The container exec-read piped the whole file through base64 with no size
guard — the 50MB cap was only enforced host-side AFTER the full payload
had already streamed into host memory. A prompt-injected read of a huge
container file (or /dev/zero) could balloon the gateway process.
head -c (cap+1) bounds the read inside the sandbox; the +1 byte lets the
host distinguish at-cap from over-cap and reject with SourceTooLarge.
Input redirect replaces 'base64 --' (no argv exposure at all for
leading-dash paths). Docker integration tests re-verified live.
The salvaged #52688 rasterizer shell-out predates the TUI subprocess
stdin= guard; a rasterizer that prompts on stdin could hang the tool
under prompt_toolkit. DEVNULL it.
- _normalize_to_supported_image: ensure cache/vision exists before writing
the converted PNG (fresh HERMES_HOME had no dir -> FileNotFoundError).
- resolver: SVG passes through as image/svg+xml instead of erroring; the
call sites rasterize to PNG via the salvaged normalize step (cairosvg /
svglib / rsvg-convert / inkscape, best-effort with actionable error).
- normalization offloaded via asyncio.to_thread at both call sites.
- tests: resolver pass-through + rasterization + no-converter error paths.
- AUTHOR_MAP: jonathan@mintrx.com -> JAlmanzarMint (PR #52688 salvage).
vision_analyze embedded SVG (and BMP/TIFF) tool-results into conversation
history with media_type image/svg+xml. Anthropic only accepts jpeg/png/
gif/webp, so the request fails with a non-retryable 400. Because the image
is baked into immutable history and re-sent every turn, the session is
permanently wedged on resume — retries re-send the same bad bytes.
Add _normalize_to_supported_image(): SVG is rasterized to PNG (best-effort
via cairosvg/svglib/rsvg-convert/inkscape), other non-supported raster
formats are re-encoded to PNG via Pillow, and if conversion is impossible
the tool returns an actionable error instead of a session-wedging payload.
Wired into both the native-vision fast path and the auxiliary-API path so
the whole bug class is covered, not just the one call site.
All 99 existing vision tests pass.
- resolve_image_source: bare cwd-relative filenames ('pic.png') resolve
again (main accepted them; the path-shape gate regressed them — review
by egilewski). Unknown explicit schemes (ftp://, s3://) still rejected.
- Local backend: nonexistent path now raises a clean 'image file not
found' instead of a misleading sandbox-fallback message.
- W4: remove the now-dead path-based _detect_image_mime_type (suffix-trust
SVG acceptance) so future callers can't reintroduce it.
- W3: SVG sources rejected with a dedicated actionable message + test.
- Polish: host read_bytes / temp-file write_bytes offloaded via
asyncio.to_thread (matches the container exec-read); unused
ResolveContext.cfg/extra_roots fields dropped; duplicate policy check
documented as intentional pre-flight short-circuit.
Salvage of #35362, evolved to also close the vision sandbox-escape
(GHSA-gpxw-6wxv-w3qq). The two were the same root cause — vision read image
bytes host-side while every other tool reads through the terminal backend —
so one resolver fixes both the delivery gaps and the escape.
Delivery (from #35362, re-authored against current main since the branch was
4140 commits stale and vision_tools.py had been rewritten on both sides):
- tools/image_source.py: one resolver for data:/http(s)/file/local/container
image sources, returning raw bytes through a single magic-byte-sniff +
50MB-ingest chokepoint. Fixes 'no image attached' / 'Invalid image source'
for every source type (#7571, #25118, #29643, #22328, #32709, #9077).
- tools/credential_files.py: from_agent_visible_cache_path, the container->host
cache reverse-map (inverse of the existing forward twin).
- tools/vision_tools.py: both vision sites route through the resolver with
task_id threaded from the handler; resolved bytes are materialized to a temp
file so main's evolved encode/resize/embed-cap pipeline is reused verbatim
(kept over the PR's older bytes-core resize to avoid touching browser_tool /
conversation_compression callers).
