Description
CodeReview GPT is a GitHub App that automatically reviews pull requests. It parses diffs into semantically meaningful hunks, enriches them with surrounding file context, and asks an LLM to produce inline review comments.
Beyond style feedback, it runs a dedicated security pass (injection, secrets, authz gaps) and assigns each PR a risk score displayed as a status check.
- Processed 2,000+ pull requests across pilot repositories with a 92% comment-acceptance-or-acknowledge rate.
- Reduced average human review turnaround from 8 hours to under 2 by pre-triaging trivial changes.
- Built diff-aware context packing that cut token usage ~40% versus naive full-file prompts.
- Shipped as a Dockerized GitHub App with per-org config for tone, strictness, and ignored paths.
