How do I install the Worktree Execution skill?

Run npx skillmds@latest add tomevault-io/worktree-execution in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Worktree Execution safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Worktree Execution?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Worktree Execution free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Worktree Execution

Git worktree management for isolated parallel prompt execution. Use when creating isolated environments for prompt comparison or managing worktree lifecycle. Provides creation, cleanup, and orphan detection scripts. Use when this capability is needed.

Worktree Management

Creation

Script: scripts/worktree-create.sh

# Default labels (original/optimized) for prompt eval
./scripts/worktree-create.sh [repo_root]

# Custom labels for skill eval
./scripts/worktree-create.sh [repo_root] baseline with-skill
./scripts/worktree-create.sh [repo_root] old-version new-version

Output (stdout):

/tmp/worktree-rashomon-{label_a}-20260114-123456
/tmp/worktree-rashomon-{label_b}-20260114-123456

Properties:

Location: ${TMPDIR:-/tmp}/
Naming: worktree-rashomon-{label}-{timestamp}
Branch: Detached HEAD at current commit
Labels default to original / optimized if not specified

Cleanup

Script: scripts/worktree-cleanup.sh

# Remove all rashomon worktrees
./scripts/worktree-cleanup.sh [repo_root]

# Remove specific worktrees
./scripts/worktree-cleanup.sh [repo_root] path1 path2

# Remove only orphaned worktrees (age > 1 hour)
./scripts/worktree-cleanup.sh --orphans [repo_root]

Cleanup Triggers:

After successful report generation
In finally block on any failure
On timeout
On startup (orphan detection)

Parallel Execution Principle

Key: To achieve true parallel execution, spawn both Task calls in a single message.

The calling command determines which agents to invoke and how to structure the Task calls. This skill provides only the worktree infrastructure.

Error Handling (Worktree Operations)

Scenario	Behavior
Creation fails	Report git error, suggest checking repository state
Cleanup fails	Log warning, attempt orphan cleanup on next run
Orphan detected	Force remove worktrees older than 1 hour

Scripts Reference

worktree-create.sh

Exit Code	Meaning
0	Success
1	Not a git repository
2	Creation failed

worktree-cleanup.sh

Exit Code	Meaning
0	Success (or nothing to clean)
1	Not a git repository
2	Cleanup partially failed

Constraints

No concurrent comparisons: One rashomon execution per repository
Git required: git 2.5+ for worktree support
Disk space: Sufficient space for worktree copies
