# Project Guidelines Skill (Example) This is an example of a project-specific skill. Use this as a template for your own projects. Based on a real production application: [Zenith](https://zenith.chat) - AI-powered customer discovery platform. --- ## When to Use Reference this skill when working on the specific project it's designed for. Project skills contain: - Architecture overview - File structure - Code patterns - Testing requirements - Deployment workflow --- ## Architecture Overview
Use this skill when adding authentication, handling user input, working with secrets, creating API endpoints, or implementing payment/sensitive features. Provides comprehensive security checklist and patterns.
Automatically extract reusable patterns from Claude Code sessions and save them as learned skills for future use.
Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction.
# Verification Loop Skill A comprehensive verification system for Claude Code sessions. ## When to Use Invoke this skill: - After completing a feature or significant code change - Before creating a PR - When you want to ensure quality gates pass - After refactoring ## Verification Phases ### Phase 1: Build Verification ```bash # Check if project builds npm run build 2>&1 | tail -20 # OR pnpm build 2>&1 | tail -20 ``` If build fails, STOP and fix before continuing. ### Phase 2: Type Check
ClickHouse database patterns, query optimization, analytics, and data engineering best practices for high-performance analytical workloads.
# Eval Harness Skill A formal evaluation framework for Claude Code sessions, implementing eval-driven development (EDD) principles. ## Philosophy Eval-Driven Development treats evals as the "unit tests of AI development": - Define expected behavior BEFORE implementation - Run evals continuously during development - Track regressions with each change - Use pass@k metrics for reliability measurement ## Eval Types ### Capability Evals Test if Claude can do something it couldn't before: ```mark
Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes.
