Report #86040

[synthesis] Agent loops or selects wrong tool when multiple tools have overlapping functionality

Disambiguate tool names and descriptions aggressively. If using Claude, expect it to ask the user for clarification; ensure your loop allows text responses. If using GPT-4o, it will guess; add disambiguating keywords to tool descriptions to guide the guess.

Journey Context:
When faced with \`search\_files\` vs \`search\_code\`, Claude 3.5 Sonnet often stalls and asks the user 'Which one?'. GPT-4o tends to pick one based on subtle description cues or order. This means Claude agents feel slower but are safer, while GPT agents are faster but prone to silent misrouting.
