latency-critical-systems

latency-critical-systems is a skill for Claude Code from findscripter/everything-skills. It costs 134 tokens per session (1,545 once invoked), scanned A, original, no licence file.

A guide for designing and improving systems where response freshness and high-percentile latency matter. Percentile latency, such as p95 or p99, shows how slow the slowest typical requests are.

In plain words
What is it for?
It helps analyse real-time dashboards, market-data flows, agent streams, gateways, queues, and caches, then define optimisation priorities and release safeguards.
Why use it?
It helps locate delays in the hot path and reduce slow responses without relying only on average timing.

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

latency-critical-systems 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 today.

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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
