Adding Or Updating An Entry
Create or edit a top-level directory such as langchain/ or tdd/.
Keep the entry in one README.md.
Include category metadata near the top using the existing blockquote style.
Add practical sections: When To Use, Practical Tips, and Watch Outs.
Add or update the matching row in INDEX.md.
Superpowers Contributor Workflow
Superpowers is documented as a recommended way to work on this repository, not as a product feature of the catalog.
Recommended workflows:
Use brainstorming before adding a new tool, skill, or tip category.
Use writing-plans for multi-entry restructures or taxonomy changes.
Use verification-before-completion before claiming a catalog update is done.
Use systematic-debugging only when a script, validation command, or generated artifact fails.
INDEX.md — categorised tool index with pricing, audience, and recommendation notes.
docs/CONTRIBUTING.md — contribution checklist for library entries.
AGENTS.md — operational guidance for Codex sessions in this repo.
CLAUDE.md — operational guidance for Claude Code sessions in this repo.
