+# Plan Feature: $1
+
+Use the roadmap-planning, issue-writing, and forgejo skills.
+
+1. **Understand the feature**: Analyze what "$1" involves
+2. **Explore the codebase** if needed to understand context
+3. **Break down** into discrete, actionable issues:
+   - Each issue should be independently completable
+   - Clear dependencies between issues
+   - Appropriate scope (not too big, not too small)
+
+4. **Present the plan**:
+   ```
+   ## Proposed Issues for: $1
+
+   1. [Title] - Brief description
+      Dependencies: none
+
+   2. [Title] - Brief description
+      Dependencies: #1
+
+   3. [Title] - Brief description
+      Dependencies: #1, #2
+   ```
+
+5. **Ask for approval** before creating issues
+6. **Create issues** in order using `fj issue create`
+7. **Update dependencies** with actual issue numbers after creation
+8. **Present summary** with links to created issues
