performance-profiler SKILL.md skillA
performance-profiler from latestaiagents/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add latestaiagents/agent-skills/performance-profiler@git:20260205.a0b8780Pins git:20260205.a0b8780 in mdr.lock. Pin the fingerprint instead.

Use this skill when investigating performance issues. Activate when the user has slow code, needs to find performance bottlenecks, wants to profile application performance, is optimizing response times, or investigating memory usage.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Performance Profiler
Identify and resolve performance bottlenecks in your code.
## When to Use
- Application is slower than expected
- Looking for optimization opportunities
- Memory usage is growing unexpectedly
- Users report slow response times
- Preparing for load testing
## Performance Investigation Workflow
```
┌─────────────────────────────────────────────────────────────┐
│ 1. MEASURE - Baseline current performance │
├─────────────────────────────────────────────────────────────┤
│ 2. PROFILE - Identify where time is spent │
├─────────────────────────────────────────────────────────────┤
│ 3. ANALYZE - Understand why it's slow │
├─────────────────────────────────────────────────────────────┤
│ 4. OPTIMIZE - Make targeted improvements │
├─────────────────────────────────────────────────────────────┤
│ 5. VERIFY - Confirm improvement without regression │
└─────────────────────────────────────────────────────────────┘
```
## Measurement Techniques
### Basic Timing
```typescript
// Simple timing
console.time('operation');
await slowOperation();

How to install
mdr add latestaiagents/agent-skills/performance-profiler@sha256:8489aad1b8b841bbThe line at the top of this page pins the label git:20260205.a0b8780, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
