  # Changelog writing
  
  ## When to use
  
  The user asks for a changelog, release notes, or "what shipped" summary.
  
  ## Steps
  - 1. Collect merged PR titles and descriptions for the release window.
- 2. Group by: Added, Changed, Fixed, Removed.
- 3. Rewrite each entry for end users: outcome first, no internal jargon,
-    no ticket numbers, present tense.
- 4. Flag breaking changes at the top with a migration hint.+ 1. Collect merged PR titles and descriptions for the release window. Ignore
+    internal-only chores (dependency bumps with no user effect, CI tweaks).
+ 2. Group remaining changes: Added, Changed, Fixed, Removed.
+ 3. Rewrite each bullet for an end user: outcome first, present tense, no ticket
+    numbers, no jargon that is not already in the product UI.
+ 4. Put breaking changes at the top with a one-line migration hint.  - ## Output format+ ## Output  - Markdown with a version heading, grouped sections, one bullet per change.+ ```markdown
+ ## vX.Y.Z — YYYY-MM-DD
+ 
+ ### Breaking
+ - …
+ 
+ ### Added
+ - …
+ 
+ ### Changed
+ - …
+ 
+ ### Fixed
+ - …
+ ```
+ 
+ If a section is empty, omit it. Prefer 5–12 bullets over a wall of text.
