Mikado Refactor Assistant

Summary

  • Provides a commit‑based DAG of incremental refactor tasks, automatically resets state between iterations, and visualizes dependencies.
  • Core value: confidence in small, safe refactor steps without messy state or lost context.

Details

Key Value
Target Audience Teams refactoring legacy codebases with Mikado‑style incremental changes
Core Feature Git‑hook driven DAG, state reset, AI‑generated plan, visual timeline
Tech Stack Node.js, TypeScript, Git hooks, D3.js, OpenAI API
Difficulty Medium
Monetization Revenue‑ready: $49/month per team

Notes

  • HN commenters say “the tricky part is that it is very tempting to not fully reset between mikado iterations” – this tool solves that.
  • Sparks discussion on AI‑assisted planning vs manual planning.

Legacy Test Generator

Summary

  • Analyzes a legacy codebase, infers behavior, and auto‑generates unit test skeletons with coverage hints.
  • Core value: turns “no tests” into a testable codebase, catching regressions early.

Details

Key Value
Target Audience Developers maintaining legacy systems with little or no test coverage
Core Feature Static analysis, dynamic instrumentation, AI‑driven test case generation, coverage reporting
Tech Stack Python, AST parsing, coverage.py, pytest, OpenAI API
Difficulty Medium
Monetization Hobby

Notes

  • Commenters lament “I’ve never worked on a project with any meaningful test coverage” – this tool directly addresses that pain.
  • Opens debate on the limits of AI‑generated tests and how to validate them.
