Comprehensive Python engineering guidelines for writing production-quality Python code. This skill should be used when writing Python code, performing Python code reviews, working with Python tools (uv, ruff, mypy, pytest), or answering questions about Python best practices and patterns. Applies to CLI tools, AI agents (langgraph), and general Python development.
Product discovery framework based on Teresa Torres' "Continuous Discovery Habits". Use when you need to: (1) build an opportunity solution tree from desired outcomes, (2) identify and prioritize customer opportunities, (3) design assumption tests for product ideas, (4) structure customer interview snapshots, (5) map assumptions to experiments, (6) move from output-driven to outcome-driven product development, (7) map current-state customer experiences, (8) build a weekly discovery habit.
Creates pytest fixtures following project patterns including factory fixtures, async fixtures, and multi-layer organization. Use when setting up test fixtures, creating test data, organizing test utilities, or structuring conftest.py files. Works with Python test files, pytest configuration, and .py test utilities.
TypeScript, React, and Node.js coding standards: naming, types, hooks, components, error handling, refactoring, code review. Use when creating/editing TS/JS/React files, naming variables or components, designing API endpoints, handling async, structuring components, or when the user asks "how should I name...", "what's the best way to...", "is this good practice...", "can you review this code". Keywords: TypeScript, React, hooks, React Query, Jest, RTL, naming, immutability. Do not load for: CSS-only changes, documentation writing, JSON config edits, shell scripts.
Generate Go validator implementations following GO modular architecture conventions (interface-first design, Fx DI, stateless validation). Use when creating validation logic in internal/modules/<module>/validator/ - password validation, email validation, input sanitization, business rule validation, or any domain validation that encapsulates validation rules and returns typed errors.
Executes browser-based user workflows from /workflows/browser-workflows.md using Claude-in-Chrome MCP. Use this when the user says "run browser workflows", "execute browser workflows", or "test browser workflows". Tests each workflow step by step, captures before/after screenshots, documents issues, and generates HTML reports with visual evidence of fixes.
Executes web app workflows in Safari on the iOS Simulator from /workflows/ios-workflows.md. Use this when the user says "run ios workflows", "execute ios workflows", or "test ios workflows". Tests each workflow step by step in mobile Safari, captures before/after screenshots, documents issues, and generates HTML reports with visual evidence of fixes.
Critically review terminal user interfaces for UX quality, responsiveness, visual design, and interactivity. Use when asked to "review my TUI", "test my TUI UX", "audit my terminal UI", "check TUI responsiveness", "review TUI keybindings", "check interactivity", or any request to evaluate the user experience quality of a ratatui/crossterm/ncurses-based terminal application. Launches the TUI in tmux, systematically tests 10 dimensions (responsiveness, input conflicts, visual clarity, navigation, feedback loops, error states, layout, keyboard design, permission flows, visual design & color), and produces a graded report with screenshots and specific findings. Benchmarks against Claude Code, OpenCode, and Codex — the three best-in-class AI terminal UIs.
Guides strict Test-Driven Development (TDD) using the Red-Green-Refactor cycle. Ensures no production code is written without a prior failing test. Use this skill when implementing new features, fixing bugs, or refactoring code to ensure high test coverage and design quality. Triggers on phrases like 'TDD', 'write tests first', 'test-driven', 'red-green-refactor', 'watch it fail', 'test first', or 'behavior driven'.
This skill should be used when the user asks to "debug the electron app", "connect playwright to VoiceTree", "take screenshots of the running app", "interact with the live UI", "inspect the running application", or "test UI elements live". Provides step-by-step instructions for connecting Playwright MCP to a running Electron app for live debugging and automation.
Generate unit and integration tests for API routes, utilities, React components, and hooks. Use when asked to generate tests, write unit tests, create integration tests, add test coverage, or test a component/route/function.
Run mobile app tests on cloud or local devices via the FinalRun MCP server. Use when: (1) uploading app binaries, (2) running tests or suites on cloud devices, (3) running tests on local devices.
