capture — stage code samples for signature extraction

When invoked

• On session start if .signature-cache/ is empty or >24h stale
• Manually via /cogsig capture
• Triggered by extract skill if no cache exists

What it does (Day 2 target)

1. Collect last N commits authored by the user (git log --author=$GIT_USER_EMAIL -n 50 --name-only)
2. Collect last M files modified in working tree
3. Read 3-5 representative samples per file (function-level if possible)
4. Write to .signature-cache/samples.json with {path, language, content, modified_ts} rows
5. Emit summary: N samples / M languages / K lines cached

What it does NOT do

• Does not call the API (extract's job)
• Does not persist samples beyond .signature-cache/ (gitignored — signature is user-local)
• Does not interpret or analyze — that's extract

Output

.signature-cache/samples.json — ready for extract.

Status

• SKILL.md stub (Day 1)
• implementation (Day 2)
