Search the user’s skills by name. Skills are markdown documents containing instructions for AI to read and follow; when the user references a skill (or a request matches one), find it with this tool and then read its instructions with ReadContent using the returned document id. This is keyword search against skill names: pass 1-3 targeted keywords that would literally appear in the skill’s name, not a natural-language description. Matching defaults to prefix; set matchType to ‘exact’ for whole-token matching. Only skills the user can access are returned, most recently updated first.
