Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Extract Skill **Typically runs automatically via SessionStart hook.** Process pending learning extractions from previous sessions. ## How It Works The SessionStart hook runs: ```bash ao extract ``` This checks for queued extractions and outputs prompts for Claude to process. ## Manual Execution Given `/extract`: ### Step 1: Check for Pending Extractions ```bash ao extract 2>/dev/null ``` Or check the pending queue: ```bash cat .agents/ao/pending.jsonl 2>/dev/null | head -5 ``` ### Step 2: Process Each Pending Item For each queued session: 1. Read the session summary 2. Extract actionable learnings 3. Write to `.agents/learnings/` ### Step 3: Write Learnings **Write to:** `.agents/learnings/YYYY-MM-DD-<session-id>.md` ```markdown # Learning: <Short Title> **ID**: L1 **Category**: <debugging|architecture|process|testing|security> **Confidence**: <high|medium|low> ## What We Learned <1-2 sentences describing the insight> ## Why It Matters <1 sentence on impact/value> ## Source Session: <session-id> ``` ### Step 4: Clear the Queue ```bash ao extract --clear 2>/dev/null ``` ### Step 5: Report Completion Tell the user: - Number of learnings extracted - Key insights - Location of learni

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.
