llm-router

llm-router is a skill for Claude Code, Codex from AIsa-team/agent-skills. It costs 61 tokens per session (3,522 once invoked), scanned A, original, Apache-2.0.

A service and skill for routing requests to many AI language models through one OpenAI-compatible API and API key.

In plain words
What is it for?
It is for model switching, comparing responses, image analysis, choosing models by cost or task, and setting fallback routes when a model fails.
Why use it?
It avoids managing separate provider connections when switching between models such as GPT, Claude, Gemini, Qwen, DeepSeek, or Grok.

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-router 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/llm_router_client.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.
