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 | $0.00693 |
| Opus 5 | $0.00000 | $0.00347 |
| Sonnet 5 | $0.00000 | $0.00139 |
| Haiku 4.5 | $0.00000 | $0.00069 |
Grade A, and why
testing-coverage scanned grade A with 1 finding 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 9d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
! curl -s http://localhost:11434/api/tags >/dev/null 2>&1 && \ How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: gga-testing-coverage
Purpose
Ensure test coverage for all behavior changes in GGA.
When to Use
When implementing behavior changes in any script (bin/gga, lib/*.sh).
Framework
ShellSpec — https://shellspec.info/
Test Structure
spec/
├── unit/ # Isolated function tests (no external calls)
│ ├── cache_spec.sh
│ └── providers_spec.sh
├── integration/ # Full command + hook + CI mode tests
│ └── commands_spec.sh
├── support/ # Shared helpers, fixtures
└── spec_helper.sh # Global setup
Unit tests → test functions in lib/cache.sh, lib/providers.sh in isolation.
Integration tests → test gga CLI commands, hook injection, CI mode end-to-end.
Running Tests
| Command | What It Does |
|---|---|
make test |
Run all tests |
shellspec spec/unit |
Unit tests only |
shellspec spec/integration/commands_spec.sh |
Integration tests only |

Critical Rules
- Every feature or bug fix MUST include tests — no exceptions
- Use
setup/cleanupblocks with temp dirs for test isolation - Mock external commands (providers, git) in unit tests — never call real providers
- Ollama tests skip automatically when no server is running (use
skip_if_no_ollama) - Run
make testbefore every push
ShellSpec Patterns
# Basic structure
Describe 'function_name'
setup() { ... }
cleanup() { ... }
It 'does something'
When call function_name arg
The status should be success
The output should include "expected"
End
End
# Custom assertion (use Assert for comparisons, not bare The status)
It 'returns a count less than 10'
When call get_count
The output should be present
Assert [ "$(get_count)" -lt 10 ]
End
# Skip conditionally
skip_if_no_ollama() {
! curl -s http://localhost:11434/api/tags >/dev/null 2>&1 && \
skip "Ollama not running"
}
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.

testing-coverage is a skill published in the GitHub repository Gentleman-Programming/gentleman-guardian-angel (1,145 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 693 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
