name	changelog
description	Generate and update the product changelog in Mintlify docs. Use when the user asks to update the changelog, add a changelog entry, document recent changes, or write release notes. Reads git history on main, filters to user-facing changes, and writes dated MDX files to docs/changelog/.

Changelog

Generate user-facing changelog entries from git history and write them as Mintlify MDX files.

• references/guide.md — writing conventions, title rules, and anti-patterns
• references/format.md — MDX template and formatting rules

Workflow

1. Read watermark

Read .claude/skills/changelog/watermark for the last processed commit SHA. If the file is missing (first run), use the commit from 30 days ago as the starting point: git log --before="30 days ago" --format=%H -1 main.

2. Gather changes

Run git log --oneline --no-merges <watermark>..HEAD to get commits since the watermark. Read commit messages and changed files to understand the actual user-facing impact — don't just reword commit messages.

3. Filter and group by date

Group commits by their commit date (git log --format="%h %ad %s" --date=short). Each date that has user-facing changes gets its own entry file. Dates with only internal changes get no entry.

Include only changes visible to end users:

• New features and capabilities
• Bug fixes that affected users
• Breaking changes or behavioral changes
• New integrations or provider support
• Performance improvements users would notice
• UI/UX changes

Exclude:

• Internal refactors with no behavior change
• Test-only changes
• CI/CD pipeline changes
• Dependency bumps (unless they fix a user-facing issue)
• Code style or linting changes

If there are no user-facing changes in the entire range, tell the user and stop.

4. Write changelog entries

Create one file per date at docs/changelog/YYYY-MM-DD.mdx, using the commit date (not today's date). If a file already exists for a date, regenerate it with the full set of commits for that day (not just new ones). Follow the references linked above for format, writing style, and hero vs. accordion decisions.

• Batch related commits into a single feature section (e.g., multiple hook-related commits become one "Lifecycle hooks" section)

5. Update docs/docs.json

Add all new pages to the Changelog tab's pages array in docs/docs.json. List entries most recent first. The page path is changelog/YYYY-MM-DD (no .mdx extension).

6. Write watermark

Write the output of git rev-parse HEAD to .claude/skills/changelog/watermark.

7. Clean up legacy single-file changelog

If docs/changelog.mdx still exists as the old single-file changelog, delete it and remove its reference from docs/docs.json.
