Change-impact analysis for engineers and coding agents

A local-first change-impact analyzer that traces Git changes through Python, TypeScript aliases, and workspace packages, then recommends tests and review context for coding agents.

CLI, Action, MCP
3 surfaces
deterministic core
Local-first
v0.5.1 release gate
226 tests

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.

Monorepo-aware analysis

Resolves TypeScript aliases and npm/Yarn workspace exports, while retaining dependency evidence for deleted and renamed source files.

What Is This? Guide

Available on the Chrome Web Store

MV3

A private Chrome side-panel guide that explains the visible part of the current tab using Chrome's built-in, on-device AI.

  • Captures only the visible tab after an explicit request.
  • Supports identify, explain, troubleshoot, compare, and step-by-step guidance.
  • Keeps screenshots and context on-device with no account, analytics, or tracking.

Token Optimizer

Available on the Chrome Web Store

MV3

A Chrome side-panel workflow that cleans up rough prompts before inserting the reviewed result into Gemini or ChatGPT.

  • Captures or accepts pasted prompt text only after explicit consent.
  • Uses deterministic preparation without making another provider-model call.
  • Never auto-sends: the user reviews and inserts the prepared prompt manually.

  • Authored 124 pull requests to AWS Kiro Crew: 80 merged, 2 open, and 42 closed without merge; GitHub credits 80 commits to the repository's contributor graph.
  • Prevented silently truncated speech transcripts across the dashboard, Slack, and shared messaging channels by checking provider limits and refusing recordings whose duration could not be verified.
  • 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.
