AgentSeed vs mastermind

AgentSeed: AgentSeed provides anti-hallucination guardrails for AI coding agents, ensuring generated code is verified before being marked as complete. It offers a suite of five MCP tools to catch invented APIs, overclaims, and non-conformant plugin packaging, binding instructions to a hard gate for reliable code verification.; mastermind: Mastermind provides AI coding agents with a structural view of your code, showing components, dependencies, and potential change impact, while offering a verifiable workflow to validate agent plans against the real repository. It aids in understanding unfamiliar repositories, safely modifying code, selecting focused tests, and auditing agent work through its local codegraph and deterministic style miner.
