The delegation imported ``plugins.model_providers.deepseek`` — the only cross-plugin
module import in the tree, and one that resolves solely through the loader's
sys.modules shim (popped again if the deepseek plugin fails to load). Look the
profile up with get_provider_profile("deepseek") instead: already imported from
``providers``, honours a user override of the profile, degrades to the base no-op
without a try/except.
Drop the ``len(m) <= len("deepseek/")`` guard — the native profile returns
({}, {}) for an empty id anyway. Bind the expected value in the parity test and
assert it is non-empty so the equality cannot pass as ({}, {}) == ({}, {}).
vertex, bedrock and copilot-acp each overrode ProviderProfile.fetch_models with an identical `return None`, and the overrides could not simply be deleted because the base implementation derives a URL from base_url and would GET e.g. bedrock-runtime.../models or acp://copilot/models. ProviderProfile now carries `supports_model_listing` (default True); the base fetch_models returns None before touching the network when it is False, and the three SDK/subprocess-backed profiles set it in their constructors instead of overriding. Separately, two catalog GETs still went through bare urllib.request.urlopen: commandcode's fetch_models and hermes_cli.models._fetch_ai_gateway_models (which sends the AI Gateway bearer). Both now use the redirect-safe open_credentialed_url path (_urlopen_model_catalog_request in models.py, also applied to the unauthenticated fetch_ai_gateway_models for consistency). This is a security behavior change: a cross-origin redirect from either endpoint no longer forwards the Authorization/attribution headers to the redirect target. The AI Gateway tests that patched the global urlopen are repointed at hermes_cli.models._urlopen_model_catalog_request (the seam tests/hermes_cli/test_models.py already uses), the commandcode test patches open_credentialed_url on the plugin module, and two invariant tests pin the no-network guard and the bearer routing.
The deepseek plugin is bundled and always loads, so the try/except around
the delegation import was defense-in-depth for a path that cannot fail.
Tests reduced to the two contracts that matter: /reasoning none reaches
the wire as thinking.disabled, and DeepSeek ids produce exactly the native
DeepSeek profile's output while non-DeepSeek families stay a no-op.
The bundled-plugin loader pops half-registered modules when a plugin
fails to load, so the lazy 'from plugins.model_providers.deepseek import
deepseek' could raise ImportError on every DeepSeek-routed CommandCode
turn — turning the soft 'thinking uncontrollable' bug into a hard
crash. Catch ImportError, log, and return the pre-fix no-op (review
feedback on #95241).
CommandCode fronts DeepSeek with vendor-prefixed ids
(deepseek/deepseek-v4-flash). DeepSeek V4+ defaults to thinking mode
when the thinking field is omitted, so /reasoning none changed the
Hermes session state but not the actual request -- the turn sat in
reflecting.../brainstorming... for minutes (#95232). Strip the vendor
prefix for DeepSeek-family ids and delegate to the native DeepSeek
profile's build_api_kwargs_extras (extra_body.thinking +
reasoning_effort mapping); other CommandCode model families keep the
base no-op behavior. The prior no-op tests codified the bug and are
rewritten to pin the new contract.
Follow-up to the salvaged CommandCode signature fix: accepting base_url
but ignoring it left custom endpoints (user-configured model.base_url /
COMMANDCODE_BASE_URL proxies) fetching the public catalog instead of the
configured one. Reviewer dansigma flagged this on PR #88851.
Class-wide fix, not a CommandCode patch:
- providers/base.py: a caller base_url that DIFFERS from the profile's
default now wins over models_url. Equality with the default means "not
customised" (callers pass base_url unconditionally, defaulting to the
profile's own URL) and keeps models_url as the endpoint, preserving the
OpenRouter-style split-catalog behavior.
- commandcode: _fetch_commandcode_models() takes the endpoint override;
both profile overrides forward base_url.
- Tests: base-class precedence (custom beats models_url, default does
not), CommandCode redirect via live local HTTP server incl. claude-*
filter, and default-echo hitting the canonical endpoint. All verified
to fail against the pre-fix implementation (sabotage run).
The model picker's generic live-fetch path (hermes_cli/models.py
provider_model_ids) calls profile.fetch_models(api_key=..., base_url=...).
Both CommandCode overrides only accepted api_key/timeout, so every picker
open raised TypeError, which was silently swallowed, leaving the provider
with zero models.
Match the base ProviderProfile.fetch_models signature (base_url kwarg) and
add a regression test asserting both profiles accept it.
The provider-parity contract requires every CANONICAL provider to render a
card on the desktop Keys tab. /api/env rows are keyed by env var, and both
CommandCode profiles shared the single COMMANDCODE_API_KEY — so the
commandcode-anthropic profile had no row of its own and
test_provider_parity failed on CI (slice 6/12).
Fix: both profiles keep the shared API key, but each declares its own
base-URL override var (COMMANDCODE_BASE_URL / COMMANDCODE_ANTHROPIC_BASE_URL),
matching the sibling-provider pattern, so each renders its own card.
Verified: test_provider_parity.py + commandcode + providers suites green
locally (86 passed); PROVIDER_REGISTRY splits key vs base-URL vars correctly
for both profiles.
