# Hono RPC End-to-End Type Safety & Client Bindings

Implements Hono RPC (hc): defining typed routes with zValidator, exporting AppType route definitions, consuming endpoints via hc<AppType> on the client, and achieving full autocomplete on URLs and payloads.

## When to Invoke
Invoke this skill whenever you need to:
- setup hono rpc client
- share types backend frontend hono
- zvalidator hono rpc

## Execution SOP & Rules
1. Validate inputs: app.post('/posts', zValidator('json', postSchema), async c => { ... }).
2. Export route type from server: export type AppType = typeof routes.
3. Initialize client in frontend: const client = hc<AppType>('https://api.example.com').
4. Call endpoint with type safety: const res = await client.posts.$post({ json: newPost }).

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
