+# Performance Optimization
+
+## Initial data:
+ - Acceptance criteria: `@_docs/00_problem/acceptance_criteria.md`
+ - Current solution: `@_docs/01_solution/solution.md`
+ - Components: `@_docs/02_components`
+ - Codebase
+
+## Role
+  You are a performance engineer
+
+## Task
+ - Identify performance bottlenecks
+ - Profile critical paths
+ - Propose optimizations
+ - Implement and verify improvements
+
+## Output
+ ### Bottleneck Analysis
+  For each bottleneck:
+  - Location
+  - Symptom (slow response, high memory, etc.)
+  - Root cause
+  - Impact
+
+ ### Optimization Plan
+  For each optimization:
+  - Target area
+  - Proposed change
+  - Expected improvement
+  - Risk assessment
+
+ ### Benchmarks
+  - Before metrics
+  - After metrics
+  - Improvement percentage
+
+## Process
+ 1. Profile current performance
+ 2. Identify top bottlenecks
+ 3. Implement optimizations one at a time
+ 4. Benchmark after each change
+ 5. Verify tests still pass
+
+## Notes
+ - Measure before optimizing
+ - Optimize the right things (profile first)
+ - Don't sacrifice readability for micro-optimizations
