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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is provided structurally. The description adds meaningful behavioral context by specifying that access relies on a private read token, which is important authentication information not covered by 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, front-loaded sentence with no filler. It conveys the operation, the resource, and the auth requirement in twelve words, which is appropriately concise for a simple read tool.

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 read operation with safety annotations and only two required parameters, this is minimally viable. The main missing piece is explicit meaning for the id parameterasi; an agent would likely infer it refers to the inbox id, but the description does not state that directly. No output schema exists, so return values are also unspecified, though 'read' implies the inbox content.

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 schema has 0% description coverage for its parameters不可, so the description must compensate. It clarifies that 'token' is the 'private read token', but it does not explain that 'id' identifies the webhook inbox or describe the expected format of either parameter. This is only partial compensation for the schema gap.

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 a clear verb ('Read') and resource ('webhook inbox'), and the mention of the private read token hints at the auth mechanism. This distinguishes it from hookbox_create_inbox and hookbox_delete_inbox at a glance, though it does not explicitly name the sibling alternatives.

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?

No guidance is given on when to use this tool versus the other hookbox read/create/delete tools or other read tools like cleanread_read_page. The only hint is the read-only action itself, with no exclusions, preconditions, or alternative routing.

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