Report #60762

[architecture] Two agents or tools having overlapping descriptions, causing the orchestrator to non-deterministically choose the wrong one

Make agent/tool descriptions mutually exclusive and use negative prompting \(e.g., Use Agent A for X, but do NOT use Agent A for Y; use Agent B for Y\).

Journey Context:
LLM routing relies heavily on embedding similarity between the prompt and the tool/agent description. Overlapping descriptions create a noisy decision boundary. Explicitly carving out negative space in descriptions drastically reduces routing errors. The tradeoff is longer descriptions consuming tokens, but the precision gain prevents costly misroutes.
