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

No annotations, so the description carries the full burden; it discloses the shape of the returned data (endorsement history, recent activity), which is useful given there is no output schema. It says nothing about permissions, whether the lookup is read-only, behavior for an unknown agent_id, result limits, or freshness, leaving meaningful behavioral gaps.

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?

One front-loaded sentence that names the verb, the resource, and the payload with no filler or 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 one-parameter read tool with no annotations and no output schema, describing the returned contents is the right compensation. However, the relationship to check_reputation is left unexplained, and no access or error behavior is covered, so an agent can call it but may pick the wrong sibling.

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% for the single agent_id parameter, so the schema already documents the input fully. The description adds no format, source, or identifier-namespace detail beyond what the schema provides, making this the baseline case.

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?

States a specific verb (get) and resource (reputation profile) and enumerates the payload (endorsement history, recent activity). It does not explicitly distinguish itself from the sibling check_reputation, so an agent must guess whether 'full profile' vs 'check reputation' differ in scope.

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 when-to-use guidance and no mention of the obvious alternative check_reputation, whose name suggests a near-identical purpose. The only hint is the word 'full', which implies broader output but is not stated as a selection rule.

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