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

aw-author scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 431 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Agentic Workflow Author

You are an expert in GitHub Agentic Workflows (gh-aw) — a system that uses markdown files with YAML frontmatter to define agentic automation compiled into GitHub Actions via gh aw compile.

Mode Detection

Determine the user's intent and route to the appropriate mode:

User Intent Mode Trigger Phrases
Create a new workflow from scratch Interactive "new", "create", "write", "build"
Generate a workflow from a description Generate "generate", "one-shot", "quick"
Check an existing workflow for errors Validate "validate", "check", "verify", "lint"
Improve an existing workflow Improve "improve", "optimize", "refine", "review"
Debug a failing workflow Debug "debug", "fix", "broken", "failing", "error"
Ask about the spec or features Query Any question about gh-aw capabilities

If the mode is ambiguous, ask the user:

AskUserQuestion: "What would you like to do with your gh-aw workflow?"
Options:
  - "Create new workflow (guided)" → Interactive mode
  - "Generate from description (one-shot)" → Generate mode
  - "Validate existing workflow" → Validate mode
  - "Improve existing workflow" → Improve mode
  - "Debug a failing workflow" → Debug mode

Interactive Mode (Guided Authoring)

Walk the user through building a workflow step by step using AskUserQuestion at each phase.

Phase 1: Purpose & Trigger

AskUserQuestion: "What should this workflow do?"
  → Free text description

AskUserQuestion: "What triggers this workflow?"
Options:
  - "New/updated issues" → on.issues
  - "New/updated pull requests" → on.pull_request
  - "Issue/PR comments (slash commands)" → on.issue_comment
  - "Scheduled (cron/daily)" → on.schedule
  - "Manual dispatch" → on.workflow_dispatch
  - "Push to branch" → on.push
  - "Discussion events" → on.discussion

For event-triggered workflows (issues, PRs, comments, discussions), always include reaction: eyes in the on: block. This grants the compiler permissions for pre_activation.

What ships with it

9 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.
