---

## 1. doc.styleRewrite

**Path:** `/packages/tools/official/style-rewrite/`

**Purpose:** Rewrites text to match a style guide using find/replace rules.

**Key Features:**
- Supports simple string replacement (find/replace)
- Supports regex patterns (pattern/replacement)
- Tracks all changes applied
- Returns before/after length statistics

**Input:**
```typescript
{
  text: string;
  rules: Array<{
    find?: string;
    replace?: string;
    pattern?: string;
    replacement?: string;
  }>;
}
```

**Output:**
```typescript
{
  rewritten: string;
  changesApplied: Array<{
    rule: string;
    matches: number;
    preview: string;
  }>;
  originalLength: number;
  newLength: number;
}
```

**Example Usage:**
```typescript
import { styleRewriteTool } from '@tpmjs/tools-style-rewrite';

const result = await styleRewriteTool.execute({
  text: "The colour is grey. Programme the API.",
  rules: [
    { find: "colour", replace: "color" },
    { find: "grey", replace: "gray" },
    { find: "Programme", replace: "Program" }
  ]
});
// result.rewritten: "The color is gray. Program the API."
// result.changesApplied: [{ rule: "Find: colour → Replace: color", matches: 1, ... }, ...]
```

## 2. doc.meetingMinutesFormat

**Path:** `/packages/tools/official/meeting-minutes-format/`

**Purpose:** Formats meeting minutes from structured input into professional markdown.

**Key Features:**
- Professional markdown formatting
- Automatic action item extraction
- Attendee tracking
- Numbered discussion sections

**Input:**
```typescript

  title: string;
  date: string;
  attendees: string[];
  items: Array<{
    topic: string;
    discussion: string;
    action?: string;
  }>;
}
```

**Output:**
```typescript
{
  minutes: string;        // Formatted markdown
  actionItems: Array<{
    topic: string;
    action: string;
  }>;
  attendeeCount: number;
}
```

**Example Usage:**
```typescript
import { meetingMinutesFormatTool } from '@tpmjs/tools-meeting-minutes-format';

## 3. doc.testPlanMatrix

**Path:** `/packages/tools/official/test-plan-matrix/`

**Purpose:** Creates a test coverage matrix showing which features are covered by which test types.

**Key Features:**
- Visual test coverage matrix
- Coverage percentage calculation
- Gap identification (missing test types)
- Validates coverage mappings

**Input:**
```typescript
{
  features: string[];
  testTypes: string[];

  matrix: Array<Array<{
    feature: string;
    testType: string;
    covered: boolean;
  }>>;
  coverage: Array<{
    feature: string;
    coveredTypes: string[];
    coveragePercentage: number;
  }>;
  gaps: Array<{
    feature: string;
    missingTestTypes: string[];
  }>;
}
```

**Example Usage:**
```typescript
import { testPlanMatrixTool } from '@tpmjs/tools-test-plan-matrix';

const result = await testPlanMatrixTool.execute({
  features: ["Login", "Checkout", "Search"],
  testTypes: ["unit", "integration", "e2e"],
  coverage: {
    "Login": ["unit", "e2e"],
    "Checkout": ["integration", "e2e"],
    "Search": ["unit"]
  }
});
// result.coverage[0]: { feature: "Login", coveredTypes: ["unit", "e2e"], coveragePercentage: 67 }
// result.gaps[0]: { feature: "Login", missingTestTypes: ["integration"] }
```

## 4. eng.openapiSnippetBuild

**Path:** `/packages/tools/official/openapi-snippet-build/`

**Purpose:** Generates code snippets from OpenAPI operation definitions.

**Key Features:**
- Supports JavaScript, TypeScript, Python, cURL, and Go
- Handles path/query/header parameters
- Request body support
- Automatic import detection

**Input:**
```typescript
{
  operation: {
    method: string;
    path: string;
    parameters?: Array<{
      name: string;
      in: 'path' | 'query' | 'header' | 'body';
      required?: boolean;
      type?: string;
      example?: any;
    }>;
    requestBody?: {
      required?: boolean;
      content?: Record<string, { example?: any }>;
    };
  };
  language: 'javascript' | 'typescript' | 'python' | 'curl' | 'go';
}
```

**Output:**
```typescript
{
  snippet: string;
  language: string;
  imports: string[];
}
```

```typescript
import { openapiSnippetBuildTool } from '@tpmjs/tools-openapi-snippet-build';

const result = await openapiSnippetBuildTool.execute({
  operation: {
    method: "POST",
    path: "/api/users/{id}",
    parameters: [
      { name: "id", in: "path", example: "123" },
      { name: "Authorization", in: "header", example: "Bearer token" }
    ],
    requestBody: {
      content: {
        "application/json": {
          example: { name: "John Doe", email: "john@example.com" }
        }
      }
    }
  },
  language: "javascript"
});
// result.snippet: "const response = await fetch('https://api.example.com/api/users/123', {\n  method: 'POST',\n  ..."
```

**Python Example:**
```python
response = requests.post(
    'https://api.example.com/api/users/123',
    headers={"Authorization":"Bearer token"},
    json={
      "name": "John Doe",
      "email": "john@example.com"
    }
)

data = response.json()
```

```bash
curl -X POST 'https://api.example.com/api/users/123' \
  -H 'Authorization: Bearer token' \
  -H 'Content-Type: application/json' \
  -d '{ "name": "John Doe", "email": "john@example.com" }'
```

## Package Metadata

Each tool includes proper `tpmjs` metadata in `package.json`:

- **Category:** `documentation` (tools 1-3), `engineering` (tool 4)
- **Frameworks:** `vercel-ai`
- **Keywords:** Appropriate tags for discoverability
- **Repository:** Links to GitHub repository
- **License:** MIT

---

## Dependencies

All tools use minimal dependencies:
- **ai:** `6.0.0-beta.124` (AI SDK v6)
- **No external runtime dependencies** (except AI SDK)
- Dev dependencies: `@tpmjs/tsconfig`, `tsup`, `typescript`

---

## File Structure

Each tool follows the standard structure:

```
tool-name/
├── src/
│   └── index.ts          # Main implementation
├── dist/                 # Build output (generated)
│   ├── index.js         # ESM JavaScript
│   └── index.d.ts       # TypeScript definitions
├── package.json         # Package metadata with tpmjs config
├── tsconfig.json        # TypeScript configuration
└── tsup.config.ts       # Build configuration
```

---

## Next Steps

The tools are ready for use. To add them to the blocks registry:

1. Update `blocks.yml` to include the new tools (as requested, this was NOT done automatically)
2. Publish to npm via changesets workflow
3. Update documentation/website to showcase the new tools

## Implementation Notes

**Code Quality:**
- All code includes comprehensive JSDoc comments
- Full TypeScript type safety
- Error handling with descriptive messages
- Input validation for all parameters
- Follows existing codebase patterns

**Testing:**
- Type-checked with strict TypeScript settings
- Builds successfully with tsup
- No external dependencies to manage
- Self-contained implementations

**AI SDK Integration:**
- Uses `tool()` from AI SDK v6
- Uses `jsonSchema()` for input validation
- Proper async/await patterns
- Returns strongly-typed results
