7b5a18817 migrated the sibling slug sites to custom_provider_slug, which
keeps a keyed providers: entry's config key as its durable identity. It
covered find_custom_provider_identity_by_model; canonical_custom_identity's
third recovery source - the configured-provider fallback - still built
f"custom:{normalized}" out of whatever string the caller happened to hold.
_get_named_custom_provider matches on either spelling, so a display name
that differs from its config key matches the entry and then heals to
custom:<display-name>. That is a second identity for one endpoint: the
endpoint- and model-based sources of the same function return
custom:<config-key>, and so does everything that persists or restores a
session's provider override. canonical_custom_identity exists precisely to
make a bare "custom" routable again, and tui_gateway calls it on the
session-persist, resume and recovery paths - so the divergence lands in
stored session identity.
Re-resolve through the endpoint the matched entry owns, reusing the
function's own URL-based canonicaliser rather than duplicating the match
logic. Legacy unkeyed custom_providers: entries keep their name identity,
and an unconfigured candidate still returns None.
_resolve_explicit_runtime's generic-provider branch accepted model_cfg's
persisted api_mode unconditionally, letting a stale mode from a previous
provider (e.g. anthropic_messages) leak into a newly-switched provider
(e.g. gemini) and break the transport. Reuse the existing
_provider_supports_explicit_api_mode guard, already used by the copilot
and named-custom-provider resolution paths for exactly this case, so the
persisted mode is only honored when model_cfg's provider matches the one
being resolved.
Closes#74318
The P1 from the enterprise data-residency report: with
model.base_url=https://us.api.openai.com/v1, every tool-calling turn 400'd
('Function tools with reasoning_effort are not supported ... use
/v1/responses') because the runtime resolvers hardcoded
api_mode=chat_completions and consulted URL detection only. openai-api
declares codex_responses in its overlay; the declaration was never
consulted, so any OpenAI host that wasn't literally api.openai.com landed
on the wrong wire protocol.
New _fallback_api_mode(provider, base_url, model): URL detection first
(host-mandated wire shapes keep priority), then
providers.determine_api_mode() (the provider's declared transport), then
chat_completions only for genuinely unknown providers. All three runtime
fallback sites route through it: the pool-entry path, the explicit-runtime
path, and the API-key-provider path, so the lanes cannot drift apart.
Blast radius beyond openai-api: minimax, minimax-cn, and copilot-acp were
the other overlays whose declared non-chat transport fell through to
chat_completions on the same paths (same latent bug class). openrouter is
unaffected (declares openai_chat). _detect_api_mode_for_url also now uses
the shared official-host predicate, so regional hosts detect as
codex_responses on the direct-URL lane too.
find_custom_provider_identity_by_model (runtime_provider.py:895,908) and
acp_adapter/server.py:149 still used the old f"custom:{_normalize_custom_provider_name(...)}"
pattern while the rest of the codebase migrated to custom_provider_slug.
For keyed providers whose display name differs from their config key, the
model-based reverse lookup would return custom:<display-name> instead of
the stable custom:<provider_key> identity every other code path returns.

Use providers keys as the canonical custom-provider identity while accepting legacy bare keys, display-name slugs, bare custom fallback, and doubled custom prefixes across resolution, pickers, doctor, and runtime reverse lookup.

Local-model users paid a fresh probe waterfall on EVERY CLI cold start
inside AIAgent.__init__: detect_local_server_type (up to 4 HTTP GETs,
2s timeout each on a hung server) + /api/show (3s timeout). The
existing caches were in-process only, so back-to-back invocations
(chat -q, cron ticks, subagents) re-paid the network every time.
- New 300s-TTL disk L2 at HERMES_HOME/cache/local_endpoint_probes.json
for detect_local_server_type verdicts and query_ollama_num_ctx
results. Only SUCCESSFUL probes persist (a down server never pins a
negative verdict); stale entries pruned on write; corrupted cache
degrades to a miss; atomic writes. 300s is strictly fresher than the
1h in-process TTL that already accepts server-swap staleness.
- models.dev fetch timeout 15 -> (5, 10) connect/read tuple: a
blackholed connect stalled the first-turn critical path 15s; now
fails in 5s (matches the OpenRouter fetch convention, #46620).
- _auto_detect_local_model timeout 5 -> (2, 3): runs inside
_get_model_config() at startup against a LOCAL endpoint; a hung local
server cost 5s before the banner.
E2E (real HTTP server, two fresh subprocesses, isolated HERMES_HOME):
proc1 = 2 HTTP hits, proc2 = 0 HTTP hits, identical results
(ollama/131072), probe wall 74.5 -> 35.5 ms. 222 targeted tests green
incl. 9 new disk-L2 contract tests.
A session pinned to a named custom provider could silently reroute to the
user's default provider on resume/rebuild. Session rows persist the RESOLVED
provider — bare "custom" for every named providers:/custom_providers: entry —
and when no base_url survived in model_config, the existing heal
(canonical_custom_identity) had only the config.model.provider fallback left.
