remove-worktree

remove-worktree is a skill for Claude Code from careerchain-ys/stdd. It costs 133 tokens per session (762 once invoked), scanned A, original, Apache-2.0.

A skill for finding and deleting the current numbered Git worktree and its related development container. A worktree is a separate working directory connected to the same Git repository.

In plain words
What is it for?
Use it to identify a worktree, review its status, run the project's removal script, and optionally remove its Docker image.
Why use it?
It checks for active containers, uncommitted changes, and commits not yet pushed before removal, reducing the risk of discarding unfinished work.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is dir="../worktree-${i}".

Good fit Use it to identify a worktree, review its status, run the project's removal script, and optionally remove its Docker image.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

remove-worktree 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 2mo 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.

What it actually says

Worktree破棄スキル

現在のセッションで使用しているworktree環境を自動特定して破棄する。

1. 現在のworktree番号を自動判定

以下のコマンドで現在のworking directoryを確認する:

pwd
  • worktree-N の形式が含まれていれば、N がINSTANCE_ID
  • そうでない場合(プロジェクトの main worktree 等)は、Environment情報の "Additional working directories" を確認し、worktree-N にマッチするものからINSTANCE_IDを特定する
  • 複数ある場合はユーザーに確認する

2. 稼働中のworktreeと関連コンテナを確認

for i in 1 2 3 4; do
  dir="../worktree-${i}"
  if [ -d "$dir" ]; then
    branch=$(git -C "$dir" branch --show-current 2>/dev/null || echo "不明")
    container=$(docker ps -a --filter "label=devcontainer.local_folder=$(cd "$dir" && pwd)" --format "{{.Names}} ({{.Status}})" 2>/dev/null || echo "なし")
    echo "  worktree-${i}: ブランチ=${branch}, コンテナ=${container:-なし}"
  fi
done

3. 未コミット・未プッシュの変更を確認

特定したINSTANCE_IDを使って確認する:

git -C "../worktree-<INSTANCE_ID>" status
git -C "../worktree-<INSTANCE_ID>" log <primary_branch>..HEAD --oneline 2>/dev/null  # <primary_branch> = .stdd.config.yml の project.primary_branch

4. 破棄を実行

./scripts/remove-worktree.sh -i <INSTANCE_ID>

デフォルトではDockerイメージを保持して次回の起動を高速化する。 --clean を付けるとイメージも含めて完全削除する。

5. 破棄後の確認

docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}" | grep -E "REPOSITORY|vsc-<project_name>"
docker volume ls --format "table {{.Name}}" | grep -E "NAME|<project_name>|dind"

注意事項

  • 未コミットの変更がないか事前に確認すること
  • コミット済みだがpush未完了のブランチがないか確認すること
  • デフォルトではDockerイメージは保持される(次回起動の高速化のため)

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.
