AI agent skills for performance optimization
Performance skills are valuable mainly for the discipline of measuring first. A good one refuses to suggest a change until there is a number attached to the problem, and knows the difference between a p50 and a p99 complaint. The ones to avoid hand out a list of generic optimizations — adding a cache to code that was never slow is how you get a correctness bug in exchange for nothing.

heshamfs Bundle Performance ProfilingIdentify computational bottlenecks, analyze parallel scaling, estimate memory requirements, and generate optimization recommendations for materials simulations — parse timing logs to find dominant phases (solver, assembly, I/O), evaluate strong and weak scaling efficiency, profile memory from mesh and field parameters, and detect bottlenecks with actionable fix suggestions. Use when a simulation is running slower than expected, investigating MPI scaling efficiency, planning HPC resource allocation, deciding whether to tune the preconditioner or reduce I/O frequency, or estimating if a problem fits in available RAM, even if the user only says "my simulation is too slow" or "how many nodes do I need."

How to install a performance optimization skill
- Compare the skills. Read the performance optimization skills below — each page shows the full SKILL.md, its safety verdict, and the capabilities it declares.
- Install it. Run npx skillmds@latest add <owner>/<name>. The CLI writes the skill into every agent directory it detects, or use --agent to pin one.
- Use it. Restart your agent. It loads the skill on demand the next time you ask for something that matches — you do not have to name the skill.
What makes a good performance optimization skill?
Performance skills are valuable mainly for the discipline of measuring first. A good one refuses to suggest a change until there is a number attached to the problem, and knows the difference between a p50 and a p99 complaint. The ones to avoid hand out a list of generic optimizations — adding a cache to code that was never slow is how you get a correctness bug in exchange for nothing.
Every skill listed here is a plain SKILL.md file in the format Anthropic documents for Agent Skills, read unchanged by Cursor, OpenAI Codex and 60+ agents. Each passes a safety review before it is publicly listed; the verdict and declared capabilities are on every skill's page.
Frequently asked questions
What is an agent skill for performance optimization?
Performance skills are valuable mainly for the discipline of measuring first. A good one refuses to suggest a change until there is a number attached to the problem, and knows the difference between a p50 and a p99 complaint. The ones to avoid hand out a list of generic optimizations — adding a cache to code that was never slow is how you get a correctness bug in exchange for nothing.
Can a performance skill profile my app?
It can tell the agent which profiler to run and how to read the output, but the measurement happens through tools you already have. Skills that only reason about code without a measurement step are best treated as review checklists.
Which agents can use these performance optimization skills?
Any agent that reads SKILL.md files: Claude Code, Claude.ai, Cursor, OpenAI Codex, Windsurf, OpenCode and 60+ others. The format is not vendor-specific, so the same file works everywhere — each agent just keeps its skills in a different directory, listed at /agents.
Are these performance optimization skills free?
Yes. Searching, reading and installing skills on SkillMD is free and needs no account. Individual skills carry their own licence, shown on each skill's page.
