing both hook systems
- hooks.md: Add Plugin Hooks section with available hooks, callback
  signatures, and example
- hooks.md: Add missing session:end gateway event (emitted but undocumented)
- hooks.md: Mark pre_llm_call, post_llm_call, on_session_start,
  on_session_end as planned (defined in VALID_HOOKS but not yet invoked)
- hooks.md: Update info box to cross-reference plugin hooks
- hooks.md: Fix heading hierarchy (gateway content as subsections)
- plugins.md: Add cross-reference to hooks page for full details
- plugins.md: Mark planned hooks as (planned)

27c023e071 feat(config): expose compression target_ratio, protect_last_n, and threshold in DEFAULT_CONFIG
PR #2554 made these configurable via config.yaml but didn't add them
to DEFAULT_CONFIG or the config display. Users couldn't discover the
new knobs without reading the source.

- threshold: 0.80 (compress at 80% context usage)
- target_ratio: 0.40 (preserve 40% of context as recent tail)
- protect_last_n: 20 (keep last 20 messages uncompressed)
- Updated hermes config display to show all three fields

9231a335d4 fix(compression): replace dead summary_target_tokens with ratio-based scaling (#2554)
The summary_target_tokens parameter was accepted in the constructor,
stored on the instance, and never used — the summary budget was always
computed from hardcoded module constants (_SUMMARY_RATIO=0.20,
_MAX_SUMMARY_TOKENS=8000). This caused two compounding problems:

1. The config value was silently ignored, giving users no control
   over post-compression size.
2. Fixed budgets (20K tail, 8K summary cap) didn't scale with
   context window size. Switching from a 1M-context model to a
   200K model would trigger compression that nuked 350K tokens
   of conversation history down to ~30K.

Changes:
- Replace summary_target_tokens with summary_target_ratio (default 0.40)
  which sets the post-compression target as a fraction of context_length.
  Tail token budget and summary cap now scale proportionally:
    MiniMax 200K → ~80K post-compression
    GPT-5   1M  → ~400K post-compression
- Change threshold_percent default: 0.50 → 0.80 (don't fire until
  80% of context is consumed)
- Change protect_last_n default: 4 → 20 (preserve ~10 full turns)
- Summary token cap scales to 5% of context (was fixed 8K), capped
  at 32K ceiling
- Read target_ratio and protect_last_n from config.yaml compression
  section (both are now configurable)
- Remove hardcoded summary_target_tokens=500 from run_agent.py
- Add 5 new tests for ratio scaling, clamping, and new defaults

8ee4f32819 fix(gateway): use TERMINAL_CWD for context file discovery, not process cwd
The gateway process runs from the hermes-agent install directory, so
os.getcwd() picks up the repo's AGENTS.md (16k chars) and other dev
context files — inflating input tokens by ~10k on every gateway message.

Fix: use TERMINAL_CWD (which the gateway sets to MESSAGING_CWD or
$HOME) as the cwd for build_context_files_prompt(). In CLI mode,
TERMINAL_CWD is the user's actual project directory, so behavior
is unchanged.

Before: gateway 15-20k input tokens, CLI 6-8k
After:  gateway ~6-8k input tokens (same as CLI)

ac5b8a478a ci: add supply chain audit workflow for PR scanning (#2816)
Scans every PR diff for patterns associated with supply chain attacks:

CRITICAL (blocks merge):
- .pth files (auto-execute on Python startup — litellm attack vector)
- base64 decode + exec/eval combo (obfuscated payload execution)
- subprocess with encoded/obfuscated commands

WARNING (comment only, no block):
- base64 encode/decode alone (legitimate uses: images, JWT, etc.)
- exec/eval alone
- Outbound POST/PUT requests
- setup.py/sitecustomize.py/usercustomize.py changes
- marshal.loads/pickle.loads/compile()

Posts a detailed comment on the PR with matched lines and context.
Excludes lockfiles (uv.lock, package-lock.json) from scanning.

