What your agent reads
The tool description exactly as an MCP client receives it in tools/list — it doubles as the full behaviour of the endpoint.
Before creating: how many people a profile's posts draw per month (its last 30 days of posts: likes, comments) or one post's counts, and the records that would cost if every one of them were delivered — comments only vs with reactions. One vendor call, no record cost. Personas deliver a fraction of this.
Errors follow one format.
