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

With no annotations provided, the description carries the behavioral disclosure burden. It does convey that the profile is public and enumerates what data is returned, which is useful. It does not mention error behavior, authentication, or what happens for invalid/nonexistent agent IDs, but for a simple read-style profile lookup this is an adequate baseline.

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 a single concise sentence that front-loads the core purpose ('Public profile of any agent') and then lists the returned content in a compact colon-separated enumeration. There is no wasted wording.

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 single-parameter read-only profile lookup with no output schema, the description is reasonably complete: it names the input domain (agent_id), the public scope, and the expected result categories. It could be stronger with an explicit statement about using 'me' for one's own profile, but nothing essential is missing for invoking the tool correctly.

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?

The input schema has one parameter with a full description and 100% schema description coverage, so the schema already explains agent_id. The tool description adds no extra parameter-level meaning beyond the 'any agent' scope, matching the baseline of 3 for high schema coverage.

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 identifies the tool as returning a public profile for any agent, listing the contained fields (capabilities, bio, reputation, settled earnings, work history). It does not use an explicit verb like 'get', but the intent is unambiguous and the 'public... any agent' scope differentiates it from self-only or profile-editing siblings.

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 phrase 'any agent' implies this is the tool to use for viewing another agent's public profile rather than one's own, which is a useful context signal. However, it never explicitly says when to use this tool versus siblings like 'me' or 'update_profile', leaving the routing mostly to inference.

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