Motivated by the litellm 1.82.7/1.82.8 credential stealer attack
(BerriAI/litellm#24512).

624e4a8e7a chore: regenerate uv.lock with hashes, use lockfile in setup (#2812)

- Add python_version marker to yc-bench (requires >=3.12)
- Update setup-hermes.sh to prefer 'uv sync --locked' for hash-verified
  installs, with fallback to 'uv pip install' when lockfile is stale

This completes the supply chain hardening: pyproject.toml bounds the
version ranges, and uv.lock pins exact versions with cryptographic
hashes so tampered packages are rejected at install time.

Replace all minisweagent imports with Hermes-Agent's own environment
classes (LocalEnvironment, DockerEnvironment, ModalEnvironment).

The runner now uses the same backends as the terminal tool, so Docker
and Modal environments work out of the box without extra submodules.

c9b76057d4 chore: pin all dependency version ranges (supply chain hardening) (#2810)
Adds upper-bound version pins (<next_major) to all dependencies in
pyproject.toml — both core and optional. Previously most deps were
unpinned or had only floor bounds, meaning fresh installs would pull
whatever version was latest on PyPI.

This limits blast radius from supply chain attacks like the litellm
1.82.7/1.82.8 credential stealer (BerriAI/litellm#24512). With bounded
ranges, a compromised major version bump won't be pulled automatically.

Floors are set to current known-good installed versions.

745859babb feat: env var passthrough for skills and user config (#2807)
* feat: env var passthrough for skills and user config

Skills that declare required_environment_variables now have those vars
passed through to sandboxed execution environments (execute_code and
terminal).  Previously, execute_code stripped all vars containing KEY,
TOKEN, SECRET, etc. and the terminal blocklist removed Hermes
infrastructure vars — both blocked skill-declared env vars.

Two passthrough sources:

1. Skill-scoped (automatic): when a skill is loaded via skill_view and
   declares required_environment_variables, vars that are present in
   the environment are registered in a session-scoped passthrough set.

2. Config-based (manual): terminal.env_passthrough in config.yaml lets
   users explicitly allowlist vars for non-skill use cases.

Changes:
- New module: tools/env_passthrough.py — shared passthrough registry
- hermes_cli/config.py: add terminal.env_passthrough to DEFAULT_CONFIG
- tools/skills_tool.py: register available skill env vars on load
- tools/code_execution_tool.py: check passthrough before filtering
- tools/environments/local.py: check passthrough in _sanitize_subprocess_env
  and _make_run_env
- 19 new tests covering all layers

* docs: add environment variable passthrough documentation

Document the env var passthrough feature across four docs pages:

- security.md: new 'Environment Variable Passthrough' section with
  full explanation, comparison table, and security considerations
- code-execution.md: update security section, add passthrough subsection,
  fix comparison table
- creating-skills.md: add tip about automatic sandbox passthrough
- skills.md: add note about passthrough after secure setup docs

Live-tested: launched interactive CLI, loaded a skill with
required_environment_variables, verified TEST_SKILL_SECRET_KEY was
accessible inside execute_code sandbox (value: passthrough-test-value-42).

677b11d84c fix: reject relative cwd paths for container terminal backends
When TERMINAL_CWD is set to '.' or any relative path (common when the
CLI config defaults to cwd='.'), container backends (docker, modal,
singularity, daytona) would pass it directly to the container where it's
meaningless. This caused 'docker run -d -w .' to fail.

Now relative paths are caught alongside host paths and replaced with
the default '/root' for container backends.

02b38b93cb refactor: remove mini-swe-agent dependency — inline Docker/Modal backends (#2804)
Drop the mini-swe-agent git submodule. All terminal backends now use
hermes-agent's own environment implementations directly.

Docker backend:
- Inline the `docker run -d` container startup (was 15 lines in
  minisweagent's DockerEnvironment). Our wrapper already handled
  execute(), cleanup(), security hardening, volumes, and resource limits.

