+# Soulfield OS — Tools
+
+This folder collects **practical reference docs and scripts** for operating the Soulfield vault and Aiden’s context spine.
+
+## Contents
+- [[Aiden-Pinecone-Query-Recipes.md]] — ready-to-run Pinecone query patterns
+- (future) Command cheatsheets, automation guides, CLI usage
+
+## Notes
+- Tools are living references: they evolve with scripts (`tools/*.cjs`) and automation.
+- Each tool doc should be linked from Project Memory under “Related Tools” to keep it discoverable.
