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

With no annotations, the description must carry behavioral context. It discloses that pricing is read live from a public endpoint and that wholesale cost transparency is included, but it does not state freshness guarantees, error behavior, or caching characteristics.

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 tight sentence plus a no-arguments note. The purpose and scope are front-loaded with zero wasted words.

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, the description covers what data is returned (hosting plans, domain registration, wholesale cost transparency) and where it comes from. It could say more about the response shape since no output schema exists, but it is largely sufficient.

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, which sets a baseline of 4. The description reinforces this by explicitly stating 'No arguments,' leaving no ambiguity about invocation.

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 a specific verb and resource: reading current Slipdock pricing for hosting plans and domain registration. It adds useful scope details like wholesale cost transparency, but does not explicitly distinguish this tool from siblings such as get_slipdock_info.

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 the tool is for pricing lookups but gives no explicit when-to-use or when-not-to-use guidance. It also does not mention alternatives, even though sibling tools get_slipdock_info and how_an_agent_signs_up exist.

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