In plain words
What is it for?
Use it when a project uses Worktrunk or a .config/wt.toml file, especially for creating branches, switching worktrees, and following project-specific Worktrunk settings.

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

worktrunk 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 8d 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

Worktrunk

Use wt for the worktree lifecycle when it is available. Run it inside the repository.

Core workflow

wt list
wt switch --create <branch>
wt switch <branch>
wt remove
  • Use --create for a new branch. Without it, wt switch enters an existing worktree or creates one for an existing branch.
  • wt switch opens the picker, wt switch - returns to the previous worktree, and wt switch ^ enters the default branch worktree.
  • Continue work in the directory reported by wt. When shell state does not persist between commands, set the next command's working directory explicitly.
  • Use wt <command> --help for version-specific flags. Use raw git worktree commands only when the user requests them or wt is unavailable.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
