route

route is a skill for Claude Code from ypollak2/llm-router. It costs 16 tokens per session (883 once invoked), scanned A, original, MIT.

A task router that chooses which language model should handle a request based on its type and difficulty.

In plain words
What is it for?
It helps route research, writing, and other task categories to the configured models, either through /route or automatically when a prompt is submitted.
Why use it?
It removes the need to decide manually which model to use for each prompt. Uncertain requests can be classified by local or low-cost backup models.

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

route 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.

/route — Smart LLM Task Router

Route any task to the optimal LLM automatically.

Usage

/route <task description>

Auto-Classification

Most prompts are classified automatically by the UserPromptSubmit hook — no /route needed. The hook uses a multi-layer classification chain:

  1. Heuristic scoring (instant, free) — Three signal layers accumulate evidence:

    • Intent patterns (+3) — action verbs and task markers
    • Topic patterns (+2) — domain-specific nouns
    • Format patterns (+1) — structural and temporal cues
    • High-confidence match (score >= 4) routes immediately
  2. Ollama local LLM (~1s, free) — When heuristics are uncertain, qwen3.5 classifies locally via the chat API with thinking disabled

  3. Cheap API model (~$0.0001) — If Ollama is unavailable, Gemini Flash or GPT-4o-mini classifies

  4. Weak heuristic / auto fallback — Last resort: low-confidence heuristic match or llm_route (full LLM classifier)

Task Categories

The consolidated llm(prompt=..., task=..., tier=...) tool is the front door for all of these — task= picks the specialization, tier= (fast/balanced/best) picks the cost tier:

Category Call Signals
Research llm(task="research") Current events, news, funding, trends, market data, rankings
Generate llm(task="generate") Writing, drafting, brainstorming, emails, articles, translations
Analyze llm(task="analyze") Evaluation, debugging, comparison, trade-offs, code review
Code llm(task="code") Implementation, refactoring, building, bug fixes
Query llm(task="query") (or task="auto") Simple questions, definitions, explanations
Image llm_image Visual generation, design, artwork

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.