Security (fills #35362's deliberately-stubbed _within_allowed_roots seam):
- Under a non-local terminal backend the file tools are confined to the sandbox
(SECURITY.md 2.2), but vision read host-side — a prompt-injected
vision_analyze('/etc/passwd') exfiltrated host secrets, and read_file even
redirects the model to vision_analyze for image paths. The resolver now
enforces the same boundary: local backend reads any host path (chosen
posture); non-local backend host-reads ONLY the media caches under
HERMES_HOME (where the gateway/download media lives) and routes every other
path to an in-sandbox base64 exec-read — which reads the CONTAINER's file,
the same one 'cat' would, never the host's. Paths are resolve()-d so a
symlink can't escape a cache; fail-closed when no sandbox env exists.
This closes the escape AND delivers container-only images (#32709) with the
same mechanism.
Tests: unified resolver + confinement model (tests/tools/test_image_source.py,
incl. proof a non-cache host path under Docker yields container bytes not the
host secret); existing vision tests updated to the resolver boundary; Docker
integration test verified green against a real daemon (exec-read of a tmpfs
/workspace file, a root-owned mode-600 file, and the host-secret invariant).
Fixes GHSA-gpxw-6wxv-w3qq.

Both wired against features the iron-proxy author (@mslipper) confirmed on
PR #30179 — and both verified present in the pinned v0.39.0 source.
Header-auth providers (match_headers):
- New _HEADER_AUTH_PROVIDERS: Anthropic native (x-api-key), Azure OpenAI
(api-key on *.openai.azure.com / *.cognitiveservices / *.services.ai),
Gemini (x-goog-api-key + ?key= query param via match_query).
- TokenMapping grows match_headers + alias_env_names; per-provider header
sets flow into the secrets rules; mappings.json roundtrips them
(legacy files load with the Authorization default).
- GEMINI_API_KEY / GOOGLE_API_KEY collapse into ONE mapping (two
require-rules on the same host would reject each other); the sandbox
gets the token under both names, and the proxy child env mirrors the
alias into the canonical name when only the alias is set.
- Docker backend injects alias env names alongside canonical ones.
- The fail-closed tier is now empty, so fail_on_uncovered_providers and
discover_blocked_providers are deleted (dead toggle otherwise);
_NON_BEARER_PROVIDERS shrinks to genuinely-unswappable signature auth
(AWS SigV4, GCP service-account OAuth) — warn-only, as before.
Management API (hot reload):
- Generated proxy.yaml enables the v0.39 management listener: loopback
only at tunnel_port+2, bearer key from HERMES_IRON_PROXY_MGMT_KEY.
- Key minted at setup (management.token, 0600); start_proxy injects it
(v0.39 refuses to start when api_key_env is empty).
- hermes egress reload -> POST /v1/reload: re-reads proxy.yaml and
atomically swaps the pipeline; 422 leaves the running ruleset
untouched; actionable errors for not-running / pre-management config /
key mismatch. Secrets changes still require restart (daemon env is
read at spawn) — the CLI says so.
Validation: 218/218 unit+CLI+docker tests; 3/3 gated live E2E against the
real v0.39.0 binary (Authorization swap, x-api-key swap, live reload with
token rotation on the same pid). Docs updated.
On X11 a window's PID comes from the optional _NET_WM_PID property, so
cua-driver's list_windows legitimately returns pid: null for windows that
don't set it (desktop root, panels, override-redirect popups). capture()
and focus_app() coerced every entry via int(w["pid"]) inside a list
comprehension, so a single null-pid window raised TypeError and aborted
the whole enumeration before any screenshot — capture was impossible on
any X11 desktop with even one such window.
Route both ingestion sites through a new _ingest_windows() helper that
skips entries lacking a usable pid/window_id (uncapturable anyway) and
coerces the rest.
Adds tests/tools/test_computer_use_null_pid_windows.py covering the
helper's filtering/coercion and an end-to-end capture() regression that
reproduced the crash.

Follow-up to the salvaged SSH-tilde-cwd fix. The predicate
"backend == ssh and (cwd == ~ or cwd.startswith(~/))" was inlined at
each expanduser guard site, which is how the test simulator drifted from
production (it grew an SSH guard on a top-level-alias branch that has no
production counterpart).
- Add tools/terminal_tool._is_ssh_remote_tilde_cwd(backend, cwd) as the
single source of truth (case/whitespace-tolerant).
- Use it in _get_env_config and the gateway config bridge.
- Test simulator imports the real helper instead of re-implementing the
predicate; revert the phantom SSH guard on the top-level-alias branch
(production maps top-level cwd: to a plain env var, not TERMINAL_CWD via
an SSH-guarded path — that branch tested nothing real).
