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

It adds meaningful behavioral context beyond the annotations: creation counts against a community plan cap and requires a connected account. This helps the agent anticipate side effects and preconditions. There is no contradiction with annotations.

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 brief and front-loaded with the action and resource. Every sentence adds relevant information—fields, cap impact, and account requirement—with no filler.

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 9-parameter creation tool with a nested object, required fields, and no output schema, the description is incomplete. It does not explain all parameters, success/failure behavior, or output, and relies too heavily on the schema for essential details.

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?

With 0% schema description coverage, the description carries the burden of parameter explanation. It names a few fields and gives the privacy enum values, but it omits important parameters like home_city and short_description, and provides no detail on required constraints or category enum values.

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'), the resource ('community'), and the ownership aspect ('you own'). It also enumerates the main fields involved, making it easy to distinguish from sibling tools like update_community or list_my_communities.

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?

The description provides useful context such as the plan cap and connected-account requirement, implying when this tool is appropriate. However, it does not explicitly name alternatives or conditions for when not to use it, leaving the usage guidance mostly implicit.

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