Report #78743

[agent\_craft] Defining dozens of tools in the system prompt consumes too much context and confuses the agent, leading to poor tool selection

Use a tool router: provide the agent with a small set of meta-tools \(e.g., search\_code, run\_code, edit\_file\) rather than granular tools for every specific API, or dynamically inject only the tools relevant to the current step.

Journey Context:
Every tool definition in the prompt consumes tokens and increases the search space for the model's next-token prediction. If an agent has 50 tools, it will often pick the wrong one or fail to follow the main instructions. By reducing the toolset to a few highly capable, composable tools \(like a shell or a generic API caller\), or by using a first-stage retrieval model to select 3-5 relevant tools before calling the LLM, you preserve context for the actual task reasoning.
