Structured Data Extraction

A structured data extraction pipeline uses server-side web_search tools to enrich contract records with public company data before writing to a database. For contracts tied to large enterprise clients, the enrichment workflow involves many sequential lookups. After deploying to production, engineers observe that roughly 15% of enrichment jobs terminate early — the pipeline logs show these jobs receive a pause_turn stop reason, and the partially-enriched records are written to the database with missing fields. What is the most likely root cause, and what structural fix addresses it?

A. The server tools are timing out due to network latency. Add retry logic with exponential backoff around each individual web_search call to prevent early termination and ensure all enrichment lookups complete successfully.

B. The sampling loop is hitting the 10-iteration limit before completing all lookups. Detect pause_turn, append the assistant's response to the message history, and issue a continuation request — gating the database write until a non-pause_turn stop reason is received.

C. The max_tokens budget is being exhausted mid-enrichment. Increase max_tokens so Claude has sufficient room to complete the full sequence of lookups in a single response, preventing truncation before all fields are populated.

D. Claude is silently dropping tool calls because the tool description is too vague. Rewrite the web_search tool description to explicitly enumerate each field the pipeline expects to extract, ensuring all required lookups are attempted before the response is returned.