For users whose global default is a BUILT-IN provider (e.g. nous) that tier
cannot fire, so the bare provider was dropped, resume fell back to the default
provider with the session's custom model name, and the default endpoint 404'd
with "Model '<x>' not found. The requested model does not exist in our
configuration or OpenRouter catalog." Re-selecting via /model fixed it until
the next resume — the reported symptom.
Add a model-name recovery tier between the base_url reverse-lookup and the
config fallback: find_custom_provider_identity_by_model() maps the stored
model back to the entry that serves it (model/default_model/models catalog,
dict and legacy list shapes). The session row always stores the model, so the
entry identity survives even when the row has no base_url AND the global
default points elsewhere.
All five bare-custom heal sites in tui_gateway/server.py now pass the model:
_ensure_session_db_row, _stored_session_runtime_overrides,
_runtime_model_config, _make_agent, and _model_picker_context.
Removes Homebrew and PyPI wheel/sdist as Hermes distribution paths while
preserving the supported source, Docker, and Nix workflows.
Changes:
- Removes the Homebrew formula, PyPI publish workflow, sdist manifest
(MANIFEST.in), and wheel/sdist release-attachment logic from scripts/release.py.
- Keeps setuptools metadata and entry points required by editable installs
and Docker/Nix builds, but adds a setup.py guard that rejects wheel/sdist
builds outside a sealed Nix derivation (HERMES_NIX_BUILD=1).
- Removes pip/Homebrew install detection, PyPI update checks, the pip
self-update path, the deprecation-banner state, the postinstall subcommand,
wheel data-directory fallbacks in agent/i18n.py and hermes_constants.py,
and the ACP Registry manifest/version-lockstep release logic.
- Adds /nix/store/ path detection so `nix run` / `nix profile install`
installs (which don't set HERMES_MANAGED) are correctly identified as
"nix" rather than falling through to "git"/"unknown".
- Retired install-method values ("pip", "homebrew") in existing
.install_method stamps (both code-scoped and home-scoped) are ignored by
the allowlist reader and fall through to "unknown" instead of resurrecting
a retired enum value.
- Updates Nix packaging to ship bare runtime data (locales, optional-mcps)
through store symlinks and wrapper env vars instead of wheel data-files.
- Removes the ACP Registry manifest/icon and their version-lockstep tests.
- Deletes or rewrites packaging, pip-update, Homebrew, and ACP Registry
tests; adds parametrized coverage for the packaging build guard covering
BOTH sdist and wheel paths (the guards live in separate cmdclass entries
— a passing sdist test proves nothing about the wheel path).
- Updates installation/platform documentation and related user-facing copy.
- Adjusts the supply-chain scan so deleted install-hook files do not trigger
a finding, while additions or modifications still require the existing
ci-reviewed label gate.
Supported installation paths (unchanged):
- git installer (install.sh)
- Docker
- Nix/NixOS
- editable development installs (uv sync, uv pip install -e ., pip install -e .)
The first commit's gate sat inside ``_get_named_custom_provider`` —
which only handles user-defined custom blocks. Built-in provider names
(``openai`` / ``anthropic`` / ``openrouter`` / ``gemini`` / ...) have
their own resolution paths in ``resolve_runtime_provider`` (pool /
explicit / generic / ``resolve_provider``) and bypass that gate.
So a user who flipped ``providers.openrouter.enabled: false`` would
still see OpenRouter resolved when something explicitly requested it
(e.g. a fallback chain entry). That defeats the point of the flag.
This commit moves the gate one level up: right after
``requested_provider`` is computed, before any custom / built-in /
Azure short-circuit. It now raises a typed ``ValueError`` referencing
the YAML path, so callers can recognise it and advance to the next
fallback instead of silently using a disabled provider.
3 new tests cover:
* disabled custom provider raises
* disabled built-in provider raises
* enabled provider doesn't hit the gate
All 20 tests in the providers suite pass.
A ``providers.<name>`` block in ``config.yaml`` can now opt out of being
listed anywhere by setting ``enabled: false`` — without removing the
block, so re-enabling it stays a one-line edit. Missing or ``true`` keeps
the previous behaviour (enabled), so this is fully backwards-compatible.
The flag is honoured in four places:
* ``hermes_cli/model_switch.py`` — model-override validation (the
allow-list that the picker consults to accept a non-public model id)
and the picker's own endpoint iteration. A disabled provider no longer
appears as a row and its models can't be silently accepted via
override.
* ``hermes_cli/runtime_provider.py`` — the runtime resolver skips
disabled blocks, so an explicit ``--provider X`` against a disabled
entry fails fast instead of using stale base_url / api_key from the
ignored block.
* ``hermes_cli/doctor.py`` — the doctor's "configured providers" set
excludes disabled entries, so health checks don't flag missing API
keys for providers the user has turned off.
Motivation: when a user has 20+ providers wired up in ``config.yaml``
(many of them only used occasionally) the picker becomes noisy and the
runtime resolver may pick a suboptimal one on ambiguous --provider names.
There's currently no way to hide a provider short of deleting its block
— which loses the api_key + base_url + custom routing config the user
spent time wiring. ``enabled: false`` lets them keep the config but get
it out of the way.
