Show HN: Kastor – Terraform-style specs for AI agents
TL;DR
Kastor introduces a declarative specification system for AI agents, akin to Terraform, addressing the lack of a vendor-neutral source of truth. It allows users to define agents using typed specifications and manage them as long-lived resources across various platforms.
✦ Why It Matters
Engineers can adopt Kastor today to standardize their AI agent specifications and improve collaboration across teams.
Key Takeaways
- Use Kastor to define AI agents in a vendor-neutral format.
- Leverage 'kastor build' to generate projects for various frameworks.
- Implement 'kastor plan' and 'kastor apply' for state management.
- Adopt version control practices for AI agent specifications.
Full Summary
Current frameworks for AI agents often rely on imperative definitions or graphical user interfaces, leading to a lack of standardization and version control. Kastor offers a solution by providing a typed, declarative specification format (.agent, .tool, .prompt files) using HashiCorp Configuration Language (HCL).
It includes a Go toolchain with commands like 'kastor build' to generate runnable projects and 'kastor plan'/'kastor apply' to manage agents as persistent resources. This system supports state management, diffs, and drift detection, ensuring that agents remain consistent with their specifications over time.
By enabling versioning and reviewability, Kastor enhances collaboration and maintainability in AI agent development. The implications for engineers include improved control over agent configurations and easier integration across different platforms.
