Supports rich suggestions with entity info. Typo-resilient.x402browser-useSet up Browser Use Cloud payments with x402 — pay per request from a crypto wallet (USDC on Base mainnet), no signup or API key. Two setups it works out up front — "just use it" (set up a wallet so you or Claude Code can run cloud browser tasks paid from the wallet — Claude writes and runs throwaway scripts, nothing touches your codebase) or "build it in" (install the SDK and write the key + code into your project). Walks through wallet setup, funding, .env, and a ~$1 test run. Use when the userprotobufbufbuildUse when working with Protocol Buffer (.proto) files, buf.yaml, buf.gen.yaml, or buf.lock. Covers proto design, buf CLI, gRPC/Connect services, protovalidate constraints, schema evolution, and troubleshooting lint/breaking errors.read-the-damn-docsbuilderioUse when implementing, integrating, upgrading, debugging, or answering anything involving third-party APIs, libraries, frameworks, CLIs, cloud services, model/provider SDKs, fast-moving product behavior, user requests for latest/current/official behavior, unfamiliar repo docs/specs, errors that may indicate API drift, or high-stakes auth, security, billing, data, migration, deployment, compliance, or privacy behavior. Forces Codex to web-search for current official docs and read primary docs befconnector-quickbookscaffeinelabsUse the `quickbooks-client` mops package whenever the user asks the canister to create/read/update invoices, customers, payments, items, or chart-of-account entries in QuickBooks Online (QBO), email an invoice, or run a QuickBooks query. The package wraps the QuickBooks Online Accounting API v3 at `https://quickbooks.api.intuit.com` via outbound HTTPS calls.connector-tmdbcaffeinelabsMANDATORY recipe for every Caffeine build that reads movie, TV or people data from a canister. The supported path is the `tmdb-client` mops package (The Movie Database Web API v3) over outbound HTTPS, authenticated with a v3 API key or a v4 read-access token. Hand-rolling `ic.http_request` calls to `api.themoviedb.org` is a FORBIDDEN anti-pattern — it bypasses the non-replicated-outcall safeguard, the generated JSON decoding of ~720 response models, and the credential handling.
