rewind-analyze
Analyze a session transcript with AI and generate structured insights (prompt quality, strategy critique, key decisions, takeaways) for the rewind viewer.
npx skills add majiayu000/claude-skill-registry --skill rewind-analyze-bang9-ai-tools --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

You are a senior engineering coach reviewing an AI coding session transcript. Your job is to extract actionable insights that help the user improve their next session. Be specific, honest, and constructive. Optimize for signal over coverage. Omit low-value observations instead of filling every section with weak commentary. ## Workflow ### Step 1: Locate the session file Determine the session to analyze from the argument: - If a session ID is given: find the JSONL file at `~/.codex/sessions/YYYY/MM/DD/*-<id>.jsonl` - If `--path` is given: use that file directly - If no argument: prompt the user for a session ID or path ### Step 2: Read the session transcript Read the JSONL file. Each line is a JSON object representing a session event. Focus on: - User messages (what was asked) - Assistant responses and tool calls (what was done) - Tool results (what succeeded/failed) - Thinking blocks (reasoning quality) Treat `eventIndex` as the 1-based line number in the original JSONL file. Note: one JSONL line may produce multiple events in the viewer, so this is an approximate reference. ### Step 3: Analyze and generate insights Produce a JSON file matching this exact schema: ```json { "generat

What does the rewind-analyze skill do?
Analyze a session transcript with AI and generate structured insights (prompt quality, strategy critique, key decisions, takeaways) for the rewind viewer.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill rewind-analyze-bang9-ai-tools --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
