security-baseline-review

security-baseline-review is a skill for Claude Code, Codex from stark-ai-de/agent-skills. It costs 49 tokens per session (579 once invoked), scanned A, original, Apache-2.0.

A baseline check of a public software repository's security housekeeping. It looks at exposed secrets, dependencies, automated workflows, reporting instructions, and repository settings.

In plain words
What is it for?
Use it to review secret-handling files, dependency update practices, CI permissions, pull-request safety, SECURITY.md, branch-protection notes, and the boundary between public and private data.
Why use it?
It helps find common release risks before publication without claiming to be a full security audit or trying to exploit the code.

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

security-baseline-review 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.

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.

Security Baseline Review

Goal

Review a public repository for baseline security hygiene without exploiting systems, exposing sensitive data, or overclaiming vulnerability status.

When to use

  • The user asks for a public repo security readiness check.
  • Secret hygiene, CI permissions, dependency policy, or SECURITY.md needs review.
  • A repository is about to be published.

When not to use

  • The user asks for exploit development or offensive instructions.
  • A full code vulnerability audit is required beyond maintainer hygiene.
  • Current CVE status is required but live advisory data is unavailable.

Inputs to inspect

  • .gitignore, .env.example, config samples, workflows, SECURITY.md, README, and contribution docs.
  • Dependency manifests, lockfiles, and update automation config.
  • Repository settings checklist when live GitHub access is authorized.

Review rubric

Check obvious secret patterns, sensitive examples, CI permissions, untrusted pull request behavior, dependency update policy, security reporting path, branch protection notes, and public/private boundary clarity. Read references/security-checklist.md for detail.

Workflow

  1. Inspect public-facing files and config examples.
  2. Search for obvious secret-like patterns without printing sensitive values.
  3. Review workflow permissions and risky shell patterns.
  4. Check dependency and security policy coverage.
  5. Recommend safer defaults and rotation if exposure is suspected.
  6. Separate confirmed issues from items requiring live repository settings.

Safety rules

  • Do not print suspected secret values.
  • Do not provide exploit instructions or proof-of-concept attack steps.
  • Recommend rotation before history cleanup when exposure is plausible.

References

Read only when needed:

  • references/security-checklist.md

Scripts

No bundled scripts.

Output format

Return:

  1. Baseline verdict
  2. Critical findings
  3. High-priority findings
  4. Medium or policy findings
  5. Settings to verify live
  6. Recommended next action

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.
