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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that results are paginated and project-scoped, which is genuinely useful behavioral context, but says nothing about result ordering, total counts, or pagination limits.

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 short sentences with no filler, and the core operation is front-loaded. The first line merely repeats the title, which is slight waste but harmless.

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-only list tool with annotation coverage this is close to adequate, but with no output schema the description should say more about what a webhook record or the paginated envelope contains. The nested 'request' object's page/pageSize semantics are left entirely to the schema.

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 reports 0% description coverage, and the description only indirectly signals the pagination parameters ('The list is paginated') and project scoping ('of the project'). It does not explain page defaults, pageSize bounds, or the nested 'request' wrapper, so it partially but not fully compensates for the coverage 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?

States a specific verb and resource ('List the webhooks of the project'), which clearly separates it from sibling mutations like webhooks-create/update/delete. It doesn't explicitly contrast with webhooks-retrieve, so it stops short of full sibling differentiation.

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 on when to use this versus webhooks-retrieve, nor any prerequisites or exclusions. The list/paginated framing implies enumeration but leaves the agent to infer the choice.

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