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

Annotations indicate a non-read, non-destructive operation. The description adds transparency about authorization requirements, specifically that business permission checks are mandatory and that free-tier businesses are blocked. It also warns about showing grace-period warnings and resubscribe links, which are behavioral constraints beyond mere 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 a single paragraph that covers purpose and usage guidelines, but it lacks structural elements like bullet points or sections. While it is relatively concise, the block of text could be easier to parse with better formatting.

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?

Given the tool has 9 parameters (2 required) and no output schema, the description is incomplete. It fails to explain what the generated prompt is used for, what inputs are needed, or the expected output. The focus is entirely on access checks, leaving many gaps for an AI agent to operate effectively.

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 description coverage is 0%, and the description provides no information about parameters. It does not explain what 'communityId', 'assetType', or other parameters mean or how they affect the prompt generation. The agent must rely solely on parameter names and types, which is insufficient.

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 action: 'Generate a creative direction prompt for Magic Content.' This distinguishes it from sibling tools like 'generate_magic_content' (which creates actual content) and 'generate_lead_form' (a different domain). The verb 'generate' and resource 'creative direction prompt' are specific.

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 explicit, step-by-step usage instructions: check business permissions first, note that FREE businesses cannot use it, call 'check_business_tool_access' before collecting inputs, show grace-period warnings and resubscribe link, and never proceed when access is blocked. This clearly tells the agent when and how to use the tool.

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