Create a new custom slash command following conventions and best practices

Parallelize work across agent teams using git worktrees and tmux

Manage Git worktrees for parallel development sessions

Scan a codebase to extract high-confidence coding conventions as ranked evidence. This agent SHOULD be used when analyzing a project's established patterns before planning or implementation.

Apply Go best practices, idioms, and conventions from golang.org/doc/effective_go. This skill SHOULD be used when writing, reviewing, or refactoring Go code to ensure idiomatic, clean, and efficient implementations.

This skill SHOULD be used when writing, reviewing, or refactoring Neovim plugins in Lua. Apply Neovim community best practices, plugin architecture patterns, and idiomatic Lua style to ensure clean, maintainable plugins.

Invoke external AI CLIs (Codex, Gemini) for second opinions, code reviews, or alternative analysis. This skill SHOULD be used when the user asks for a "second opinion", "outside review", says "ask codex", "ask gemini", "run codex", "run gemini", "get another AI's take", or needs verification from a different model.

This skill SHOULD be used when the user asks to "build an AI assistant", "create a chatbot", "make an agent that does X for me", "design a copilot feature", "automate this workflow with AI", or requests delegation-style AI features. Offers a reframe from copilot patterns (conversation, delegation) to HUD patterns (ambient awareness, perception augmentation).

This skill SHOULD be used when the user asks to "get the version from package.json", "extract field from JSON", "get a field from docker-compose", "extract value from yaml", "get code blocks from README", "extract links from markdown", "find all headers in this doc", "search for pattern in codebase", "find all uses of function", "grep for string across files", "find TODO comments", "search in specific file types", "count occurrences", or when needing specific fields from JSON, YAML, or Markdown files without loading the entire file, or when needing efficient text search with context, line numbers, or special flags beyond the built-in Grep tool.

Audit and improve CLAUDE.md files in repositories. This skill SHOULD be used when the user asks to check, audit, update, improve, or fix CLAUDE.md files. Scans for all CLAUDE.md files, evaluates quality against templates, outputs quality report, then makes targeted updates. This skill SHOULD also be used when the user mentions "CLAUDE.md maintenance" or "project memory optimization".

Create distinctive, production-grade frontend interfaces with high design quality. This skill SHOULD be used when the user asks to build web components, pages, artifacts, posters, or applications (examples: websites, landing pages, dashboards, React components, Astro components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

Generate and edit images using the Gemini API (Nano Banana). This skill SHOULD be used when creating images from text prompts, editing existing images, applying style transfers, generating logos with text, creating stickers, product mockups, or any image generation/manipulation task. Supports text-to-image, image editing, multi-turn refinement, and composition from multiple reference images.

Structured reasoning through competing hypotheses using the ADI cycle (Abduction, Deduction, Induction). This skill SHOULD be used when the user says "reason through", "compare approaches", "evaluate options", "which approach", "what's the best way to", "I have multiple options", "help me decide between", "structured analysis", "hypothesis", "trade-off analysis", "hypothesize", "sc-hypothesize", or faces a decision with multiple viable approaches that need systematic evaluation. NOT for quick decisions with obvious answers — use sc-socratic for open-ended dialogue instead.

Generate mermaid diagrams — flowcharts for architecture, sequence diagrams for interactions. This skill SHOULD be used when the user asks to "create a diagram", "draw an architecture diagram", "sequence diagram", "flowchart", "visualize the system", or "generate mermaid".

Detect codebase conventions and generate pattern briefs for AI-guided planning. This skill SHOULD be used when the user asks to "analyze patterns", "detect conventions", "what patterns does this codebase use", "pattern brief", "initialize pattern detection", or before major planning/implementation work.

Socratic thinking partner for decisions, debugging mental models, and working through uncertainty. This skill SHOULD be used when the user says "I'm stuck", "should I", "can't decide", "not sure if", "is this the right approach", "what do you think about", "help me think through", "review my plan", "am I missing something", "what am I assuming", "let me think", "brainstorm", "help me figure out", "sanity check", "does this make sense", "sc-socratic", or expresses uncertainty about a decision, design, or direction. Activates dialectical reasoning to surface assumptions, challenge positions, and find the right question to ask.

Reframe code design through functional programming principles for agent-assisted development. This skill SHOULD be used when the user says "think functional", "think FP", "make this pure", "separate effects", "where should this side effect go", "this function does too much", "how should I structure this for agents", "make this easier to review", "reduce context needed", or when planning module structure, store design, or code that agents will write and humans will review. Applies FP discipline within any language to maximize agent effectiveness and human reviewability.