The helper ``is_provider_enabled()`` in ``hermes_cli/config.py``
centralises the gate (and accepts YAML-stringified booleans like
``"false"`` for hand-edited configs). 17 unit tests cover the defaults
and edge cases.
A follow-up PR can wire ``hermes provider enable/disable <name>`` and a
dashboard toggle on top of this primitive — they reduce to mutating the
flag.
Three fixes for the Bedrock Claude path:
1. Streaming fallback: When AnthropicBedrock SDK raises 'Unexpected event
order' (SDK misparses Bedrock error events as message_start), auto-switch
to native Converse API for the rest of the session instead of failing
after 3 retries.
2. Image base64 decode (#33317): data URL payloads were passed as base64
strings to source.bytes, but boto3 re-encodes at the wire layer. Now
decoded to raw bytes before passing to Converse API.
3. Bearer token routing (#28156): Users with AWS_BEARER_TOKEN_BEDROCK are
now routed through Converse API regardless of model, since the
AnthropicBedrock SDK only supports SigV4 signing.
3 new tests. 121 bedrock_adapter tests passing.
Retain the provider-boundary core of #52799 while reusing the pool reload and handoff paths already landed in #53591 and #62417.

OpenCode Go serves minimax/qwen via Anthropic Messages (base URL without
/v1 — the SDK appends /v1/messages) and glm/kimi/deepseek/mimo via OpenAI
chat completions (base URL WITH /v1). The runtime stripped /v1 for
anthropic-routed models, and the TUI/desktop + gateway persisted that
stripped URL to model.base_url. Every later chat_completions model then
POSTed to https://opencode.ai/zen/go/chat/completions — a 404 (the
marketing site). Result: only minimax worked; glm/deepseek/kimi all 404ed.
- New normalize_opencode_base_url(): symmetric /v1 normalization —
strip for anthropic_messages, re-append for chat_completions /
codex_responses on opencode.ai hosts (heals persisted stripped URLs;
custom proxy overrides untouched)
- Applied at all three former one-way strip sites (resolve_runtime_provider
x2, switch_model)
- opencode_model_api_mode: all Qwen models on Go AND Zen now route via
/v1/messages per current published endpoint tables (previously only
qwen3.7-max on Go — qwen3.6-plus etc. would 404 the same way)
- Catalog refresh: Go gains deepseek-v4-pro/flash, glm-5.2,
kimi-k2.7-code, minimax-m3, qwen3.7-plus; Zen gains glm-5.2,
kimi-k2.7-code, minimax-m3, qwen3.7-plus
Reported by IndieSuperhuman on X: opencode-go 404s for any model other
than minimax.
Follow-up to @helix4u's #57336 salvage. Two review findings:
- W1: model-picker grouped custom-provider rows by
(api_url, credential, api_mode) but NOT extra_headers. Entries sharing a
URL+credential+api_mode yet declaring different headers (e.g. per-tenant
routing behind one proxy) collapsed into one row and probed /models with
whichever header set was seen first (order-dependent). Fold a canonical
header identity into group_key so distinct header-authed endpoints stay
separate; drops the now-dead first-non-empty merge branch.
- W2: the extra_headers stringify+None-filter comprehension existed in 5
copies (config.py x2, runtime_provider.py, model_switch.py, models.py).
Extract one shared hermes_cli.config.normalize_extra_headers primitive;
all sites now call it.
Tests: +normalize_extra_headers unit tests, +regression test proving two
same-endpoint entries with different headers stay distinct and each probes
with its own headers. 223 targeted tests pass; ruff clean.
Named providers / custom_providers entries in config.yaml now accept an
extra_headers dict scoped to that endpoint — for reverse proxies, API
gateways, and custom auth schemes (e.g. Cloudflare Access service tokens).
- hermes_cli/config.py: normalize extra_headers on provider entries
(_normalize_custom_provider_entry + providers-dict translation), add
get_custom_provider_extra_headers /
apply_custom_provider_extra_headers_to_client_kwargs helpers keyed on
base_url (case/trailing-slash insensitive, no substring bypass —
mirrors the TLS helpers)
- hermes_cli/runtime_provider.py: surface extra_headers in the resolved
runtime for named custom providers (providers dict, legacy
custom_providers list, and the credential-pool path)
- run_agent.py / agent/agent_init.py: merge per-provider extra_headers
onto the OpenAI client default_headers at construction and on every
_apply_client_headers_for_base_url re-application (credential swaps,
rebuilds), most-specific level wins; OpenAI-wire only (native
Anthropic/Bedrock scoped out)
- agent/auxiliary_client.py: accept model.extra_headers as an alias of
model.default_headers for the global variant
- cli-config.yaml.example: documented commented example
- Header values are treated as secrets and never logged

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.
`_detect_api_mode_for_url` previously returned `None` for the bare
`api.anthropic.com` host, causing every URL-fallback path
(custom_providers, direct-alias, the api-key fallback inside
`resolve_runtime_provider`) to default to `chat_completions` for
native Anthropic — which routes requests to the OpenAI-compat
`/chat/completions` shim instead of the native `/v1/messages`
endpoint.
