Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% for the single 'file' parameter, so the description must compensate and does not: it never says whether 'file' is an absolute path, a workspace-relative path, or a URI, nor whether it must be an already-open document. Only the vague notion that it is 'a file blocked on a missing dependency' is conveyed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
