Basecamp Activity

Basecamp Activity Fetcher

Fetch Basecamp activity events into per-day cached JSON atoms. Supports two scopes:

• Project-scoped (--project): all events in a Basecamp project
• Person-scoped (--person): all activity by a specific user

Caches at ~/.cache/recap/basecamp-project/{id}/{YYYY-MM-DD}/activity.json or ~/.cache/recap/basecamp-person/{slug}/{YYYY-MM-DD}/activity.json.

Invocation

/recap:basecamp-activity --project 43483623 --since 2026-03-23
/recap:basecamp-activity --project 43483623 --since 2026-03-23 --until 2026-03-30 --reuse
/recap:basecamp-activity --person "Jeremy Daer" --since 2026-03-23

Contract

• Idempotent: same input produces same output, safe to re-run
• Day-cached: one JSON file per scope per day
• --reuse: skip fetch if cache exists and is marked complete
• Rate-limit aware: exponential backoff on 429 responses

Quick Run

# 1. Validate auth
basecamp auth status | jq -e '.data.authenticated' || { echo "Run: basecamp auth login"; exit 1; }

# 2. Determine date range
SINCE=$(date -d "7 days ago" +%Y-%m-%d)
UNTIL=$(date +%Y-%m-%d)

# 3. Run the fetcher (project-scoped)
"$SKILL_DIR/scripts/basecamp-activity.sh" \
  --project 43483623 --since "$SINCE" --until "$UNTIL"

# 4. Verify cache
ls ~/.cache/recap/basecamp-project/43483623/
cat ~/.cache/recap/basecamp-project/43483623/$SINCE/activity.json | jq '.metadata'

Where $SKILL_DIR = directory containing this SKILL.md.
