September 2025 performance highlights for CherryHQ/cherry-studio: - Delivered the cornerstone AgentService framework with full CRUD operations, session management, and structured logging, backed by Drizzle ORM across agents, sessions, and session messages. APIs initialized in ApiServer with ID generation improvements and modular architecture. - Implemented a robust REST API for agents, sessions, and logs with type support, validation (express-validator), OpenAPI docs, and PUT/PATCH endpoints to support full lifecycle management. - Enabled automatic database schema synchronization via Drizzle ORM, reducing manual migrations, improving deployment reliability, and ensuring schema consistency on startup. - Modernized Claude Code integration by migrating from Claude Code SDK to Claude Agent SDK v0.1.1, adding OAuth support, streaming, tool integration, and improved error handling; enhanced packaging and runtime reliability. - Expanded tooling and session configuration with allowed tools, MCP server support for agents, advanced configuration settings, and improved agent tool approval UI; introduced caching for MCP servers/providers to boost performance. - Strengthened quality and internationalization with i18n translations across languages, documentation improvements (CLAUDE.md, UI integration guides), and comprehensive HTTP tests for agents and sessions. Business value and impact: - Accelerated agent onboarding and autonomous management, reducing manual operational work by automating schema evolution and lifecycle operations. - Increased system reliability and performance through caching, robust validation, and structured error handling, enabling safer deployments and faster iteration. - Enhanced user experience with tool selection, translations, and richer session context in the UI, supporting global teams and multi-language usage.
