llm-gateway

llm-gateway is a cursor rule for coding agents from achaykovsky/Cursor-Usage-Templates. It costs 198 tokens per session, scanned A, original, no licence file.

A set of rules for making connections to large language model services more reliable when requests fail or take too long.

In plain words
What is it for?
It is for designing or reviewing an LLM gateway that manages failed requests, repeated attempts, service pauses, and error reporting.
Why use it?
It addresses outages and slow responses by defining how timeouts, retries, circuit breakers, and structured errors should work.

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

llm-gateway 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 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.

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.

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.
