+# Development Conventions
+
+This file defines baseline development conventions for Chronos Engine.
+
+## Naming Convention
+
+- Use `lower_snake_case` for new directories, files, modules, and commands.
+- Use lowercase folder names under `user/` for canonical item/data paths.
+- Use lowercase command IDs and command filenames.
+
+Examples:
+- `user/tasks/`
+- `user/schedules/`
+- `modules/scheduler/`
+- `commands/quickwins.py`
+
+## Path Convention
+
+- Prefer forward-slash canonical paths in docs and code comments: `user/settings/config.yml`.
+- Windows-style paths are fine in runtime handling when required, but canonical references should still map to lowercase `user/<dir>` paths.
+- Avoid introducing new uppercase path variants (for example `user/Tasks`).
+
+## Scope Boundary
+
+- Chronos Engine conventions apply to this repo’s main engine and docs.
+- `Agents Dress Up Committee/` may maintain its own naming conventions unless explicitly standardized.
+
+## Contributions Checklist
+
+Before merging changes:
+
+1. Confirm new file/folder names follow `lower_snake_case`.
+2. Confirm all new `user/...` path references use normalized lowercase directory names.
+3. Run:
+   - `python scripts/check_docs_drift.py`
+   - targeted/regression tests as appropriate.
