repo-security-posture

repo-security-posture is a skill for Claude Code, Codex from superagent-ai/skills. It costs 125 tokens per session (1,740 once invoked), scanned A, original, MIT.

A security review for a GitHub repository, including its branch rules, code ownership files, automated workflows, release process, collaborators, and dependency checks.

In plain words
What is it for?
Use it to produce a ranked list of specific hardening tasks for repository access, pull requests, GitHub Actions, releases, security settings, and dependencies.
Why use it?
It focuses the review on realistic ways a stolen account, contributor, or repository permission could be used to alter code or publish something harmful.

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

repo-security-posture 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/collect.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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repository Security Posture

Audit a repository's configuration and CI/CD against a set of concrete attacker scenarios, then hand the maintainer a ranked list of hardening todos. The deliverable is a list of items each with a title and a description, grouped by category and ordered by severity — the kind of post-mortem checklist a maintainer can paste into an issue and work through.

The job is not to dump every theoretical best practice. It is to look at this repo, find the gaps an attacker would actually use, and write todos that are specific to what was found (or specific about what couldn't be verified).

Threat model

Every finding should trace back to at least one of these scenarios. Naming the scenario in the description is what makes a todo land — it tells the maintainer why it matters, not just what to toggle.

  1. Compromised contributor — a trusted contributor's account, laptop, or token is taken over (phishing, malware, leaked PAT). What stops them from merging or publishing malicious code alone?
  2. Attacker with repo write access — an outside attacker gains push or admin rights. What limits blast radius, what can they exfiltrate, and how fast can the maintainer rotate and recover?
  3. CI/CD compromise — a malicious PR, poisoned cache, or injected workflow turns the build pipeline into the attack. GitHub Actions is the most common modern repo-takeover path.
  4. Registry / publish supply chain — the repo is fine but a bad version ships to npm/PyPI/etc. via a stolen publish token or an unreviewed release job. This is the @mastra / dotenvx / TeamPCP class of incident.

Workflow

1. Identify the target and gather evidence

Resolve the repo to owner/name. If the user gave a URL, parse it. If they named a repo you can't pin down, ask.

Run the collector to pull configuration and files into a single JSON inventory:

# A token dramatically expands what's visible (branch protection, actions
# permissions, security features, collaborators, hooks). Set it if available.
export GITHUB_TOKEN=...   # optional but strongly recommended
python3 scripts/collect.py owner/name --output /tmp/audit.json

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.
