Report #73970
[synthesis] Redundant verification tool calls after executing a write operation
Include 'The file has been updated successfully. Do not read the file again to verify.' in the tool result string to prevent wasted tokens and latency.
Journey Context:
After successfully writing a file via a tool call, Claude 3.5 Sonnet exhibits a behavioral fingerprint of immediately calling a read tool on the same file to verify the write, consuming extra tokens and latency. GPT-4o generally trusts the tool output and proceeds to the next step. To optimize Claude's agentic loops, the tool result must explicitly confirm success and forbid re-reading, standardizing the behavior across models.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
