Operating rules

• Use scripts/clinicaltrials_client.py for all ClinicalTrials.gov v2 calls.
• Study searches are better with max_items=10 and max_pages=1; only increase pages when the user explicitly wants more than the first page.
• Use targeted params instead of broad unfiltered study dumps.
• Re-run requests in long conversations instead of relying on older tool output.
• Treat displayed ... in tool previews as UI truncation, not literal request content.

Execution behavior

• Return concise markdown summaries from the script JSON by default.
• Prefer action=studies for search and action=metadata|search_areas|enums|stats_size|field_values|field_sizes for API introspection and field stats.
• If the user needs full pages or aggregated responses, set save_raw=true and report the saved file path.

Input

• Read one JSON object from stdin.
• Required field: action
• Supported actions: studies, metadata, search_areas, enums, stats_size, field_values, field_sizes, request
• Optional fields: path for action=request, params, max_items, max_depth, max_pages, timeout_sec, save_raw, raw_output_path
• Common ClinicalTrials.gov patterns:
  • {"action":"studies","params":{"query.cond":"prostate cancer","filter.overallStatus":"RECRUITING","pageSize":10},"max_items":10,"max_pages":1}
  • {"action":"metadata"}
  • {"action":"field_values","params":{"field":"protocolSection.identificationModule.organization.fullName"}}

Output

• action=studies returns pages_fetched, next_page_token, count metadata, and compact records.
• Other actions return either compact records or a compact summary.
• Use raw_output_path when save_raw=true.
• Failure returns ok=false with error.code and error.message.

Execution

echo '{"action":"studies","params":{"query.cond":"prostate cancer","filter.overallStatus":"RECRUITING","pageSize":10},"max_items":10,"max_pages":1}' | python scripts/clinicaltrials_client.py
