+Overview
+
+Implement comprehensive CRUD APIs for agent, agentSession, and agentSessionLogs management
+in Cherry Studio's API server using RESTful URL conventions.
+
+Architecture Overview
+
+1. Service Layer
+
+- Create AgentService class in src/main/services/agents/AgentService.ts
+  - Handles database operations using SQL queries from db.ts
+  - Manages SQLite database initialization and connections
+  - Provides business logic for agent operations
+
+2. API Routes
+
+- Create route files in src/main/apiServer/routes/:
+  - agents.ts - Agent CRUD endpoints
+  - sessions.ts - Session CRUD endpoints
+  - session-logs.ts - Session logs CRUD endpoints
+
+3. Database Integration
+
+- Use SQLite with @libsql/client (following MemoryService pattern)
+- Database location: userData/agents.db
+- Leverage existing SQL queries in src/main/services/agents/db.ts
+
+Implementation Steps
+
+Phase 1: Database Service Setup
+
+1. Create AgentService class with database initialization
+2. Implement database connection management
+3. Add database initialization to main process startup
+4. Create helper methods for JSON field serialization/deserialization
+
+Phase 2: Agent CRUD Operations
+
+1. Implement service methods:
+  - createAgent(agent: Omit<AgentEntity, 'id' | 'created_at' | 'updated_at'>)
+  - getAgent(id: string)
+  - listAgents(options?: { limit?: number, offset?: number })
+  - updateAgent(id: string, updates: Partial<AgentEntity>)
+  - deleteAgent(id: string)
+2. Create API routes:
+  - POST /v1/agents - Create agent
+  - GET /v1/agents - List all agents
+  - GET /v1/agents/:agentId - Get agent by ID
+  - PUT /v1/agents/:agentId - Update agent
+  - DELETE /v1/agents/:agentId - Delete agent
+
+Phase 3: Session CRUD Operations
+
+1. Implement service methods:
+  - createSession(session: Omit<AgentSessionEntity, 'id' | 'created_at' | 'updated_at'>)
+  - getSession(id: string)
+  - listSessions(agentId?: string, options?: { status?: SessionStatus, limit?: number,
+offset?: number })
+  - updateSession(id: string, updates: Partial<AgentSessionEntity>)
+  - updateSessionStatus(id: string, status: SessionStatus)
+  - deleteSession(id: string)
+  - getSessionWithAgent(id: string) - Get session with merged agent configuration
+2. Create API routes (RESTful nested resources):
+  - POST /v1/agents/:agentId/sessions - Create session for specific agent
+  - GET /v1/agents/:agentId/sessions - List sessions for specific agent
+  - GET /v1/agents/:agentId/sessions/:sessionId - Get specific session
+  - PUT /v1/agents/:agentId/sessions/:sessionId - Update session
+  - PATCH /v1/agents/:agentId/sessions/:sessionId/status - Update session status
+  - DELETE /v1/agents/:agentId/sessions/:sessionId - Delete session
+
+Additional convenience endpoints:
+  - GET /v1/sessions - List all sessions (across all agents)
+  - GET /v1/sessions/:sessionId - Get session by ID (without agent context)
+
+Phase 4: Session Logs CRUD Operations
+
+1. Implement service methods:
+  - createSessionLog(log: Omit<SessionLogEntity, 'id' | 'created_at' | 'updated_at'>)
+  - getSessionLog(id: number)
+  - listSessionLogs(sessionId: string, options?: { limit?: number, offset?: number })
+  - updateSessionLog(id: number, updates: { content?: any, metadata?: any })
+  - deleteSessionLog(id: number)
+  - getSessionLogTree(sessionId: string) - Get logs with parent-child relationships
+  - bulkCreateSessionLogs(logs: Array<...>) - Batch insert logs
+2. Create API routes (RESTful nested resources):
+  - POST /v1/agents/:agentId/sessions/:sessionId/logs - Create log entry
+  - GET /v1/agents/:agentId/sessions/:sessionId/logs - List logs for session
+  - GET /v1/agents/:agentId/sessions/:sessionId/logs/:logId - Get specific log
+  - PUT /v1/agents/:agentId/sessions/:sessionId/logs/:logId - Update log
+  - DELETE /v1/agents/:agentId/sessions/:sessionId/logs/:logId - Delete log
+  - POST /v1/agents/:agentId/sessions/:sessionId/logs/bulk - Bulk create logs
+
+Additional convenience endpoints:
+  - GET /v1/sessions/:sessionId/logs - Get logs without agent context
+  - GET /v1/session-logs/:logId - Get specific log by ID
+
+Phase 5: Route Organization
+
+1. Mount routes with proper nesting:
+// In app.ts
+apiRouter.use('/agents', agentsRoutes)
+// agentsRoutes will handle:
+// - /agents/*
+// - /agents/:agentId/sessions/*
+// - /agents/:agentId/sessions/:sessionId/logs/*
+
+// Convenience routes
+apiRouter.use('/sessions', sessionsRoutes)
+apiRouter.use('/session-logs', sessionLogsRoutes)
+
+2. Use Express Router mergeParams for nested routes:
+// In agents.ts
+const sessionsRouter = express.Router({ mergeParams: true })
+router.use('/:agentId/sessions', sessionsRouter)
+
+Phase 6: OpenAPI Documentation
+
+1. Add Swagger schemas for new entities:
+  - AgentEntity schema
+  - AgentSessionEntity schema
+  - SessionLogEntity schema
+  - Request/Response schemas
+2. Document all new endpoints with:
+  - Clear path parameters (agentId, sessionId, logId)
+  - Request body schemas
+  - Response examples
+  - Error responses
+  - Proper grouping by resource
+
+Phase 7: Validation & Error Handling
+
+1. Add path parameter validation:
+  - Validate agentId exists before processing session requests
+  - Validate sessionId belongs to agentId
+  - Validate logId belongs to sessionId
+2. Implement middleware for:
+  - Request validation using express-validator
+  - Resource existence checks
+  - Permission validation (future consideration)
+  - Transaction support for complex operations
+
+Phase 8: Testing
+
+1. Unit tests for service methods
+2. Integration tests for API endpoints
+3. Test nested resource validation
+4. Test cascading deletes
+5. Test transaction rollbacks

+
+Key Considerations
+
+- Follow RESTful URL conventions with proper resource nesting
+- Validate parent-child relationships in nested routes
+- Use Express Router with mergeParams for nested routing
+- Implement proper cascading deletes
+- Add transaction support for data consistency
+- Follow existing patterns from MemoryService
+- Ensure backward compatibility
+- Add rate limiting for write operations
+
+Dependencies
+
+- @libsql/client - SQLite database client
+- express-validator - Request validation
+- swagger-jsdoc - API documentation
+- Existing types from @types/agent.ts
