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

With all annotation hints false, the description adds valuable behavioral context: the link is public, read-only, and hides reporter emails. It does not disclose potential side effects like link invalidation or rate limits, but for a simple create operation, it provides sufficient transparency beyond the annotations.

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 core action, and contains no superfluous information. The second sentence adds a privacy-relevant detail without bloating the text.

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?

Given the low parameter count and presence of an output schema, the description sufficiently covers the tool's purpose, access model, and privacy behavior. It could mention the output (the share link URL) but that is presumably handled by the output schema.

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?

Schema description coverage is 50%: only 'expires_in_days' has a description, while 'project_id' does not. The description adds no parameter-specific meaning, merely referring to 'a project' without clarifying the ID format or required field. It fails to compensate for the uncovered parameter.

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 function with a specific verb ('Mint') and resource ('read-only public review link for a project'), and adds the purpose ('so a stakeholder can review its annotations without an account'). It distinguishes itself from sibling tools, none of which create share links.

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 provides clear context on when to use the tool: to share a project with external stakeholders who need read-only review access without an account. It does not explicitly name alternatives or exclusions, but the use case is unambiguous given the sibling tool set.

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