Stop hand-crafting YAML. Let any AI agent generate production-ready workflows with 12 quality gates, 5 decision templates, and 3 mandatory security configs.

Hand-writing GitHub Actions YAML is error-prone. Did you remember `permissions`

? Did you pin action versions? Did you configure caching? Is concurrency set?

Every omitted config is either slower builds, security holes, or wasted billable minutes.

I built an **AI Skill** — an executable instruction set, not a vague prompt. It forces any AI agent to follow a strict pipeline:

```
Decision Tree → Mandatory Config Injection → Cache Matching → 12 Quality Gates → Production YAML
```

"Add CI for my Node.js project — run eslint and jest on PRs"

**What the AI generates under the hood:**

`package.json`

→ Node.js`permissions: contents: read`

injected`concurrency`

with auto-cancel`cache: 'npm'`

→ ~70% faster installs`@11bd71...`

not `@v4`

)**5 seconds. Zero omissions.**

| Approach | Universal | Security Check | Caching | Quality Gates |
|---|---|---|---|---|
| GitHub templates | ✅ | ❌ | ❌ | ❌ |
| Manual YAML | ✅ | ❌ | ❌ | ❌ |
| Raw ChatGPT prompt | ✅ | ❌ | ❌ | ❌ |
This Skill |
✅ All agents | ✅ 5 red lines | ✅ 6 langs | ✅ 12 gates |

Raw LLM chats miss configs every time. This Skill makes them **mandatory**, not optional.

Every template enforces **least-privilege permissions, concurrency control, and SHA-1 pinned actions** — no exceptions.

`pull_request_target`

misuse → blocked`@main`

/ `@master`

action refs → blocked`permissions: write-all`