Pro/Max OAuth subscriptions are only billed against the native
Messages API; the shim bills against a separate "extra usage" pool
that is empty by default, so a freshly authorized Pro/Max credential
400s with "You're out of extra usage" the moment it's used — even
on an account that has consumed nothing for the current cycle.
Brings the helper in line with `hermes_cli.providers.determine_api_mode`
which already mapped `api.anthropic.com` to `anthropic_messages`.
Upstream #52270 added `_nous_inference_env_override()` but wired it into
only `resolve_nous_runtime_credentials`. Three sibling resolution paths
still ignored the override, so a self-hosted Nous inference endpoint set
via `NOUS_INFERENCE_BASE_URL` was silently dropped whenever credentials
arrived through any of them:
- the credential-pool path (`_resolve_runtime_from_pool_entry`)
- the explicit-provider path (`_resolve_explicit_runtime`)
- the auxiliary side-LLM client (`_pool_runtime_base_url`)
Route all three through the same auth-layer reader so every
`NOUS_INFERENCE_BASE_URL` read shares one normalization path
(trailing-slash stripping, blank -> empty) and the documented
trusted-bypass intent stays in one place. The override is live-only: it
wins for the base URL returned this run but is never persisted to
auth.json or the credential pool, so an ephemeral dev/staging value
cannot poison durable auth state.

Generic provider:custom relays were force-routed to the OpenAI Responses
API whenever the model matched gpt-5*, and a stale persisted
model.api_mode=codex_responses survived /reset and upgrades. Some
OpenAI-compatible relays do not implement Responses semantics, which
surfaced as malformed function_call.name replay errors in gateway sessions.
- runtime_provider: route custom-provider api_mode through
_resolve_plain_custom_api_mode(), which drops a stale codex_responses
unless the URL is direct OpenAI/xAI
- run_agent: _provider_model_requires_responses_api returns False for
custom; direct api.openai.com / api.x.ai URLs still upgrade via
_is_direct_openai_url() / URL detection
- regression coverage for plain relays vs direct OpenAI/xAI URLs

A config left with `provider: anthropic` but a leftover
`base_url: https://openrouter.ai/api/v1` (e.g. after a provider switch)
would route Anthropic OAuth/setup-token traffic to OpenRouter and 404.
Add `_anthropic_base_url_override_ok()` and gate the three native-Anthropic
resolution branches (pool, explicit, native) on it. The guard honors a
configured `model.base_url` only when it plausibly speaks the Anthropic
Messages protocol — official `*.anthropic.com` / `*.claude.com` hosts, Azure
Foundry endpoints, and `/anthropic`-suffixed or Kimi `/coding` proxies — and
falls back to `https://api.anthropic.com` otherwise. Aggregator URLs like
openrouter.ai / api.openai.com are treated as stale.
Reconstructed from @clovericbot's PR #3661 onto current main: the original
patched one branch with an anthropic-only allow-list, which would have broken
Azure-via-anthropic; widened to all three sites and made Azure/proxy-safe.
When config.yaml has `provider: auto` and a non-cloud `base_url` (e.g. Ollama
at localhost:11434), requests were silently sent to https://api.anthropic.com
whenever ANTHROPIC_API_KEY was present in the environment, ignoring the
configured local endpoint and returning HTTP 401 / "credit balance too low".
Root cause: resolve_provider("auto") scans env vars and returns "anthropic"
when ANTHROPIC_API_KEY is set, before config.model.base_url is ever consulted.
In resolve_runtime_provider(), before calling resolve_provider(), short-circuit
to the OpenAI-compatible resolver when no explicit creds were passed, provider
is "auto"/unset, and a non-cloud base_url is configured. Well-known cloud roots
(openrouter.ai, anthropic.com, openai.com) are matched on HOST (not substring)
so look-alike hosts can't evade the bypass and leak a cloud credential.

* feat(moa): expose MoA presets as selectable virtual models
Reconstructed onto current main (PR #46081's base had diverged with no common
ancestor, marking the PR dirty so CI never dispatched). MoA is now a virtual
provider: each named preset is a selectable model under provider 'moa', and the
preset's aggregator is the acting model that answers and calls tools.
Reference models fan out in parallel via a bounded ThreadPoolExecutor (the same
batch pattern delegate_task uses) — all references dispatched at once, collected
when every one finishes, then handed to the aggregator. Output order is
preserved, failures and the MoA-recursion guard stay isolated per reference.
- Removed the old mixture_of_agents model tool and moa toolset.
- Added moa as a virtual provider in the provider/model inventory.
- /moa is shortcut behavior over model selection (default preset / named preset
/ one-shot prompt).
- Dashboard + Desktop manage named presets; presets appear in model pickers.
- Parallel reference fan-out in agent/moa_loop.py with regression test.
* fix(moa): thread moa_config through _run_agent to _run_agent_inner
The reconstructed gateway MoA wiring declared moa_config on _run_agent (the
profile-scoping wrapper) and used it inside _run_agent_inner, but the wrapper
never forwarded it — _run_agent_inner had no such parameter, so the runtime hit
NameError: name 'moa_config' is not defined on the compression-failure session
sync path. Add moa_config to _run_agent_inner's signature and forward it from
both wrapper call sites (multiplex and non-multiplex). Caught by
tests/gateway/test_compression_failure_session_sync.py on CI shard test(4).
