Get API Docs via context-hub (chub)

MANDATORY RULE: Before writing code that uses ANY external library or API, fetch the current documentation with chub. Never rely on memorized API shapes.

Pre-flight Check

Before first use in a session, verify chub is installed:

command -v chub >/dev/null 2>&1 || npm install -g @aisuite/chub

Step 1 — Find the right doc ID

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.

Step 2 — Fetch the docs

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.

Step 3 — Use the docs

Read the fetched content and use it to write accurate code. Do not rely on memorized API shapes — use what the docs say.

Step 4 — Annotate discoveries

After completing the task, if you discovered something not in the doc — a gotcha, workaround, version quirk, or project-specific detail — save it:

chub annotate <id> "Webhook verification requires raw body — do not parse before verifying"

Annotations persist across sessions and appear on future chub get calls.

Step 5 — Give feedback

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 down --label outdated     # doc needs updating

Labels: outdated, inaccurate, incomplete, wrong-examples, wrong-version, poorly-structured, accurate, well-structured, helpful, good-examples.

Quick Reference

Goal	Command
List everything	chub search
Find a doc	chub search "stripe"
Fetch Python docs	chub get stripe/api --lang py
Fetch JS docs	chub get openai/chat --lang js
Fetch multiple	chub get openai/chat stripe/api --lang py
Save a note	chub annotate stripe/api "needs raw body"
List notes	chub annotate --list
Rate a doc	chub feedback stripe/api up

When to Use (Auto-trigger)

Use chub whenever you encounter ANY of these in code:

• import / from X import / require() for external packages
• New library/framework being added to the project
• API endpoint design referencing external service docs
• Version upgrades or migrations
• Unfamiliar or rarely-used library features

Integration with Codeloop

During autonomous development loops (codeloop start), ALWAYS run chub get before implementing features that touch external APIs. This prevents hallucinated API calls that would break the build and waste loop iterations.
