+description: mtm-ddwipe project conventions
+---
+
+# Project conventions
+- Use English throughout the project.
+- Keep shell scripts Bash-based when Bash is already used by the project.
+- Preserve the current behavior of the main script:
+  - `mtm-ddwipe`: wipe devices.
+- Keep user-facing messages short, clear, and in English.
+- Prefer minimal, focused changes that do not alter the intent of the existing scripts, unless the script behavior is intentionally updated.
+- Maintain `.continue/rules/project.md` whenever project conventions or script behavior change.
+- `mtm-ddwipe` is a small Bash script with helper functions.
+- Keep the host and line-number removal behavior intact.
+- `mtm-ddwipe` must print a usage line and support `-h`/`--help`.
+
+# Project identity
+- Main script: `mtm-ddwipe`

+Usage:
+  makerelease.sh VERSION
+  makerelease.sh +0.0.1
+  makerelease.sh +0.1
+  makerelease.sh +1
+  makerelease.sh --dry-run VERSION
+  makerelease.sh --dry-run +0.0.1
+  makerelease.sh --dry-run +0.1
+  makerelease.sh --dry-run +1
+
+Creates an annotated Git tag from the current dev branch.
+
+If VERSION starts with +, it is treated as an increment:
+- +0.0.1 increments patch
+- +0.1 increments minor
+- +1 increments major
+
+Use --dry-run to show the computed release version without running Git actions.
+
+Requirements:
+- run from a clean Git working tree
+- current branch must be dev for real releases
+- main branch must exist locally