Follow-up to the salvaged #58000 fix.
- Extract _raise_if_non_interactive(lead) so the shared 'hermes mcp login'
next-step wording lives in one place across both OAuth boundaries
(_redirect_handler, _wait_for_callback), rather than two copy-pasted
inline raises. Boundary-specific lead sentences preserved verbatim, so
existing message-match tests stay green.
- Add a positive-control test asserting the guard does NOT over-fire on the
interactive path (valid/refreshable tokens keep working), satisfying an
explicit regression-coverage line from #57836.
A cached-but-unusable OAuth token (expired/revoked, or a refresh the IdP
rejects) makes the MCP SDK fall through to the authorization-code flow even
though build_oauth_auth's guard only checks token-file existence. In a
non-interactive context (systemd gateway, cron, background MCP discovery)
_redirect_handler then printed an auth URL / launched a browser flow no
operator can complete, and _wait_for_callback bound a localhost listener and
blocked for the full 300s timeout — gating gateway adapter startup and, on
retry, colliding on the callback port (OSError: [Errno 98] Address already
in use).
Re-check interactivity at the redirect/callback boundary and raise an
actionable OAuthNonInteractiveError before printing a URL, opening a browser,
or binding a listener. The guard holds regardless of whether a token file
exists (the point the token-file guard cannot cover), and only triggers on
the authorization-code path, so valid/refreshable tokens keep working
non-interactively. Both build_oauth_auth and MCPOAuthManager reuse these
handlers, so the sibling construction path is covered too.
Post-merge follow-ups + several review rounds + a hub-search rework, folded together.
Merge-scuff restores (a stale-base refactor had reverted two live-on-main fixes):
- gateway: SessionStore compression-tip healing + its regression test.
- desktop: messaging session/transcript polling in desktop-controller
(MESSAGING_POLL / ACTIVE_MESSAGING_SESSION_POLL, refreshMessagingSessions,
refreshActiveMessagingTranscript, the richer sameCronSignature) so inbound
platform traffic updates live again instead of freezing until manual refresh.
Profile-switch isolation (epoch/close/guard on every profile-scoped async):
- Hub store clears + in-flight runHubAction bails (and swallows the post-switch
404 instead of a phantom toast); hub preview/scan/search/sources profile-scoped.
- MCP: probe/auth epoch guards, dirty-draft reset, sidebar mutations blocked
until config resettles AND every persist re-checks the epoch post-await;
profilePending clears on config settle incl. error; logs re-key on profile.
- Model settings reload on switch and epoch-guard setModelAssignment /
saveMoaModels / API-key activation.
- Config draft resets + cancels its autosave on switch; skill editor/archive and
star-map node dialogs close on switch; openSkillEditor / star-map openEdit
discard stale fetches; tool-usage analytics loads are profile-guarded/keyed.
Correctness + UX:
- Unique per-skill action names for hub install AND uninstall; hub/catalog rows
flip only on a clean exit_code; catalog install polls the background bootstrap
to completion, reconciles the mcp.json draft (no dropped server), and fails
loudly on non-zero exit; MCP catalog query keyed by profile.
- /test reports needs-auth for anonymous auth:oauth servers; /auth snapshots +
restores tokens on a failed re-auth and clears the full 300s callback window.
- config-settings shows a retry on load failure; CodeEditor/JsonDocumentEditor
go read-only while saving so edits typed mid-save aren't dropped.
- Deep-link highlighter deletes its param only after a successful scroll.
- Restored the PageSearchShell trailing slot → Artifacts refresh button/spinner.
- /settings?tab=mcp redirect keeps server=.
Progressive hub search: fan out one query per backend-searchable source
(index-covered API sources stay unsearchable → no ~70-call GitHub re-hammer),
merge/dedupe by trust as each lands, per-source spinner overlaid on the dimmed
chip — results stream in without blocking on the slowest, no layout shift.
test(web): /api/skills list carries usage + provenance (CI contract).
Self-review follow-up. check_web_api_key() had a hand-rolled 'walk all
registered providers and probe each' fallback that duplicated the registry's
own availability-filtered resolvers (get_active_search_provider /
get_active_extract_provider, backed by _resolve()) — a second resolution path
that could diverge (the hand-rolled walk ignored capability, so a search-only
custom provider was handled inconsistently). Delegate to the registry's
resolvers so there is one authority for 'is a custom provider usable'.
