1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Start New Sessions: Initiate a new conversation with a specific Claude model.
Continue Sessions: Reply to existing sessions using their Session ID.
Session Management: Automatically continues the latest session if no Session ID is provided.
Model Selection: Supports specifying different Claude models (e.g., sonnet, opus, haiku).
System Prompt: Native support for custom system prompts.
Working Directory: Specify custom working directory for CLI execution.
