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

With no annotations, the description carries behavioral disclosure. It explicitly states that the tool only lists bounded tenant-owned notifications and does not advertise external webhook delivery, preventing false expectations. It does not mention auth or output details, but the non-webhook disclosure is substantive.

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?

Two sentences with no filler. The main action and scope are front-loaded, and the webhook clarification is a single additional sentence that earns its place.

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 simple list tool with two optional parameters, this is adequate, but the lack of annotations and output schema leaves return shape, pagination, and permission context unspecified. The description covers the tool's boundary but not its full operational context.

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%, so the description needed to compensate, but it does not explain limit or state beyond what the schema already shows. The schema provides types, defaults, and the unread/read enum, yet the description adds no parameter-level meaning.

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 uses a specific verb ('List') and a clearly scoped resource ('bounded tenant-owned TikTok in-app optimization notifications'). It also clarifies the notification domain and avoids confusion with notifications_mark_read.

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 gives useful context, especially the 'does not advertise external webhook delivery' exclusion, but it does not explicitly name alternatives like notifications_mark_read or state conditions for when to choose this tool over siblings. Usage is implied rather than prescribed.

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