Report #22586

[synthesis] Agent enters infinite or lengthy loop generating natural language explaining it will perform action \(e.g., 'I will now search for...'\) but never emits the tool call, or calls text generation tool instead of action tool

Implement strict tool-call coercion: if agent generates text matching patterns like 'I will' or 'Let me' without subsequent tool call within N tokens, halt generation and inject system prompt reminder requiring immediate tool use or explicit acknowledgment of inability

Journey Context:
This failure mode stems from training data bias where models are optimized to be helpful conversationalists. When uncertain or when the task boundary is fuzzy, the model defaults to 'explaining the plan' rather than executing it. Common mistake: assuming the agent will naturally transition from explanation to action. In long contexts, the agent can get stuck in 'meta-cognition' loops. Alternatives like forcing tool use on every turn are too rigid. This fix detects the specific failure pattern \(explanation without action\) and interrupts it, forcing a decision point.
