github-actions-reviewer

github-actions-reviewer is a skill for Claude Code from infraspecdev/tesseract. It costs 43 tokens per session (858 once invoked), scanned A, original, MIT.

A review workflow for GitHub Actions, the automation system built into GitHub repositories. It examines all workflows together because their settings and assumptions can affect one another.

In plain words
What is it for?
Auditing existing GitHub Actions workflows, checking their consistency and security, and producing an analysis and improvement plan.
Why use it?
It helps uncover inconsistent action versions, unsafe permissions, missing controls for overlapping runs, and incomplete file or path filters that can cause security or CI problems.

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-actions-reviewer 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 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.

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.

GitHub Actions Reviewer

Overview

Structured review of GitHub Actions workflows for consistency, security, and operational best practices.

Core principle: Workflows in the same repo form a system. Review them as a group, not individually — inconsistencies between workflows cause the hardest-to-debug CI failures.

When to Use

  • Reviewing CI/CD workflows in any repository
  • Auditing workflow permissions and security posture
  • Checking for version drift across workflows
  • After adding a new workflow to verify consistency with existing ones
  • Periodic hygiene check on GitHub Actions setup
  • Re-grading after improvements (creates fresh analysis and plan)

When NOT to Use

  • Debugging a single workflow run failure (use GitHub's run logs instead)
  • Writing new workflows from scratch (this skill reviews existing ones)
  • Non-GitHub CI systems (Jenkins, GitLab CI, CircleCI)
  • Reviewing application code that happens to be triggered by workflows

Workflow

Read All Workflows + Config -> Evaluate Against Checklist -> Write analysis.md -> Write plan.md -> Ask User to Confirm -> (proceed: Execute / stop: Done / edit: revise plan.md)

Critical Rules

  1. ALWAYS write analysis.md and plan.md — Even on re-reviews or when no issues found. Never skip file output.
  2. ALWAYS ask user before executing — Never auto-proceed to implementation.
  3. Show the user what was written — Summarize key findings after writing files.

Steps

1. Read All Workflows and Config

Read every file in .github/workflows/ plus related config: release tooling configs (release-please-config.json, .releaserc.json, etc.), versions.tf, .tflint.hcl, package.json.

2. Evaluate Against Checklist

Run through the 8-point checklist covering version consistency, plugin/config alignment, permissions, concurrency control, path filters, reusable patterns, action pinning, and secrets handling. See checklist.md for detailed criteria, examples, and red flags.

3. Write analysis.md

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
