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

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.

Origin

This is a copy

88% identical to git-commit — 39 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 — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git Commit

Creates git commits following Conventional Commits format with proper type, scope, and subject.

Quick Start

# 1. Stage changes
git add <files>  # or: git add -A

# 2. Create commit (branch commit format)
git commit -m "type(scope): subject

Body explaining HOW and WHY.
Reference: Task X.Y, Req N"

Commit Types

Regular Branch Commits (During Development)

Format: type(scope): subject

Type Purpose
feat New feature or functionality
fix Bug fix or issue resolution
refactor Code refactoring without behavior change
perf Performance improvements
test Test additions or modifications
ci CI/CD configuration changes
docs Documentation updates
chore Maintenance, dependencies, tooling
style Code formatting, linting (non-functional)
security Security vulnerability fixes or hardening

Scope (Required, kebab-case)

Examples: validation, auth, cookie-service, template, config, tests, api

Subject Line Rules

  • Max 50 characters after colon
  • Present tense imperative: add, implement, fix, improve, enhance, refactor, remove, prevent
  • NO period at the end
  • Specific and descriptive - state WHAT, not WHY

Core Workflow

1. Review Changes

git status
git diff --staged  # if already staged
git diff           # if not staged

2. Stage Files

git add <specific-files>  # preferred
# or
git add -A  # all changes

NEVER commit:

  • .env, credentials.json, secrets
  • node_modules/, __pycache__/, .venv/
  • Large binary files without explicit approval

3. Create Commit

Simple change:

git commit -m "fix(auth): use hmac.compare_digest for secure comparison"

Complex change (with body):

git commit -m "$(cat <<'EOF'
feat(validation): add URLValidator with domain whitelist

Implement URLValidator class supporting:
- Domain whitelist enforcement (youtube.com, youtu.be)
- Dangerous scheme blocking (javascript, data, file)
- URL parsing with embedded credentials handling

Addresses Requirement 31: Input validation
Part of Task 5.1: Input Validation Utilities

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
