Git Activity Fetcher

Fetch git commit history from local repositories into per-day cached JSON atoms at ~/.cache/recap/git/{repo}/{YYYY-MM-DD}/log.json. These atoms feed the /recap orchestrator for progressive timescale synthesis.

Invocation

/recap:git-activity --repos coworker:~/Work/basecamp/coworker --since 2026-03-23
/recap:git-activity --repos coworker:~/Work/basecamp/coworker,house-skills:~/Work/basecamp/house-skills --since 2026-03-23 --until 2026-03-30
/recap:git-activity --repos coworker:~/Work/basecamp/coworker --since 2026-03-23 --reuse

Contract

• Idempotent: same input produces same output, safe to re-run
• Day-cached: one JSON file per repo per day at ~/.cache/recap/git/{repo}/{YYYY-MM-DD}/log.json
• --reuse: skip fetch if cache exists and is marked complete
