List all stub notes (placeholders) in a vault that need expansion. Use this tool to: 1. Find stubs that need content 2. Prioritize which stubs to expand first 3. See which notes mention each stub Stubs are created automatically when content contains [[wiki-links]] to non-existent notes.
AI agents call palace_stubs to retrieve information from Obsidian Palace MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only queries to identify placeholder notes in a vault. It retrieves information about stub notes and their mentions but does not modify, delete, or execute any operations. The three use cases (find stubs, prioritize, see mentions) are all informational queries with no side effects. No data is created, modified, or destroyed.
From the tool's definition Tool name 'palace_stubs' and description state it 'List all stub notes' and 'Find stubs that need content' — purely retrieval operations with no mutation, deletion, or execution of code.