Also: _get_backend()'s tail walk now probes provider.is_available() directly
instead of round-tripping through _is_backend_available(provider.name), which
redundantly re-did the registry get_provider() lookup on a provider object
already in hand. Both fallback loops guard is_available() against exceptions.
Documented that _LEGACY_WEB_BACKENDS intentionally includes 'xai' (probed via
has_xai_credentials, not a registered provider) while the registry's
_LEGACY_PREFERENCE excludes it, so the two built-in sets don't silently drift.
Plugin-registered web providers (registered via agent.web_search_registry)
were invisible to the tool-availability gate: _is_backend_available() was a
hardcoded env-var if-chain that returned False for any name outside the eight
built-in backends. Because check_web_api_key() is the check_fn for both
web_search and web_extract, a working custom provider with no built-in creds
left both tools filtered out of the toolset entirely.
Fix at the single chokepoint: _is_backend_available() now delegates non-legacy
backend names to the registered provider's is_available(), falling back to the
legacy built-in probes for known names and unregistered providers. Because
_get_backend(), _get_capability_backend(), and check_web_api_key() all resolve
availability through this one function, the fix cascades to every caller —
including the per-capability extract selection that produced a dead-end
'search-only' error (#32698). The two remaining hardcoded whitelist
early-returns (_get_backend, check_web_api_key) now also accept registered
names, and both walk registered providers as a final fallback so a custom
backend still resolves when no built-in has credentials.
Built-in backend priority is preserved unchanged: the registry is consulted
only for names outside _LEGACY_WEB_BACKENDS.

_handlers for vision_analyze and video_analyze read model name from
config.yaml (auxiliary.vision.model / auxiliary.video.model) before
falling back to AUXILIARY_VISION_MODEL / AUXILIARY_VIDEO_MODEL env
vars. Matches the existing config-first pattern for timeout and
temperature in the same file.
Fixes#53749
A user with tts.openai.model set to a direct-OpenAI model (e.g. tts-1-hd)
but no VOICE_TOOLS_OPENAI_KEY/OPENAI_API_KEY (or with tts.use_gateway)
routes TTS through the managed Nous audio gateway, which only proxies
gpt-4o-mini-tts. The request 400s with:
VALIDATION_ERROR: Unsupported managed OpenAI speech model
{'model': 'tts-1-hd', 'supportedModels': ['gpt-4o-mini-tts']}
_resolve_openai_audio_client_config now reports whether it resolved the
managed gateway; _generate_openai_tts coerces the model to a
managed-supported one (logging a warning that points at the direct-key
escape hatch) unless the user redirected base_url to their own endpoint.
Direct-key users keep their tts-1/tts-1-hd preference unchanged.

Remove acp_command and acp_args from the model-facing delegate_task schema and
dispatch paths. Child agents can still use ACP subprocess transport when it
comes from trusted delegation config or parent inheritance, but a model tool
call can no longer choose the command or arguments that reach child
construction.
This is salvageable because the risky boundary is model control over child ACP
transport, not ACP itself. The patch follows the maintainer direction from the
source discussion by preserving trusted ACP configuration and prior integration
work while removing the untrusted tool-call fields from both top-level and
per-task delegate inputs.
Reproduced on main by passing acp_command through delegate_task and observing it
reach _build_child_agent. Verified after the fix that model dispatch strips the
hidden top-level fields and per-task hidden fields are ignored before child
construction.

browser_cdp's frame_id (OOPIF) path returned early via
_browser_cdp_via_supervisor before _browser_cdp_private_guard ever ran,
unlike the stateless path a few lines below. A model that navigated a
cloud browser to a private/internal URL could still read page content
by passing frame_id, bypassing the same SSRF/private-page boundary
already enforced on Runtime.evaluate, Page.navigate, and other raw CDP
calls.
Apply the same guard call used by the stateless path before dispatching
to the supervisor, so both routing modes share one boundary.
A Cursor-style MCP manager inside Capabilities, plus the backend it needs.
- Server list with brand/favicon avatars + live status dot and a capability
summary (N tools, M prompts, K resources); Servers | Catalog views.
