CLI Tools

Rope-first workflow for ANY mechanical Python rename/move (functions/methods/classes/variables/modules/packages), updating imports/references via scripts/rope_refactor.py; use even for small renames; only fallback if rope fails/dynamic imports.

Use for WordPress Playground workflows: fast disposable WP instances in the browser or locally via @wp-playground/cli (server, run-blueprint, build-snapshot), auto-mounting plugins/themes, switching WP/PHP versions, blueprints, and debugging (Xdebug).

Use when the user asks about WordPress codebases (plugins, themes, block themes, Gutenberg blocks, WP core checkouts) and you need to quickly classify the repo and route to the correct workflow/skill (blocks, theme.json, REST API, WP-CLI, performance, security, testing, release packaging).

Invoke Google Gemini CLI for complex reasoning tasks, research, and AI assistance. Trigger phrases include "use gemini", "ask gemini", "run gemini", "call gemini", "gemini cli", "Google AI", "Gemini reasoning", or when users request Google's AI models, need advanced reasoning capabilities, research with web search, or want to continue previous Gemini conversations. Automatically triggers on Gemini-related requests and supports session continuation for iterative development.

Write functional tests for Symfony controllers and HTTP endpoints using WebTestCase, BrowserKit, and test clients

Initialize a dagster project using the create-dagster cli. Create a dagster project, uv virtual environment, and everything needed for a user to run dg dev or dg check defs successfully. (project)

Create a custom Dagster Component with demo mode support, realistic asset structure, and optional custom scaffolder using the dg CLI. Use this skill if there is no Component included in an existing integration or if Dagster does not have the integration.

Carmack-level plan review via rp-cli context builder + chat. Use when reviewing implementation plans, architecture docs, or design specs. Triggers on mentions of plan review, design review, or architecture review.

Implement client-side routing using React Router, Vue Router, and Angular Router. Use when building multi-page applications with navigation and route protection.

This skill should be used when editing Python code in the erk codebase. Use when writing, reviewing, or refactoring Python to ensure adherence to LBYL exception handling patterns, Python 3.13+ type syntax (list[str], str | None), pathlib operations, ABC-based interfaces, absolute imports, and explicit error boundaries at CLI level. Also provides production-tested code smell patterns from Dagster Labs for API design, parameter complexity, and code organization. Essential for maintaining erk's dignified Python standards.

Debug client-side issues using browser developer tools. Identify JavaScript errors, styling issues, and performance problems in the browser.

Token-efficient codebase exploration using RepoPrompt CLI. Use when user says "use rp to..." or "use repoprompt to..." followed by explore, find, understand, search, or similar actions.

Bash shell scripting. Use when automating tasks, writing system scripts, or configuring VMs.

Use the Gunshi library to create command-line interfaces in JavaScript/TypeScript.

Automate browser interactions using Selenium WebDriver. Use this skill when you need to interact with dynamic JavaScript-heavy websites, fill forms, click buttons, handle authentication, or scrape content that requires browser rendering. NOT needed for static HTML parsing or processing already-fetched content.

Bash/shell script writing. Use when automating tasks, creating build scripts, or system administration.

Execute shell commands from Python. Use for running CLI tools, scripts, or system commands.

Check and lint Rust/TypeScript code using justfile tasks (just check-crate, just clippy-crate). Use after code changes, when user mentions compilation, type checking, linting, clippy warnings, or needs to validate code quality. Runs cargo check and clippy with proper flags.

Launch a Streamlit GUI for Task Master tasks.json editing. Use when users want a visual interface instead of CLI/MCP commands.

Apply effective software quality consultancy practices. Use when consulting, advising clients, or establishing consultancy workflows.
