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:

{
  text: string;
  rules: Array<{
    find?: string;
    replace?: string;
    pattern?: string;
    replacement?: string;
  }>;
}

Output:

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

Example Usage:

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, ... }, ...]

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:

{
  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:

{
  snippet: string;
  language: string;
  imports: string[];
}

Example Usage:

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:

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()

cURL Example:

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" }'

• 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

• 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
