A3.7/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered structurally. The description adds the 'current account' scoping context but says nothing about result size, ordering, pagination, or whether inactive webhooks are included.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single short sentence with the scope qualifier ('for the current account') front-loaded. No filler, nothing repetitive of the title beyond the necessary verb+resource.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter read-only list tool with rich annotations, the description covers what the tool returns at a high level. The lack of an output schema means a note on response shape or pagination would have helped, but that is a minor gap for a tool this simple.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there are no parameter semantics to convey; the baseline of 4 applies. Nothing in the description contradicts or misdescribes the parameterless signature.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb+resource ('List all webhook subscriptions') and scopes it to the current account. However, it does not distinguish itself from close siblings such as list_webhook_deliveries, which an agent could easily confuse with this tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'List all webhook subscriptions for the current account' implies the intent (enumerate configured webhooks) but gives no explicit when-to-use/when-not guidance. It notably omits a clarification against list_webhook_deliveries, leaving the agent to infer the difference from the name alone.

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