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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is clear. The description adds useful behavioral context by identifying the returned content as steps plus signup, showroom, and free-check URLs, though it could say more about the response format.

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 definition is two compact sentences with no waste, and the main purpose and step summary are front-loaded. The usage phrase is appended efficiently and earns its place by clarifying intent.

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 parameters, no output schema, and strong read-only/idempotent annotations, the description provides enough context for an agent to know this is an informational guide tool. It also mentions the content it returns, which is sufficient for this simple tool.

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 the baseline is 4 under the scoring rules. There are no parameter semantics to clarify, and the description does not create confusion about inputs.

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 states a specific how-to purpose: opening a Korean internet newspaper with OnPress, and lists the concrete steps (sign up, name the paper, connect sources, register, go public). It does not explicitly differentiate itself from sibling guide tools such as get_guide or search_guides, so it stops short of a 5.

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 gives an explicit usage trigger: use for "인터넷신문 어떻게 만들어?". That tells the agent the right context, but it does not state when not to use it or name the sibling alternatives for broader or different guide searches.

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