perf-profiler is a skill for Claude Code, Kiro from Najeebullah3124/awesome-claude-universe. It costs 25 tokens per session (214 once invoked), scanned A, original, no licence file.

A tool for measuring CPU and memory use in running code and producing flame graphs, which show where execution time is spent.

In plain words
What is it for?
Use it to profile CPU and memory behavior and collect JFR or perf evidence for an investigation.
Why use it?
It helps locate hot paths instead of relying on assumptions about which code is slow or uses too much memory.

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

perf-profiler scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
