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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds genuinely new behavioral context: a signed-in inite.ai account is mandatory, and a guest call returns 401 and triggers the OAuth flow. It does not add rate-limit or pagination behavior, which is the main remaining gap.

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 sentences, each earning its place: the first enumerates returned fields, the second handles the auth precondition. Front-loaded with the resource description. Slightly dense with the colon-separated field list, but no wasted prose.

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?

An output schema exists, so return-value detail need not be spelled out, and the description still summarizes the payload. The auth requirement is disclosed. What remains thin is the absence of any sibling differentiation among the many atlas_owner_* tools, which is the one thing an agent might still need.

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 tool takes zero parameters, so the baseline is 4 per the rubric. There is nothing for the description to clarify beyond what the empty schema already conveys, and it does not introduce any confusing parameter-like phrasing.

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 names a specific resource and scope: 'The tools the signed-in account has claimed in the INITE Atlas', listing exactly the fields returned (verification status, badge link liveness, premium expiry, card address). That is far more concrete than a tautology. It does not, however, explicitly distinguish itself from sibling tools like atlas_owner_stats or atlas_owner_card that also concern the signed-in owner's data.

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?

Usage is only implied — an agent can infer this lists the caller's own claimed tools, but there is no explicit 'use this when…' or routing to alternatives such as atlas_owner_stats or atlas_owner_card. The auth condition (signed-in required, guest → 401) is stated, which is helpful context but not a when-to-use guideline.

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