* fix(moa): classify moa as a virtual provider in the catalog
The moa virtual provider has no PROVIDER_REGISTRY/ProviderProfile entry, so
provider_catalog() fell through to the default auth_type="api_key" with no
env vars — tripping two catalog invariants:
- test_provider_catalog: api_key providers must expose a credential env var
- test_provider_parity: every hermes-model provider must be desktop-configurable
moa already declares auth_type="virtual" in HERMES_OVERLAYS; consult that
overlay as an auth_type fallback so the catalog reports moa as virtual (no real
credential, no network endpoint). Exempt virtual providers from the desktop
parity union check the same way 'custom' is exempt — derived from the catalog,
not a hardcoded slug, so future virtual providers are covered too.
* feat(providers): remove google-gemini-cli + google-antigravity OAuth providers
Google now actively bans accounts for third-party tools that piggyback on
Gemini CLI / Antigravity / Code Assist OAuth, and because abuse prevention
sits at a backend layer the ban can extend to the entire Google account
(Gmail/Drive), with a second violation being permanent.
Ref: https://github.com/google-gemini/gemini-cli/discussions/20632
Removes both OAuth inference providers entirely (modules, provider profiles,
auth/runtime/config/models wiring, the /gquota Code Assist quota command,
the antigravity-cli optional skill, desktop + docs surface in en + zh-Hans).
The API-key 'gemini' provider (GOOGLE_API_KEY/GEMINI_API_KEY against
generativelanguage.googleapis.com) is unaffected and stays fully supported.
* fix(skills): keep the antigravity-cli skill — only the OAuth provider is removed
The antigravity-cli optional skill orchestrates the external `agy` binary as
a coding-agent tool via the terminal tool — it does NOT wrap Hermes inference
through the banned google-antigravity OAuth provider, so it carries none of
the account-ban risk that motivated removing that provider. Restore the skill,
its docs page, the sidebar entry, and the optional-skills catalog row. The
google-antigravity / google-gemini-cli inference providers stay fully removed.
The credential gate. When multiplexing is active, a profile's secrets resolve
from a context-local scope, never the process-global os.environ (which in a
multiplexer may hold another profile's keys, and is inherited by every
subprocess spawned with env=dict(os.environ)).
- agent/secret_scope.py: get_secret() backed by a secret-scope contextvar.
FAIL-CLOSED: when multiplex is active and no scope is installed, an unscoped
read RAISES UnscopedSecretError instead of falling back to os.environ — a
missed/new call site crashes loudly at that line rather than leaking a
cross-profile value. Genuinely-global vars (HERMES_*, PATH, kanban paths,
…) keep reading os.environ via an allowlist. load_env_file/build_profile_
secret_scope parse a profile .env into an isolated dict WITHOUT mutating
os.environ. Off by default => transparent os.getenv behavior.
- hermes_cli/runtime_provider.py: all credential/provider/base-url reads go
through _getenv -> get_secret.
- agent/credential_pool.py: env fallbacks route through get_secret (the
~/.hermes/.env-first preference is preserved and already profile-correct via
the home override).
- tools/mcp_tool.py: MCP config interpolation resolves through
get_secret, so a server's picks up the routed profile's value.
- gateway/run.py: set_multiplex_active() at GatewayRunner init; per-turn .env
reload is a no-op for credentials in multiplex mode (secrets come from the
scope, not global env); _profile_runtime_scope context manager combines the
HERMES_HOME override + secret scope; _run_agent wraps _run_agent_inner in
that scope (resolved via _resolve_profile_home_for_source) when multiplexing.
Propagates into the agent worker thread for free via the existing
copy_context() in _run_in_executor_with_context.
Tests: 13 unit (fail-closed, scope isolation, global allowlist, .env parsing
without environ mutation) + 7 E2E (runtime_provider + MCP interpolation prove
two profiles isolated, unscoped read raises, globals still read environ).
* Port from cline/cline#11514: encourage parallel tool calls
Add a universal system-prompt guidance block telling the model to batch
independent tool calls (reads, searches, web fetches, read-only commands)
into a single assistant turn instead of one call per turn. The runtime
already executes independent batches concurrently (read-only tools always;
non-overlapping path-scoped file ops); the open-source system prompt had
nothing steering the model to PRODUCE the batch. Fewer round-trips means
less resent context, which compounds over a long conversation.
- prompt_builder.py: new PARALLEL_TOOL_CALL_GUIDANCE block (short, static,
cache-amortised) modeled on TASK_COMPLETION_GUIDANCE.
- system_prompt.py: inject right after the task-completion block, gated by
agent.valid_tool_names + the new toggle.
- agent_init.py: read agent.parallel_tool_call_guidance (default True).
- config.py: add the default under the agent section.
- test_prompt_builder.py: behavior-contract tests (batching steer, dependent
carve-out, length bound) — invariants, not wording snapshots.
