Functions exposed to the LLM to take actions

Name	Description
list_coverages	Lists all available datacubes (coverages) in rasdaman.
describe_coverage	Retrieves structural metadata for a specific datacube (coverage).
wcps_query_crash_course	Returns a crash course on writing WCPS queries: learn the basic syntax, common operations, and best practices for WCPS queries. It's recommended to check this before executing queries.
execute_wcps_query	Executes a Web Coverage Processing Service (WCPS) query in rasdaman. Use this for spatio-temporal subsetting of datacubes, processing, aggregation, filtering. Returns a structured dictionary indicating success, result_type, original query, the actual result value for scalar and small JSON or file path for large/binary results. Important: Show the actual WCPS query and the result file path to the user.
wcps_doc_chaptersA	Lists the detailed WCPS documentation chapters, one per topic, each with a description of what it covers and when to fetch it. Use when the crash course is not detailed enough — pick the chapter matching your problem and fetch it with wcps_get_chapter(name). After a failed query, the 'common-errors' chapter maps error symptoms to fixes.
wcps_get_chapter	Returns one full WCPS documentation chapter (markdown) by name, as listed by wcps_doc_chapters(). Example: wcps_get_chapter("switch-case").
