 ## [Unreleased]
 
+### Added
+
+- **SDK for programmatic usage**: New `createAgentSession()` factory with full control over model, tools, hooks, skills, session persistence, and settings. Philosophy: "omit to discover, provide to override". Includes 12 examples and comprehensive documentation. ([#272](https://github.com/badlogic/pi-mono/issues/272))
+
+- **Project-specific settings**: Settings now load from both `~/.pi/agent/settings.json` (global) and `<cwd>/.pi/settings.json` (project). Project settings override global with deep merge for nested objects. Project settings are read-only (for version control). ([#276](https://github.com/badlogic/pi-mono/pull/276))
+
+- **SettingsManager static factories**: `SettingsManager.create(cwd?, agentDir?)` for file-based settings, `SettingsManager.inMemory(settings?)` for testing. Added `applyOverrides()` for programmatic overrides.
+
+- **SessionManager static factories**: `SessionManager.create()`, `SessionManager.open()`, `SessionManager.continueRecent()`, `SessionManager.inMemory()`, `SessionManager.list()` for flexible session management.
