fetcher-decorator-service from ahoo-wang/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ahoo-wang/skills/fetcher-decorator-service@git:20261004.2702e5dPins git:20261004.2702e5d in mdr.lock. Pin the fingerprint instead.

Declare HTTP endpoints as a typed class with `@ahoo-wang/fetcher-decorator`: `@api`, `@get`/`@post`/`@put`/`@patch`/`@del`, `@path`/`@query`/`@header`/`@body`, return types, result extractors, `beforeExecute`/`afterExecute`. Use when writing or debugging a decorated service class. Direct `fetcher.get/post` calls, URLs built at runtime, client setup or interceptors (even for decorated services): fetcher-integration; React state: fetcher-react-hooks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# fetcher-decorator-service
## Decisions
- **Decorator service vs direct calls**: use a class when endpoints are stable and discoverable; call the fetcher directly (`$fetcher-integration`) when URLs or bodies are built dynamically.
- **Which fetcher**: `@api(basePath, { fetcher: 'api' })` resolves a `NamedFetcher` by name (or takes a `Fetcher` instance) on every call, falling back to `fetcherRegistrar.default`, which throws if nothing is named `'default'`. An instance `apiMetadata` field is shallow-merged over the class options on every call, so replacing or mutating it applies to the next call.
- **Cross-cutting behaviour** (auth, retry, 401 redirects) stays in fetcher interceptors (`$fetcher-integration`). `afterExecute` runs only after a successful (or interceptor-recovered) exchange — it is not a `finally`, and under the default status validation a 401 rejects with `HttpStatusValidationError` before it.

How to install
mdr add ahoo-wang/skills/fetcher-decorator-service@sha256:039ac635a0128e7cThe line at the top of this page pins the label git:20261004.2702e5d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
