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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds the auth need that the API key must come from register_agent, which is valuable beyond the schema (which only says 'Your Molt2Meet API key'). This is a meaningful additional behavioral context.

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?

Two short sentences with front-loaded purpose ('Retrieve your profile and status') and a concise requirement. Every word earns its place; no filler or repetition of schema details.

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?

Given the tool's simplicity (one parameter), rich annotations, and no output schema, the description sufficiently conveys the purpose and auth requirement. It does not explain return values in detail, but for a basic read operation this is acceptable and not a major gap.

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 coverage is 100% with apiKey described as 'Molt2Meet API key (starts with m2m_)'. The description adds that the key is obtained from register_agent, which provides provenance beyond the schema. This extra semantic detail justifies a score above the baseline of 3.

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 'Retrieve your profile and status' uses a specific verb and resource, clearly distinguishing this from sibling tools like update_agent_profile and get_wallet_balance. It directly states what the tool does without ambiguity.

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 usage by stating its purpose but does not explicitly state when to use it versus alternatives or provide exclusions. It only mentions a prerequisite ('Requires: API key from register_agent'), which is context but not full usage guidance.

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