What it does
Performance is an agent skill from BuilderIO/agent-native. Keep app loads and interactions responsive as data grows. Use when a page feels slow, jumps, or lags, or when changing a data read, list, polling path, startup path, or performance-sensitive UI.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: A framework for building agentic apps.
When your agent uses it
- A page feels slow
- Changing a data read
- Performance-sensitive UI
Example prompts
- “/performance”
What it can do on your machine
Read from SKILL.md and the folder at commit be0d784. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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 1k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 589 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 589 words (~1,019 tokens).
“Find the cost that users actually wait on, then reduce it without weakening the result. A slow screen may be waiting on the server, moving too much data, serial reads, repeated computation, or browser rendering; measure before adding caches or…”
