Getting it into your agent

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.02608 |
| Opus 5.5 | $0.00016 | $0.01043 |
| Sonnet 5.5 | $0.00008 | $0.00522 |
| Haiku 4.5 | $0.00004 | $0.00261 |
Grade A, and why
git-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 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.
This is a copy
70% identical to git-worktree — 53 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Git Worktree Manager
This skill provides a unified interface for managing Git worktrees across your development workflow. Whether you're reviewing PRs in isolation or working on features in parallel, this skill handles all the complexity.
What This Skill Does
- Create worktrees from main branch with clear branch names
- List worktrees with current status
- Switch between worktrees for parallel work
- Clean up completed worktrees automatically
- Interactive confirmations at each step
- Automatic .gitignore management for worktree directory
- Automatic .env file copying from main repo to new worktrees
- Automatic dev tool trusting for mise and direnv configs with review-safe guardrails
CRITICAL: Always Use the Manager Script
NEVER call git worktree add directly. Always use the worktree-manager.sh script.
The script handles critical setup that raw git commands don't:
- Copies
.env,.env.local,.env.test, etc. from main repo - Trusts dev tool configs with branch-aware safety rules:
- mise: auto-trust only when unchanged from a trusted baseline branch
- direnv: auto-allow only for trusted base branches; review worktrees stay manual
- Ensures
.worktreesis in.gitignore - Creates consistent directory structure
# ✅ CORRECT - Always use the script
bash ${CLAUDE_PLUGIN_ROOT}/skills/git-worktree/scripts/worktree-manager.sh create feature-name
# ❌ WRONG - Never do this directly
git worktree add .worktrees/feature-name -b feature-name main
When to Use This Skill
Use this skill in these scenarios:
- Code Review (
/ce:review): If NOT already on the target branch (PR branch or requested branch), offer worktree for isolated review - Feature Work (
/ce:work): Always ask if user wants parallel worktree or live branch work - Parallel Development: When working on multiple features simultaneously
- Cleanup: After completing work in a worktree

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.

git-worktree is a skill published in the GitHub repository Jerrylalala/compound-engineering (6 stars, last pushed 4mo ago), licensed MIT. It adds 39 tokens to every session and 2,608 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 70% identical to git-worktree, differing in 53 lines, and is treated as a copy.
Other skills, from other repositories
merge-batch
Prepare and merge an owner-selected PR batch with contributor credit and exact-candidate admission. Use for a pasted PR list; combined focused validation is diagnostic, and every actual landing still requires its applicable checks and authorization.
prowler-commit
Creates professional git commits following conventional-commits format. Trigger: When creating commits, after completing code changes, when user asks to commit.
gh-auth-isolation
Safely manage multiple GitHub identities (EMU + personal) in agent workflows.
comet-github
A routing guide for Comet-related GitHub work. It directs requests about pull requests, issues, CI failures, ideas, and fixes to the appropriate review or implementation process.
github-skill
Work with GitHub via the gh CLI — clone repositories, create/list/merge pull requests, create/list issues, and run any other gh command (API calls, workflow runs, releases, repo administration). List operations return parsed JSON.
release-helper
Ensures configuration and code changes are released correctly. Use PROACTIVELY whenever you edit config.json, change any setting, or fix a configuration bug in this project, so the change reaches production.
