Security: API Key Handling

CRITICAL: Read comprehensive security rules:

@docs/security/SECURITY-RULES.md

Never hardcode API keys, passwords, or secrets in any generated files.

When generating configuration or code:

• ❌ NEVER use real API keys or credentials
• ✅ ALWAYS use placeholders: your_service_key_here
• ✅ Format: {project}_{env}_your_key_here for multi-environment
• ✅ Read from environment variables in code
• ✅ Add .env* to .gitignore (except .env.example)
• ✅ Document how to obtain real keys

Security Requirements

CRITICAL: All generated files must follow security rules:

@docs/security/SECURITY-RULES.md

Key requirements:

• Never hardcode API keys, secrets, or tokens
• Use placeholders: your_github_token_here
• Protect .env files with .gitignore
• Create .env.example with placeholders only
• Document how to obtain GitHub tokens and NPM tokens

Input Parameters

You will receive:

• project_path: Root directory of the TypeScript/JavaScript project
• release_branches: Branches to release from (default: ["main", "master"])
• github_actions: Boolean - setup GitHub Actions workflow (default: true)
• npm_publish: Boolean - publish to NPM registry (default: false)

Task: Setup TypeScript Versioning

Step 1: Validate Project Structure

Check for TypeScript/JavaScript project markers:

• package.json exists and is valid JSON
• Contains name and version fields
• TypeScript project: tsconfig.json exists
• JavaScript project: No TypeScript config

Read package.json to get current version or default to "0.0.0"

Verify git repository:

• .git directory exists
• Working directory is clean or changes are stashed
• Current branch identified

Step 2: Install Dependencies

Add semantic-release and plugins to package.json:

{
  "devDependencies": {
    "semantic-release": "^23.0.0",
    "@semantic-release/changelog": "^6.0.3",
    "@semantic-release/git": "^10.0.1",
    "@semantic-release/github": "^9.2.0",
    "@semantic-release/npm": "^11.0.2"
  }
}

If npm_publish is false, omit @semantic-release/npm

Display: "Installing semantic-release dependencies..."

Execute: npm install --save-dev semantic-release @semantic-release/changelog @semantic-release/git @semantic-release/github

Step 3: Create Configuration Files

Create .releaserc.json with semantic-release configuration:

{
  "branches": ["main", "master"],
  "plugins": [
    "@semantic-release/commit-analyzer",
    "@semantic-release/release-notes-generator",
    "@semantic-release/changelog",
    "@semantic-release/npm",
    [
      "@semantic-release/git",
      {
        "assets": ["package.json", "package-lock.json", "CHANGELOG.md"],
        "message": "chore(release): ${nextRelease.version} [skip ci]\n\n${nextRelease.notes}"
      }
    ],
    "@semantic-release/github"
  ]
}

Customize based on parameters:

• branches: Use release_branches from input
• Remove @semantic-release/npm plugin if npm_publish is false

Create CHANGELOG.md if it doesn't exist:

# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

Step 4: Update package.json Scripts

Add release scripts to package.json:

{
  "scripts": {
    "release": "semantic-release",
    "release:dry-run": "semantic-release --dry-run"
  }
}

Preserve existing scripts, only add if not present

Step 5: Setup GitHub Actions (if enabled)

If github_actions is true, create .github/workflows/release.yml with:

• Trigger on push to main/master branches
• Setup Node.js with npm cache
• Run npm ci and npm run build
• Execute npx semantic-release with GITHUB_TOKEN
• Add NPM_TOKEN only if npm_publish is true

Security: Use GitHub Secrets, never hardcode tokens

Step 6: Create Documentation

Create docs/VERSIONING.md with:

• Conventional Commits specification (feat, fix, BREAKING CHANGE)
• Automated release process via GitHub Actions
• Manual commands: npm run release:dry-run and npm run release
• Setup requirements for GitHub/NPM tokens

Step 7: Configure .gitignore

Ensure .gitignore contains:

# Versioning
.semantic-release

Don't duplicate entries, only add if missing

Step 8: Verify Configuration

Run validation checks:

1. package.json has correct version format
2. .releaserc.json is valid JSON
3. Required dependencies installed
4. Git repository is clean
5. GitHub Actions workflow is valid YAML (if created)

Display validation results with checkmarks:

• ✅ package.json configured
• ✅ semantic-release installed
• ✅ Configuration files created
• ✅ GitHub Actions workflow ready (if enabled)

Output Format

Return structured results:

{
  "status": "success|error",
  "project_type": "typescript|javascript",
  "current_version": "0.0.0",
  "files_created": [
    ".releaserc.json",
    "CHANGELOG.md",
    ".github/workflows/release.yml",
    "docs/VERSIONING.md"
  ],
  "files_modified": [
    "package.json",
    ".gitignore"
  ],
  "dependencies_added": [
    "semantic-release",
    "@semantic-release/changelog",
    "@semantic-release/git",
    "@semantic-release/github"
  ],
  "next_steps": [
    "Commit changes with conventional format",
    "Push to main branch to trigger release",
    "Configure GitHub repository secrets if publishing to NPM"
  ],
  "error": "error message if status is error"
}

Error Handling

Handle failures gracefully:

• No package.json → Error: "Not a Node.js project"
• Invalid JSON → Error: "Corrupted package.json"
• Not a git repo → Error: "Git repository required"
• Dirty working tree → Warning: "Uncommitted changes present"
• Network failure during install → Error: "Failed to install dependencies"

Return clear error messages with remediation steps.
