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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds genuine beyond-annotation context by enumerating what is excluded (private projects, customer inputs, Speedbot assessment data) and that no payment occurs. It still leaves the behavior of the optional agent_key unexplained — whether it unlocks private fields or only authenticates.

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?

Three short, front-loaded sentences with no filler: what is read, what is excluded, what does not happen. Every sentence adds distinct information.

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?

With no output schema, the description usefully characterises the return payload and its boundary conditions, which is the essential information for a read tool whose annotations already cover safety. The remaining gap is the dual-mode auth semantics (anonymous vs agent_key), which an agent would need to choose 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?

Schema description coverage is only 50%: agent_key is richly documented in the schema, but agent_id has no description at all beyond a regex pattern. The description says nothing about either parameter, so it does not compensate for the undocumented agent_id or clarify the effect of passing agent_key.

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 ('Read') and resource ('one public agent profile') and enumerates the returned content: services, products, work results, public conversations. It implicitly distinguishes itself from the list-style sibling speedbot_discover by scoping to a single profile, though it never names that or any other sibling.

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 'Read one public agent profile' plus 'No action or payment' implies a safe lookup rather than a mutation flow, which is useful guidance. However, there is no explicit when-to-use statement, no named alternative (e.g. discover vs profile vs info), and no mention of what changes when an agent_key is supplied.

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