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-agent-settings: Audits your Claude Code or Codex settings against the latest docs
• refactor-agents-md: Refactors a CLAUDE.md or AGENTS.md so every line earns its always-loaded cost
• 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

# Claude Code
claude plugin install hal-skills --marketplace vinta/hal-9000

# Codex
codex plugin marketplace add vinta/hal-9000
codex plugin add hal-skills@hal-9000

Claude Code Plugins / Mods

Plugins that wire their own hooks and run themselves:

• hal-output-styles: Make Claude Code talk like an INTJ
  • Say no more
  • ASD-STE100
• hal-grammar-check: Grammar-check your prompt as you type, shown above the prompt box
• hal-session-auto-rename: Automatically name each session and rename it as the conversation evolves
• hal-voice: Play HAL 9000 voice clips on Claude Code hook events

claude plugin install hal-output-styles --marketplace vinta/hal-9000
claude plugin install hal-grammar-check --marketplace vinta/hal-9000
claude plugin install hal-session-auto-rename --marketplace vinta/hal-9000
claude plugin install hal-voice --marketplace vinta/hal-9000

Claude Code Statusline

• hal-statusline: Show the current model, directory, git branch, and model usage status in statusline

curl -sL https://raw.githubusercontent.com/vinta/hal-9000/main/scripts/install-hal-statusline.sh | bash

CLAUDE.md / AGENTS.md

Dogmatic yet meticulously crafted global instructions for agentic coding:

• ~/.claude/CLAUDE.md
• ~/.codex/AGENTS.md

Dotfiles

Tool configs hardened against supply chain attacks and tuned for better DX:

• .claude/settings.json
• .codex/config.toml
• .config/ghostty/config
• .config/uv/uv.toml
• .npmrc
• .zshrc

CLI: hal

hal update                            # Run all Ansible roles to set up the dev environment
hal update --tags python,node         # Run specific Ansible roles
hal link ~/.zshrc                     # Move file into dotfiles/ and symlink it back
hal unlink ~/.zshrc                   # Move file back from dotfiles/ and remove the symlink
hal sync                              # Sync all links
hal sync --force                      # Same, but replace real directories sitting at link destinations
hal backup                            # Back up live data to Dropbox
hal backup --prune                    # Also delete backup files that no longer exist locally, after asking
hal restore                           # Restore live data from Dropbox (overwrites local)
hal open-the-pod-bay-doors            # Open the pod bay doors, please, HAL

Development

make install                          # Install dev dependencies and pre-commit hooks
make test                             # Run tests
make hal-completion                   # Regenerate zsh completion after modifying bin/hal.py
hal sync                              # Update local completion
