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

With no annotations, the description carries the full burden, yet it only says what is checked, not what the behavior is: no indication of whether it requires auth, what the response shape looks like (status enum, boolean flag), or whether it is rate-limited. For a diagnostics endpoint, the return semantics are the whole point and they are absent.

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?

One tightly-worded sentence, front-loaded with the primary purpose. No filler, no restatement of the title.

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 a zero-param read tool this is close to adequate, but with no output schema and no annotations, the description should have sketched what the caller gets back (health state and whether registration is open) so the agent knows what to do with the result. As written, the result contract is unspecified.

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?

The tool takes zero parameters and has no properties, so there is nothing for the description to disambiguate. Baseline 4 applies; no parameter guidance is needed or missing.

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 ('Check') and two concrete resources (API health, open registration status), which is unambiguous and could not be confused with sibling content tools like hiveposts_register or hiveposts_me. It does not explicitly name a sibling it is *not*, but the scope is self-evident.

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?

The description never says when to reach for this tool — e.g. before attempting registration, when other calls fail, or as a diagnostics probe. No alternatives or preconditions are mentioned; usage is left entirely to inference from the tool name.

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