fetcher-openapi-types SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
fetcher-openapi-types from ahoo-wang/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Type OpenAPI 3.0/3.1 documents in TypeScript with the type-only `@ahoo-wang/fetcher-openapi`: `OpenAPI`, `PathItem`, `Operation`, `Schema` (incl. JSON Schema 2020-12 keywords), `Parameter`, `Components`, `X | Reference` unions, `x-*` extensions. Use when reading, writing, walking or transforming a spec in code. Not a client generator (moved out of fetcher in 6.0) and not an HTTP client — for calls use fetcher-integration.
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-openapi-types
## Decisions
- **Type-only package**: import with `import type { … } from '@ahoo-wang/fetcher-openapi'` (single entry; the built JS is empty). There are no runtime guards or `$ref` resolvers — write your own narrowing.
- **Client generation is not here**: it left fetcher in 6.0 (see `$fetcher-v6-migration`). Use these types to inspect or build specs, not to produce clients.
## Gotchas a capable model gets wrong
- Reference-able slots are `X | Reference` — `Components` values, `Operation.parameters`, `requestBody`, `Responses` entries, `Schema.items`, `properties`, `allOf`/`anyOf`/`oneOf`/`not`, `$defs`, `prefixItems`, `if`/`then`/`else`, header/example/link maps, `webhooks`. Narrow before reading fields. Not reference-able: `Paths` values, `Callback` values, `content` media types.
- `PathItem` has its own optional `$ref`, so a bare `'$ref' in obj` check misclassifies path items; only use it on slots typed `X | Reference`. `Schema` declares no `$ref`, so `'$ref' in schema` is the Schema/Reference test.
- `additionalProperties`, `unevaluatedProperties` and `unevaluatedItems` are `boolean | Schema | Reference`: rule out the boolean before `'$ref' in`.

How to install
mdr add ahoo-wang/skills/fetcher-openapi-types@sha256:a0c7c29939d7b98eThe 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.
