Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00052 | $0.01083 |
| Opus 5 | $0.00026 | $0.00541 |
| Sonnet 5 | $0.00010 | $0.00217 |
| Haiku 4.5 | $0.00005 | $0.00108 |
Grade A, and why
worktree scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Git Worktree Manager
When to Use This Skill
Activate when the user:
- Invokes
/worktreedirectly - Mentions "worktree(s)" in any context
- Wants to "work on this in parallel" or "work on multiple things"
- Asks for an "isolated workspace" or "separate workspace"
- Says "clean up worktrees" or "what am I working on"
Do NOT activate when:
- User is doing normal branch switching (
git checkout,git switch) - No indication they need parallel workspaces
Conventions
Branch naming:
- Ticket path → strip dir +
.md, prefixfeature/:thoughts/shared/tickets/add-auth.md→feature/add-auth - Plain name → prefix
feature/unless already prefixed (fix/,chore/, etc.)
Worktree location: <repo-root>/../<repo-name>-worktrees/<branch-name> (sibling dir, outside main repo)
Default branch detection — never hardcode main:
DEFAULT_BRANCH=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|refs/remotes/origin/||') || DEFAULT_BRANCH="main"
Subcommand Dispatch
Parse the first argument. If none provided or intent is unclear, print:
/worktree create <name|ticket-path> — Create worktree + branch
/worktree list — All worktrees with dirty status
/worktree status — Detailed view (commits, ahead/behind)
/worktree remove <name> — Remove with safety checks
Examples:
/worktree create auth-refactor
/worktree create thoughts/shared/tickets/add-auth.md
When auto-triggered (no explicit subcommand), infer intent from context. If ambiguous, ask one clarifying question.
create
-
Resolve branch name using naming conventions above. If argument is a ticket path, read the ticket for context.
-
Check conflicts — run in parallel:
git branch --list "<branch-name>" git worktree listIf branch exists but has no worktree → offer
git worktree add <path> <existing-branch>(no-b). If worktree already exists at path → show its location, ask if user wants tocdthere instead.
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.

worktree is a skill published in the GitHub repository adrielp/ai-engineering-harness (20 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 52 tokens to every session and 1,083 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