Modal backend:
- Import swe-rex's ModalDeployment directly instead of going through
  minisweagent's 90-line passthrough wrapper.
- Bake the _AsyncWorker pattern (from environments/patches.py) directly
  into ModalEnvironment for Atropos compatibility without monkey-patching.

Cleanup:
- Remove minisweagent_path.py (submodule path resolution helper)
- Remove submodule init/install from install.sh and setup-hermes.sh
- Remove mini-swe-agent from .gitmodules
- environments/patches.py is now a no-op (kept for backward compat)
- terminal_tool.py no longer does sys.path hacking for minisweagent
- mini_swe_runner.py guards imports (optional, for RL training only)
- Update all affected tests to mock the new direct subprocess calls
- Update README.md, CONTRIBUTING.md

No functionality change — all Docker, Modal, local, SSH, Singularity,
and Daytona backends behave identically. 6093 tests pass.

98b5570961 fix: make browser command timeout configurable via config.yaml (#2801)
browser_vision and other browser commands had a hardcoded 30-second
subprocess timeout that couldn't be overridden. Users with slower
machines (local Chromium without GPU) would hit timeouts on screenshot
capture even when setting browser.command_timeout in config.yaml,
because nothing read that value.

Changes:
- Add browser.command_timeout to DEFAULT_CONFIG (default: 30s)
- Add _get_command_timeout() helper that reads config, falls back to 30s
- _run_browser_command() now defaults to config value instead of constant
- browser_vision screenshot no longer hardcodes timeout=30
- browser_navigate uses max(config_timeout, 60) as floor for navigation

2e524272b1 refactor(model): extract shared switch_model() from CLI and gateway handlers
Phase 4 of the /model command overhaul.

Both the CLI (cli.py) and gateway (gateway/run.py) /model handlers
had ~50 lines of duplicated core logic: parsing, provider detection,
credential resolution, and model validation. This extracts that
pipeline into hermes_cli/model_switch.py.

New module exports:
- ModelSwitchResult: dataclass with all fields both handlers need
- CustomAutoResult: dataclass for bare '/model custom' results
- switch_model(): core pipeline — parse → detect → resolve → validate
- switch_to_custom_provider(): resolve endpoint + auto-detect model

The shared functions are pure (no I/O side effects). Each caller
handles its own platform-specific concerns:
- CLI: sets self.model/provider/etc, calls save_config_value(), prints
- Gateway: writes config.yaml directly, sets env vars, returns markdown

Net result: -244 lines from handlers, +234 lines in shared module.
The handlers are now ~80 lines each (down from ~150+) and can't drift
apart on core logic.

ce39f9cc44 fix(gateway): detect virtualenv path instead of hardcoding venv/ (#2797)
Fixes #2492.

`generate_systemd_unit()` and `get_python_path()` hardcoded `venv`
as the virtualenv directory name. When the virtualenv is `.venv`
(which `setup-hermes.sh` and `.gitignore` both reference), the
generated systemd unit had incorrect VIRTUAL_ENV and PATH variables.

Introduce `_detect_venv_dir()` which:
1. Checks `sys.prefix` vs `sys.base_prefix` to detect the active venv
2. Falls back to probing `.venv` then `venv` under PROJECT_ROOT

Both `get_python_path()` and `generate_systemd_unit()` now use
this detection instead of hardcoded paths.

18cbd18fa9 fix: remove litellm/typer/platformdirs from hermes-agent deps (supply chain compromise) (#2796)
litellm 1.82.7/1.82.8 contained a credential stealer (.pth auto-exec
payload). PyPI quarantined the entire package, blocking all fresh
hermes-agent installs since litellm was listed as a hard dependency.

These three deps (litellm, typer, platformdirs) are only used by the
mini-swe-agent submodule, which has its own pyproject.toml and manages
its own dependencies. They were redundantly duplicated in hermes-agent's
pyproject.toml.

