+# VideoTools Agent Workflow Rules
+
+These rules apply to any automation or agent working in this repo.
+
+## Commit Discipline
+
+- After every change: `git add` then `git commit -m "..."`.
+- Do not leave unstaged changes in the worktree.
+- Commit only files related to the current task.
+
+## Documentation Discipline
+
+- If behavior changes, update:
+  - `docs/INSTALLATION.md`
+  - the relevant platform guide (`docs/INSTALL_WINDOWS.md`, `docs/INSTALL_LINUX.md`)
+- Always update `DONE.md` and `TODO.md` for completed or planned work.
+- Avoid personal names in documentation; use `user report` or `dev report` only.
+
+## Windows Install Flow
+
+- Use `scripts\install.ps1` or `scripts\install.bat` from PowerShell/CMD.
+- `scripts/install.sh` is for bash shells only; do not run it from PowerShell.
+
+## Coordination
+
+- Ask before changing workflow entrypoints or automation behavior.
+- If a change affects installs/builds, add a short note in docs.