Adapted from Cline's TypeScript tool-surface guidance to hermes-agent's
Python prompt-assembly architecture and config-over-env conventions.
* fix(desktop): never persist or restore a named custom provider as bare "custom"
Custom providers vanish from the Desktop/TUI model picker with
"No LLM provider configured" — repeatedly fixed (#44062, #44109, #45578)
and repeatedly regressed (#44022, #47714) because every fix only recovered
the entry identity from a persisted base_url. When a session is
persisted/restored with the resolved provider "custom" and NO base_url, bare
"custom" leaked through verbatim; resolve_runtime_provider("custom") routes to
the OpenRouter default URL with no api_key, so the next turn/resume dies.
Bare "custom" is the resolved billing class shared by every named providers:/
custom_providers: entry — it is not a routable identity. Centralize the
"never let bare custom escape" invariant in one helper,
runtime_provider.canonical_custom_identity(), and apply it at all four leak
sites in tui_gateway/server.py:
- _ensure_session_db_row — the ORIGIN: first DB write seeds the bad row
- _runtime_model_config — live persist
- _stored_session_runtime_overrides — resume restore (heals old rows; drops
unrecoverable bare custom so resume falls back to config default)
- _make_agent — rebuild / per-turn
The helper recovers custom:<name> from the endpoint URL when present, else
from config.model.provider (the durable identity left when no base_url
survived). Regression tests in test_custom_provider_session_persistence.py
lock the no-base_url vector at every site so it cannot regress again.
_runtime_model_config persisted the live agent's RESOLVED provider into
the session row's model_config JSON. For any named providers:/
custom_providers: entry, agent.provider is the literal string "custom",
so the entry name was lost (and the api_key is deliberately never
persisted). On session.resume or _reset_session_agent the stored
provider="custom" fed resolve_runtime_provider(requested="custom"),
which cannot match a named entry — the rebuild either raised "No LLM
provider configured" or silently resolved placeholder credentials
against the patched-back base_url.
Persist the REQUESTED/entry identity instead: a new reverse lookup
find_custom_provider_identity(base_url) maps the endpoint URL back to
the canonical custom:<name> menu key. _runtime_model_config stores that
key; _make_agent performs the same recovery for rows persisted before
the fix, falling back to passing the stored base_url as
explicit_base_url so the direct-alias branch still targets the
session's endpoint when no entry matches.

A cron job stored with `provider: "custom"` and a matching `providers.custom`
entry in config failed at execution with `auth_unavailable: providers=codex`.
Two layers conspired:
- `_get_named_custom_provider` returned None for bare "custom" *before*
scanning config, so a literal `providers.custom` entry was never matched and
resolution fell through to the global default (codex). Now it scans config
for an entry literally named "custom"; with none it still returns None,
preserving the legacy model.base_url trust path.
- `_resolve_model_override` blindly stripped bare "custom" at job creation and
pinned `model.provider` (e.g. codex). It now keeps "custom" when a configured
custom endpoint resolves, pinning the main provider only when it doesn't.
A non-numeric value in env vars like HERMES_STREAM_RETRIES,
HERMES_KANBAN_SPECIFY_MAX_TOKENS, GOOGLE_CHAT_MAX_BYTES, IRC_PORT, etc.
raised ValueError at import/init and crashed startup. Parse them safely,
falling back to the default.
Unified onto the existing utils.env_int(key, default) helper for core/
hermes_cli/tools modules instead of the original PR's three duplicate
local helpers; plugins keep minimal inline guards (no core-utils import).
All existing max()/min()/`or extra.get()` wrappers preserved.

Widens ViewWay's #20741 fix to the sibling config surface: a
custom_providers entry can pin its own output cap via max_output_tokens
(or max_tokens). _get_named_custom_provider now lifts it onto the
resolved runtime at all three return sites, and the gateway uses it as a
fallback only when the documented global model.max_tokens isn't set, so
the global key always wins.
Precedence: HERMES_MAX_TOKENS > model.max_tokens > provider
max_output_tokens > None. Closes the same #20741 truncation for users who
configure the cap per-provider rather than globally.
Picks up the intent of #19782 (alexcam1901), reimplemented to feed
ViewWay's max_tokens pipeline.
After the legacy session-key path was removed, two parameters became dead
surface on the Nous runtime-resolution chain:
- min_key_ttl_seconds: del'd inside refresh_nous_oauth_pure and pass-through /
telemetry-only in refresh_nous_oauth_from_state, _try_import_shared_nous_state,
_nous_device_code_login, and resolve_nous_runtime_credentials. It controlled the
now-deleted agent-key mint TTL and drives no behavior.
- inference_auth_mode: with the legacy mode gone, AUTO and FRESH are behaviorally
identical; the value only fed _normalize_nous_inference_auth_mode validation and
oauth trace output, never a branch.
Removing inference_auth_mode orphaned its whole supporting cluster
(NOUS_INFERENCE_AUTH_MODE_AUTO/FRESH, NOUS_INFERENCE_AUTH_MODES,
_normalize_nous_inference_auth_mode), and dropping min_key_ttl_seconds orphaned
DEFAULT_AGENT_KEY_MIN_TTL_SECONDS — all deleted here.
