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

No annotations are provided, so the description carries the full burden. It accurately describes the content (a how-to guide) but does not explicitly state that this is a read-only informational tool or describe any side effects. The instructional nature implies no mutation, but the description could be more 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?

The description is a single, concise sentence that front-loads the purpose and lists key topics in a structured, easy-to-scan manner. Every word contributes value, with no redundancy.

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 documentation tool with no parameters or output schema, the description covers the essential aspects: authentication, eligibility criteria, deposit fields, and endpoint. It lacks an explicit statement about the return format or examples, but it is sufficiently complete for understanding the tool's role.

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?

There are zero parameters in the schema, so the baseline is 4. The description does not need to add parameter-level details, but it does mention deposit fields as part of the guide's content, which adds context without conflicting with the empty schema.

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 the tool's purpose: to explain how to contribute an object. It specifies the key components (authentication, eligibility, deposit fields, endpoint), making it distinct from sibling tools that focus on querying or authentication.

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 intended use is implied (when one wants to contribute an object), but the description does not explicitly mention when not to use it or point to alternative tools. The sibling context suggests it is the contribution guide, but no explicit guidance is given.

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