git

A set of rules for recording code changes with Git, a tool for tracking versions of files and collaborating on code. It covers branch names, commit messages, pull-request review, and related safeguards.

In plain words
What is it for?
It helps create branches, write commits using Conventional Commits, open or review pull requests, and record breaking changes.
Why use it?
It prevents inconsistent change records and unsafe repository practices, such as pushing directly to the main branch or using unclear commit messages.

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

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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git

How change is recorded.

Workflow

  1. Work on the branch defined for the task at hand. Never push directly to main.
  2. Create new commits rather than amending. Never force-push or skip hooks without explicit permission.
  3. Task PRs target their milestone branch; milestone PRs target the latest main. Work outside a milestone stays on a feature branch and PRs only when explicitly asked.

Conventional Commits

  1. All commit subjects follow Conventional Commits:

    <type>(<optional scope>): <imperative summary>
    
    • Allowed types: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert.
    • Scopes match the affected area: the surface (home), the layer (templates, tokens, constants), or the docs (prd, docs). Omit when global.
    • Subject: ≤ 72 characters, lowercase, no trailing period.
    • Body: explain the why when the diff alone doesn't.
    • Breaking changes: ! suffix and a BREAKING CHANGE: footer for route moves, renames, or behavior changes.

Branch naming

  1. Branches follow the same type vocabulary as commits:

    <type>/<short-kebab-summary>
    
    • ≤ 40 characters, lowercase, hyphen-separated.
    • Milestone and task branches carry their identifiers: feat/m02-works, feat/m02-t04-works-ledger.
    • Branches outside a milestone reference the affected area: fix/date-zoning, docs/initial-plan.

Attribution

  1. No AI/agent attribution in commits, PRs, or issues: no Co-Authored-By: Claude/Codex, no "Generated with Claude Code" markers, no claude.ai/code session links.

Review

  1. Read the project's own vendored skills before reviewing the diff. Skills under .claude/skills/ / .agents/skills/ are that project's actual, current standards, not generic advice; load the ones relevant to the changed files (components for a component diff, data for a constants/data change, nextjs for routing, etc.) and check the diff against what they specifically say before reaching for anything else.
  2. Then apply conventional best practice: correctness, security, performance, test coverage, readability — the concerns a project's skills don't cover because they're universal rather than project-specific.
  3. A skill deviation is a finding on its own, distinct from a generic style nit: name the skill and the rule it violates, not just "this looks off."
  4. When a project has no vendored skills, or the change touches an area none of them cover, fall back to conventional best practice alone — don't invent a project standard that isn't written down anywhere.

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 techtankto/techtank-site (5 stars, last pushed 6d ago), licensed MIT. It adds 58 tokens to every session and 732 once invoked, about $0.0003 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.