Updated every caller (run_agent, auxiliary_client, credential_pool, proxy adapter,
runtime_provider, web_server, main, auth_commands, setup) and pruned the matching
test kwargs. Deleted two tests that exercised the removed surface
(test_legacy_auth_mode_is_rejected, test_try_refresh_..._accepts_explicit_auth_mode).
No behavior change: net -134 LOC of dead code.
Allow custom OpenAI-compatible providers declared under `custom_providers:`
to set provider-specific `extra_body` fields and have Hermes merge them into
chat-completions requests when the matching custom endpoint is active.
This is a manual per-provider override rather than a model-name heuristic.
OpenAI-compatible Gemma thinking support is real, but the on-wire payload
shape is backend-specific: some servers want top-level `enable_thinking`,
while vLLM Gemma and NIM-style endpoints expect `chat_template_kwargs`.
A per-provider override is safer than picking one assumed payload.
Example config:
```yaml
custom_providers:
- name: gemma-local
base_url: http://localhost:8080/v1
model: google/gemma-4-31b-it
extra_body:
enable_thinking: true
reasoning_effort: high
```
For vLLM Gemma or NIM-style endpoints, use the nested shape those servers
expect:
```yaml
extra_body:
chat_template_kwargs:
enable_thinking: true
```
Changes:
- `hermes_cli/config.py`: preserve `extra_body` in normalized
`custom_providers:` entries and allow it in the validated field set.
- `hermes_cli/runtime_provider.py`: propagate custom-provider `extra_body`
as `request_overrides.extra_body` for named custom runtime resolution,
including credential-pool paths.
- `agent/agent_init.py`: at agent init, locate the matching custom-provider
entry by `base_url` (+ optional model) and merge its `extra_body` into
`AIAgent.request_overrides`, with caller-provided overrides winning on
conflicting top-level keys.
- `plugins/model-providers/custom/__init__.py`: keep existing CustomProfile
behavior (Ollama `num_ctx`, `think=False` when reasoning disabled);
user-configured `extra_body` flows through `request_overrides`.
- `website/docs/integrations/providers.md`: document the explicit
`extra_body` override and the vLLM/Gemma `chat_template_kwargs` variant.
- Tests cover config normalization, runtime propagation, model matching,
trailing-slash equivalence, fallback when no `model` field is set, and
caller-override merging precedence.
Verified end-to-end against `CustomProfile` via `ChatCompletionsTransport`:
configured `extra_body` reaches `kwargs.extra_body` on the wire request,
and coexists with profile-generated entries (Ollama `num_ctx`, `think=False`)
without clobber.
Salvaged from #29022 onto current `main`. Cosmetic typing edit in
`plugins/model-providers/custom/__init__.py` and a stale-base docs revert
in `providers.md` were dropped during cherry-pick.
Closes#29022
After #28660's host-gating fix, users with provider=custom and base_url
pointed at a commercial endpoint (DeepSeek, Groq, Mistral, …) hit
no-key-required even when they had the vendor-named env var set
(DEEPSEEK_API_KEY, GROQ_API_KEY, …). The issue author flagged this as
'what users intuitively expect'.
Adds _host_derived_api_key() to derive an env var name from the base URL
host using the *registrable* label (second-to-last). Appended to all three
api_key_candidates chains (_resolve_named_custom_runtime direct-alias path,
named-custom path, _resolve_openrouter_runtime non-openrouter branch).
Lookalike resistance: api.deepseek.com.attacker.test resolves to vendor
label 'attacker', NOT 'deepseek' — DEEPSEEK_API_KEY stays put. IPs and
loopback yield no vendor label. Already-handled vendors (OPENAI/OPENROUTER/
OLLAMA) are filtered to prevent bypass of the explicit host-gated paths.
Adds 6 tests covering positive paths (DeepSeek, Groq), the lookalike attack,
loopback rejection, the already-handled-vendor filter, and direct helper
unit tests.
Also adds erhnysr to AUTHOR_MAP.
- Preserve OPENROUTER_API_KEY for explicit mirror/proxy configs when
requested provider is openrouter and OPENROUTER_BASE_URL is set
- Gate OPENAI_API_KEY and OPENROUTER_API_KEY in named custom provider
path (_resolve_named_custom_runtime) on authoritative hosts
- Gate same keys in direct-alias path
- Update tests to reflect secure-by-default behavior for local endpoints
Custom endpoint provider was forwarding OPENAI_API_KEY and OLLAMA_API_KEY
to arbitrary hosts. Keys should only be sent to their authoritative domains
(openai.com, ollama.com) or when explicitly configured via pool/env.
- Gate OPENAI_API_KEY to openai.com hosts only
- Gate OLLAMA_API_KEY to ollama.com hosts only
- Return 'no-key-required' for unrecognized custom endpoints
- Update tests to reflect secure-by-default behavior
Closes#28660
When config.yaml has provider: ollama (or vllm/llamacpp/llama-cpp) with a
non-loopback base_url, auth.py's resolve_provider() correctly normalises
the alias to 'custom' at the top level, but two sites in runtime_provider.py
were still comparing the *original* string against the literal 'custom':
- _config_base_url_trustworthy_for_bare_custom() rejected non-loopback
URLs because cfg_provider_norm was 'ollama', not 'custom'.
