## [Unreleased] |

|
| 10 |
## [0.1.3] - 2026-08-10 |
| 11 |
|
| 12 |
### Fixed |
| 13 |
|
| 14 |
- Open MCP schema types now preserve unrecognized fields during `fromArray()` and `toArray()` round trips, including additional JSON Schema keywords such as `$defs` in tool input and output schemas. |
| 15 |
|
| 16 |
## [0.1.2] - 2026-06-05 |
| 17 |
|
| 18 |
### Fixed |
| 19 |
|
| 20 |
- `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. |

## [0.1.1] - 2026-04-10 |
| 23 |
|
| 24 |
### Fixed |
| 25 |
|
| 26 |
- 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. |
| 27 |
- Exclude `CLAUDE.md` from Composer dist archives. It contains dev-only project instructions with no runtime purpose for package consumers. |
