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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the description need not restate them. It adds content scope (banking tips, promotion guides, financial education) but no additional behavioral traits like pagination, limits, or authentication. With annotations covering the safety profile, a neutral 3 is appropriate.

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 two sentences, front-loaded with the primary purpose ('Get published blog articles') followed by a concise list of content types. Every word earns its place, with no fluff or repetition.

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-parameter, read-only tool with no output schema, the description adequately conveys that it returns blog articles and the topics covered. It does not specify the return format or article metadata, but given the simplicity of the tool and strong annotations, this does not hinder agent selection or invocation.

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 zero parameters, so there are no parameter semantics to describe. Per the baseline rule, 0 parameters earns a 4. The description does not need to compensate for any schema gaps since the schema is fully complete (empty object).

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 states 'Get published blog articles from RozbijBank' with a specific verb and resource, distinguishing it from sibling tools like GetBanks or SearchDeposits. It also adds context on content categories (banking tips, promotion guides, financial education), making the purpose unmistakable.

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 implies usage when blog articles are needed, and clearly differentiates the content focus from sibling tools. However, it does not explicitly state when to use this tool over alternatives or mention any exclusions, so the guidance remains implied rather than explicit.

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