+description: Maintains CHANGELOG.md in the project root using git commit history. Use when the user invokes /changelog, asks to "update the changelog", "generate a changelog", or wants to record what changed before merging a branch. Creates the file from scratch if it doesn't exist (all commits grouped by date); otherwise appends only commits newer than the last recorded date.
+---
+
+# Changelog Skill
+
+## Workflow
+
+1. Run the script from the project root:
+
+```bash
+python3 .claude/commands/scripts/changelog.py
+```
+
+2. The script handles both cases automatically:
+   - **No CHANGELOG.md**: reads full git history, writes the file with all dates
+   - **CHANGELOG.md exists**: finds the newest `## YYYY-MM-DD` heading, fetches commits after that date, prepends new sections
+
+3. Review the output, edit bullet wording if needed, then commit `CHANGELOG.md` as part of the merge commit.
+
+## Format
+
+```markdown
+# Changelog
+
+## 2026-06-17
+
+- Add responsive design to layout and CSS
+- Add Vitest test suite for components and routes
+
+## 2026-04-13
+
+- Initial project scaffold
+```
+
+- One `# Changelog` title at the top
+- Date headings as `## YYYY-MM-DD`, newest first
+- Each commit is one bullet; wording may be cleaned up manually after generation
+
+## Notes
+
+- Run from the **project root** (same directory as `.git/`)
+- Commit subjects come directly from `git log`; clean them up manually if needed
+- The script is idempotent: re-running when nothing is new prints a message and exits without modifying the file
