These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

github 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 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.

How it starts

The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Skill

Full GitHub operations via the gh CLI. Always check auth first, use templates for consistency, and respect rate limits.

Step 0: Auth Detection (ALWAYS FIRST)

Before ANY GitHub operation, detect the auth method:

gh auth status 2>&1

If authenticated: Proceed. Note the logged-in username for the session.

If not authenticated: Check for GITHUB_TOKEN env var:

echo "${GITHUB_TOKEN:+token_set}"

If no token either: Tell the user:

GitHub CLI is not authenticated. Run gh auth login to authenticate, or set GITHUB_TOKEN environment variable with a personal access token.

Do NOT proceed without auth. Do NOT fall back to curl or http_request.

Step 1: Rate Limit Check (before bulk operations)

Before operations that issue 5+ API calls (batch triage, bulk label, multi-issue create), check rate limits:

gh api rate_limit --jq '.resources.core.remaining, .resources.core.limit, .resources.search.remaining, .resources.search.limit'

If core remaining < 100 or search remaining < 10, warn the user and ask whether to proceed.

Issue Operations

Create Issue

gh issue create --repo OWNER/REPO --title "TITLE" --body "BODY" --label "LABEL" --assignee "USER"

Templates (use unless user provides their own):

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.

github is a skill published in the GitHub repository adolfousier/opencrabs (970 stars, last pushed 13d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,580 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.
