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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is clear. The description adds that the offer is free and priced at 0 SEK, but it does not disclose return format, availability conditions, or any behavior beyond the offer label.

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 concise sentence with no wasted text. It is front-loaded with the offer name and price, though it reads as a fragment rather than a fully structured tool description.

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 tool with annotations covering safety, the description still needs to clarify what the tool returns and when to use it instead of sibling tools like request_free_first_task. It states the offer's price but leaves the agent without enough context to confidently select or understand the call.

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. The empty input schema is consistent with the description, and there are no parameter semantics to clarify.

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 identifies the offer as the 'Free entry offer (Free First Task)' with price 0 SEK, but it is a noun phrase rather than a clear verb+resource statement. It does not explicitly say the tool returns or retrieves this offer, and it does not distinguish the tool from closely related siblings such as request_free_first_task or get_pricing_model.

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 on when to use get_offer versus alternatives like request_free_first_task or get_pricing_model. The description provides no context, prerequisites, or exclusions to help an agent select this tool correctly.

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