Also fixes install.sh to not print 'mini-swe-agent installed' on
failure, and updates warning messages in both install scripts to clarify
that only Docker/Modal backends are affected — local terminal is
unaffected.

b641ee88f4 feat(model): /model command overhaul — Phases 2, 3, 5
* feat(model): persist base_url on /model switch, auto-detect for bare /model custom

Phase 2+3 of the /model command overhaul:

Phase 2 — Persist base_url on model switch:
- CLI: save model.base_url when switching to a non-OpenRouter endpoint;
  clear it when switching away from custom to prevent stale URLs
  leaking into the new provider's resolution
- Gateway: same logic using direct YAML write

Phase 3 — Better feedback and edge cases:
- Bare '/model custom' now auto-detects the model from the endpoint
  using _auto_detect_local_model() and saves all three config values
  (model, provider, base_url) atomically
- Shows endpoint URL in success messages when switching to/from
  custom providers (both CLI and gateway)
- Clear error messages when no custom endpoint is configured
- Updated test assertions for the additional save_config_value call

Fixes #2562 (Phase 2+3)

* feat(model): support custom:name:model triple syntax for named custom providers

Phase 5 of the /model command overhaul.

Extends parse_model_input() to handle the triple syntax:
  /model custom:local-server:qwen → provider='custom:local-server', model='qwen'
  /model custom:my-model          → provider='custom', model='my-model' (unchanged)

The 'custom:local-server' provider string is already supported by
_get_named_custom_provider() in runtime_provider.py, which matches
it against the custom_providers list in config.yaml. This just wires
the parsing so users can do it from the /model slash command.

Added 4 tests covering single, triple, whitespace, and empty model cases.

2f1c4fb01f fix(auth): preserve 'custom' provider instead of silently remapping to 'openrouter'
resolve_provider('custom') was silently returning 'openrouter', causing
users who set provider: custom in config.yaml to unknowingly route
through OpenRouter instead of their local/custom endpoint. The display
showed 'via openrouter' even when the user explicitly chose custom.

Changes:
- auth.py: Split the conditional so 'custom' returns 'custom' as-is
- runtime_provider.py: _resolve_named_custom_runtime now returns
  provider='custom' instead of 'openrouter'
- runtime_provider.py: _resolve_openrouter_runtime returns
  provider='custom' when that was explicitly requested
- Add 'no-key-required' placeholder for keyless local servers
- Update existing test + add 5 new tests covering the fix

4313b8aff6 fix(cli): ensure single closure of streaming boxes during tool generation
- Updated `_on_tool_gen_start` method in `HermesCLI` to close open streaming boxes exactly once, preventing potential multiple closures.
- Added a check for `_stream_box_opened` to manage the state of the streaming box more effectively, enhancing user experience during large payload streaming.

87e2626cf6 feat(cli, agent): add tool generation callback for streaming updates
- Introduced `_on_tool_gen_start` in `HermesCLI` to indicate when tool-call arguments are being generated, enhancing user feedback during streaming.
- Updated `AIAgent` to support a new `tool_gen_callback`, notifying the display layer when tool generation starts, allowing for better user experience during large payloads.
- Ensured that the callback is triggered appropriately during streaming events to prevent user interface freezing.

1345e93393 fix: add macOS Homebrew paths to browser and terminal PATH resolution
On macOS with Homebrew (Apple Silicon), Node.js and agent-browser
binaries live under /opt/homebrew/bin/ which is not included in the
_SANE_PATH fallback used by browser_tool.py and environments/local.py.
When Hermes runs with a filtered PATH (e.g. as a systemd service),
these binaries are invisible, causing 'env: node: No such file or
directory' errors when using browser tools.

