CLI Tools

File system operations with babashka.fs. Use when working with file I/O, directory traversal, path manipulation, file copying/moving, temp files, archives (zip/gzip), or file metadata.

Builds and manages iOS/macOS apps using xcodebuild and xcrun simctl CLI tools. Use when working with Xcode projects, running apps in simulators, managing simulator instances, taking screenshots, capturing logs, running tests, or automating builds.

Guide for creating Claude Code hooks - user-defined shell commands that execute at lifecycle points. Use when the user wants to create, add, or configure a hook for Claude Code, including PreToolUse, PostToolUse, Notification, UserPromptSubmit, Stop, SubagentStop, PreCompact, SessionStart, or SessionEnd hooks.

Use this skill when the user wants to create, write, or install shell scripts. Prefers Fish shell, handles writing fish/bash/zsh/sh scripts and installing them to ~/bin/scripts with proper permissions and git workflow. Activates when user mentions "shell script", "bash script", "fish script", "install script", or wants to create command-line utilities.

Build the Gambit game engine (Server and Client executables). Use when the user wants to compile the project, needs to rebuild after code changes, or before running the server or client.

Automatically manage Python virtual environments (.venv) in terminal commands. Always activate .venv before running Python/pip commands. Use when executing Python scripts, installing packages, or running development servers. Critical for consistent environment management.

WHEN: Next.js project review, App Router patterns, Server/Client Component separation, data fetchingWHAT: Router pattern analysis + SC/CC separation + next/image·font optimization + Server Actions reviewWHEN NOT: General code quality → code-reviewer, Bundle performance → perf-analyzer

LLM invocation patterns from hooks via SDK. Use when you need background agents, CLI calls, or cost optimization.

Deploy and manage Docker containers on Cloudflare's global network alongside Workers. Use when building applications that need to run Python code, process large files (multi-GB zips, video transcoding), execute CLI tools, run AI inference, create code sandboxes, or any workload requiring more memory/CPU than Workers provide. Triggers include requests to run containers, execute arbitrary code, process large files, deploy backend services in Python/Go/Rust, or integrate heavyweight compute with Workers.

Use this skill when creating new Claude Code skills from scratch, editing existing skills to improve their descriptions or structure, or converting Claude Code sub-agents to skills. This includes designing skill workflows, writing SKILL.md files, organizing supporting files with intention-revealing names, and leveraging CLI tools and Node.js scripting.

Splynx REST API client for validated operations on ISP management data.Use when creating, updating, or deleting customers, services, tariffs, invoices, documents, or tickets in Splynx.Validates data before writing. Reference: src/apis/splynx_client.py

Guide for choosing between Server Components and Client Components in Next.js App Router. CRITICAL for useSearchParams (requires Suspense + 'use client'), navigation (Link, redirect, useRouter), cookies/headers access, and 'use client' directive. Activates when prompt mentions useSearchParams, Suspense, navigation, routing, Link component, redirect, pathname, searchParams, cookies, headers, async components, or 'use client'. Essential for avoiding mixing server/client APIs.

Convert MCP servers into standalone Bash-invokable scripts. Use when user wants to make an MCP server usable as bash commands, convert MCP to CLI, or wrap MCP tools for agent use.

This skill should be used when configuring or using the OpenCode CLI for headless LLM automation. Use when the user asks to "configure opencode", "use opencode cli", "set up opencode", "opencode run command", "opencode model selection", "opencode providers", "opencode vertex ai", "opencode mcp servers", "opencode ollama", "opencode local models", "opencode deepseek", "opencode kimi", "opencode mistral", "fallback cli tool", or "headless llm cli". Covers command syntax, provider configuration, Vertex AI setup, MCP servers, local models, cloud providers, and subprocess integration patterns.

Control Tuya devices via local Home Assistant (tuya-local) or Tuya Cloud using the tuya-hub Go CLI.

This skill provides guidance for implementing robust Qdrant vector database integration with RAG (Retrieval Augmented Generation) systems, including proper async client handling, error management, and performance optimization.

Claude Code native tools reference. Prefer native tools over bash commands for file operations, search, and orchestration.

Implement comprehensive input validation with server-side security, client-side UX feedback, sanitization, and consistent error messages. Use this skill when validating user input in forms, API endpoints, or data processing. When writing validation rules for data types, formats, ranges, or required fields. When sanitizing input to prevent injection attacks (SQL, XSS, command injection). When providing field-specific error messages to users. When implementing validation at system boundaries like API endpoints or background jobs.

Intent-based code discovery for CLI AI agents using semantic search MCP tools. Use when finding code by what it does (not what it's called), exploring unfamiliar areas, or understanding feature implementations. Mandatory for code discovery tasks when you have MCP access.

Analyze and optimize existing ClickHouse pipelines, schemas, and queries. Use when reviewing ClickHouse performance, auditing table designs, troubleshooting slow queries, or improving data ingestion patterns.
