Display directory structure as a formatted tree. Use when the user needs to visualize a directory structure, analyze folder organization, or share a file tree view. Supports custom paths via the /tree command.
Automatically capture Bash commands executed by Claude Code and convert them into documented, organized Makefile targets in .claude/makefiles/. Use when Claude executes any Bash command, when tempted to skip documentation ("too trivial", "one-time", "will do later"), or when user asks for Makefile generation. Process commands NOW while fresh, not later.
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for OpenCode.
Build production-grade CLI tools with Bun. Reference implementation covering argument parsing patterns (--flag value, --flag=value, --flag), dual markdown/JSON output, error handling, subcommands, and testing. Use when building CLIs, designing argument parsing, implementing command structures, reviewing CLI quality, or learning Bun CLI best practices.
This skill should be used when performing exploratory testing of command-line tools and scripts, including help text validation, option testing, error handling verification, and output validation. Triggers when testing CLI commands, scripts, build tools, or command-line interfaces.
Design command-line interface parameters and UX: arguments, flags, subcommands, help text, output formats, error messages, exit codes, prompts, config/env precedence, and safe/dry-run behavior. Use when you're designing a CLI spec (before implementation) or refactoring an existing CLI's surface area for consistency, composability, and discoverability.
Create organized bash script structure with color output, menu systems, error handling, and cross-platform support. Standardizes CLI tooling.
Fork terminal sessions to spawn parallel AI agents or CLI commands in new terminal windows. Supports git worktrees for isolated parallel development.
Use when you need to open a production console or inspect production logs via Kamal for this Micelio app.
This skill should be used when commands need to determine which spec is active, when the user mentions "spec 001", "work on feature X", or when checking current spec context. Resolves the current working specification through user input, progress.yml, or user selection.
This skill should be used when the user asks to "set up shell completions", "fix zsh completions", "configure tab completion", "add completions for brew/npm/cargo", "troubleshoot missing completions", or mentions fpath, compinit, or Oh My Zsh completion issues.
Use when creating, editing, or reviewing custom OpenCode commands. Covers frontmatter options, prompt templating with arguments and shell output, file references, and agent/model configuration.
Build multi-level interactive CLI menus for bash scripts
Expert guidance for Rust CLI and TUI development with official examples from clap, inquire, and ratatui libraries. Use when building command-line interfaces, terminal user interfaces, or console applications in Rust. Provides structured patterns, best practices, and real code implementations from official sources.
Spawn a new terminal window to run CLI commands (ffmpeg, curl, python, etc.). Use for non-AI command execution.
Fork a terminal session to a new terminal window. Use this when the user requests 'fork terminal' or 'create a new terminal' or 'new terminal: <command>' or 'fork session: <command>'.
