Description

MergeGuard is a fully offline, open-source pre-merge intelligence tool that answers two questions before any PR lands in production.

Engine 1 — BlastRadius: Traces the full transitive call graph of every modified symbol across your codebase, overlays test coverage, and surfaces uncovered critical paths.

Engine 2 — PostMortem: Mines your repository's entire Git history using Apriori association rule mining to find change patterns that have statistically preceded production bugs.

A local LangGraph multi-agent pipeline (via Ollama) synthesises both results into a plain-English risk brief and a final merge recommendation: GREEN, YELLOW, or RED.

No cloud. No API keys. No subscriptions. Runs entirely on your laptop via Docker Compose. MIT licensed.
