Building a Local AI Code Reviewer with Ollama That Catches Bugs Before Your Team

Short summary

Build a local TypeScript CLI that feeds staged git diffs to Ollama's qwen2.5-coder:7b model to catch logic errors, null-access bugs, security issues, and resource leaks before you commit. Wire it as a git pre-commit hook with Zod schema validation for structured JSON findings that classify each issue by severity. No API keys, no cloud, no code exposure—everything runs locally, giving you a second pair of eyes with zero vendor risk.

• •Local LLM code review eliminates API key and cloud exposure risk
• •Pre-commit hook integration blocks bad commits before team review
• •Zod schema validation ensures reliable, structured findings from model output
