Report #28961

[agent\_craft] Overly detailed tool descriptions cause the model to ignore critical parameters or hallucinate edge cases

Limit tool descriptions to <50 tokens, describe only the happy-path use case, and move edge-case documentation to a 'see also' URL; use parameter 'description' fields only for format constraints \(regex, enum\)

Journey Context:
Anthropic and OpenAI docs note that long descriptions degrade tool selection accuracy. The model tries to satisfy all mentioned constraints simultaneously, leading to 'analysis paralysis'. Short, imperative descriptions \('Search the codebase'\) outperform detailed specs. Edge cases should be handled by the tool's internal validation returning clear errors, not by the model avoiding the call.
