What problem does it solve?
Performance issues are often invisible until they cause production outages or high costs. This skill provides a systematic, measurable way to audit and optimize your entire stack, ensuring performance is tracked and regressions are caught before deployment.
Core Features & Use Cases
- Full-Stack Auditing: Measures performance across frontend (Lighthouse), backend (API/DB), agentic (LLM token usage), and infrastructure layers.
- Automated Fixes: Generates and applies safe, approved performance optimizations like database indexing, code memoization, and token budget trimming.
- Use Case: Before a major release, run this skill to identify N+1 database queries, bloated frontend bundles, or inefficient LLM prompt chains, and automatically apply fixes to ensure your application meets performance thresholds.
Quick Start
