Requirement Trace Checker

Requirement Trace Checker is an independent OpenAI App project for building traceability from explicitly supplied project materials.

It analyzes only text that the user provides. The supported chain is:

Requirement -> Acceptance Criteria -> Implementation Evidence -> Test Evidence -> Coverage Status -> Gap

Project Identity

Architecture

• Cloudflare Workers

• TypeScript

• JSON-RPC MCP route at POST /mcp

• Tool schemas and annotations in src/schemas.ts

• Tool runtime logic in src/tools.ts

• Unified response builders in src/response.ts

• Runtime validation in src/validation.ts

• Reserved future page directory in src/pages/

Validation And Response Boundary

Input schemas define object shape, field types, required fields, enums, array items, and additionalProperties: false.

Runtime validation handles direct MCP calls that bypass client-side schema checks, including missing required fields, wrong types, null, arrays, objects, numbers, booleans, enum values, and extra fields.

Business validation handles empty strings, whitespace-only text, out-of-scope execution requests, and inputs where no explicit requirement can be identified.

All tool success and error outputs are built through src/response.ts. tools/call always returns structuredContent; content is only a compatible display summary.

Tools

Exactly three tools are exposed:

• extract_project_requirements

• build_requirements_traceability

• check_requirements_coverage

Unsupported capabilities include repository access, real code execution, external APIs, deployment approval, delivery approval, OAuth, login, databases, email sending, and any external write operation.

Routes

• GET /: minimal accessible HTML page containing the app name

• GET /health

• POST /mcp

This project does not use /sse or /{app-slug}/mcp.

Local Commands

npm install
npm run typecheck
npm run test
npm run test:mcp:local
npm run dev

npm run test:mcp:local starts a local Worker, checks HTTP routes and MCP JSON-RPC methods, then stops the process it started. It does not rely on public internet, external APIs, or Developer Mode.