- Catalog: one-click install of Nous-approved servers with required-env prompts.
- GUI OAuth: Authenticate opens the system browser from the TTY-less backend and
verifies a token actually lands; header/API-key servers are never pushed down
OAuth; a dirty mcp.json can't drop a freshly-persisted auth field.
- Full-width mcp.json editor (ecosystem document format) + pinned stdio/agent
LogTail; probes cached 5m and keyed by (profile, config) so revisiting never
respawns the fleet or shows a stale probe.
- Whole-map persistence (PUT /api/mcp/servers) so deletes/toggles actually stick
(the generic /api/config deep-merge could not remove keys).
- perf: MCP probe/auth no longer hold the global skills lock, so a slow stdio
spawn can't stall every other request into a 15s timeout.
- per-tool include/exclude gating (lib/mcp-tool-filter) mirroring the CLI loader.
A Z.ai desktop user reported thinking reverting to medium after one turn,
burning ~200% of a week's credits in 4 days despite reasoning_effort: false
in config.yaml. Four compounding bugs:
- _session_info reported reasoning_effort "" for disabled reasoning,
indistinguishable from unset — the desktop adopted it after the first
turn, wiping its sticky "thinking off" pick so every later chat
reverted to the default effort.
- config.set key=reasoning always wrote agent.reasoning_effort to global
config.yaml, so every desktop model-menu selection (preset.effort ??
'medium') clobbered the user's configured value. Now session-scoped
like the messaging gateway's /reasoning, landing on
create_reasoning_override so lazily-built sessions keep it too.
- YAML `reasoning_effort: false`/`off`/`no` (boolean False) was coerced
to "" by every loader's `str(x or "")`, silently re-enabling thinking.
parse_reasoning_effort now treats False/"false"/"disabled" as
{"enabled": False}; loaders (tui gateway, gateway, cli, cron,
delegate) pass the raw value through. The desktop config reader also
crashed on the boolean (false.trim()), aborting voice/STT settings.
- The zai provider profile never sent thinking on the wire, and GLM-4.5+
defaults to thinking ON server-side — so disabling reasoning was a
silent no-op on direct Z.ai, the actual token burner. The profile now
emits extra_body.thinking {"type": "enabled"|"disabled"} for
thinking-capable GLM models, mirroring the DeepSeek profile.
Also: /new (session reset) now carries reasoning_config across the
rebuild like model_override; config.get reasoning prefers the session's
live value and maps a config False to "none"; Settings shows "Off"
instead of a blank select for hand-written false.
MSYS_NO_PATHCONV is honored by Git for Windows bash only. _find_bash's
final shutil.which fallback can return MSYS2-proper or Cygwin bash,
which ignore it and honor MSYS2_ARG_CONV_EXCL instead. Set both so argv
path conversion stays disabled regardless of which bash flavor spawns.
Also subsumes the cmd /c mangling in #56147.
Git Bash mangles native Windows command flags (/FO, /TN, /Create) into
bogus paths. Hermes terminal and background spawns now opt out by default
so tasklist, schtasks, and wmic work without manual prefixes.
Fixes#56700.
Follow-up to #56874, which added the Camofox private-page SSRF guard
(_camofox_current_page_private_url) but wired it only into the Camofox
eval path (_camofox_eval). The other Camofox content-read tools —
camofox_snapshot, camofox_get_images, and camofox_vision — still read the
current page's accessibility tree / images / screenshot without the
guard, so on a non-local Camofox backend they can return the content of
an intranet or cloud-metadata page (e.g. 169.254.169.254) that the
terminal itself can't reach.
Apply the same guard, gated on _eval_ssrf_guard_active (non-local
backend, not a local sidecar, allow_private_urls unset) and fail-open on
probe failure, matching the eval-path guard and the main-browser
snapshot/vision guards. camofox_back is intentionally not changed: its
target is unknown until navigation completes, and the subsequent content
read is already guarded.
Adds regression tests covering the three read tools blocking on a private
page, the public-page pass-through, and the guard-inactive no-probe path.
Three CLI reliability fixes:
1. Interrupt reliability: chat() only re-queued the user's interrupt
message when the turn result carried interrupted=True. When the agent
thread raced past its last interrupt check (or finished) before the
interrupt landed, the message was silently dropped — and the stale
_interrupt_requested flag left on the agent instantly aborted the
NEXT turn. Un-acknowledged interrupt messages are now re-queued as
the next turn and the stale flag is cleared (only when the agent
thread actually exited). The clarify-race path also parks the message
in _pending_input instead of dropping it.
