+# Collaboration Directory
+
+This directory is reserved for project-specific collaboration and should remain at the top level of the repository. It will not be mounted into AI home directory containers as it's intended to be project-specific.
+
+## Purpose
+
+- Project-specific collaboration files
+- Project-specific rules and guidelines
+- Temporary collaboration artifacts
+- Project-specific environment configurations
+
+## Structure
+
+```
+collab/
+├── rules/          # Project-specific rules (SECURITY.md, RELEASE.md, etc.)
+├── env/            # Project-specific environment configurations
+├── proposals/      # Project-specific proposals and planning
+└── temporary/      # Temporary collaboration files
+```
+
+This directory serves as a bridge between the universal AI home directory (databank) and project-specific needs. Each project using this AI home directory will have its own collab directory.
