pre-commit-setup

Instructions for setting up pre-commit checks that inspect code before a commit is created. They cover formatting, linting, type checking, and Lizard, a tool that measures code complexity across programming languages.

In plain words
What is it for?
Configuring pre-commit hooks for Python, TypeScript, JavaScript, Go, Rust, C/C++, and Java projects, including the appropriate linters, formatters, type checkers, and complexity limits.
Why use it?
It catches style, type, and overly complicated code before changes reach the repository. This makes quality checks automatic and consistent across different languages.

Token cost

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.

Security

Grade A, and why

pre-commit-setup 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.

Контекст

Настройка pre-commit хуков для проверки кода перед commit. Включает linter, formatter, complexity check.

pip install lizard  # или uv pip install lizard
lizard -l 15 -n 300 -a 10 <dir>

Ориентиры: complexity ≤ 15, NLOC ≤ 300, параметры ≤ 10.

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.

pre-commit-setup is a skill published in the GitHub repository kissrosecicd-hub/agents-evolution (31 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,134 tokens. 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.
