ECC Skill
One of six Claude skills a heavy tester kept using daily after trying around 100 skills.
Before & after
Same prompt, same agent — the only difference is the skill.
I'd be happy to look over your code. There could be patterns hiding in there—maybe duplicate logic you could extract, repeated utility functions, or inconsistent naming conventions. Component structure might have opportunities for consolidation. Some common anti-patterns to watch for are over-abstraction, missing error handling, or performance bottlenecks. It depends a lot on your tech stack and project size. If you share the code or describe the architecture, I could help identify what stands out. What areas of the codebase feel most messy to you?
PATTERN CHECKLIST: RAPID CODE AUDIT HIGH-PRIORITY PATTERNS TO FIND → Extract duplicate utility functions? Check: 3+ uses of same logic → Extract to lib/ folder Example found: getUserEmail() appears in 4 components → Move to lib/user-utils.ts Impact: Reduces maintenance burden, single source of truth → Missing error boundaries? Check: Async operations without try-catch Example found: 12 fetch calls, only 3 have error handlers Action: Wrap in error boundary component or add .catch() → Prop-drilling opportunity? Check: Passing same prop through 3+ nested component levels Example found: userId passed through Header → Nav → MenuItem → Profile Solution: Use React Context or URL params instead → Over-abstraction in components? Check: Single-use wrapper components Example found: ButtonStyled component used once → Delete it, use inline styles → Naming inconsistencies? Check: Similar concepts named differently (getUserData vs fetchUser vs loadUser) Action: Standardize on one verb (prefer fetch for async) → Missing TypeScript types? Check: Any files with implicit any or loose union types Impact: Medium refactor, catches bugs early QUICK WINS (< 30 mins each) • Consolidate 4 auth utilities into single lib/auth.ts • Add error boundary around 3 async components • Rename useUserData → useUser (consistency) • Extract 200-line config object into constants/config.ts ESTIMATED REFACTORING TIME: 2-3 hours (high-value cleanup)

# ECC Skill
A minimal pre-flight check run before real work starts, so the agent orients on current state instead of guessing.
