gtr is a command-line tool that manages Git worktrees, which let developers keep multiple branches checked out in separate directories at the same time. It automates worktree creation, branch setup, configuration copying, dependency installation, and workspace preparation for reviews, coding agents, and parallel development. The catalogue contains instructions for using gtr.

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 | $0.02016 | $0.02016 |
| Opus 5.5 | $0.00806 | $0.00806 |
| Sonnet 5.5 | $0.00403 | $0.00403 |
| Haiku 4.5 | $0.00202 | $0.00202 |
Grade A, and why
git-worktree-runner copilot-instructions.md 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.

Copilot Instructions
Condensed guide for AI agents working in this repository. AGENTS.md and CLAUDE.md are the long-form versions; keep all three consistent.
What This Is
git gtr (Git Worktree Runner) is a Bash CLI that wraps git worktree with editor and AI-tool launching, file copying, hooks, and pull-request checkout. It is installed as a git subcommand. User-facing docs always say git gtr, never ./bin/gtr.
Layout
bin/git-gtr- entry point. Setsset -e, definesGTR_VERSION, sources every library, and dispatches inmain()with acaseon the first argument.bin/gtr- development wrapper thatexecsbin/git-gtr.lib/*.sh- sourced in this order:ui.sh(logging, prompts),args.sh(flag parser that fills_arg_*vars),config.sh(cfg_get,cfg_default,cfg_get_all),platform.sh(OS detection),core.sh(worktree CRUD,resolve_target,resolve_base_dir,sanitize_branch_name),copy.sh,hooks.sh(run_hooks_in/run_hooks, plusrun_hooks_exportfor postCd),provider.sh(GitHub/GitLab detection forclean),adapters.sh(adapter registries and loaders),launch.sh(editor/AI launch orchestration).lib/commands/*.sh- one file per subcommand definingcmd_<name>()(18 files, includingpr.shandtrust.sh).

Commands
new, pr, rm, mv|rename, go, run, editor, ai, copy, ls|list, clean, doctor, adapter|adapters, config, completion, init, trust, version, help. There is no open command; the editor command is editor. cd has no cmd_* handler: the dispatcher errors and points at git gtr help init, because gtr cd is a shell function emitted by init.
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.
