codex_account_status

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

Annotations already declare readOnlyHint=true and openWorldHint=false, and the description's 'verifica' is consistent with a read-only check. The description adds some behavioral context by enumerating what is verified (auth, plan, Codex, imagegen availability), but does not disclose response shape or failure/edge behavior.

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 sentence with no filler, front-loading the verb and main subjects. The cryptic '$imagegen' prefix looks like an unresolved template variable, which slightly detracts from polish, but overall the description is appropriately sized.

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?

For a zero-parameter, read-only status tool this is mostly adequate: it names what is checked and the annotations cover the safety profile. However, with no output schema, it would benefit from hinting at what the response contains, and the $imagegen term plus sibling overlap with imagegen_status remain unresolved.

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 has zero parameters, so the baseline is 4 per rubric. The description need not explain parameter semantics, and the empty schema confirms no arguments are required.

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 uses a specific verb 'Verifica' (verifies) and names its targets: ChatGPT authentication, plan, Codex, and $imagegen availability. The scope is clear, but it does not differentiate from the sibling imagegen_status, which likely also reports on imagegen availability.

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 given on when to use this tool versus imagegen_status, generate_image, or edit_image. With a closely related sibling like imagegen_status, the potential for mis-selection is real and unaddressed.

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