Reviewer Notes

Weave has a solid free tier and sandbox environment, which is good for agent experimentation. However, discovery is hampered by the lack of an OpenAPI spec, MCP server, or llms.txt file—agents cannot easily understand the API surface without manual documentation review. The OAuth2 + API key authentication and absence of programmatic signup means agents cannot self-onboard. The SDK exists but documentation on structured error handling and observability APIs for agents is limited. Overall, Weave is better suited as a backend for human-managed agent development than for autonomous agent discovery and self-service integration.
