Ships the first half of the queued Hermes adapter expansion. PR 2 only
supported Nous Portal + OpenRouter; this adds 13 more providers reachable
via OpenAI-compat endpoints. Native SDK paths for Anthropic + Gemini are
Phase 2 (better tool-calling + vision fidelity).
## What's new
**`workspace-template/adapters/hermes/providers.py`** (new file, 220 LOC):
- ``ProviderConfig`` dataclass: name, env vars, base URL, default model, auth scheme, docs
- ``PROVIDERS`` dict with 15 entries across 4 groups:
- PR 2 baseline: nous_portal, openrouter
- Frontier commercial: openai, anthropic, xai, gemini
- Chinese providers: qwen, glm, kimi, minimax, deepseek
- OSS/alt: groq, together, fireworks, mistral
- ``RESOLUTION_ORDER`` tuple: priority for auto-detect (back-compat first,
then commercial, then Chinese, then OSS/alt)
- ``resolve_provider(explicit=None)`` -> (ProviderConfig, api_key)
- With explicit name: routes to that provider, raises if env var empty
- Without: walks RESOLUTION_ORDER, first env-var-set provider wins
**`workspace-template/adapters/hermes/executor.py`** (refactored):
- `create_executor(hermes_api_key=None, provider=None, model=None)` now has
three parameters:
- `hermes_api_key`: PR 2 back-compat — routes to Nous Portal
- `provider`: canonical short name from the registry (e.g. "anthropic")
- `model`: optional override of the provider's default model
- Delegates all resolution to `providers.resolve_provider()` — no more
hardcoded URLs or env var lookups in the executor itself
- `HermesA2AExecutor.__init__` no longer has Nous-specific defaults; callers
pass base_url + model explicitly (which create_executor always does)
**`workspace-template/tests/test_hermes_providers.py`** (new file, 26 tests):
- Registry shape invariants (count >= 15, no duplicates, every config valid)
- PR 2 back-compat: HERMES_API_KEY / OPENROUTER_API_KEY still route correctly
- Auto-detect for every provider in the registry (parametrized — guards against
typos in env var lists)
- Explicit `provider=` bypass of auto-detect
- Error cases: unknown provider, explicit-but-empty, auto-detect-with-no-env
- All 26 tests pass locally in 0.08s
## Back-compat guarantees
| Scenario | PR 2 behavior | This PR behavior |
|---|---|---|
| `create_executor(hermes_api_key="x")` | Nous Portal | Nous Portal (unchanged) |
| `HERMES_API_KEY=x` env, auto-detect | Nous Portal | Nous Portal (unchanged) |
| `OPENROUTER_API_KEY=x` env, auto-detect | OpenRouter | OpenRouter (unchanged) |
| Both env + explicit hermes_api_key param | Nous Portal (param wins) | Nous Portal (param wins, unchanged) |
Nothing existing can break. New callers gain access to 13 more providers.
## What's NOT in this PR (Phase 2)
- **Native Anthropic Messages API path** — better tool calling, vision, extended
thinking. Requires pulling in `anthropic` SDK. ~50 LOC.
- **Native Gemini generateContent path** — for vision + google tools. Requires
`google-genai` SDK. ~50 LOC.
- **Streaming support across all providers** — current executor is non-streaming
(single chat.completions.create call). Streaming works with openai.AsyncOpenAI
but hasn't been wired to the A2A event queue path. ~30 LOC.
- **Per-provider model overrides in config.yaml** — Phase 1 uses the registry's
default_model. Phase 2 adds a `hermes: { provider: qwen, model: qwen3-coder-plus }`
block in the workspace config.
- **`.env.example` updates** — not critical since the registry itself documents
every env var via the `env_vars` field, but nice-to-have.

## Test plan
- [x] Unit tests: 26/26 pass locally (pytest)
- [ ] CI will run on the self-hosted macOS arm64 runner
- [ ] Smoke test in a real workspace: set QWEN_API_KEY and verify Technical
Researcher actually hits Alibaba DashScope successfully
- [ ] Integration test per provider with real API keys (gated on env, skip
when not set — Phase 2 CI addition)
