What neither does

Both fail llms-full.txt / full agent docs, structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, machine-readable errors, retry behavior documented, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
