feat(penpal): live-detect worktree additions and removals#548
Conversation
Watch each project's .git/worktrees/ directory so that `git worktree add` and `git worktree remove` are detected without restarting the server. On change, full re-discovery runs and an SSE event pushes the updated worktree list to the frontend. Co-Authored-By: Claude Opus 4.6 <[email protected]>
- Extract rediscoverProjects() helper to eliminate duplicated boilerplate across worktree, workspace, and source-detection event handlers - Protect worktreeWatchDirs and gitDirWatches reads in handleEvent with focusMu to prevent concurrent map read/write panic - Watch .git/ directory for projects without existing worktrees so the first `git worktree add` (which creates .git/worktrees/) is detected - Add GitCommonDir() helper extracted from GitWorktreesDir() - Add test for first-worktree creation detection via .git/ watch - Update no-worktrees test to verify .git/ is watched Co-Authored-By: Claude Opus 4.6 <[email protected]>

Summary
Previously, Penpal discovered git worktrees once at startup and never refreshed the list. If you ran
git worktree addorgit worktree removewhile Penpal was running, the sidebar's worktree list went stale — showing deleted worktrees and missing new ones.Now, Penpal watches each project's
.git/worktrees/directory for filesystem changes. When a worktree is added or removed, the worktree list updates automatically and the sidebar reflects the change within moments — no restart needed.discovery/worktree.go— NewGitWorktreesDir()resolves the.git/worktrees/metadata directory viagit rev-parse --git-common-dir, working for both main and linked worktreeswatcher/watcher.go— Base watches now include.git/worktrees/dirs; events there trigger full re-discovery and an SSE broadcast so the frontend picks up the change🤖 Generated with Claude Code
