gitgauge

A GitHub repository checker that scores how authentic a repository appears. A repository is a project hosted on GitHub, and the tool follows the scoring method used by the GitGauge browser extension.

In plain words
What is it for?
It helps assess a full GitHub repository URL, show a score and breakdown, and flag signs that may affect the repository’s apparent authenticity.
Why use it?
It gives a quick credibility signal before an agent spends time reviewing or using a repository.

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.

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

gitgauge 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/score.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

GitGauge

Score GitHub repos for authenticity. Mirrors the GitGauge Chrome extension algorithm exactly.

The GitGauge output line is the announcement — no separate announce needed. Run the scorer first, then engage with the repo.

When to run

Trigger Output mode
GitHub URL appears passively in conversation Compact one-liner, then continue
User asks to review / analyze a repo Compact score + brief breakdown, then review
User runs /gitgauge owner/repo Full report: sub-scores, flags, metadata

Do not run on:

  • GitHub profile URLs, org pages, gist links, issue links, PR links, or commit links
  • npm package references (@scope/package), file paths, or bare owner/repo with no GitHub URL context
  • Repos already scored in the current conversation

Running the scorer

python ~/.claude/skills/gitgauge/scripts/score.py owner/repo
# macOS / Linux: use python3 instead of python

With a token (removes rate limit):

python ~/.claude/skills/gitgauge/scripts/score.py owner/repo --token ghp_yourtoken

For the full report mode (parse JSON to build structured output):

python ~/.claude/skills/gitgauge/scripts/score.py owner/repo --json

Pass full GitHub URLs too — the script strips the github.com/ prefix automatically.

Output formats

Compact (passive trigger)

Files

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.
