+## [0.3.4] - 2026-01-30
+
+### Documentation
+
+- **Address 20 documentation gaps from claude-docs audit** - Comprehensive audit against official Claude Code documentation identified missing topics relevant to plugin developers. Added 5 new reference files covering:
+  - Advanced frontmatter fields (model, scoped hooks, visibility budget)
+  - Headless/CI mode compatibility
+  - GitHub Actions integration
+  - Memory & rules system interaction
+  - Advanced topics (keybindings, status line, caching, CLI commands, installation scopes)
+- **Enhanced skill coverage** - Updated 6 skills (skill-development, hook-development, agent-development, mcp-integration, plugin-structure, plugin-settings) with inline additions and trigger phrases for new content
+- **Added cross-cutting references** - New reference docs address plugin behavior in non-interactive contexts (headless mode, GitHub Actions, CI pipelines)
