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

Annotations already indicate readOnlyHint=true and destructiveHint=false. The description adds behavioral context about access restrictions (checking permissions, grace periods), which complements the annotations. However, it does not describe the return format or pagination behavior, so it adds moderate value beyond the 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 with about 7 sentences. It is front-loaded with the main purpose and then covers preconditions. While it is slightly verbose, every sentence adds necessary context. It could be structured as bullet points for clarity, but it remains reasonably concise and focused.

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 10 parameters and no output schema, the description is incomplete. It omits any explanation of pagination, filtering, sorting, or the return structure. The heavy focus on access control leaves significant gaps in understanding how to use the tool 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% (no parameter descriptions in the input schema), and the tool description provides no information about the 10 parameters (e.g., pageNo, sortBy, status, etc.). The description should compensate for the lack of schema documentation but does not, leaving the agent uninformed about parameter meaning and usage.

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 states 'List unified products for a community managed by the authenticated Nas.com user.' It uses a specific verb and resource, and implies the scope is a community. However, it does not differentiate from sibling list tools like list_products_for_reordering or list_magic_audience_products, but the community context provides a degree of distinction.

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 explicitly says to check business permissions, notes that FREE businesses cannot use this tool, instructs to call check_business_tool_access before collecting inputs, and specifies to show grace-period warnings and never proceed when access is blocked. This provides clear when-to-use and when-not-to-use guidance, including an alternative prerequisite action.

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