+tags: ['library', 'query', 'search']

+
+# Library Query
+
+## Purpose
+Find relevant patterns from the self-learning library before starting work, to avoid reinventing solutions and to apply known best practices.
+
+## When to Use
+- At the start of any new project or task
+- When designing architecture for a new feature
+- When debugging an error (find prior solutions)
+- When planning a phase
+
+## When Not to Use
+- For trivial questions (just ask)
+- For project-specific state (read the project files)
+
+## Procedure
+1. Formulate query keywords: technology, problem type, domain, project type
+2. Call the library-query API:
+```
+GET /api/plugins/a0_software_orchestrator/library_search?q=<keywords>
+```
+3. Review top results by relevance
+4. For each relevant pattern, read the full content via:
+```
+GET /api/plugins/a0_software_orchestrator/library_get?id=<pattern_id>
+```
+5. Apply the pattern to the current work, citing the pattern_id