Changes:
- Add /opt/homebrew/bin and /opt/homebrew/sbin to _SANE_PATH in both
  browser_tool.py and environments/local.py
- Add _discover_homebrew_node_dirs() to find versioned Node installs
  (e.g. brew install node@24) that aren't linked into /opt/homebrew/bin
- Extend _find_agent_browser() to search Homebrew and Hermes-managed
  dirs when agent-browser isn't on the current PATH
- Include discovered Homebrew node dirs in subprocess PATH when
  launching agent-browser
- Add 11 new tests covering all Homebrew path discovery logic

48b5bc6038 fix(gateway): prevent stale memory overwrites by flush agent (#2670)
The gateway memory flush agent reviews old conversation history on session
reset/expiry and writes to memory. It had no awareness of memory changes
made after that conversation ended (by the live agent, cron jobs, or other
sessions), causing silent overwrites of newer entries.

Two fixes:

1. Skip memory flush entirely for cron sessions (session IDs starting with
   'cron_'). Cron sessions are headless with no meaningful user conversation
   to extract memories from.

2. Inject the current live memory state (MEMORY.md + USER.md) directly into
   the flush prompt. The flush agent can now see what's already saved and
   make informed decisions — only adding genuinely new information rather
   than blindly overwriting entries that may have been updated since the
   conversation ended.

Addresses the root cause identified in #2670: the flush agent was making
memory decisions blind to the current state of memory, causing stale
context to overwrite newer entries on gateway restarts and session resets.

4ff73fb32c feat(config): support ${ENV_VAR} substitution in config.yaml (#2684)
* feat(config): support ${ENV_VAR} substitution in config.yaml

* fix: extend env var expansion to CLI and gateway config loaders

The original PR (#2680) only wired _expand_env_vars into load_config(),
which is used by 'hermes tools' and 'hermes setup'. The two primary
config paths were missed:

- load_cli_config() in cli.py (interactive CLI)
- Module-level _cfg in gateway/run.py (gateway — bridges api_keys to env vars)

Also:
- Remove redundant 'import re' (already imported at module level)
- Add missing blank lines between top-level functions (PEP 8)
- Add tests for load_cli_config() expansion

73a88a02fe fix(security): prevent shell injection in _expand_path via ~user path suffix (#2047)
echo was called with the full unquoted path (~username/suffix), allowing
command substitution in the suffix (e.g. ~user/$(malicious)) to execute
arbitrary shell commands. The fix expands only the validated ~username
portion via the shell and concatenates the suffix as a plain string.

f9c2565ab4 fix(config): log warning instead of silently swallowing config.yaml errors (#2683)
A bare `except Exception: pass` meant any YAML syntax error, bad value,
or unexpected structure in config.yaml was silently ignored and the
gateway fell back to .env / gateway.json without any indication.
Users had no way to know why their config changes had no effect.

0791efe2c3 fix(security): add SSRF protection to vision_tools and web_tools (hardened)
* fix(security): add SSRF protection to vision_tools and web_tools

Both vision_analyze and web_extract/web_crawl accept arbitrary URLs
without checking if they target private/internal network addresses.
A prompt-injected or malicious skill could use this to access cloud
metadata endpoints (169.254.169.254), localhost services, or private
network hosts.

Adds a shared url_safety.is_safe_url() that resolves hostnames and
blocks private, loopback, link-local, and reserved IP ranges. Also
blocks known internal hostnames (metadata.google.internal).

Integrated at the URL validation layer in vision_tools and before
each website_policy check in web_tools (extract, crawl).

* test(vision): update localhost test to reflect SSRF protection

The existing test_valid_url_with_port asserted localhost URLs pass
validation. With SSRF protection, localhost is now correctly blocked.
Update the test to verify the block, and add a separate test for
valid URLs with ports using a public hostname.

