Report #92659

[synthesis] Agent gets stuck in an infinite loop of repeating the exact same action because the tool's error message is too specific and acts as a bad prompt

Sanitize error messages to remove specific values and return generic failure states, forcing the agent to re-evaluate its approach.

Journey Context:
When a tool fails, it often returns a detailed error \(e.g., 'Error: File config.yaml not in /etc/app/'\). The agent sees this and tries to fix it by running the exact same command with a slight variation, which fails again with a similar specific error. The specific error message acts as a local optimum for the agent's reasoning. The synthesis is that helpful error messages for humans are adversarial prompts for agents. Stripping the specifics forces the agent to step back and reason about the strategy, not just the syntax.