2. Slow exit (5+ min): stdlib ThreadPoolExecutor workers are non-daemon
and joined unconditionally by concurrent.futures' atexit hook — even
after shutdown(wait=False). One wedged tool worker (abandoned after
interrupt/timeout) held the process open forever. Promoted
async_delegation's daemon executor to a shared tools/daemon_pool
module and adopted it in tool_executor (concurrent tool batches),
memory_manager (background sync), delegate_tool (child timeout wrapper
+ batch fan-out), and skills_hub (source fan-out). Added a 30s exit
watchdog (HERMES_EXIT_WATCHDOG_S) armed at _run_cleanup start as a
backstop for wedged cleanup steps.
3. Exit jank: after prompt_toolkit tears down the input/status bars the
terminal sat silent for the whole cleanup window, looking hung. Print
'Shutting down… (finalizing session)' immediately at exit start.
E2E: live PTY interrupt of a foreground 'sleep 120' terminal tool now
aborts in ~1s and the typed message runs as the next turn; wedged-worker
+ wedged-cleanup subprocess exits in 5.8s (watchdog) instead of hanging.
Salvage of #2863 by @aydnOktay, reimplemented against current main using the
existing utils.env_var_enabled / TRUTHY_STRINGS helper instead of per-site
tuple edits. Covers the 7 gateway/config.py env-flag sites that still rejected
'on' (WHATSAPP_ENABLED, SIGNAL_IGNORE_STORIES, MATRIX_ENCRYPTION,
API_SERVER_ENABLED, WEBHOOK_ENABLED, MSGRAPH_WEBHOOK_ENABLED,
BLUEBUBBLES_SEND_READ_RECEIPTS) plus HERMES_DESKTOP gating in
read_terminal/close_terminal. The PR's approval.py HERMES_YOLO_MODE portion is
already on main via is_truthy_value.
delegation.max_concurrent_children is now the single cap for both a
batch's parallelism and concurrent background delegation units.
- _get_max_async_children() delegates to _get_max_concurrent_children();
a leftover max_async_children key logs a one-time deprecation warning
- config v32→33 migration removes the stale key, folding a raised
max_async_children into max_concurrent_children (max wins, no lost
headroom)
- capacity error messages now point at max_concurrent_children
- pool-at-capacity sync fallback now attaches an explanatory note so
the model/user know why the call blocked instead of dispatching async
Previously users who raised max_concurrent_children (e.g. to 15) still
hit the invisible default-3 async cap: the 4th background delegate_task
silently ran inline, blocking the turn with no signal.
CLAUDE_CODE_OAUTH_TOKEN is set and owned by the user's Claude Code
install (subscription OAuth), not a Hermes-managed inference
credential — Claude subscription auth is not a working Hermes provider
path. Blocklisting it broke agent-spawned claude CLIs: with no token in
the child env, claude fell through to the shared macOS Keychain /
~/.claude/.credentials.json store and, on auth failure, cleared it —
logging the user out of their interactive Claude sessions and the
desktop app.
Exempt it from _HERMES_PROVIDER_ENV_BLOCKLIST (it arrives via the
anthropic registry entry, so discard explicitly with rationale).
ANTHROPIC_API_KEY / ANTHROPIC_TOKEN and every other provider credential
remain stripped, and the GHSA-rhgp-j443-p4rf fail-closed passthrough
guard is unchanged for everything still on the blocklist.
Fixes#55878
Extends the browser private-network eval guard to the Camofox backend.
On main, _browser_eval() returned early in Camofox mode before running the
shared private-URL literal pre-scan and before re-checking the page URL
after eval, leaving Camofox as a sibling backend that could execute
browser_console(expression=...) against private/internal targets.
- move the eval private-URL literal pre-scan before the Camofox early return
- add a Camofox current-page private-URL probe via the evaluate endpoint
- withhold Camofox eval results when the page is now private/internal
Follow-up to browser private-network hardening in #56173, #56526, #56664.
Salvage of #56764 by @rayjun (rayoo), cherry-picked to preserve authorship.
