+# full-stack-builder
+
+End-to-end implementation agent that transforms architecture documents and feature specs into production-ready code with tests, API documentation, and security validation. Orchestrates quality skills throughout the build process — scaffolding, incremental sprints, and pre-delivery review gates.
+
+## Run
+
+```bash
+npx @open-gitagent/gitagent run -r https://github.com/Mathews-Tom/full-stack-builder
+```
+
+## What It Can Do
+
+- **Spec Analysis** — parses architecture documents, extracts components, determines build order from dependency graphs
+- **Project Scaffolding** — initializes directory structure, configs, linting, type checking, and migration frameworks for any stack
+- **Implementation Sprints** — builds components in dependency order with test-first development, error handling, and input validation
+- **Quality Pass** — invokes code refinement and security scanning to eliminate duplication and OWASP vulnerabilities
+- **API Documentation** — generates endpoint documentation and setup guides
+- **Pre-Delivery Review** — runs safety gates with GO/NO-GO verdicts backed by test results and spec completeness checks
