# CertainLogic Smart Router
> **[Company Brain Core OS](https://certainlogic.ai/brain) — Free, local, deterministic knowledge base for your agent. Start here before optimizing routing.**
**Route queries to the right model tier. Save money without thinking about it.**
v1.0.2
**Built and dogfooded by CertainLogicAI** — Keyword routing. Not AI. Not magic. Just cheaper.
---
## Part of the CertainLogic Stack
This skill works **standalone**. You don't need anything else to start saving money on LLM calls.
**Works even better with [Company Brain Core OS](https://certainlogic.ai/brain)** (`clawhub install company-brain-os`):
- Brain stores your routing patterns and learns from usage
- **TRE (Token Reduction Engine)** — catches deterministic queries before they hit the router
- **AgentPathfinder** — audits which routing decisions led to good outcomes
**All three are independent.** Pick the one that solves your problem. Add others when you need them.

## How It Works
Smart Router uses **keyword-based routing** to decide which LLM tier to hit:
| Tier | Model | Price | Best For |
|------|-------|-------|----------|
| **Fast** | GPT-4o-mini / Haiku | $0.15/million tokens | Simple queries, coding, classification |
| **Standard** | GPT-4o / Sonnet | $2.50/million tokens | Complex reasoning, analysis |
| **Deep** | GPT-4o-latest / Opus | $15.00/million tokens | Critical decisions, audits |
### Example Routing Rules
```yaml
# Simple routing rules
"code review" → fast # 90% of code reviews don't need deep reasoning
"security audit" → deep # Always use best model for security
"summarize" → fast # Summarization is perfect for cheap models
"compare alternatives" → standard # Needs reasoning, not maximum depth
```
### Cost Savings
**Without Router:** All queries go to GPT-4o → $2.50/million tokens
**With Router:** 70% fast + 25% standard + 5% deep → **~$0.80/million tokens**
**Savings: ~70% on token costs** (measured on our internal workload)

## Standalone Usage
```bash
clawhub install certainlogic-smart-router
```
Then in your agent config:
```yaml
smart_router:
default_tier: standard
rules:
- pattern: "review|check|validate"
tier: fast
- pattern: "audit|security|critical"
tier: deep
- pattern: "compare|analyze|choose"
tier: standard
```

## Integration with Company Brain Core OS
When Brain is installed, Smart Router gets smarter:
- **Cached queries** → skips router entirely (0 cost)
- **Known patterns** → Brain remembers which tier worked best for each query type
- **Query classification** → Brain's intent classifier improves routing accuracy
```bash
# Install both
clawhub install company-brain-os certainlogic-smart-router
# Brain learns from router decisions, router improves from brain cache
```
