AI RULEBOOKVitest & Playwright TDD Windsurf Cascade Rules
Production-grade architectural rulebook for Vitest & Playwright TDD. Engineered to eliminate LLM hallucinations, enforce strict deterministic conventions, and prevent architectural drift across Cursor IDE, Claude Code CLI, and autonomous multi-agent pipelines.
.windsurf/rules/tdd-specialist.mdFailure Patterns Prevented for Vitest & Playwright TDD
AI coding tools often generate code without accompanying tests. These rules force Cursor to write failing tests first and mock external I/O cleanly.
- Invokes deprecated or removed APIs from older model training weights
- Generates conflicting configuration files and invalid imports
- Silently drops type-safety, boundaries, or transaction isolation
How to Install Vitest & Playwright TDD Windsurf Cascade Rules via Terminal
Step 1: Open Project Directory & Verify Target Placement
Open your terminal and navigate to your project root folder where the .windsurf/rules/tdd-specialist.md file will reside. Ensure the file is placed at the exact path below relative to your project root so the AI engine automatically loads it:
Step 2: Fetch Rule File via Terminal Command
Run curl, PowerShell, or wget to stream the rule directly from the DevScratchpad raw API endpoint and write it to .windsurf/rules/tdd-specialist.md:
Terminal One-Liner Install
Run directly in your project root to stream and write this rule file with one command.
mkdir -p ".windsurf/rules" && curl -fsSL "https://www.devscratchpad.tech/api/raw/windsurf-rules/tdd-specialist" -o ".windsurf/rules/tdd-specialist.md"Step 3: Verify and Activate with AI Agent
Launch your AI coding assistant (Universal AI Assistants). The assistant will automatically discover .windsurf/rules/tdd-specialist.md in your repository and apply the architectural guardrails, type constraints, and verification protocols during code generation.
