Backend Factory - Git History Time-Lapse

Generate a time-lapse visualization showing how your backend architecture evolved commit by commit.

Step 1: Check Server

curl -s http://localhost:7777/api/status

If the server is not running, tell the user to run /backend-factory:start first.

Step 2: Get Git History

Determine the number of commits from $ARGUMENTS (default 15).

git log --oneline --format='%H|%h|%s|%an|%aI' -${N:-15}

Step 3: Analyze Each Commit

Process commits in reverse chronological order (oldest first). For each commit:

1. Create an isolated worktree:

   git worktree add /tmp/factory-timelapse-<hash> <hash> --detach 2>/dev/null
   

2. Run analysis:

   node ${CLAUDE_PLUGIN_ROOT}/analysis/analyze.js /tmp/factory-timelapse-<hash>
   

3. Clean up immediately:

   git worktree remove /tmp/factory-timelapse-<hash> --force 2>/dev/null
   

Step 4: Build Timelapse Array

Compare each snapshot to the previous one and compute diffs. For each commit, write a brief "factory renovation log" narrative.

Step 5: POST Timelapse Data

TMPFILE=$(mktemp /tmp/factory-timelapse-XXXXXX.json)
curl -s -X POST http://localhost:7777/api/timelapse \
  -H "Content-Type: application/json" \
  -d @"$TMPFILE"
rm -f "$TMPFILE"

Step 6: Report

• Time-lapse generated with N snapshots
• Use the timeline slider at http://localhost:7777 to scrub through history
• Press play to auto-advance
• Each snapshot shows the factory at that point in time

Error Handling

Always clean up worktrees:

git worktree list | grep factory-timelapse | awk '{print $1}' | xargs -I{} git worktree remove {} --force 2>/dev/null
