What it does
Performance is an agent skill from Sidiora-Labs/centra-llm-agents. Performance optimization guidelines for React/React Native applications. Use when optimizing app performance, fixing UI freezes/lag, reducing re-renders, handling concurrent operations, or analyzing performance bottlenecks. Triggers on performance, optimization, optimize, slow, lag, freeze, hang, jank, stutter, memory, leak, concurrent, batching, batch, memoization, memo, bridge, windowSize, contentVisibility, FlashList, re-render, fps, tti, bundle.
Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/rules/performance.md`).
It sits in Mobile, covering Performance optimization, Cross-platform mobile apps and Mobile performance. It works with React Native and React. The repository describes itself as: A stateful AI operating system for serious, long-horizon work.
When your agent uses it
- Optimizing app performance
- Fixing UI freezes/lag
- Reducing re-renders
- Handling concurrent operations
Example prompts
- “/performance”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob
What it can do on your machine
Read from SKILL.md and the folder at commit 01c6aef. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Performance loads about 778 tokens when it runs, and up to ~6.1k if it reads all its reference files. Until then it costs about 116 tokens; SKILL.md has 169 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.
Safety
Auto-check passed
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 169 words (~778 tokens).
“Performance optimization patterns and best practices for React/React Native applications.”

Questions about Performance
What does Performance do?
Performance optimization guidelines for React/React Native applications. Performance is an agent skill from Sidiora-Labs/centra-llm-agents. Performance optimization guidelines for React/React Native applications.
When should I use Performance?
Performance fits situations like: optimizing app performance; fixing UI freezes/lag; reducing re-renders; handling concurrent operations.
How do I install Performance in Claude Code?
Run `npx skills add Sidiora-Labs/centra-llm-agents --skill performance -a claude-code`. Or copy the skill folder (protocol/skills/performance in Sidiora-Labs/centra-llm-agents) into .claude/skills/performance in your project. Claude Code loads it when a task matches its description.
How do I install Performance in Codex?
Run `npx skills add Sidiora-Labs/centra-llm-agents --skill performance -a codex`. Or copy the skill folder (protocol/skills/performance in Sidiora-Labs/centra-llm-agents) into .agents/skills/performance in your project. Codex loads it when a task matches its description.
Can I use Performance in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Sidiora-Labs/centra-llm-agents --skill performance -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/performance, .gemini/skills/performance, .github/skills/performance and .opencode/skills/performance in your project.
What does Performance need to run?
SKILL.md names no scripts, command-line tools or credentials: Performance is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Glob.
Does Performance access the network?
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.
Is Performance safe to install?
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.
What licence does Performance use?
Performance has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Performance use?
About 778 tokens (SKILL.md is roughly 3.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 5.4k tokens, read only when the agent opens those files.
What are the alternatives to Performance?
Skills that share tags, products or a category with Performance: Argent React Native Optimization (bbplayer-app/BBPlayer, 1.1k stars), React Native Best Practices (callstackincubator/agent-skills, 1.7k stars), React Native Expert (tech-leads-club/agent-skills, 7k stars) and Argent React Native Profiler (bbplayer-app/BBPlayer, 1.1k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Performance?
Sidiora-Labs (a GitHub organization) maintains it in Sidiora-Labs/centra-llm-agents, which has 115 GitHub stars. The repository holds 13 skills in this directory. The repository was last updated on September 18, 2026.
