This skill activates when working with Cloudflare Workers bindings like D1, KV, R2, Durable Objects, or environment variables. It provides patterns for database access, caching, file storage, and secrets management.
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
# Cloudflare Bindings
Patterns for Cloudflare Workers bindings in Hono.
## Type Definitions
Define all bindings in a central type:
```typescript
// types/bindings.ts
export type Env = {
Bindings: {
// D1 Database
DB: D1Database
// KV Namespace
KV: KVNamespace
// R2 Bucket
BUCKET: R2Bucket
// Durable Object
COUNTER: DurableObjectNamespace
// Environment Variables
ENVIRONMENT: 'development' | 'staging' | 'production'
API_KEY: string
JWT_SECRET: string
}
Variables: {
user: User
requestId: string
}
}
```
## D1 Database
### Basic Queries
```typescript
app.get('/users', async (c) => {
const db = c.env.DB
// Select all
const { results } = await db
.prepare('SELECT * FROM users WHERE deleted_at IS NULL')
.all()
return c.json({ data: results })
})
app.get('/users/:id', async (c) => {
const db = c.env.DB
const id = c.req.param('id')
// Select one
const user = await db
.prepare('SELECT * FROM users WHERE id = ?')
.bind(id)
.first()
if (!user) {
return c.json({ error: 'User not found' }, 404)
}
return c.json({ data: user })
})
```

How to install
mdr add smicolon/ai-kit/cloudflare-bindings@sha256:17b8ff0feee419a4The line at the top of this page pins the label git:20260215.92455aa, 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.
