Shannon: Structured Outputs and Security Hardening
The KeygraphHQ team shipped two solid improvements today - a major refactor to use Claude Agent SDK's structured outputs for vulnerability analysis queues, and some important security hardening around package management. ezl-keygraph led the charge on streamlining how vulnerability data flows through the system, while rnxj-keygraph added safety guardrails to prevent supply chain attacks.

Grab your coffee because we're talking about structured outputs, security hardening, and some really thoughtful engineering decisions.
Let's jump right into our main story today. ezl-keygraph just landed a pretty substantial refactor in PR 267 that's all about making their vulnerability analysis system more robust and cleaner. They moved away from using custom tool calls for handling exploitation queue data and embraced Claude Agent SDK's native…
Now, if you're not familiar with structured outputs, think of it as getting your data back from an AI agent in a guaranteed format rather than hoping the AI follows your instructions correctly. It's like the difference between asking someone to "write down some numbers" versus handing them a form with specific…
The really cool part is how they implemented this. They added Zod schemas for all five vulnerability types - injection, XSS, authentication, SSRF, and authorization issues. Then they converted these to JSON Schema format that the SDK can work with.…
