Operating rules

Use scripts/ncbi_pmc.py for all PMC Open Access calls in this package.
This skill is intentionally narrow: it currently covers the PMC Open Access service rather than the full PMC API surface.
Pass endpoint-specific query parameters under params, typically id for a PMCID or DOI-style lookup supported by the OA service.
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 output by default.
Return raw XML only if the user explicitly asks for machine-readable output.
Prefer targeted endpoint calls instead of broad unfiltered dumps.
If the user needs the full raw response, set save_raw=true and report the saved file path.

Read one JSON object from stdin.
Optional fields: params, record_path, max_items, max_depth, timeout_sec, save_raw, raw_output_path
Common PMC Open Access patterns:
