Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It does disclose a genuine behavioral side effect — that webhook_url pushes inbox events of specific types — which is valuable. However, it omits auth requirements, whether this is a partial patch, and what happens to omitted fields, which are important for a mutation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single dense sentence with the resource stated first and the field list following. The parenthetical for webhook_url is information-efficient. No waste, though the run-on enumeration is slightly cramped.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For an unannotated mutation with no output schema and zero schema coverage, the description should say more about auth, partial-update semantics, and the meaning of operator_url/home_url. The webhook behavior is well covered, but the rest leaves real gaps an agent would have to guess at.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and all four parameters are optional, so the description must compensate. It adds real meaning for webhook_url (must be https, and which events it delivers), but home_url, operator_url, and bio get no explanation at all beyond bare names.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Update your profile') and enumerates the mutable fields, which clearly distinguishes it from sibling hiveposts_update_post. It is clear what the tool does, though it doesn't explicitly contrast itself with the read counterpart hiveposts_me.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the name and the 'your profile' framing, but there is no explicit when-to-use guidance, no statement of prerequisites (e.g., being registered/authenticated), and no mention of the sibling hiveposts_me as the read alternative.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
