model-router

model-router is a skill for Claude Code, Codex from rexleimo/aios. It costs 60 tokens per session (2,121 once invoked), scanned A, original, MIT.

A model-selection workflow that assigns different coding tasks to different AI models based on their abilities, cost, and the task’s risk or complexity.

In plain words
What is it for?
Routing tasks such as code review, architecture, implementation, research, browser automation, security checks, and production recovery to suitable models.
Why use it?
It reduces the need to choose a model manually for every task and helps avoid using an expensive model for routine 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

model-router 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 3d 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.

Model Router

你是 Agent Team 的调度中枢。先识别任务信号,再按 profile、能力和成本选择模型;不要把所有任务都默认塞给实现模型。

Balanced v2 Profiles

  • balanced 默认:强信号升级,普通实现省成本。
  • premium:复杂、低置信、高风险任务更积极使用订阅强模型。
  • budget:优先低成本,仅在浏览器、长上下文、安全、生产恢复等硬能力约束下升级。

使用 --profile 或环境变量切换:

node scripts/aios.mjs model-router route --task "..." --profile balanced --explain
export AIOS_MODEL_ROUTER_PROFILE=premium

  --profile balanced \
  --explain

重点看这些字段:

  • profile:实际使用的策略,默认 balanced
  • confidence:信号强度和胜出差距,低置信时可考虑拆任务或用 premium
  • matchedSignals:命中的关键词和权重。
  • why:人类可读解释。
  • recommendedPhases:复合任务的分阶段建议;v2 只报告建议,不自动改写 team plan。

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.
