Enforce Fastify v5 plugin/route conventions for Node/TypeScript. Use when editing .ts/.js/.mjs that import fastify or @fastify/*, or when the user mentions Fastify, plugin, route, schema validation, encapsulation, fastify-plugin/fp, or lifecycle hooks. Declares route schemas in place of manual validation, wraps cross-scope decorators in fastify-plugin/fp, and scopes lifecycle hooks to the plugin that owns them.
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
> Targets Fastify v5 · verified 2026-09 (latest 5.12.4; v6 is still in alpha).
This skill enforces Fastify v5 plugin/route conventions for Node and TypeScript projects. The rule: every plugin is encapsulated by default; expose to parent scope only when needed; routes declare schemas, not manual validation.
Apply only when the file imports `fastify` or `@fastify/*`. If the project uses Express or Koa, **STOP** and ask the user before applying these rules.
## Plugin signature
```ts
import type { FastifyPluginAsync } from 'fastify'
import type { JsonSchemaToTsProvider } from '@fastify/type-provider-json-schema-to-ts'
export const userRoutes: FastifyPluginAsync = async (fastify, opts) => {
const app = fastify.withTypeProvider<JsonSchemaToTsProvider>()
app.get('/users/:id', { schema: getUserSchema }, async (req, reply) => {
return { id: req.params.id } // typed from getUserSchema (declared `as const`)
})
}
```
Use `async (fastify, opts) =>` over `(fastify, opts, done) =>`. Async return is the completion signal.

How to install
mdr add zhaojiannet/canon/fastify@sha256:9070f528d65de2edThe line at the top of this page pins the label git:20260914.a9571da, 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.
