+# codebase-auditor
+
+Multi-dimensional codebase quality assessment agent that orchestrates specialized reviewers in parallel — code quality, security vulnerabilities, secret detection, architecture integrity, and dependency health — and synthesizes findings into a single deduplicated, severity-ranked report with a binary PASS/FAIL verdict.
+
+## Run
+
+```bash
+npx @open-gitagent/gitagent run -r https://github.com/Mathews-Tom/codebase-auditor
+```
+
+## What It Can Do
+
+- **Scope Analysis** — determines audit scope from changed files, direct dependencies, or full repository inventory
+- **Parallel Agent Spawning** — runs code quality, security, and secret detection reviews concurrently
+- **Architecture Review** — assesses structural integrity, module boundaries, coupling, and scalability patterns
+- **Dependency Audit** — checks for CVEs, license compliance, abandoned packages, and dependency bloat
+- **Aggregation and Deduplication** — merges overlapping findings, preserves highest severity, eliminates report noise
+- **Verdict Determination** — binary PASS (zero CRITICAL/HIGH) or FAIL with prioritized action items
