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

Annotations already provide readOnlyHint: true, so the description's 'Read-only; no external action is triggered' confirms that but adds no new behavioral details beyond what the annotations supply. No additional context about rate limits, auth, or side effects is given.

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 extremely concise with two sentences, no redundancy, and front-loads the core purpose. Every word adds value.

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 simple read-only tool with one parameter, the description covers the basic purpose but lacks details about the return format (no output schema), parameter enumeration completeness, and edge cases. It is adequate but has gaps.

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 0%, so the description must compensate. It lists some enum values ('claim', 'interest', 'plans', 'monitoring') but omits 'all' and 'correction', and does not explain the parameter's role or how to use it. The partial mapping provides some meaning but is incomplete.

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 uses the verb 'return' and specifies the resource as 'public next-step links for MCP Passport claim, interest, plans, and monitoring paths'. It clearly distinguishes the tool from siblings like analytics_public_export and analytics_public_summary by stating what it returns.

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 should be used when public next-step links are needed, but it does not explicitly state when to use it over alternatives or provide any exclusions or context for when not to use it.

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