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 5.1 | $0.00073 | $0.00997 |
| Opus 5.5 | $0.00029 | $0.00399 |
| Sonnet 5.5 | $0.00015 | $0.00199 |
| Haiku 4.5 | $0.00007 | $0.00100 |
Grade A, and why
setup-pre-commit 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.
This is a copy
100% identical to setup-pre-commit — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Detect the ecosystem, pick the right hook tool, install with formatter + type-check + test gates.
Detection (run first)
Dispatch Explore agent — or for a single-language repo, probe directly via fd for lockfile / manifest signature. Map the first manifest hit to an ecosystem. Multi-language repos: ask the maintainer which surface to gate, or apply both.
Ecosystem → hook tool
| Ecosystem | Hook tool | Install command |
|---|---|---|
| npm / yarn / pnpm / bun | husky + lint-staged | <pm> add -D husky lint-staged prettier && npx husky init |
| Python (poetry/pip) | pre-commit (framework) | pipx install pre-commit && pre-commit install |
| Go | lefthook (or pre-commit) | go install github.com/evilmartians/lefthook@latest && lefthook install |
| Rust (cargo) | cargo-husky (or pre-commit) | add cargo-husky as [dev-dependencies]; runs on cargo test |
| OCaml (dune) | pre-commit + dune hooks | pipx install pre-commit && pre-commit install |
Per-ecosystem hook contents
Node ecosystems — write .husky/pre-commit:
npx lint-staged
<pm> run typecheck
<pm> run test
Drop missing scripts and tell the user. Write .lintstagedrc:
{ "*": "prettier --ignore-unknown --write" }
Formatter policy is out of scope for this skill. Do NOT auto-create .prettierrc. If no Prettier config exists, surface that fact and ask the user.
Python — write .pre-commit-config.yaml:
repos:
- repo: https://github.com/astral-sh/ruff-pre-commit
rev: v0.6.0
hooks:
- id: ruff
- id: ruff-format
- repo: local
hooks:
- id: pyright
name: pyright
entry: pyright
language: system
pass_filenames: false
- id: pytest
name: pytest
entry: pytest -q
language: system
pass_filenames: false
stages: [pre-commit]
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.

setup-pre-commit is a skill published in the GitHub repository OutlineDriven/odin-gemini-cli-extension (4 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 73 tokens to every session and 997 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to setup-pre-commit, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
request-refactor-plan
Plan a refactor as a sequence of tiny, working commits via adversarial interview. Default output is a markdown plan at /docs/refactor-plans/ .md; pass --emit-issue to also file a GitHub issue. Trigger on structural refactors (rename, extract, move, split, dedupe) — NOT new features.
setup-pre-commit
Install git pre-commit hooks via the project's hook tool — Husky+lint-staged (JS), pre-commit (Python/OCaml), lefthook (Go), cargo-husky (Rust). Use when the user wants commit-time formatting, linting, type-checking, or test gates. Detects ecosystem first.
atomic-commit-and-push
Run the atomic-commit workflow on the current changes, then publish the resulting commits to the remote. Use whenever the user says "commit and push", "ship these changes", "atomic commit and push", "publish my work", or wants atomic commits delivered to origin in one step. Prefers git submit (git-branchless); falls…
atomic-commit
Review staged + unstaged changes and split them into one commit per logical change. Use whenever the user says "atomic commit", "commit my changes", "split this into commits", or has multiple unrelated edits sitting in the working tree — even if they don't say "atomic". Runs repo-native type-checker and linter before…
git-branchless
Enforce idiomatic git-branchless during planning and executing tasks — detached-HEAD-first work, in-memory rebase via git move, event-log recovery via git undo, deferred branch creation, speculative-merge git sync for base updates. Use when planning or executing multi-commit work, history rewrites, stack edits…
qa
Conversational QA mode — user reports bugs in plain language, agent clarifies minimally, files GitHub issues that survive refactors. Trigger on "QA", "QA session", or ad-hoc bug reporting without a fixed deliverable shape. Distinct from branch-scoped and PR-scoped review.
