performance-validator

performance-validator is an agent for coding agents from aself101/agents-and-pipelines. It costs 57 tokens per session (8,496 once invoked), scanned A, original, no licence file.

A performance test that measures how a system behaves under realistic demand, including response times, workload capacity, simultaneous users, resource use, and stress-related slowdown.

In plain words
What is it for?
Use it for load testing, response-time profiling, capacity checks, concurrency testing, and finding how performance degrades under stress.
Why use it?
It replaces guesses about speed and scale with measurements taken while the system is busy.

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-validator 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 4d 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.

What this file has done since we first saw it

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.
