Create profile

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

Annotations indicate non-read-only and non-destructive, aligning with the creation nature. The description adds 'logical container for connected socials', which provides context but does not disclose side effects (e.g., username uniqueness constraints, required permissions, or what happens on duplicate usernames). Adequate but has gaps.

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 of 8 words, front-loaded with the key action and resource. No wasted words – every word adds value.

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 single-parameter tool with an output schema, the description explains the purpose adequately but omits behavioral details (e.g., what happens on duplicate username) and parameter semantics. The output schema likely covers return values, so that gap is partially mitigated, but overall completeness is average.

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 does not describe the 'username' parameter at all. The description adds no meaning beyond the schema's type and required status, failing to compensate for the lack of schema descriptions.

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 clearly states the verb 'Create' and the resource 'Upload-Post profile (logical container for connected socials)', distinguishing it from siblings like create_media_upload which targets media uploads, or delete_user which deletes users.

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 tool over alternatives. For instance, there is no mention of prerequisites (e.g., authentication) or when to use it vs delete_user or update tools. The description only states what it does, not when or when not to use it.

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