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

Annotations indicate readOnlyHint=false and destructiveHint=false, so the tool is not read-only or destructive. The description adds permission and access context but does not explain what 'reuse' actually does (e.g., create a copy, reference, or modify). There is no contradiction with annotations, but the behavioral effect is vague.

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 four sentences long, with the purpose stated first. It is efficient and front-loaded, but the second to fourth sentences could be slightly condensed without losing meaning.

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?

The description covers the core purpose and usage constraints thoroughly, but it lacks parameter descriptions and does not specify the return value or effect of the tool (e.g., whether it creates a new asset or modifies an existing one). For a simple tool with no output schema, this gap reduces completeness.

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 input schema defines two parameters (assetId, communityId) with no descriptions, resulting in 0% schema coverage. The description does not explain what these parameters represent or how they relate to the tool's purpose. The agent must infer meaning from names alone, 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: 'Reuse an existing Magic Content asset.' The verb 'reuse' is specific and distinguishes from siblings like generate_magic_content or delete_magic_content. However, 'reuse' could be interpreted as duplicate or repurpose; a more precise term like 'duplicate' would improve clarity.

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 usage guidance: it states that FREE businesses cannot use this tool, requires calling check_business_tool_access before collecting inputs, and mandates showing grace-period warnings and resubscribe links. It also says 'never proceed when access is blocked,' which clearly defines when not 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.
