## [0.3.0] - 2025-05-21

### Changed

- **Migrated peer dependencies** from `@mariozechner/*` to `@earendil-works/*`
  - `@mariozechner/pi-ai` → `@earendil-works/pi-ai`

## [0.2.0] - 2025-04-12

### Changed

- **Refined `promptGuidelines` for all tools** to focus on "when to use" rather than "how to use"
  - Guidelines are now self-contained and standalone
  - Removed vague references like "This tool" in favor of explicit tool names
  - Balanced positive (when TO use) and negative (when NOT to use) guidelines

### Fixed

- **Fixed TypeScript return types** for all tool handlers to consistently include `details: {}`
- **Changed enum types** from `StringEnum` to `Type.Union`/`Type.Literal` for better schema compatibility
- **Added type annotation** in filter callback for `task_close` parent check

### Documentation

- Added prominent comment explaining how `promptGuidelines` are aggregated and displayed
- Enhanced `task_close` description to clarify `indexOrTitle` requirements
