Kingy AI Take
Important because it productizes the agent infrastructure behind Claude Code rather than leaving teams to recreate orchestration patterns.
Who it is for
Developers who want to build agents with Claude Code-style memory, permission, and subagent patterns.
What feels promising
SDK-level access can help teams make more durable agent workflows with permissions and memory handled more deliberately.
What feels unproven
The SDK still requires careful design around tool permissions, prompt injection, data boundaries, and evaluation.
