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

With no annotations provided, the description carries the behavioral disclosure burden. It clearly reveals a key constraint: 'Returns titles, excerpts and dates only, never article bodies.' It does not discuss pagination, ordering, or access errors, but for a zero-parameter public listing tool this is reasonably transparent.

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?

Three sentences cover purpose, usage context, and output limitations with zero filler. The action and resource are front-loaded, followed by a clear when-to-use statement and then a precise scope constraint.

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?

Given there is no output schema, the description must explain return contents, and it does: titles, excerpts, and dates only. It also explains the relationship to fetching full article text)Skip, making the tool's role in the broader sibling set clear and self-sufficient for an agent.

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 has no parameters and the schema coverage is 100%, so there is no parameter meaning to add. The description instead clarifies what the listing contains)Skip — titles, excerpts, dates — making it clear why no parameters are needed for the stated use cases.

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 opens with a specific verb and resource: 'List SDUK Studio's published articles,' and further specifies the content categories covered. It also distinguishes itself from the sibling public-post by noting it returns slugs for fetching full text elsewhere.

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?

It explicitly states when to use it: when someone wants to browse or search the writing, or to find an article's slug before fetching its full text. It doesn't name sibling public-post as the alternative for full content, but the phrase 'before fetching its full text' clearly implies the routing.

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