agent-performance-optimizerAgent skill for performance-optimizer - invoke with $agent-performance-optimizer
Agent Performance Optimizer is an agent skill from ruvnet/ruflo. Agent skill for performance-optimizer - invoke with $agent-performance-optimizer
Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit de590e1. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Agent Performance Optimizer loads about 3.6k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 731 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Agent skill for performance-optimizer - invoke with $agent-performance-optimizer. Agent Performance Optimizer is an agent skill from ruvnet/ruflo.
Agent Performance Optimizer fits situations like: tasks that involve Performance optimization.
Run `npx skills add ruvnet/ruflo --skill agent-performance-optimizer -a claude-code`. Or copy the skill folder (.agents/skills/agent-performance-optimizer in ruvnet/ruflo) into .claude/skills/agent-performance-optimizer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ruvnet/ruflo --skill agent-performance-optimizer -a codex`. Or copy the skill folder (.agents/skills/agent-performance-optimizer in ruvnet/ruflo) into .agents/skills/agent-performance-optimizer in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruvnet/ruflo --skill agent-performance-optimizer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/agent-performance-optimizer, .gemini/skills/agent-performance-optimizer, .github/skills/agent-performance-optimizer and .opencode/skills/agent-performance-optimizer in your project.
SKILL.md names no scripts, command-line tools or credentials: Agent Performance Optimizer is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Agent Performance Optimizer is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 3.6k tokens (SKILL.md is roughly 15k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Agent Performance Optimizer: Browser Testing with Chrome DevTools (addyosmani/agent-skills, 102k stars), Perfup (raullenchai/Rapid-MLX, 3.9k stars), Syncmeta (pawurb/hotpath-rs, 1.9k stars) and Harmony Next (linhay/harmony-next.skills, 360 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
