profile SKILL.md skillA
profile from gufranco/claude-engineering-rules is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add gufranco/claude-engineering-rules/profile@git:20261013.7233f74Pins git:20261013.7233f74 in mdr.lock. Pin the fingerprint instead.

Performance profiling and bottleneck identification. Measures database statements and time per request on the running app, scans the code for bottleneck patterns, ranks findings by impact, and suggests specific optimizations. Use when user says "profile", "why is this slow", "find bottleneck", "performance issue", "slow query", "slow endpoint", "optimize", or needs to find what is causing poor performance. For benchmark comparisons, use /benchmark; for load testing, use /test perf; for general…
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
## Overview Performance profiling that measures what a slow request actually costs on the running app, scans the codebase for common bottleneck patterns, ranks findings by impact, and provides concrete fixes with code examples. A measured finding outranks a pattern match. Covers database queries, API latency, frontend loading, and algorithmic complexity. ## When to use - When a specific endpoint, page, or operation is slow. - When you need to find the highest-impact optimization targets before a release. - When database query performance is degrading. - When startup time or build time is unexpectedly long. ## When NOT to use - For benchmark comparisons between implementations. Use `/benchmark` instead. - For HTTP load testing with concurrent users. Use `/test perf` instead. - For general code quality review. Use `/review` instead. - For security scanning. Use `/audit` instead. ## Arguments This skill accepts optional arguments after `/profile`: - No arguments: scan the project for common bottleneck patterns across all categories. - `<path>`: profile a specific file, directory, or module. Example: `/profile src/services/order.service.ts`. …

How to install
mdr add gufranco/claude-engineering-rules/profile@sha256:8b336602adad865fThe line at the top of this page pins the label git:20261013.7233f74, 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.