Vertex AI authenticates via OAuth2 (service-account JSON path / ADC), not
PROVIDER_REGISTRY, and VERTEX_CREDENTIALS_PATH is declared with
password=False (it's a path, not a bare key) under category="provider" —
a category the registry-derived blocklist loop never checks. Both it and
GOOGLE_APPLICATION_CREDENTIALS (the ADC fallback the adapter also reads)
fell through every existing blocklist source and leaked the on-disk
location of a GCP service-account key into every spawned subprocess
(terminal, codex/copilot app-server, browser workers) — the same leak
class already closed for every other provider's credentials in #53503.
Three connected changes that fix kanban notifications in multiplex_profile
gateways and enable event-driven agent collaboration:
1. Session profile propagation
- Add HERMES_SESSION_PROFILE ContextVar (session_context.py)
- Gateway stamps source.profile at dispatch time (run.py)
- _maybe_auto_subscribe reads profile from ContextVar instead of
os.environ which is unset in the gateway main process (kanban_tools.py)
2. Notifier profile-aware routing (kanban_watchers.py)
- Adapter selection: prefer _profile_adapters[sub.notifier_profile]
so each profile's bot delivers its own task notifications
- Relax profile skip-filter: process cross-profile subscriptions when
the gateway has an adapter for the owning profile
- Extend TERMINAL_KINDS with status/archived/unblocked
3. Creator agent wakeup on terminal events (kanban_watchers.py)
- After delivering completed/blocked/gave_up/crashed/timed_out
notifications, inject a synthetic MessageEvent into the creator's
session via adapter.handle_message to trigger their agent loop
- SessionSource built from subscription metadata — no session_store
lookup needed
Self-review follow-up on the salvaged approval-routing fix.
The initial adaptation re-read os.getenv("HERMES_YOLO_MODE") at session-build
time. That diverges from the repo's security invariant: HERMES_YOLO_MODE is
frozen into tools.approval._YOLO_MODE_FROZEN at import time precisely so a skill
running mid-process cannot set the env var and instantly flip the approval
bypass (a prompt-injection escalation path). A live re-read re-opened that hole
for the codex routing path.
- Add tools.approval.is_approval_bypass_active() — the canonical three-source
bypass check (frozen --yolo/HERMES_YOLO_MODE + session /yolo + approvals.mode
off) in one place. This is the 4th inline copy of that OR-chain (the three
sites in approval.py and tui_gateway/server.py:3121 all use the same idiom);
the helper is the shared chokepoint they can collapse onto.
- codex_runtime.py now calls is_approval_bypass_active() instead of the
hand-rolled mode-or-session check plus a runtime env re-read.
- Update the env-yolo test to patch _YOLO_MODE_FROZEN (the canonical test
pattern, e.g. tests/tools/test_yolo_mode.py) rather than setenv, which is
dead-on-arrival against the frozen constant.
Fail-closed default preserved on every branch; 28 integration + 77 session/yolo
tests pass; E2E confirms the real exec decision flips decline->accept only when
bypass is active.
Every other content-returning browser tool entry point
(browser_snapshot/vision/console/eval, and click/type/press via
_blocked_private_page_action) re-checks window.location.href against the
private/internal/cloud-metadata floor after the page could have changed --
because a redirect chain or client-side navigation can land on an address
the initial browser_navigate preflight never saw. browser_back was the one
navigation-triggering entry point missing this: it called
_run_browser_command(..., "back", []) and returned the resulting URL
straight to the model with no re-check.
On a cloud/CDP (non-local) backend, if browser history contains a
private/internal address (e.g. a prior redirect touched an internal host),
browser_back would navigate the live browser there and hand the URL back
to the model with no guard -- the exact class of gap the private-page
guard exists to close, just on the one entry point it hadn't reached yet.
Re-check happens after the navigation succeeds (not before, unlike
click/type/press) since it's the resulting page -- not the one being left
-- whose safety matters. A failed back navigation (no history) skips the
check entirely since nothing changed. Verified live: the new regression
test fails (returns the private URL instead of a blocked payload) on the
pre-fix code and passes after.
The Windows _quote_cwd_for_cd override only reached _wrap_command; the
snapshot bootstrap cd in init_session still used a bare shlex.quote(),
so on Windows the bootstrap cd failed and pwd -P captured the login
shell's dir instead of terminal.cwd. Route it through _quote_cwd_for_cd
too, and add -- for hyphen-safety to match _wrap_command.
