elements-of-style
Applies the classic writing rules from Strunk's style guide to any prose people will read, such as documentation, commit messages, error messages and reports, so the text comes out clearer and more concise.

superpowers-lab
Finds functions that do the same job under different names, queries MCP servers only when you ask so they stay out of your context, drives interactive tools like vim or a Python REPL through tmux, and sets up a headless Windows VM you can SSH into.

/finding-duplicate-functionsUse when auditing a codebase for semantic duplication - functions that do the same thing but have different names or implementations. Especially useful for LLM-generated codebases where new functions are often created rather than reusing existing ones./mcp-cliUse MCP servers on-demand via the mcp CLI tool - discover tools, resources, and prompts without polluting context with pre-loaded MCP integrations/using-tmux-for-interactive-commandsUse when you need to run interactive CLI tools (vim, git rebase -i, Python REPL, etc.) that require real-time input/output - provides tmux-based approach for controlling interactive sessions through detached sessions and send-keys/windows-vmCreate, manage, or connect to a headless Windows 11 VM running in Docker with SSH access. Use when the user wants to spin up, stop, restart, or SSH into a Windows VM.
README
Superpowers Lab
Experimental skills for Claude Code Superpowers - new techniques and tools under active development.
What is this?
This plugin contains experimental skills that extend Claude Code's capabilities with new techniques that are still being refined and tested. These skills are functional but may evolve based on real-world usage and feedback.
Current Skills
finding-duplicate-functions
Detect semantic code duplication in LLM-generated codebases. Unlike traditional copy-paste detectors that find syntactic duplicates, this skill identifies functions with the same intent but different implementations.
Use cases:
- Audit codebases that have grown organically with multiple contributors
- Identify utility functions that have been reimplemented multiple times
- Find consolidation opportunities before major refactoring
- Complement jscpd after syntactic duplicates are handled
How it works: Two-phase approach using classical function extraction followed by LLM-powered intent clustering. Haiku categorizes functions by domain, then Opus analyzes each category to find semantic duplicates.
See skills/finding-duplicate-functions/SKILL.md for full documentation.
mcp-cli
Use MCP servers on-demand via the mcp CLI tool. Discover and invoke tools, resources, and prompts without polluting context with pre-loaded MCP integrations.
Use cases:
- Query MCP servers without permanent configuration
- Explore available tools before deciding to integrate
- One-off MCP tool invocations
See skills/mcp-cli/SKILL.md for full documentation.
using-tmux-for-interactive-commands
Enables Claude Code to control interactive CLI tools (vim, git rebase -i, menuconfig, REPLs, etc.) through tmux sessions.
Use cases:
- Interactive text editors (vim, nano)
- Terminal UI tools (menuconfig, htop)
- Interactive REPLs (Python, Node, etc.)
- Interactive git operations (rebase -i, add -p)
- Any tool requiring keyboard navigation and real-time interaction
How it works: Creates detached tmux sessions, sends keystrokes programmatically, and captures terminal output to enable automation of traditionally manual workflows.
See skills/using-tmux-for-interactive-commands/SKILL.md for full documentation.
windows-vm
Create, manage, or connect to a headless Windows 11 VM running in Docker with KVM acceleration and SSH access — no RDP or GUI required.
Use cases:
- Spin up a Windows environment for testing or development
- Run Claude Code on Windows via SSH
- Test cross-platform behavior without leaving the terminal
How it works: Uses dockur/windows to run Windows 11 in a Docker container with KVM acceleration. Manages the full lifecycle: create, start, stop, restart, SSH, and status checks. Includes automated setup of OpenSSH Server, Node.js, and Claude Code inside the VM.
See skills/windows-vm/SKILL.md for full documentation.

Semantic search over past Claude Code conversations, so a session can recall earlier discussions, decisions, and patterns. It adds a remembering-conversations skill that checks prior sessions before the assistant says it doesn't know.

@confident-aiQuestions about superpowers-lab.
Finds functions that do the same job under different names, queries MCP servers only when you ask so they stay out of your context, drives interactive tools like vim or a Python REPL through tmux, and sets up a headless Windows VM you can SSH into. Install it with the command on its page. It includes finding-duplicate-functions, mcp-cli, using-tmux-for-interactive-commands. Its skills do not fire on their own yet. Free and open source.

- How do I install superpowers-lab?
- Run these in Claude Code: npx -y skills add obra/superpowers-lab --agent claude-code. Then prompt normally.
- Does superpowers-lab auto-invoke its skills?
- Not yet. It is indexed on Flowy as a plain plugin.
- Is superpowers-lab free?
- Yes. Flowy is free and open source, with nothing gated. You can read every skill in full before you install.
- Which coding agents can use superpowers-lab's skills?
- superpowers-lab installs in Claude Code, and its skills also install in Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI. Each skill's page has the install command. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
