 <command-instruction>
-Analyze the unpublished changes since the last npm release and provide a structured summary.
+IMMEDIATELY output the analysis. NO questions. NO preamble.
 
-Your task:
-1. Review the context below (auto-injected via shell)
-2. Summarize changes grouped by type (feat, fix, refactor, docs, chore)
-3. Highlight breaking changes if any
-4. Suggest next version bump (major/minor/patch) based on conventional commits
+## CRITICAL: DO NOT just copy commit messages!
+
+For each commit, you MUST:
+1. Read the actual diff to understand WHAT CHANGED
+2. Describe the REAL change in plain language
+3. Explain WHY it matters (if not obvious)
+
+## Steps:
+1. Run `git diff v{published-version}..HEAD` to see actual changes
+2. Group by type (feat/fix/refactor/docs) with REAL descriptions
+3. Note breaking changes if any
+4. Recommend version bump (major/minor/patch)
+
+## Output Format:
+- feat: "Added X that does Y" (not just "add X feature")
+- fix: "Fixed bug where X happened, now Y" (not just "fix X bug")
+- refactor: "Changed X from A to B, now supports C" (not just "rename X")
