Second, deeper pass over tools/gateway/hermes_cli plus first pass over
the trees wave 1 missed (acp, acp_adapter, skills, computer_use, docker,
dashboard, conformance, monitoring, secret_sources, hermes_state,
providers). Same rubric as wave 1 (AGENTS.md test policy); security,
alternation/caching invariants, issue-number regressions, and E2E kept.
Real test-quality fixes found and rooted out along the way:
- tests/tools/test_command_guards.py made real auxiliary-LLM HTTPS calls
(DEFAULT_CONFIG smart-approval leaked in) — pinned approval
mode=manual via autouse fixture: 17.4s → 0.4s.
- test_model_switch_custom_providers.py / test_user_providers_model_switch.py
silently probed live provider catalogs (~2s/test) — stubbed
cached_provider_model_ids/provider_model_ids/fetch_api_models.
- test_telegram_noise_filter.py: 15-platform copy-paste matrix over
shared gateway.run logic → 3 representative platforms (55s → 3.9s).
- test_gateway_shutdown.py: stop()'s 5s interrupt-deadline loop spun on
MagicMock agents — interrupt.side_effect now clears _running_agents
(22s → 1.0s).
- test_gateway_inactivity_timeout.py poll-harness timings shrunk 3-5x
(24s → 1.1s); test_mcp_stability.py backoff/SIGTERM-grace sleeps
patched (15.4s → 2.5s); test_async_delegation.py negative-drain wait
5s → 0.5s.
- test_telegram_init_deadline.py: loop-block margin restored to 1.0s
with rationale comment — the watchdog-dump assertion needs the loop
blocked well past deadline+grace under parallel load (flaked once in
the 40-worker verification run at a 0.2s margin).
Verification: full hermetic suite via scripts/run_tests.sh —
2,438 files, 21,718 tests passed, 0 failed, 293.9s wall.
Suite totals vs original baseline: 46,820 → 19,757 test functions
(−57.8%), wall 583.5s → 293.9s (−50%), subprocess CPU 13,564s → 11,623s.
`resolve_openai_audio_api_key()` reads the key that authenticates the audio
client straight from the process environment:
return (
os.getenv("VOICE_TOOLS_OPENAI_KEY", "")
or os.getenv("OPENAI_API_KEY", "")
).strip()
That value is not advisory. It flows through
`_resolve_openai_audio_client_config()` into `OpenAIClient(api_key=...)` for
TTS, and through `transcription_tools` for voice-note STT — both on the
per-turn tool path, inside the profile secret scope the gateway installs.
`agent/vertex_adapter` states the contract this breaks:
in a multiplex gateway serving several profiles from one process,
os.environ reflects whichever profile's .env happened to be loaded at
boot, not the profile the current turn belongs to. Reading it directly
here would let one profile mint tokens from — and get billed against —
a different profile's service-account file.
Reproduced with the real resolver, multiplexing on and profile A's scope
installed:
scope-aware get_secret -> sk-PROFILE-A-key
voice/STT resolver -> sk-PROFILE-B-key
So profile A's spoken reply and its users' voice notes are sent to OpenAI on
profile B's account, and billed there.
Route both reads through `agent.secret_scope.get_secret`, the same fix already
merged for the WeChat send path (#59662) and pending for QQ (#60420) — neither
covers the audio credential family. Under multiplexing the scope stays
authoritative, so a scope miss now yields no key instead of borrowing another
profile's; with multiplexing off `get_secret` falls through to `os.environ`
exactly as before, so single-profile deployments are untouched. The
VOICE_TOOLS_OPENAI_KEY > OPENAI_API_KEY precedence is unchanged.
Deliberately narrow: `fal_key_is_configured()` and
`has_direct_modal_credentials()` in this file are presence checks, not
authentication, and the former is already being reworked in open PR #20929.
tests/tools/test_tool_backend_helpers.py: the scope wins over another
profile's `os.environ`; a scope miss does not borrow another profile's key;
voice-key precedence holds inside a scope; and a control proves the
single-profile path still reads `os.environ`. The three isolation tests fail
on main; the control passes there. 320 passed across the helper, secret-scope,
and consumer suites (the fluctuating voice_mode/voice_cli failures are
pre-existing PulseAudio/ordering artifacts — the differing test passes 3/3 in
isolation on both main and this branch).
When HOME=/root (Docker containers) and the process runs as unprivileged
user (hermes, uid 10000), Path.home() / '.modal.toml' raises PermissionError
because /root/ is inaccessible. This crashes the dashboard /api/skills endpoint.
Catch PermissionError/OSError and treat as 'no config file'. Env vars still
take priority (tested).
Fixes#33525
Replace the HERMES_ENABLE_NOUS_MANAGED_TOOLS env-var feature flag with
subscription-based detection. The Tool Gateway is now available to any
paid Nous subscriber without needing a hidden env var.
Core changes:
- managed_nous_tools_enabled() checks get_nous_auth_status() +
check_nous_free_tier() instead of an env var
- New use_gateway config flag per tool section (web, tts, browser,
image_gen) records explicit user opt-in and overrides direct API
keys at runtime
- New prefers_gateway(section) shared helper in tool_backend_helpers.py
used by all 4 tool runtimes (web, tts, image gen, browser)
UX flow:
- hermes model: after Nous login/model selection, shows a curses
prompt listing all gateway-eligible tools with current status.
User chooses to enable all, enable only unconfigured tools, or skip.
Defaults to Enable for new users, Skip when direct keys exist.
- hermes tools: provider selection now manages use_gateway flag —
selecting Nous Subscription sets it, selecting any other provider
clears it
- hermes status: renamed section to Nous Tool Gateway, added
free-tier upgrade nudge for logged-in free users
- curses_radiolist: new description parameter for multi-line context
that survives the screen clear
Runtime behavior:
- Each tool runtime (web_tools, tts_tool, image_generation_tool,
browser_use) checks prefers_gateway() before falling back to
direct env-var credentials
- get_nous_subscription_features() respects use_gateway flags,
suppressing direct credential detection when the user opted in
Removed:
- HERMES_ENABLE_NOUS_MANAGED_TOOLS env var and all references
- apply_nous_provider_defaults() silent TTS auto-set
- get_nous_subscription_explainer_lines() static text
- Override env var warnings (use_gateway handles this properly now)
Cover all public functions with 50 test cases:
- managed_nous_tools_enabled() feature flag toggling
- normalize_browser_cloud_provider() coercion and defaults
- coerce_modal_mode() / normalize_modal_mode() validation
- has_direct_modal_credentials() env vars and config file detection
- resolve_modal_backend_state() full backend selection matrix
- resolve_openai_audio_api_key() priority chain and edge cases
