+## Instructions
+
+Commit current changes, create the next version tag, and push everything to remote.
+
+### Step 1 — Commit
+
+Use the `/commit` skill to stage and commit changes. Pass along any user arguments as the commit message.
+
+```
+/commit $ARGUMENTS
+```
+
+### Step 2 — Tag
+
+Get the latest tag and increment the patch number (e.g., `0.9.27` → `0.9.28`). Create the tag:
+
+```bash
+git tag --sort=-v:refname | head -1
+```
+
+```bash
+git tag <next-version>
+```
+
+### Step 3 — Push
+
+Push the commit and tag to remote:
+
+```bash
+git push && git push --tags
+```
+
+### Step 4 — Verify
+
+Confirm the tag exists on the pushed commit:
+
+```bash
+git log --oneline -1 --decorate
+```
+
+## User arguments
+
+```text
+$ARGUMENTS
+```
+
+If the user provided arguments, treat them as the commit message or guidance for what to commit.