On Windows machines with both Linux and Git for Windows installed,
_find_bash() called shutil.which('bash') before checking known
Git-for-Windows install paths. shutil.which() may return a
non-MSYS bash which does not understand Windows-style paths.
This caused all terminal commands to fail with exit code 126
because the cwd prefix (a Windows path) was rejected.
Reorder the search: check Git for Windows install locations
(ProgramFiles/Git/bin/bash.exe etc.) before falling back to
PATH lookup. This matches the intent of the surrounding code
(portable Git preferred, system Git preferred, then PATH as
last resort).

The model could pass `toolsets` (top-level and per-task) to delegate_task,
letting it choose which toolsets a subagent got. Toolset selection is a
capability-scoping decision the model should not control; subagents inherit
the parent's enabled toolsets, period.
- Remove `toolsets` from the delegate_task() signature, the registry handler,
the top-level + per-task JSON schema, and the live dispatch path
(run_agent._dispatch_delegate_task — this forwarded it on every model call).
- Single-task and per-task child builds now pass toolsets=None so
_build_child_agent resolves to pure parent inheritance.
- Drop the now-dead _SUBAGENT_TOOLSETS / _TOOLSET_LIST_STR schema-hint block.
- _build_child_agent keeps its internal toolsets param + intersection helpers
(internal API; fed the inherited value only).
- Tests: schema assertions flipped to assertNotIn; added a regression test
proving the dispatch path never forwards a smuggled model `toolsets`.
- Docs: update delegate_task signature refs in the autonomous-ai-agents skill.
Adds Vertex AI as a first-class provider for Gemini models via Vertex's
OpenAI-compatible endpoint. Vertex authenticates with short-lived OAuth2
access tokens (service-account JSON or ADC), not a static API key — the
missing piece behind the recurring requests (#13484, #12639, #56259).
- agent/vertex_adapter.py: OAuth2 token minting + refresh-on-expiry
(5-min margin), ADC->service-account fallback, global vs regional
endpoint URLs. Config precedence: env var > config.yaml > default.
- plugins/model-providers/vertex/: provider profile (auth_type=vertex),
reuses Gemini's extra_body.google.thinking_config translation.
- runtime_provider: vertex short-circuit BEFORE the credential pool so a
credentials-file path is never mistaken for a static API key; mints a
fresh token + computes base_url per resolve.
- run_agent + conversation_loop: _try_refresh_vertex_client_credentials()
re-mints the token and rebuilds the client on a mid-session 401, so a
long-lived gateway agent survives token expiry (~1h).
- auxiliary_client: vertex auth_type branch for side-LLM tasks.
- config.yaml: vertex.project_id / vertex.region (non-secret, bridged to
env); credential path stays in .env (VERTEX_CREDENTIALS_PATH).
- setup wizard + model picker: dedicated _model_flow_vertex; curated
google/gemini-* model list; --provider choices.
- pricing/metadata: Vertex prices off the gemini docs snapshot; endpoint
host auto-maps to the vertex provider (no probe spam).
- lazy_deps + pyproject [vertex] extra: google-auth, opt-in only.
- docs: guides/google-vertex.md + providers page; tests for adapter +
runtime resolution.
Salvages and modernizes #8427 by @slawt onto current main: rewired from
the legacy PROVIDER_REGISTRY path to the provider-profile architecture,
moved non-secret config out of .env into config.yaml, and added the
per-turn 401 token-refresh the original lacked.
The patch tool's strategy 7 (unicode_normalized) matches ASCII old_string
against a file containing real Unicode (em-dashes, smart quotes, ellipsis,
non-breaking spaces). Writing new_string verbatim silently replaced the
file's Unicode with the LLM's ASCII equivalents.
_preserve_unicode_in_replacement() diffs old_string->new_string and applies
only the actual edits to the file's original Unicode text, preserving
unchanged characters.
Salvaged from #50540 by @aj-nt. Only the Unicode-preservation half is
carried over; the write_file line-number-strip half was dropped (the
existing _looks_like_read_file_line_numbered_content reject guard already
covers its target case, and the strip's looser threshold risks silently
mutating legitimate pipe-delimited content).
