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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description goes beyond that by naming the actual data categories returned, which helps an agent decide whether this call supplies the context it needs. It stops short of noting auth requirements or freshness of the credit count.

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?

A single front-loaded sentence that carries real information with no filler. The enumerated list is long but each item maps to a distinct piece of account state an agent might need.

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 carries the burden of conveying the return shape, and it does so at a summary level by naming the four categories of account data. Slightly more detail on response structure or the credit-count semantics would complete it.

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 and the schema is trivially complete, so there is nothing for the description to clarify. Baseline of 4 applies since no parameter ambiguity exists.

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 (shows) and resource (the signed-in account) and then enumerates exactly what the account view contains — company/agency identity, remaining publishing credits, auto-check vs. human-approval publishing mode, and agency client companies. This is unambiguous and easily separable from the release-oriented 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?

Usage is implied by the content: an agent would call it to discover account tier, credits, or publishing mode before publishing. However, there is no explicit when-to-use statement, no mention of prerequisites (e.g., that the caller must be authenticated), and no exclusions or alternatives named.

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