CLI Tools

Implement robust error handling in client-side JavaScript code to gracefully manage failures in static site operations. Use this skill when working with error scenarios in API calls, DOM manipulation, data parsing, and user interactions.

Meteor Client addon development for Minecraft. Use when creating, updating, or working with Meteor Client addons - a Fabric mod framework for Minecraft. Covers workspace setup from the template repository, updating addons when Minecraft/Meteor versions change, finding reference implementations from verified addons, and understanding Meteor's addon structure and APIs.

Debug and fix failures in Taskcluster tasks. Use this skill when the user asks to debug a task, fix a failing task, or investigate task errors/failures. This skill uses the Taskcluster CLI to fetch task logs and definitions, analyzes errors, and uses `taskgraph load-task --develop` to reproduce and debug issues locally. Invoke this for any request involving Taskcluster task debugging, task failures, or when given a task ID to investigate.

Generate FOSMVVM ViewModels - the bridge between server-side data and client-side Views. Use when creating new screens, pages, components, or any UI that displays data.

Plans safe API evolution with versioning strategies, client migration guides, deprecation timelines, and backward compatibility considerations. Use for "API versioning", "deprecation planning", "API evolution", or "breaking changes".

Interact with the Text Processing AI Agent. Use when you need text analysis, formatting, or processing capabilities from the agent.

Command-line fuzzy finder for interactive filtering of any list. Use when interactively selecting files, searching command history (CTRL-R), creating selection interfaces in scripts, building interactive menus, or integrating fuzzy search with tools like ripgrep, fd, and git. Triggers on mentions of fzf, fuzzy finder, ** completion, interactive filtering, or shell keybindings CTRL-T/CTRL-R/ALT-C.

Use when profiling native macOS or iOS apps with Instruments/xctrace. Covers correct binary selection, CLI arguments, exports, and common gotchas.

Build CLI tools using Go with Cobra and Viper. Use for implementing agentctl commands, interactive prompts, configuration management, and output formatting. Triggers on "CLI", "agentctl", "command line", "cobra", "terminal application", "interactive prompt", or when implementing spec/009-developer-experience.md CLI section.

Working with Terraform configuration, CLI, modules, and providers. Use when writing or reviewing HCL configuration, managing infrastructure as code, debugging Terraform plans/applies, or working with Terraform-related tools.

Use this skill when developing Next.js/React frontend code for Brokle. Includes components, pages, hooks, API clients, stores, or any frontend features.

Multi-agent coordination via agent-mail CLI. Use when communicating with other agents, coordinating file access, sending/receiving messages, checking inbox, or reserving files. Triggers on "send message to agent", "check inbox", "reserve files", "coordinate with other agents", multi-agent workflows, file reservations, acknowledgements, "list agents", "delete agent", "clean up agents", "purge agents".

Control vehicle with natural language. Use when user wants to warm up/cool down the car, lock/unlock doors, start/stop engine, check battery/fuel/location/status, or control charging. Translates phrases like "warm up the car" into mcs CLI commands.

This skill enables Claude to monitor and analyze application error rates to improve reliability. It is used when the user needs to track and understand errors occurring in their application, including HTTP errors, application exceptions, database errors, external API errors, background job errors, and client-side errors. Use this skill when the user asks to "monitor errors", "analyze error rates", "track application errors", or requests help with "error monitoring". It sets up comprehensive error tracking and alerting based on defined thresholds.

Google Gemini CLI fundamentals for code analysis, review, and validation. Use when (1) executing gemini commands for code review/analysis, (2) configuring models (gemini-3-flash-preview (default)/gemini-3-pro-preview (complex only)), output formats (text/json/stream-json), or sandbox modes, (3) managing Gemini sessions with /chat save/resume, (4) integrating Gemini into automation scripts and CI/CD pipelines. Do NOT use for orchestration patterns (use gemini-claude-loop instead).

Comprehensive Rust development guidelines based on 6 months of code reviews. Use when writing Rust code, debugging Rust issues, or reviewing Rust PRs. Covers error handling, file I/O safety, type safety patterns, performance optimization, common footguns, and fundamental best practices. Perfect for both new and experienced Rust developers working on CLI tools, hooks, or production code.

Standalone CLI bridge - launch external AI CLIs (gemini, codex, claude) directly without MCP server. Use when you need to delegate tasks to specialized CLI tools with their own context windows. Supports role-based prompts and file references.

Use the @steipete/oracle CLI to bundle a prompt plus the right files and get a second-model review (API or browser) for debugging, refactors, design checks, or cross-validation.
