Use when working with the repo's bun run wt helper, Pierre-managed worktrees, dev-server port offsets, stale server cleanup, Playwright fixtures, or Chrome debug instances. Do not use this as a substitute for host-provided workspace isolation.
Use when preparing, splitting, reviewing, or creating git commits in this repo, especially after larger implementations that should be broken into independently verified commits.
Use when opening, inspecting, clicking, filling, snapshotting, or otherwise automating web pages for this repo, including local dev servers and browser-based verification.
Use when changing loops, collection processing, invalidation logic, tree/diff traversal, path scanning, virtualized rendering calculations, or any code where repeated scans or boolean control flow affect performance or correctness.
Use when adding or running tests, checking snapshots, choosing between Bun tests and Playwright, running lint/format/typecheck, or deciding the verification scope for a change.
Use when running repo scripts, adding or changing dependencies, editing package.json files, installing packages, or deciding how Bun workspace commands should be invoked in this monorepo.
Use when adding or changing packages/apps, TypeScript configs, workspace dependencies, package references, exports, or monorepo project-reference relationships.

Pierre includes a repo-specific git worktree helper for local/manual
parallelization outside host-managed agent workspaces. Managed Pierre worktrees
live at:
~/pierre/pierre-worktrees/<slug>/
Each managed Pierre worktree owns a port offset so dev servers, E2E fixtures, and the Chrome remote-debug instance do not collide. The main clone keeps historical default ports; linked Pierre worktrees shift ports.
If you are already inside a Conductor, Codex, Claude, or other host-provided workspace, do not create another worktree unless the user explicitly asks for a Pierre-managed worktree. Still use this skill when you start repo dev servers or E2E fixtures, because the cleanup and port-offset rules apply to those scripts.
The bun run wt suite is defined in scripts/wt.ts and manages only
Pierre-managed worktrees:
bun run wt new <slug> # create a worktree, allocate offset, bun install
bun run wt rm <slug> # kill its processes, remove the worktree
bun run wt clean # kill zombie servers on all managed worktree ports
bun run wt clean <slug> # clean one managed worktree
bun run wt ps # show per-worktree port status (LISTEN / -)
bun run wt list # summary of managed + external worktrees
Dev scripts pick up the offset through scripts/ws.ts, which reads
<worktree>/.env.worktree. Before starting, they run scripts/run-dev.sh to
kill any stale process bound to the target port.
If you start dev servers, Playwright fixtures, or Chrome debug instances inside a worktree, run cleanup before completing your turn:
bun run wt clean <slug>
Use bun run wt clean when you do not know the slug or need to clean every
managed worktree. Use bun run wt rm <slug> only when intentionally tearing
down the worktree itself.
