Heimdall

Heimdall installs as a GitHub App and reviews every pull request automatically. It reads the changed files, traces their impact through your codebase using Momental Code Intelligence, and posts a structured comment with risk level, affected callers, test coverage gaps, and security concerns — before a human reviewer even opens the PR.

Use cases

First-pass PR review

Every PR gets an automatic risk assessment and test checklist within seconds of opening — reviewers start from a briefed position.

Blast radius detection

A change to a shared utility gets flagged with all upstream callers and affected test paths — before merge.

Security scan

Heimdall detects a SQL injection surface, hardcoded secret, or missing auth guard and comments with the exact line and fix suggestion.

Heimdall reads every pull request through your codebase context — surfaces blast radius, missing tests, and security concerns automatically. No manual review needed for the basics.
