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

The readOnlyHint and destructiveHint annotations already establish the safe read-only nature of the tool. The description adds only mild domain context ('Peerlytics' and 'profile') and does not describe response shape, address format, or failure behavior, so it provides limited value 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 one short, front-loaded sentence with no filler. It is concise and readable, though it is so minimal that it misses opportunities to add routing or usage context that would make it more useful.

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 read-only tool with one required parameter and clear schema coverage, the minimal description is workable. However, with no output schema and no mention of alternatives among the many peer_market_explorer_* siblings, the agent gets only the bare essentials for correct invocation.

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 100%, and the only required typed parameter, 'address', is documented as 'Verifier address.' The description adds no additional parameter-level meaning, so the baseline 3 is appropriate.

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 states a specific action ('Look up') on a specific resource ('verifier profile') within a named domain ('Peerlytics'). It is clear, but it does not explicitly distinguish itself from the many sibling explorer tools such as peer_market_explorer_maker or peer_market_explorer_address.

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?

No usage guidance is provided. The description does not say when to prefer this tool over alternatives, nor does it mention any exclusions or related tools, which is a notable gap given the large sibling list.

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