# GitHub Actions SHA Reference Skill

## 目的

このスキルはGitHub Actionsワークフローファイル内の`uses:`フィールドで使用されているタグ参照(例: `@v4`)を、セキュリティのベストプラクティスに従ってSHA参照(例: `@11bd71901bbe5b1630ceea73d27597364c9af683 # v4.2.2`)に自動変換します。

## 使用タイミング

<trigger>

以下の場合にこのスキルを発動してください:

- ユーザーが「GitHub ActionsをSHA参照に変換して」と要求したとき
- ユーザーが「actionsのusesをSHAに書き換えて」と言及したとき

</trigger>

## 実行手順

<procedure>

### 1. 変更対象を確認

まず `--check --diff` オプションで、どのファイルが変更されるかを確認します:

```bash
pinact run --check --diff
```

**出力例**:

```
ERROR action isn't pinned
.github/workflows/ci.yaml:10
-       uses: actions/checkout@v4
+       uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
ERROR action isn't pinned
.github/workflows/ci.yaml:11
-     - uses: actions/setup-go@v4
+     - uses: actions/setup-go@4d34df0c2316fe8122ab82dc22947d607c0c91f9 # v4.0.0
ERROR action isn't pinned
.github/workflows/deploy.yaml:15
-       uses: actions/checkout@v4
+       uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
```

### 2. 変換を実行

確認後、`pinact run` を実行してすべての対象ファイルを一括変換します:

```bash
pinact run
```

pinactは以下を自動的に行います:
- タグ参照からコミットSHAを取得
- 最も詳細なバージョンタグ(v4.3.0など)をコメントとして追加
- `.github/workflows/*.{yml,yaml}` と `action.{yml,yaml}` を自動検出して変換

</procedure>

## 実装例

<examples>

### 例1: 基本的な使用方法

<example>

**ステップ1: 変更対象を確認**:

```bash
pinact run --check --diff
```

**出力**:

```
ERROR action isn't pinned
.github/workflows/ci.yaml:10
-       uses: actions/checkout@v4
+       uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
ERROR action isn't pinned
.github/workflows/ci.yaml:11
-     - uses: actions/setup-go@v4
+     - uses: actions/setup-go@4d34df0c2316fe8122ab82dc22947d607c0c91f9 # v4.0.0
```

**ステップ2: 変換を実行**:

```bash
pinact run
```

**変換後のワークフローファイル (.github/workflows/ci.yaml)**:

```yaml
name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
      - uses: actions/setup-go@4d34df0c2316fe8122ab82dc22947d607c0c91f9 # v4.0.0
```

</example>

</examples>

## 重要な注意事項

<important>

### すべきこと

- **pinactを使用**: GitHub Actions SHA参照変換には専用ツールpinactを使用する
- **まず --check --diff で確認**: `pinact run --check --diff` で変更対象を確認する
