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

No annotations, so the description carries the full burden. It adds only that the caller owns the created account; it omits auth/permission requirements, what 'private beta' gates, and irreversibility of account creation.

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 short, front-loaded sentences with no waste; the ownership note follows the core action efficiently.

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, no annotations, and undocumented parameters, the description leaves too much unspecified for a creation tool. It should disclose auth needs and what terms_version expects.

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?

Schema coverage is 0% and the description explains neither parameter. 'terms_version' in particular is unexplained (which version, where to obtain it), leaving an agent unable to populate it confidently.

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 ('Create') and resource ('developer platform account'), and 'the caller owns it' clarifies the result. It is distinguishable from siblings platforms_list and platforms_revokeManage, though 'platform account' remains somewhat opaque.

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 on when to use this versus platforms_list or platforms_revokeManage, and no prerequisites beyond the parenthetical '(private beta)'. An agent gets no context about eligibility or gating.

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