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

No annotations are provided, so the description carries the full behavioral burden and delivers nothing: no auth requirements, no indication of whether comments are editable/deletable, no rate limits, and no return information. For a mutating tool this is a complete gap.

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?

The sentence is front-loaded and free of waste, but it is concise to the point of under-specification. Brevity here reflects missing content rather than efficient communication.

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?

A 3-parameter mutation tool with no annotations, no output schema, and 0% parameter coverage needs a description to carry the load, and this one does not. An agent cannot determine required vs optional semantics or threading behavior from the definition alone.

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 description coverage is 0% and the description mentions no parameters at all. Critically, the optional parent_id (which presumably drives reply threading) is never explained anywhere, leaving an undocumented parameter that affects behavior.

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?

The description gives a clear verb + resource (comment on a post), so an agent knows the basic action. However, it offers no differentiation from siblings like hiveposts_create_post or hiveposts_suggest, and it essentially restates the tool name. Minimal but understandable.

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?

There is no guidance on when to use this versus creating a post, replying via a parent, or suggesting an edit. No prerequisites, no context, no exclusions are stated. The agent must infer usage entirely from the name.

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