Gentleman Guardian Angel is an AI code-review tool that checks staged files against a repository’s coding standards. Developers use it as a Git pre-commit hook or to review full pull requests, with different AI providers available. The catalogue add-ons support its workflows.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00602 |
| Opus 5.5 | $0.00000 | $0.00241 |
| Sonnet 5.5 | $0.00000 | $0.00120 |
| Haiku 4.5 | $0.00000 | $0.00060 |
Grade A, and why
commit-hygiene 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 2mo 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: gga-commit-hygiene
Purpose
Enforce conventional commits and a clean, readable history for GGA.
When to Use
Any commit creation, review, or branch cleanup.
Format
type(scope): description
Validated by regex:
^(build|chore|ci|docs|feat|fix|perf|refactor|revert|style|test)(\([a-z0-9\._-]+\))?!?: .+
Valid Types
| Type | Use For |
|---|---|
| feat | New feature or behavior |
| fix | Bug fix |
| docs | Documentation only |
| chore | Maintenance, dependencies, tooling |
| refactor | Restructuring without behavior change |
| test | Adding or fixing tests |
| ci | CI/CD pipeline changes |
| style | Formatting, whitespace, no logic change |
| perf | Performance improvement |
| build | Build system, Makefile changes |
| revert | Reverting a previous commit |
Valid Scopes for GGA
| Scope | Covers |
|---|---|
| providers | lib/providers.sh, any AI provider integration |
| hooks | Hook system, marker injection, pre-commit logic |
| cache | lib/cache.sh, hash logic |
| cli | bin/gga flags, argument parsing, output |
| ci | GitHub Actions workflows |
| config | .gga config file parsing |
| install | install.sh, uninstall.sh |
Critical Rules
- NEVER add
Co-Authored-Byor any AI attribution trailers - One logical change per commit — no "add X and fix Y and update docs"
- Use imperative mood: "add" not "added", "fix" not "fixed"
- Reference issue numbers when relevant:
feat(providers): add GitHub Models support (#12) - Keep subject line ≤ 72 characters
- If a commit needs explanation, add a body separated by a blank line
Examples
feat(providers): add GitHub Models provider support
fix(hooks): resolve marker injection in existing hooks
fix(cache): handle hash collision on empty files
test(cache): add unit tests for hash invalidation
test(hooks): add integration tests for marker injection
refactor(cli): extract provider dispatch to lib/providers.sh
ci: split unit and integration test jobs
docs(contributing): add label system documentation
chore: update shellspec to 0.28.1
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.

commit-hygiene is a skill published in the GitHub repository Gentleman-Programming/gentleman-guardian-angel (1,192 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 602 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.
