Hook creation and management system for React, Vue, and other frameworks with automated hook generation, testing, and documentation.

Default testing standard for all implementation work - ensures code actually works through mandatory execution validation before confirming to user. Applies automatically whenever writing, modifying, debugging, or implementing any code (scripts, APIs, UI, configs, data operations, logic changes). This is the baseline expectation, not an optional extra - every implementation must be verified through actual execution, not assumed correct.

Set up and improve WebF app tests with Vitest and React Testing Library. Use when the user mentions Vitest, React Testing Library, unit tests, component tests, “testing trophy”, or asks to add/fix tests in a Vite/React/TS WebF app.

Use when user wants to add new combat mechanics, damage formulas, status effects, mitigation logic, turn phases, or refactor existing combat code. Guides through proper separation of pure calculations vs state management.

Optimizes token usage and context management for large tasks, cleanup operations, multi-step workflows, code audits, and complex agent operations. Automatically triggers when handling cleanup commands, large codebase analysis, multi-file operations, or tasks requiring multiple subagents. Enforces efficient context usage while maintaining quality results.
