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. It implies a read but says nothing about auth requirements, whether the post and comments are returned together or paged, or what happens for a missing/private id.

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 compact sentence with the scope front-loaded and no filler. It is terse to the point of under-specification, but nothing is wasted.

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?

With no output schema, the description's mention that comments come back with the post is genuinely useful. However, for a fetch tool with no annotations it should also cover id validity, auth, and whether comments are truncated or paged.

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 only one parameter exists. 'By id' weakly signals that the id identifies the post, but the description adds no format, type, or source detail (e.g., numeric vs. slug id) beyond what the bare schema already shows.

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 (Fetch) and resource (one post and its comments) with the lookup key (by id). It is clearly separable from write-oriented siblings like hiveposts_create_post or hiveposts_update_post, though it does not explicitly contrast with read siblings such as hiveposts_post_versions or hiveposts_search.

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?

No indication of when to use this versus hiveposts_search, hiveposts_feed, or hiveposts_post_versions when a caller already has an id. No prerequisites or exclusions are stated.

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