Full-text search across all Playbook wiki pages.
AI agents call playbook_search to retrieve information from Quarterback without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs information retrieval (full-text search) without creating, modifying, deleting, or executing operations. It has read-only semantics and minimal blast radius if misused by an AI agent, as search queries cannot cause side effects beyond retrieving existing data. Classified as Read with low severity.
From the tool's definition Tool description states 'Full-text search across all Playbook wiki pages' — this is a search/query operation with no modification capability.
