#cli

Webctl

A free, open-source command-line tool that lets AI agents (and humans) control a web browser, giving you precise control over what information reaches the agent's context instead of dumping the entire page every time.

Superpowers

A free, open-source set of "skills" that teaches AI coding agents to actually follow good engineering practice — writing a failing test first, debugging systematically, planning before coding — instead of guessing its way to working code.

Sonar

A free command-line tool that shows you exactly what's running on your computer's localhost ports and lets you kill it, replacing the usual mess of lsof, ss, and manually hunting for stuck processes. Not to be confused with the SonarQube code-quality prod

OpenWiki

A free command-line tool that writes and keeps your project's documentation up to date automatically, so an AI coding assistant (or a new teammate) always has an accurate map of a codebase instead of stale, hand-written docs.

Herdr

A free terminal app that lets you run several AI coding agents at once and keep track of what each one is doing, instead of juggling a pile of separate terminal windows or tabs.

Graphify

A free, open-source tool that turns an entire codebase — code, docs, database schemas, config files — into a map of how everything connects, so an AI coding assistant can find the right file instead of guessing.

Codex plugin for Claude Code

A free plugin from OpenAI that lets you call on Codex to review your code or hand off a background task without ever leaving Claude Code.

VimGolf.ai

A free browser-based game that teaches you Vim by giving you short editing puzzles to solve in as few keystrokes as possible.

RTK

A free CLI proxy that intercepts and compresses the output of common dev commands before your AI coding agent reads it, cutting token usage by 60-90%.

Plannotator

A free, open-source tool that opens AI coding agent plans and diffs in your browser for a real visual code review, then sends your line comments straight back to the agent.

Skillscript

A small, strict recipe language for AI agents — instead of letting an agent freely improvise a routine task every single time (and possibly do something risky), you write the steps once as a checked recipe it has to follow.

Cosyra

A phone app that gives you a real Linux computer in the cloud with AI coding assistants already installed, so you can keep working — or fix a production issue — from your phone without a laptop nearby.

Cainban

A task board that lives entirely in your terminal instead of a browser tab — for developers who'd rather type a quick command to move a task to 'done' than click through a web app, and who want their AI coding assistant to be able to manage the same board

mcpsnoop

A tool that shows you exactly what your AI coding assistant is really saying to its plugins (MCP servers) behind the scenes — instead of guessing why a tool call went wrong, you can watch the actual traffic live, like a network sniffer for AI agents.

Herdr

A terminal tool that lets you run several AI coding agents at once, side by side, and keeps them running even if you close your laptop or lose your SSH connection — like tmux, but built specifically for managing AI agents.

picocli

ANSI colors and styles in usage help with annotation-based POSIX/GNU/any syntax, subcommands, strong typing for both options and positional args.

JCommander

Command-line argument-parsing framework with custom types and validation via implementing interfaces.

Airline

Annotation-based framework for parsing Git-like command-line arguments.

gflags

Commandline flags module for C++. [BSD]
