Operating rules

Use scripts/rest_request.py for all OLS4 and EFO API calls.
Use base_url=https://www.ebi.ac.uk/ols4/api.
Search, children, and descendant endpoints are better with max_items=10; single term lookups usually do not need max_items.
Use the smallest ontology expansion that answers the question.
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 these paths: search, ontologies/efo/terms/<double-encoded-iri>, and the corresponding children or descendants paths.
If the user needs the full payload, set save_raw=true and report the saved file path.
