## [0.1.2] - 2026-06-05 |

### Fixed |
| 13 |
|
| 14 |
- `ToolInputSchema::toArray()` and `ToolOutputSchema::toArray()` now always emit the `properties` key as a JSON object, even for tools that declare no parameters. Parameter-less tools previously produced `{"type":"object"}` (key omitted) or `[]` (JSON array), both of which strict JSON Schema validators such as OpenAI strict function-calling mode reject with `object schema missing properties`. Tools with parameters are unchanged. The fix is mirrored in the TypeScript generator so a clean regeneration reproduces the patched output. |

### Fixed |

- Exclude `skill/` directory from Composer dist archives. It contains dev-only helper scripts and reference docs that have no runtime purpose for package consumers and should not ship in the `vendor/` folder. |
| 21 |
- Exclude `CLAUDE.md` from Composer dist archives. It contains dev-only project instructions with no runtime purpose for package consumers. |
