## Provider Contract
A provider registers synchronously from its `apply()` and returns `readonly SkillCandidate[]` from `list(options)` when discovery is requested. The provider, lookup options, candidates, and loaded definitions are readonly same-process contracts: the registry borrows them rather than cloning, freezing, or rebinding callbacks. Remote setup, authentication, and discovery belong in the awaited `list()` call rather than plugin registration. Providers should stop promptly when `options.signal` aborts; the registry also stops awaiting uncooperative discovery and loading work so agent cancellation cannot hang prefix composition or skill loading.
A provider registers synchronously and performs remote setup, authentication, and discovery in its awaited `list(options)` call. Provider objects, lookup options, candidates, and definitions are borrowed readonly rather than cloned or rebound. Providers should honor `options.signal`; the registry also stops awaiting uncooperative discovery or loading after cancellation.
The registry validates parsed provider candidates before caching them and validates loaded definitions before returning them. The winning provider receives the exact candidate and opaque `locator` identity it returned from `list()`; a local provider can therefore use a file-path handle while a remote provider can use a URL, id, or version token. Callers and providers must honor the readonly contract after handing values to the registry.
The registry validates candidates before caching and definitions before returning them. The winning provider receives the same candidate and opaque `locator` it returned from `list()`, allowing backend-specific file, URL, id, or version handles. Callers and providers must preserve the readonly contract.
Parsed candidate and loaded-definition fields are validated at the provider boundary: names/descriptions/content use their declared string types, ranks are finite numbers, and `disableModelInvocation` is boolean when present. Candidate contract violations fail fast because the provider or its parser is malformed; a provider `list()` rejection is treated as a transient source failure, logged, skipped for that request, and not cached. Only completed catalogs are cached, and a provider/runtime revision change during discovery discards the stale result and retries. Duplicate skill names are resolved first-wins by `rank`, provider registration order, then the provider's own local order. The final summary list is sorted by skill `name` for deterministic consumers.
Contract violations fail fast. A rejected `list()` is treated as a transient source failure: it is logged, skipped, and not cached. Only completed catalogs are cached; a provider or runtime revision change discards an in-flight result and retries. Duplicate names resolve by rank, provider registration order, then provider-local order. Summaries are sorted by skill name.
