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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00006 | $0.00295 |
| Opus 5.5 | $0.00002 | $0.00118 |
| Sonnet 5.5 | $0.00001 | $0.00059 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
git 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.
What it actually says
Git
Perform git operations in the workspace.
Common operations
- Status:
git status - Log:
git log --oneline -20 - Diff:
git diff - Staged diff:
git diff --cached - Add files:
git add <file>orgit add -A - Commit:
git commit -m "message" - Branch:
git branch -a - Switch branch:
git checkout <branch>orgit switch <branch> - Create branch:
git checkout -b <branch> - Pull:
git pull - Push:
git push - Stash:
git stash/git stash pop - Blame:
git blame <file> - Search history:
git log --grep="pattern" - Find who changed a line:
git log -p -S "text" -- <file>
Tips
- Always check
git statusbefore committing - Use
git diff --statfor a summary of changes - Use
git log --oneline --graphfor branch visualization
What ships with it
3 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.
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.
- 1mo ago First seen · 45 lines · 6 tokens per session scan A 415b43c5c7ed
git is a skill published in the GitHub repository gebruder/wirken (193 stars, last pushed 2d ago), licensed MIT. It adds 6 tokens to every session and 295 once invoked, about $0.0000 per session on Opus 5.5. 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.
