list-worktrees

list-worktrees is a skill for Claude Code from johardi/claude-stack. It costs 119 tokens per session (736 once invoked), scanned A, original, MIT.

A read-only tool for listing Claude agent worktrees, which are separate working directories used by coding agents. It shows each worktree’s branch, lock state, whether files changed, and whether commits have been pushed.

In plain words
What is it for?
Use it when checking which agent worktrees are open, which branches are stuck, or what agent-owned directories are clean, dirty, locked, or ahead of the remote.
Why use it?
It helps identify active agents, stale locks, unfinished changes, and branches that may need attention. This gives an overview before handing off or reclaiming a worktree.

Written for Claude Code: allowed-tools in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

list-worktrees scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

List Worktrees

A read-only inventory of Claude agent worktrees — the worktrees created by Agent({isolation: "worktree"}) or by cstack-collab orchestration. Used to figure out which worktrees exist before deciding what to do with them (handoff from inside, reclaim from outside).

When to Use

Use when:

  • The user types /cstack-collab:list-worktrees.
  • The user asks for an overview: "what agents are running", "which branches are stuck", "show me the worktrees", "what's holding feature/X".
  • Before invoking handoff or reclaim and the user hasn't named a specific worktree — list first, then ask.

Skip when:

  • The user already named a specific branch / agent id and just wants to act on it. Go straight to worktree.py inspect or to handoff / reclaim.

How to Run

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/worktree.py" list

Or, for downstream scripting:

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/worktree.py" list --json

Output shape (human-readable):

agent-<id>
  path:   <absolute path>
  branch: <branch name or "(detached)">
  lock:   unlocked | locked (pid N alive) | locked (pid N dead — stale lock)
  state:  clean | dirty | N unpushed | combinations

The script ignores plain user-created worktrees — only worktrees that carry the claude agent <id> lock marker or the CLAUDE_BASE file are listed.

Interpreting the Output

Lock State Recommendation
live PID clean Agent is working normally. Leave it alone.
live PID dirty / unpushed If the user wants to take the branch over: type /cstack-collab:handoff in that agent's session. Don't reclaim — it would kill the agent.
stale PID clean Safe to /cstack-collab:reclaim without flags.
stale PID dirty / unpushed /cstack-collab:reclaim (default --stash) preserves the work to a recovery ref.
unlocked any The harness has already released this. Reclaim removes the directory; nothing else to clean up.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
