+
+### 🔧 Package Configuration Improvement
+
+This **patch release** improves the packaging configuration by switching from manual package listing to automatic package discovery, preventing similar issues in the future.
+
+### Changed
+
+- **Package Discovery**: Switched from manual package listing to automatic discovery in pyproject.toml ([#227](https://github.com/yusufkaraaslan/Skill_Seekers/pull/227))
+  - **Before**: Manually listed 5 packages (error-prone when adding new modules)
+  - **After**: Automatic discovery using `[tool.setuptools.packages.find]`
+  - **Benefits**: Future-proof, prevents missing module bugs, follows Python packaging best practices
+  - **Impact**: No functional changes, same packages included
+  - **Credit**: Thanks to [@iamKhan79690](https://github.com/iamKhan79690) for the improvement!

+- ✅ `skill_seekers` (core)
+- ✅ `skill_seekers.cli` (CLI tools)
+- ✅ `skill_seekers.cli.adaptors` (platform adaptors)
+- ✅ `skill_seekers.mcp` (MCP server)
+- ✅ `skill_seekers.mcp.tools` (MCP tools)
+
