optimizing-performance
Analyzes and optimizes application performance across frontend, backend, and database layers. Use when diagnosing slowness, improving load times, optimizing queries, reducing bundle size, or when asked about performance issues.
npx skills add CloudAI-X/claude-workflow-v2 --skill optimizing-performance --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Optimizing Performance ### When to Load - **Trigger**: Diagnosing slowness, profiling, caching strategies, reducing load times, bundle size optimization - **Skip**: Correctness-focused work where performance is not a concern ## Performance Optimization Workflow Copy this checklist and track progress: ``` Performance Optimization Progress: - [ ] Step 1: Measure baseline performance - [ ] Step 2: Identify bottlenecks - [ ] Step 3: Apply targeted optimizations - [ ] Step 4: Measure again and compare - [ ] Step 5: Repeat if targets not met ``` **Critical Rule**: Never optimize without data. Always profile before and after changes. ## Step 1: Measure Baseline ### Profiling Commands ```bash # Node.js profiling node --prof app.js node --prof-process isolate*.log > profile.txt # Python profiling python -m cProfile -o profile.stats app.py python -m pstats profile.stats # Web performance lighthouse https://example.com --output=json ``` ## Step 2: Identify Bottlenecks ### Common Bottleneck Categories | Category | Symptoms | Tools | | -------- | -------------------------------- | ------------------------------- | | CPU | High CPU usage, slow computation | Profiler, flame graphs | | Memory |

What does the optimizing-performance skill do?
Analyzes and optimizes application performance across frontend, backend, and database layers. Use when diagnosing slowness, improving load times, optimizing queries, reducing bundle size, or when asked about performance issues.
How do I install it?
Run `npx skills add CloudAI-X/claude-workflow-v2 --skill optimizing-performance --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From CloudAI-X/claude-workflow-v2, a repository with 1,397 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
