At a glance

A skill your agent uses when creating or modifying GitHub Actions workflow files.

  • Modifying GitHub Actions workflow files
  • SKILL.md covers Workflow File Structure, Workflow Triggers, Job Configuration and Steps, plus 4 more sections
  • Needs GITHUB_TOKEN and API_KEY
  • Tasks that involve CI/CD

What it does

Act Workflow Syntax is an agent skill from TheBushidoCollective/han. Use when creating or modifying GitHub Actions workflow files. Provides guidance on workflow syntax, triggers, jobs, steps, and expressions for creating valid GitHub Actions workflows that can be tested locally with act.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering CI/CD. It works with GitHub Actions. The repository describes itself as: A curated marketplace of Claude Code plugins that embody the principles of ethical and professional software development.

When your agent uses it

  • Modifying GitHub Actions workflow files
  • Tasks that involve CI/CD

Example prompts

  • “/act-workflow-syntax”

Requirements

  • Node.js
  • Docker
  • A credential in GITHUB_TOKEN
  • A credential in API_KEY
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep, Glob

What it can do on your machine

Read from SKILL.md and the folder at commit 19caa51. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • Grep
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • GITHUB_TOKEN
    • API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Act Workflow Syntax loads about 2k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 266 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Bash, Grep, Glob

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 266 words (~1,994 tokens).

“Use this skill when creating or modifying GitHub Actions workflow files (.github/workflows/*.yml). This covers workflow structure, triggers, jobs, steps, and best practices for workflows that work both on GitHub and locally with act.”
