[agent\_craft] Injecting hundreds of tool schemas into the system prompt consuming 50%\+ of the context window

Implement a tool router or dynamic tool loading system that only injects schemas relevant to the current sub-task.

Journey Context:
Every tool definition consumes tokens. If an agent has access to 100 tools \(e.g., various API endpoints, shell commands\), the schemas alone can take up 10k\+ tokens. This leaves less room for conversation and context. By using a retriever to select only the top-k relevant tools based on the user's query, or by phasing tools \(e.g., exploration tools vs editing tools\), you preserve the context budget for actual task data.
