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 | $0.00020 | $0.00635 |
| Opus 5 | $0.00010 | $0.00318 |
| Sonnet 5 | $0.00004 | $0.00127 |
| Haiku 4.5 | $0.00002 | $0.00064 |
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 2d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<repository_rules> Check for the followings for repository specific rules and instructions related to git names/messages conventions and workflows:
- AGETNS.md
- CLAUDE.md
- .agents/
Merge them with the general instructions below, with repository rules taking precedence in case of conflict. </repository_rules>
Commit
Commit message format:
<type>[scope]: <description>
<optional body>
<optional footer>
Rules
- One logical change per commit, if many files changed, create multiple commits with clear scope and messages
- Present tense: "add" not "added"
- Imperative mood: "fix bug" not "fixes bug"
- Reference issues:
Closes #123,Refs #456 - Keep description under 72 characters
- NEVER update git config
- NEVER run destructive commands (
--force, hard reset) without explicit request - NEVER skip hooks (
--no-verify) unless user asks - NEVER force push unless the user explicitly requests it
- NEVER commit to
master/mainunless repository rules allow it and the user confirms it
Branch
Branch naming format: {type}/{semantic-name}
Rules
- NEVER delete or rename existing branches without explicit user request
- NEVER force-push or reset master/main
- NEVER run destructive commands without confirmation
- If branch already exists, report this to the user and ask how to proceed
Pull Request
Title format: {type}[scope]: {description}
Description format:
## Summary
{1–3 sentences explaining what this PR does and its scope}
## Changes
- {key change 1, do not repeat file changes, focus on observable behavior changes}
- {key change 2, do not repeat file changes, focus on observable behavior changes}
- {more as needed — keep each bullet atomic and concrete}
## Why
{motivation: what problem does this solve, or what goal does it achieve.}
## Breaking Changes
{describe what breaks and how consumers should migrate. Omit if no breaking 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.

git is a skill published in the GitHub repository SNIKO/agent-skills (2 stars, last pushed 10d ago), licensed MIT. It adds 20 tokens to every session and 635 once invoked, about $0.0001 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.