* fix(security): harden SSRF protection — fail-closed, CGNAT, multicast, redirect guard

Follow-up hardening on top of dieutx's SSRF protection (PR #2630):

- Change fail-open to fail-closed: DNS errors and unexpected exceptions
  now block the request instead of allowing it (OWASP best practice)
- Block CGNAT range (100.64.0.0/10): Python's ipaddress.is_private
  does NOT cover this range (returns False for both is_private and
  is_global). Used by Tailscale/WireGuard and carrier infrastructure.
- Add is_multicast and is_unspecified checks: multicast (224.0.0.0/4)
  and unspecified (0.0.0.0) addresses were not caught by the original
  four-check chain
- Add redirect guard for vision_tools: httpx event hook re-validates
  each redirect target against SSRF checks, preventing the classic
  redirect-based SSRF bypass (302 to internal IP)
- Move SSRF filtering before backend dispatch in web_extract: now
  covers Parallel and Tavily backends, not just Firecrawl
- Extract _is_blocked_ip() helper for cleaner IP range checking
- Add 24 new tests (CGNAT, multicast, IPv4-mapped IPv6, fail-closed
  behavior, parametrized blocked/allowed IP lists)
- Fix existing tests to mock DNS resolution for test hostnames

934fbe3c06 fix: strip ANSI at the source — clean terminal output before it reaches the model
Root cause: terminal_tool, execute_code, and process_registry returned raw
subprocess output with ANSI escape sequences intact. The model saw these
in tool results and copied them into file writes.

Previous fix (PR #2532) stripped ANSI at the write point in file_tools.py,
but this was a band-aid — regex on file content risks corrupting legitimate
content, and doesn't prevent ANSI from wasting tokens in the model context.

Source-level fix:
- New tools/ansi_strip.py with comprehensive ECMA-48 regex covering CSI
  (incl. private-mode, colon-separated, intermediate bytes), OSC (both
  terminators), DCS/SOS/PM/APC strings, Fp/Fe/Fs/nF escapes, 8-bit C1
- terminal_tool.py: strip output before returning to model
- code_execution_tool.py: strip stdout/stderr before returning
- process_registry.py: strip output in poll/read_log/wait
- file_tools.py: remove _strip_ansi band-aid (no longer needed)

Verified: `ls --color=always` output returned as clean text to model,
file written from that output contains zero ESC bytes.

6302e56e7c fix(gateway): add all missing platform allowlist env vars to startup warning check (#2628)
* fix(gateway): added MATRIX_ALLOWED_USERS to list of env vars checked by gateway

* fix(gateway): add all missing platform allowlist env vars to startup check

The startup warning for 'No user allowlists configured' was only checking
TELEGRAM, DISCORD, WHATSAPP, SLACK, and SMS — missing SIGNAL, EMAIL,
MATTERMOST, and DINGTALK. Users of those platforms would see a spurious
warning even with their platform-specific allowlist configured.

Now matches the canonical platform_env_map in _is_user_authorized().

868b3c07e3 fix: platform default toolsets silently override tool deselection in hermes tools (#2624)
Cherry-picked from PR #2576 by ereid7, plus read-side fix from 173a5c62.

Both fixes were originally landed in 173a5c62 but were inadvertently
reverted by commit 34be3f8b (a squash-merge that bundled unrelated
tools_config.py changes).

Save side (_save_platform_tools): exclude platform default toolset
names (hermes-cli, hermes-telegram) from preserved entries so they
don't silently re-enable everything.

Read side (_get_platform_tools): when the saved list contains explicit
configurable keys, use direct membership instead of subset inference.
The subset approach is broken when composite toolsets like hermes-cli
resolve to ALL tools.

9d6148316c fix: media delivery fails for file paths containing spaces (#2621)
Cherry-picked from PR #2583 by Glucksberg.

The MEDIA: regex used \S+ which truncated paths at the first space.
Added a space-aware alternative anchored to known media extensions.
Also updated extract_local_files to allow spaces in path segments.

Follow-up fix: changed \s to [^\S\n] in the space-matching group
so the regex doesn't greedily match across newlines (broke multi-line
MEDIA: tags).
