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

The description only says 'Gets,' implying read-only, but with no annotations provided, it should explicitly state behavior traits like idempotency, safety, or authorization needs. This is a missed opportunity.

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 sentence, very concise. While it could be more informative, every word earns its place, and it is front-loaded.

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 complexity of having many sibling tools and an output schema, the description is adequate but not complete. It fails to clarify what 'comprehensive' means or how it differs from similar tools.

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?

There are no parameters, and schema description coverage is 100% (vacuous). The description adds nothing about parameters, which is acceptable since none exist. Baseline 4 is appropriate.

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 states it 'Gets comprehensive account features and settings,' which clearly indicates the action and resource. However, it does not distinguish itself from sibling tools like account_details, account_info, account_profile, or account_settings, making it less helpful for selection.

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 guidance is provided on when to use this tool versus its many siblings. There are no context cues, exclusions, or alternative suggestions, leaving the agent to guess.

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