- _resolve_openrouter_runtime() only entered the trust branch when
requested_norm == 'custom'.
Both sites now consult resolve_provider() and treat any alias that
resolves to 'custom' identically. Result: provider: ollama + LAN IP no
longer silently falls through to OpenRouter (HTTP 401), matching the
behaviour of provider: custom with the same base_url.
E2E verified across 6 cases (ollama/vllm/llamacpp/custom + LAN; ollama +
loopback; openrouter + cloud) — all route to the configured endpoint;
'frobnicate' + LAN still rejects with AuthError as before.
Also adds scripts/release.py AUTHOR_MAP entry for @stepanov1975
(PR #22074 — wizard config picker preservation, cherry-picked into the
preceding commit).
Six days after #23937 (608 fixes) the codebase had accumulated 241 new
PLR6201 violations. Same mechanical `x in (...)` → `x in {...}` fix,
same zero-risk profile: set lookup is O(1) vs O(n) for tuple and the
two are semantically equivalent for hashable scalar membership tests.
All 241 instances fixed via `ruff check --select PLR6201 --fix
--unsafe-fixes`, zero remaining. Every changed value is a hashable
scalar (str/int/None/enum/signal); no risk of unhashable runtime
errors. No behavior change.
Test plan:
- 119 files changed, +244/-244 (net zero) — exactly one-line edits
- `ruff check` clean afterward
- Compile checks pass on the largest touched files (cli.py, run_agent.py,
gateway/run.py, gateway/platforms/discord.py, model_tools.py)
- Subset broad test run on tests/gateway/ tests/hermes_cli/ tests/agent/
tests/tools/: 18187 passed, 59 pre-existing failures (verified against
origin/main with the same shape — identical failure count, identical
category — all xdist test-order flakes unrelated to this change)
Follows the same template as PR #23937 ([tracker: #23972](https://github.com/NousResearch/hermes-agent/issues/23972)).
Adds a new authentication provider that lets SuperGrok subscribers sign
in to Hermes with their xAI account via the standard OAuth 2.0 PKCE
loopback flow, instead of pasting a raw API key from console.x.ai.
Highlights
----------
* OAuth 2.0 PKCE loopback login against accounts.x.ai with discovery,
state/nonce, and a strict CORS-origin allowlist on the callback.
* Authorize URL carries `plan=generic` (required for non-allowlisted
loopback clients) and `referrer=hermes-agent` for best-effort
attribution in xAI's OAuth server logs.
* Token storage in `auth.json` with file-locked atomic writes; JWT
`exp`-based expiry detection with skew; refresh-token rotation
synced both ways between the singleton store and the credential
pool so multi-process / multi-profile setups don't tear each other's
refresh tokens.
* Reactive 401 retry: on a 401 from the xAI Responses API, the agent
refreshes the token, swaps it back into `self.api_key`, and retries
the call once. Guarded against silent account swaps when the active
key was sourced from a different (manual) pool entry.
* Auxiliary tasks (curator, vision, embeddings, etc.) route through a
dedicated xAI Responses-mode auxiliary client instead of falling back
to OpenRouter billing.
* Direct HTTP tools (`tools/xai_http.py`, transcription, TTS, image-gen
plugin) resolve credentials through a unified runtime → singleton →
env-var fallback chain so xai-oauth users get them for free.
* `hermes auth add xai-oauth` and `hermes auth remove xai-oauth N` are
wired through the standard auth-commands surface; remove cleans up
the singleton loopback_pkce entry so it doesn't silently reinstate.
* `hermes model` provider picker shows
"xAI Grok OAuth (SuperGrok Subscription)" and the model-flow falls
back to pool credentials when the singleton is missing.
Hardening
---------
* Discovery and refresh responses validate the returned
`token_endpoint` host against the same `*.x.ai` allowlist as the
authorization endpoint, blocking MITM persistence of a hostile
endpoint.
* Discovery / refresh / token-exchange `response.json()` calls are
wrapped to raise typed `AuthError` on malformed bodies (captive
portals, proxy error pages) instead of leaking JSONDecodeError
tracebacks.
* `prompt_cache_key` is routed through `extra_body` on the codex
transport (sending it as a top-level kwarg trips xAI's SDK with a
TypeError).
* Credential-pool sync-back preserves `active_provider` so refreshing
an OAuth entry doesn't silently flip the active provider out from
under the running agent.
Testing
-------
* New `tests/hermes_cli/test_auth_xai_oauth_provider.py` (~63 tests)
covers JWT expiry, OAuth URL params (plan + referrer), CORS origins,
redirect URI validation, singleton↔pool sync, concurrency races,
refresh error paths, runtime resolution, and malformed-JSON guards.
* Extended `test_credential_pool.py`, `test_codex_transport.py`, and
`test_run_agent_codex_responses.py` cover the pool sync-back,
`extra_body` routing, and 401 reactive refresh paths.
* 165 tests passing on this branch via `scripts/run_tests.sh`.
