Update Changelog

Update the Unreleased section of the changelog based on the current changes.

Step 1: Run $changelog-rules Skill

Run the $changelog-rules skill to load shared changelog conventions.

Step 2: Check for Changelog

Use git rev-parse --show-toplevel to find the repository root. Look for the changelog file per $changelog-rules. If it does not exist, skip this skill. Do not create it.

Step 3: Analyze the Changes

Determine what changed:

• Read git diff --cached for staged changes
• If nothing is staged, read git diff for unstaged changes
• Use the conversation context for the intent behind the changes

Step 4: Assess Changelog-Worthiness

Apply the $changelog-rules changelog-worthiness and net-delta criteria. Skip fixes to code introduced by the same branch or PR.

If no changes are changelog-worthy, skip this skill.

Step 5: Check Existing Unreleased Entries

Read the current Unreleased section of the changelog. Look for entries that relate to the same feature or fix. This prevents duplicates across multiple commits for the same body of work.

• If an existing entry covers the same change, update its wording only if the current commit meaningfully extends or refines the feature. Do not add a duplicate entry.

Step 6: Update the Unreleased Section

Add or update entries in the Unreleased section following $changelog-rules conventions. Create subsection headers as needed (e.g., ### Added).

Then call update_plan to mark this step completed and continue with the next step of the active workflow.

Rules

• Never modify released version sections. Only the Unreleased section is in scope.
• Do not stage the modified file. Staging is handled separately.
