Search the skills registry by keyword or tag.
AI agents call search_skills to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search operation against a registry. It retrieves information without creating, modifying, deleting, or executing any operations. The search function is a classic Read category operation with minimal security risk—the worst case is information disclosure of already-cataloged skills.
From the tool's definition Tool name 'search_skills' and description 'Search the skills registry by keyword or tag' indicate a query/retrieval operation with no modification or execution of code.
