Why Agent Loops Don't Warn — They Bill
How runaway tool traffic drives token cost — and where a gateway helps.
A single "research this topic" prompt can trigger dozens of fetches, searches, and re-reads. Each hop may re-send context to your model. The loop doesn't ask permission — it invoices.
The hidden multiplier
| Stage | What happens |
|---|---|
| Agent plans | Model chooses tools repeatedly |
| Tool output | Large HTML/JSON returns to context |
| Re-prompt | Same content sent again on the next turn |
| No ceiling | Budget guardrails often live too late (at the LLM API) |
SmartGate intervenes at the tool layer: compress prompts, deduplicate repeated chunks, enforce budget checks, and log every call for audit.
Practical first steps
- Connect SmartGate MCP before enabling long-running agents
- Use Activity Logs to see which tools dominate spend
- Set team budget alerts in the Dashboard
