performance-optimizer

performance-optimizer is an agent for Claude Code from bcefghj/forks-collection. It costs 48 tokens per session (3,050 once invoked), scanned A, original, no licence file.

A code-performance specialist that finds slow parts of an application and suggests or makes focused improvements.

In plain words
What is it for?
Use it to profile applications, reduce frontend bundle sizes, improve runtime speed, optimize rendering, and investigate high memory use.
Why use it?
It helps locate bottlenecks, memory leaks, large bundles, slow rendering, and inefficient algorithms without requiring manual investigation across the whole codebase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

performance-optimizer scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
