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

With no annotations provided, the description carries the full behavioral burden. It adds useful scope ('published') and result content, but it does not disclose read-only behavior, ordering, pagination, or authorization needs. This is minimally adequate for a simple list tool, but not rich.

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 description is a single short fragment with no filler; every word contributes to the resource and output fields. It is appropriately sized and front-loaded for a zero-parameter tool.

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 no-argument list tool, the description is nearly complete: invocation requires no input, and the description states what is returned. However, with no output schema or annotations, it could better distinguish this from siblings and mention ordering or pagination.

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 input schema has zero parameters and 100% schema coverage, so the baseline of 4 applies. There is no parameter semantics for the description to add beyond the empty schema.

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 clearly identifies the resource ('published posts') and the fields that will appear ('descriptions and citation URLs'), so an agent can infer this is a listing tool for writing content. However, it lacks an explicit verb and does not differentiate itself from siblings like search_writing or get_post.

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 about when to use this tool versus search_writing or get_post, and no exclusions or prerequisites are mentioned. The phrase 'Published posts' implies a usage context, but the description never states a selection rule.

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