github-actions-workflow

A workflow for creating or reviewing GitHub Actions, which are automated jobs that run tasks such as linting and tests when code changes. It adapts the setup to the project’s language, package manager, commands, and deployment target.

In plain words
What is it for?
Use it to set up or audit continuous integration and delivery, including lint and test jobs, dependency caching, secrets, concurrency, environment approvals, and reusable workflows.
Why use it?
It helps keep code checks consistent and can reduce wasted build time through caching and cancellation of outdated runs.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-workflow 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.

How it starts

The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Actions Workflow Skill

Step 1 — Detect Project Type

Identify the runtime and package manager before scaffolding:

  • Language (Go, TypeScript/Node, Python, PHP, …)
  • Package manager (pnpm, npm, Go modules, uv, Composer)
  • Test and lint commands (from justfile, Makefile, or package.json)
  • Deploy targets (container registry, cloud provider, static host)

Step 2 — Scaffold .github/workflows/ci.yml

name: CI

on:
  push:
    branches: [main]
  pull_request:

concurrency:
  group: ci-${{ github.ref }}
  cancel-in-progress: true

jobs:
  lint:
    name: Lint
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Set up runtime
        uses: <runtime-setup-action>   # e.g. actions/setup-go@v5
        with:
          <version-key>: <version>     # e.g. go-version: "1.23"
      - name: Cache dependencies
        uses: actions/cache@v4
        with:
          path: <cache-path>
          key: ${{ runner.os }}-<tool>-${{ hashFiles('<lockfile>') }}
      - name: Install dependencies
        run: <install-command>
      - name: Lint
        run: <lint-command>

  test:
    name: Test
    runs-on: ubuntu-latest
    needs: lint
    steps:
      - uses: actions/checkout@v4
      - name: Set up runtime
        uses: <runtime-setup-action>
        with:
          <version-key>: <version>
      - name: Cache dependencies
        uses: actions/cache@v4
        with:
          path: <cache-path>
          key: ${{ runner.os }}-<tool>-${{ hashFiles('<lockfile>') }}
      - name: Install dependencies
        run: <install-command>
      - name: Test
        run: <test-command>

  build:
    name: Build
    runs-on: ubuntu-latest
    needs: test
    steps:
      - uses: actions/checkout@v4
      - name: Build
        run: <build-command>

Step 3 — Job Structure

Job Depends on Purpose
lint Fail fast on code quality issues
test lint Run unit and integration tests
build test Verify the artefact compiles/bundles
deploy build Push to environment (conditionally)

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.

github-actions-workflow is a skill published in the GitHub repository soulcodex/agentic (10 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 1,769 once invoked, about $0.0004 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 2026-08-31.
