Report #7200

[agent\_craft] Agent system prompt degrades in instruction-following due to injecting dozens of unused tool schemas

Implement a tool router. Inject only a core set of essential tools \(e.g., file read/write, shell\) into the primary context. Add a search\_tools or delegate\_to\_subagent capability that loads specialized tool schemas \(e.g., database queries, cloud deployments\) only when the task requires them.

Journey Context:
Every tool definition consumes tokens and adds to the attention burden. A 50-tool OpenAPI spec can consume 10k\+ tokens, drastically reducing the space for actual reasoning and increasing the chance of picking the wrong tool. The router/subagent pattern adds a latency overhead \(an extra LLM call to route\), but keeps the primary context lean and focused, significantly improving tool selection accuracy.
