Fearvox 3d1d0a49fe fix(minimax): align default_aux_model with M3 frontier on minimax + minimax-cn
The minimax / minimax-cn / minimax-oauth profiles still advertised
M2.7 (and M2.7-highspeed for OAuth) as their default_aux_model,
predating the M3 release (2026-06-01). The user-facing
_PROVIDER_MODELS['minimax'] catalog top entry is M3, and the
recommended config for a Token-Plan install now sets
model.default: MiniMax-M3, so the aux default was the only
remaining drift.

Updates:

  * minimax        default_aux_model: M2.7        -> M3
  * minimax-cn     default_aux_model: M2.7        -> M3
  * minimax-oauth  default_aux_model: M2.7-highspeed -> M2.7
                    (M3 is not on the OAuth / Coding Plan tier per
                    platform docs as of this PR; the highspeed
                    variant was the 2x-cost regression from #4082
                    that PR #6082 collapsed to plain M2.7 for
                    minimax / minimax-cn but missed OAuth)

  * agent/auxiliary_client.py: drop the three legacy
    _API_KEY_PROVIDER_AUX_MODELS_FALLBACK entries for the minimax
    family. _get_aux_model_for_provider() reads from
    ProviderProfile.default_aux_model first (line 250) and only
    falls back to the dict when the profile has no aux model or
    the profile import fails. With the profile now set, the dict
    entries are dead code and a drift hazard. Mirrors the deepseek
    cleanup in 773a0faca.

  * tests/agent/test_minimax_provider.py: update the existing
    TestMinimaxAuxModel assertions from MiniMax-M2.7 to MiniMax-M3
    (the intent — 'standard, not highspeed' — is unchanged; the
    pin value is).

  * tests/plugins/model_providers/test_minimax_profile.py: new
    file mirroring tests/plugins/model_providers/test_deepseek_profile.py.
    Pins each of the three profiles' default_aux_model and
    asserts _get_aux_model_for_provider() returns it. A second
    class guards against the highspeed regression coming back.

Refs:
  - Closes #36196 in spirit (M3 support — the catalog half of
    that issue is #36212; this PR covers the profile half)
  - Related: #4082 (M2.7-highspeed 2x-cost), #6082 (previous
    M2.7-highspeed -> M2.7 fix that missed OAuth + the
    auxiliary_client.py fallback dict)
  - Pattern: 773a0faca (same profile-layer fix for deepseek)

Model Provider Plugins

Each subdirectory is a self-contained provider profile plugin. The directory layout mirrors plugins/platforms/:

plugins/model-providers/
├── openrouter/
│   ├── __init__.py      # registers the ProviderProfile
│   └── plugin.yaml      # manifest: name, kind, version, description
├── anthropic/
│   ├── __init__.py
│   └── plugin.yaml
└── ...

How discovery works

providers/__init__.py._discover_providers() scans this directory (and $HERMES_HOME/plugins/model-providers/) the first time anything calls get_provider_profile() or list_providers(). Each __init__.py is imported and expected to call providers.register_provider(profile).

User plugins at $HERMES_HOME/plugins/model-providers/<name>/ override bundled plugins of the same name — last-writer-wins in register_provider(). Drop a file there to replace a built-in.

Adding a new provider

  1. Create plugins/model-providers/<your_provider>/__init__.py:

    from providers import register_provider
    from providers.base import ProviderProfile
    
    my_provider = ProviderProfile(
        name="your-provider",
        aliases=("alias1", "alias2"),
        display_name="Your Provider",
        description="One-line description shown in the setup picker",
        signup_url="https://your-provider.example.com/keys",
        env_vars=("YOUR_PROVIDER_API_KEY", "YOUR_PROVIDER_BASE_URL"),
        base_url="https://api.your-provider.example.com/v1",
        default_aux_model="your-cheap-model",
    )
    
    register_provider(my_provider)
    
  2. Create plugins/model-providers/<your_provider>/plugin.yaml:

    name: your-provider-profile
    kind: model-provider
    version: 1.0.0
    description: Short sentence about the provider
    author: Your Name
    

Nothing else needs to change. auth.py, config.py, models.py, doctor.py, model_metadata.py, runtime_provider.py, and the chat_completions transport all auto-wire from the registry.

Non-trivial profiles

Override the ProviderProfile hooks in a subclass for per-provider quirks — see plugins/model-providers/openrouter/__init__.py for build_extra_body and build_api_kwargs_extras examples, and plugins/model-providers/gemini/__init__.py for thinking_config translation.
