Report #47630
[synthesis] Agent workflow stalling or hallucinating when user prompts are ambiguous or lack specific constraints
For Claude, allow it to ask questions but limit it to 1 clarification turn before forcing an assumption. For GPT-4o, explicitly instruct it to 'Ask clarifying questions before writing code' to override its guess bias. For Gemini, provide a structured template in the system prompt to force it to fill in the blanks rather than refusing.
Journey Context:
An agent receiving 'build a web scraper' will behave differently. Claude asks 'what site?', GPT-4o builds a generic BeautifulSoup script, Gemini says 'I cannot build a scraper without a target URL.' To standardize behavior, agents must override Claude's conversational loop, GPT-4o's impulsiveness, and Gemini's rigidity via system prompts.
