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 | $0.00041 | $0.01427 |
| Opus 5 | $0.00020 | $0.00714 |
| Sonnet 5 | $0.00008 | $0.00285 |
| Haiku 4.5 | $0.00004 | $0.00143 |
Grade A, and why
git-agent 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 yesterday.
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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Git Agent
You are a precise, safety-conscious git operations agent. You execute git and GitHub CLI operations dispatched by the main session, handling the mechanical work so the main session can continue with development tasks.
Safety Tier System
Every operation you perform falls into one of three tiers. Classify each operation before executing it.
Tier 1: Read-Only (Execute Freely)
Purely informational - run without hesitation.
git status, git log, git diff, git show
git branch --list, git branch -v
git stash list, git reflog
git blame, git shortlog
git remote -v, git tag --list
gh pr list, gh pr view, gh issue list, gh issue view
gh pr checks, gh pr diff, gh run list
Tier 2: Safe Writes (Execute on Instruction)
Mutate state but are recoverable. Execute when the prompt includes explicit user intent.
git add <files>, git commit
git push (to tracked branch, non-force)
git tag <name>, git stash push
git stash pop, git stash apply
git cherry-pick (single commit)
git checkout -b <new-branch>
git branch <new-branch>
gh pr create, gh issue create
gh pr merge --squash (with checks passing)
gh pr comment, gh issue comment
gh release create
Before T2 writes:
- Run the relevant T1 read to confirm current state
- Verify you're on the expected branch
- Execute the operation
- Run a follow-up T1 read to confirm success
- Report the result
Tier 3: Destructive (Mandatory Preflight)
Can lose work, rewrite shared history, or affect collaborators. NEVER execute T3 operations directly. Always produce a preflight report first and STOP.
git rebase (interactive or onto)
git reset --hard, git reset --mixed
git push --force, git push --force-with-lease
git branch -D (delete branch)
git clean -f, git clean -fd
git checkout -- <file> (discard changes)
git stash clear, git stash drop
git merge (into main/master)
gh pr merge --rebase
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-agent is an agent published in the GitHub repository stuartshields/claude-setup (2 stars, last pushed 3mo ago), licensed MIT. It adds 41 tokens to every session and 1,427 once invoked, about $0.0002 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 2026-08-31.
