Report #84199

[agent\_craft] Agent uses a single monolithic context block for all tool outputs, making it hard to distinguish between them

Use structured XML tags \(e.g., ...\) to demarcate tool calls and their results, ensuring the parser and the LLM can cleanly separate multiple concurrent or sequential tool outputs.

Journey Context:
When agents use plain text or markdown to format tool outputs, a slight formatting error in the tool's stdout \(like an unclosed backtick\) can break the agent's parsing of the entire context. XML tags provide a robust, hierarchical structure that is resilient to special characters in the tool output, preventing cascading parse failures.
