+## [0.22.5] - 2025-12-02 - Commands Configuration
+
+### Added
+
+- **CommandsConfigSchema (0.22.5)**

+  - Exported `CommandsConfig` type from config module
+
+### Changed
+
+- **RunCommandTool**
+  - Added optional `config?: CommandsConfig` parameter to constructor
+  - Timeout priority: `params.timeout` → `config.timeout` → `DEFAULT_TIMEOUT (30000)`
+  - Updated parameter description to reflect configuration support
+  - Config-based timeout enables global command timeout without per-call specification
+
+### Technical Details
+

+- New test file: `commands-config.test.ts` with 19 tests
+  - Default values validation (timeout: null)
+  - `timeout` nullable positive integer validation (including edge cases: zero, negative, float rejection)
+  - Partial and full config merging tests
+- Updated RunCommandTool tests: 3 new tests for configuration integration
+  - Config timeout behavior
+  - Null config timeout fallback to default
+  - Param timeout priority over config timeout
+- Coverage: 97.64% lines, 91.36% branches, 98.77% functions, 97.64% statements
