Change-impact analysis for engineers and coding agents

A local-first developer tool that traces the blast radius of a Git change, recommends relevant tests, and gives coding agents structured context before they edit or merge.

Blast-radius tracing

Reverse-dependency paths connect each changed file to the code it can affect, then turn that evidence into focused verification guidance.

Agent-ready context

Typed, read-only MCP tools let coding agents forecast proposed edits or inspect a real worktree without receiving broad filesystem access.

Deterministic first

Risk, test recommendations, and CI exit status come from local analysis; an optional model can explain evidence but cannot change it.

• Authored 116 pull requests to AWS Kiro Crew: 71 merged, 12 open, and 33 closed without merge; GitHub credits 71 commits to the repository's contributor graph.
• Shipped a scheduler re-arm fix that removed cron runs starting up to 30 seconds late and a race-condition fix that stopped stale message caching during concurrent rewrites.
• Stabilized CI and hardened the runtime — replaced wall-clock timing in flaky async tests with event-based waits, fixed a Windows file-handling bug, attached an AppArmor security profile to the systemd service, and aligned UI copy across all 11 translated locales the product supports.
