Excerpt

rag-index-decisions — close the feedback loop

When to use this skill

Trigger this skill when, during a session, the team (or the agent + user together) produces:

A design decision with tradeoffs discussed (worth an ADR)
A novel bug fix whose root cause is non-obvious
A convention agreed on ("from now on we do X for Y")
A postmortem summary — even a paragraph
A URL / doc / paper that shaped the decision (worth ingesting via add_from_url)

Do NOT trigger for:

Trivial fixes (typo, formatting, obvious one-liner)
Session-only context that will not matter next time
Highly sensitive material that should NOT be in the RAG (secrets, PII, WIP negotiations)
Duplicates of things already indexed
