review-agentic-workflows

A review guide for agentic GitHub workflows—automated workflows that use AI agents—and their generated lock files. It focuses on correctness, security, validation, and runtime evidence.

In plain words
What is it for?
Use it to review workflow diffs, run compilation and security checks, inspect run history, and identify optimization opportunities.
Why use it?
It helps find unsafe workflow changes and confirms that modified workflows compile and pass available checks.

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

review-agentic-workflows 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 yesterday.

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.

Review Agentic Workflows

Use this skill when asked to review .github/workflows/*.md agentic workflows or their generated .lock.yml outputs. Reference workflow authoring skill guidance at: https://raw.githubusercontent.com/github/gh-aw/main/.github/skills/agentic-workflows/SKILL.md

Goals

  1. Produce a security-first review of workflow changes.
  2. Compile workflows with validation and security scanners.
  3. Flag suspicious changes that weaken protections.
  4. Use run history (logs/audit) when available to find optimization opportunities.

Self-contained setup (do not assume environment is ready)

Step 0) Verify CLI availability

Run from the repository root:

if gh aw --help >/dev/null 2>&1; then
  echo "gh aw is installed"
else
  if [ -f ./install-gh-aw.sh ]; then
    echo "gh aw is missing. Run the install step before continuing:"
    echo "  bash ./install-gh-aw.sh"
    echo "Then verify:"
    echo "  gh aw --help"
  else
    echo "gh aw is missing and ./install-gh-aw.sh is not present in this checkout."
  fi
  return 1 2>/dev/null || exit 1
fi

Review workflow

1) Scope the review

Run this scope check in the review step:

BASE_REF="${BASE_REF:-origin/main}"
if git rev-parse --verify "$BASE_REF" >/dev/null 2>&1; then
  git diff --name-only "$BASE_REF...HEAD" -- .github/workflows/
else
  git diff --name-only -- .github/workflows/
fi

If source .md files changed, treat generated .lock.yml drift as part of the review.

2) Compile with validation + security tools

For changed workflows, run strict compilation with validators:

gh aw compile --strict --actionlint --zizmor --poutine --runner-guard --yamllint --shellcheck

If gh aw extension is unavailable but local binary exists:

./gh-aw compile --strict --actionlint --zizmor --poutine --runner-guard --yamllint --shellcheck

Fail review on compilation errors or High/Critical security findings unless explicitly justified.

3) Enforce security best practices

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.

review-agentic-workflows is a skill published in the GitHub repository github/gh-aw (5,050 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 936 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
