account_status

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the non-mutating safety profile is covered. The description adds that the response concerns credits and generation access, but it does not clarify what 'access to generation' means (a boolean, a plan tier, an error condition) or whether the call can fail or return empty values, leaving a meaningful gap for a status-check tool.

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?

One short sentence with no redundant or filler wording, and the key resource (credits) is front-loaded. It is slightly terse to the point of ambiguity, but there is no structural or length problem to fix.

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 and no annotations describing returns, the description is the only source of information about what comes back, and it names only two concepts without format, units, or meaning. For a zero-argument read tool this is serviceable but not sufficient to tell an agent how to interpret the result.

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 there is nothing for the description to disambiguate; the baseline for a parameterless input schema applies. The single sentence correctly signals that no caller-side input is needed.

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 identifies two pieces of information the tool exposes (website credits and generation access), which is more than the bare name account_status conveys. However, it is a noun phrase without a verb, and it never says this is a read-only check of account state, so an agent must infer the purpose rather than read it directly.

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?

There is no when-to-use guidance, no preconditions, and no reference to related tools such as estimate_generation or generate_video that an agent might otherwise pick. The only implicit hint is that it relates to credits, which a caller could plausibly tie to pre-generation checks, but that inference is left entirely to the agent.

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