+# Loading one skill: two model calls
+
+model calls: 2
+first call mentions the skill body ('Breaking' in any message)  : false
+
+--- tool result fed back to the model (what the Skill tool returned) ---
+Base directory for this skill: <module>/target/classes/skills/release-notes
+
+# Release notes
+
+Turn a list of merged changes into release notes a user can act on.
+
+1. Group the changes under **Breaking**, **Added**, **Fixed** and **Internal**, in that order.
+2. Lead every **Breaking** item with what the reader must change, not with what the team did.
+3. Read `references/style-guide.md` (in this skill's directory) before writing the final text.
+4. Never invent a ticket number. If a change has none, leave the reference out.
+
+Return the notes as Markdown with one bullet per change.
+
+--- final answer ---
+## Breaking
+- Rename `cache.ttl` to `cache.expiry`.
