agentic-actions-auditor

agentic-actions-auditor is a skill for Claude Code from satnamrsm/https-github.com-sickn33-antigravity-awesome-skills. It costs 57 tokens per session (4,583 once invoked), scanned A, a copy of agentic-actions-auditor, MIT.

A security-review guide for GitHub Actions workflows that run AI coding agents. GitHub Actions is GitHub's system for automatically running build, test, and deployment jobs.

In plain words
What is it for?
Use it to inspect workflows invoking Claude Code, Gemini CLI, OpenAI Codex, or GitHub AI Inference, trace inputs across reusable workflows and actions, and review permissions, sandboxes, and triggers.
Why use it?
It helps find ways that attacker-controlled pull requests, issues, or other event data could influence an AI agent running in CI/CD.

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

agentic-actions-auditor 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 6d 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.

Agentic Actions Auditor

Static security analysis guidance for GitHub Actions workflows that invoke AI coding agents. This skill teaches you how to discover workflow files locally or from remote GitHub repositories, identify AI action steps, follow cross-file references to composite actions and reusable workflows that may contain hidden AI agents, capture security-relevant configuration, and detect attack vectors where attacker-controlled input reaches an AI agent running in a CI/CD pipeline.

When to Use

  • Auditing a repository's GitHub Actions workflows for AI agent security
  • Reviewing CI/CD configurations that invoke Claude Code Action, Gemini CLI, or OpenAI Codex
  • Checking whether attacker-controlled input can reach AI agent prompts
  • Evaluating agentic action configurations (sandbox settings, tool permissions, user allowlists)
  • Assessing trigger events that expose workflows to external input (pull_request_target, issue_comment, etc.)
  • Investigating data flow from GitHub event context through env: blocks to AI prompt fields

When NOT to Use

  • Analyzing workflows that do NOT use any AI agent actions (use general Actions security tools instead)
  • Reviewing standalone composite actions or reusable workflows outside of a caller workflow context (use this skill when analyzing a workflow that references them via uses:)
  • Performing runtime prompt injection testing (this is static analysis guidance, not exploitation)
  • Auditing non-GitHub CI/CD systems (Jenkins, GitLab CI, CircleCI)
  • Auto-fixing or modifying workflow files (this skill reports findings, does not modify files)

Rationalizations to Reject

When auditing agentic actions, reject these common rationalizations. Each represents a reasoning shortcut that leads to missed findings.

1. "It only runs on PRs from maintainers" Wrong because it ignores pull_request_target, issue_comment, and other trigger events that expose actions to external input. Attackers do not need write access to trigger these workflows. A pull_request_target event runs in the context of the base branch, not the PR branch, meaning any external contributor can trigger it by opening a PR.

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.
