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

No annotations are provided, so the description carries the full disclosure burden. It implies a read operation but says nothing about pagination, ordering, whether inactive/disabled subscriptions are included, return shape, or permission requirements for the calling bot.

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?

A single front-loaded sentence with zero wasted words. It is efficient, though it verges on under-specification rather than being an exemplary tight definition.

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 one-parameter read tool with no output schema and no annotations, the description is minimally adequate: an agent knows what it fetches and for which bot. It omits all scoping behavior (pagination, filtering, ordering) that an agent would want before relying on the result set.

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?

There is one parameter with 0% schema description coverage. The phrase 'for a bot' implicitly maps bot_id to the owning bot, but the description adds no format, source, or lookup guidance beyond that bare association.

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 ('List') and resource ('event-webhook subscriptions') scoped to a bot, which is enough to tell it apart from create_webhook_subscription and delete_webhook_subscription among the siblings. It stops short of any explicit sibling differentiation, but the verb+resource pairing is unambiguous.

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 statement of when to use this versus create/delete webhook tools, no prerequisites, and no mention of what to do next after listing. Usage is only implied by the tool name and the 'List' verb.

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