Adaptive Tool Router for AI Agents
Build a middleware layer that selects only the tools relevant to the current user intent before each model call. The product reduces token waste, keeps context windows cleaner, and can improve answer quality by preventing irrelevant tools from distracting the model.
Why this matters
You run an agent with dozens of tools because you want broad capability across chat, browser, file, automation, and code tasks. But every request drags the full tool catalog and large instructions into the prompt, so even a tiny ask starts with a huge token bill. Cost is only part of the problem. The model also has to reason through irrelevant options, which increases mistakes and makes the agent feel unstable. You can create stripped-down profiles, but that means guessing in advance which tools a future task might need. What you really want is software that decides, per request, which tools belong in context and leaves the rest out.
- · Built for Developers and small teams operating multi-tool AI agents in chat, automation, and coding workflows who pay meaningful monthly API bills..
- · Most likely monetization: SaaS subscription.

MVP Scope · 1–2 weeks
- Build an OpenAI-compatible proxy that logs incoming tools, prompt size, and response metadata.
- Implement a basic rules engine that maps user intent keywords to tool groups.
- Create a config format for custom tool groups and safe fallback behavior.
- Add request diffing to show tokens saved when tools are excluded.
- Test the proxy against two agent setups with 10 or more tools each.
- Add a simple classifier to rank likely tools from the latest user message and recent context.
- Build a web dashboard with savings per request and by tool category.
- Implement one-click rollback to full tool mode when confidence is low.
- Add experiment flags for side-by-side evaluation of full versus routed toolsets.
- Publish installation docs and a self-serve onboarding flow.
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1The strongest risk is trust: users may reject any optimizer that sometimes hides a needed tool and causes a failed task.
- 2Native provider improvements could compress the market if tool search becomes a standard feature across major APIs.
- 3The economic value may be less obvious for users whose providers already cache much of the repeated overhead.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion repeatedly centers on large fixed overhead from tool definitions and system instructions, with several participants independently confirming high token usage across versions and providers. Roughly half the comments point toward selective tool loading or searchable tool discovery as the most practical improvement. Multiple users also describe manual profile workarounds, showing both demand and a clear gap in current static configuration approaches.
