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

Annotations indicate a non-read-only, non-destructive mutation. The description adds the key behavioral detail that 'Reporter emails are hidden on shared views', which is not covered by annotations. It correctly implies the link is read-only for viewers, while the creation action is a write, consistent with readOnlyHint=false. No contradictions.

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 long, with no wasted words. The first sentence clearly states the action and purpose, the second adds an important privacy detail. It is front-loaded and efficient.

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 (2 required 1), existence of an output schema (not shown but present), and rich sibling context, the description covers the essential purpose, behavioral trait (email hiding), and usage context. It is complete for an agent to correctly select and invoke the 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?

Schema coverage is 50% (only expires_in_days has a description). The tool description does not add any parameter-specific semantics beyond the schema; project_id is mentioned only implicitly as 'for a project'. The description should clarify what project_id is, but it doesn't.

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 verb 'Mint' and the resource 'read-only public review link for a project', with a specific purpose 'so a stakeholder can review its annotations without an account'. It distinguishes from siblings by focusing on share link creation, a unique function among the listed tools.

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 for when to use: when a stakeholder needs to review annotations without an account. It implicitly suggests it over alternatives like giving an account, but does not explicitly exclude other scenarios or mention when not to use.

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