Based on SOC occupation classification
Standard Schema socka contracts (defineSocka), v1 wire envelopes, SockaSession/SockaWebSocketClient, React useSockaSession and SockaSessionProvider, SockaError.
SockaDoSession and SockaWebSocketDO on Cloudflare Durable Objects—contract, handlers, wireFormat, SockaError; extends websocket-do BaseSession.
Standard Schema v1 for socka contracts and wire validation—Zod, Valibot, or any compatible library; no Zod-only public surface.
Enforce strict TypeScript typing without escape hatches. Never use `any`, `as` casts to bypass the compiler, or similar workarounds—find the proper typed solution instead.
React Router v7 routing patterns and environment variable configuration. Use when adding routes, configuring routing, or setting up environment variables.
Read when implementing multi-phase work after a plan exists. Mandatory—mkdir+touch then Write/StrReplace (no heredocs), update the temp punch list at every phase boundary, one item at a time, per-phase tests. Complements punch-list-planning for authors.

Use this skill whenever you touch Cloudflare Workers test apps or packages that rely on generated worker env typings.
Use this skill if any of the following are true:
durable_objects bindings in wrangler.jsonc or wrangler.app.jsoncsrc/worker.ts, workers/app.ts, DO classes)Env properties or worker bindingsNEVER manually create or edit worker-configuration.d.ts (or any generated worker env .d.ts) files.
These files must be regenerated by toolchain commands.
Update source-of-truth config/code first:
wrangler.jsoncwrangler.app.jsoncsrc/worker.ts, workers/app.ts, DO bindings usage)Run app typegen command from that app directory:
bun run typegenThis should run React Router typegen and Wrangler/cf-typegen in this repo's scripts.
If needed, run explicit worker type generation command used by the app scripts:
bun run cf-typegenValidate:
bun run typecheck.d.ts output.
