Use this skill when you need documentation for a third-party library, SDK, or API before writing code that uses it — for example, "use the OpenAI API", "call the Stripe API", "use the Anthropic SDK", "query Pinecone", or any time the user asks you to write code against an external service and you need current API reference. Fetch the docs with chub before answering, rather than relying on training knowledge.
When you need documentation for a library or API, fetch it with the chub CLI
rather than guessing from training data. This gives you the current, correct API.
chub search "<library name>" --json
Pick the best-matching id from the results (e.g. openai/chat, anthropic/sdk,
stripe/api). If nothing matches, try a broader term.
chub get <id> --lang py # or --lang js, --lang ts
Omit --lang if the doc has only one language variant — it will be auto-selected.
Read the fetched content and use it to write accurate code or answer the question. Do not rely on memorized API shapes — use what the docs say.
After completing the task, if you discovered something not in the doc — a gotcha, workaround, version quirk, or project-specific detail — save it so future sessions start smarter:
chub annotate <id> "Webhook verification requires raw body — do not parse before verifying"
Annotations are local, persist across sessions, and appear automatically on future
chub get calls. Keep notes concise and actionable. Don't repeat what's already in
the doc.
Rate the doc so authors can improve it. Ask the user before sending.
chub feedback <id> up # doc worked well
chub feedback <id> down --label outdated # doc needs updating
Available labels: outdated, inaccurate, incomplete, wrong-examples,
wrong-version, poorly-structured, accurate, well-structured, helpful,
good-examples.
