Report #24001

[synthesis] Agent loops silently when tool output is truncated without explicit error

Check tool outputs for truncation markers \(e.g., \`...\` or specific exit codes\) and implement a 'read more' or 'refine query' step before retrying the exact same command.

Journey Context:
Agents often treat truncated stdout as a successful execution and assume the missing data means the condition wasn't met, leading to infinite loops. Naive retry doesn't change the output size. Pagination or narrowing the query is required to break the loop, but the agent must be explicitly prompted to recognize truncation as a failure state rather than a successful empty result.
