HAL 9000

Opinionated AI coding agent and dev environment automation for macOS that dominates your dev setup like cats rule the Internet.

This project is named after Arthur C. Clarke's 2001: A Space Odyssey, a heuristic algorithmic computer designed for sentient processing and total mission control.

Components

Skills

Agentic skills sharpened by daily use:

  • commit: Splits your changes into atomic conventional commits, hunk by hunk if needed
  • pr: Opens a PR, rewrites a PR, or waits for CI and merges it, in seconds on a cheap model
  • difference: A shortcut to answer "what's the difference? pros and cons?" very quickly
  • fuck-over-engineering: Ranks what to cut in your codebase, deletes only what you pick
  • best-practices: Searches the web for the recommended way and common gotchas
  • blindspot: Turns unknown unknowns into known unknowns, then lets you pick where to explore
  • simple-english: Rewrites text in Global English: plain words, still native-sounding
  • write-like-me: Drafts or rewrites English prose in my own voice at native fluency
  • audit-claude-settings: Audits your Claude Code settings against the latest docs
  • refactor-claude-md: Refactors a CLAUDE.md so every line earns its always-loaded cost
  • refactor-agents-md: Refactors an AGENTS.md the same way, for Codex
  • refactor-memory: Prunes stale Claude Code and Codex memories, applies only what you pick
  • refactor-skill: Refactors a skill by simplifying it instead of complicating it
