Audits GitHub Actions workflows for security vulnerabilities in AI agent integrations including Claude Code Action, Gemini CLI, OpenAI Codex, and GitHub AI Inference. Detects attack vectors where attacker-controlled input reaches AI agents running in CI/CD pipelines.
Why this skill is useful
Adds a comprehensive static analysis methodology for auditing AI agent integrations in GitHub Actions workflows, including specific attack vectors and security configurations not commonly known.

What this skill does
Supporting material availability This AAS tree bundles the inline methodology only. The contributed guide named a foundations file, action profiles, cross-file resolution and nine vector reference files, but those files and an independently verified upstream source are absent. Do not claim they were read. Apply the inline checks below and report unsupported action-version details as unverified; recover external materials only from a verified source with a confirmed license. 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 (pullrequesttarget, issuecomment, 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 file …
