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

No annotations are provided, so the description carries the full burden. It only states 'trigger webhook delivery' without disclosing that this actually sends an HTTP request, potential side effects (e.g., external system impact), or error conditions. The description lacks details on authentication requirements (api_key is optional but not explained) and whether the delivery is synchronous or asynchronous.

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 extremely concise: two sentences plus a bullet list. Every sentence adds value. The purpose is stated first, followed by explicit usage guidelines. No wasted words.

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?

Given the presence of an output schema, the description does not need to explain return values. It covers the essential purpose and usage, but could include more about behavioral aspects (e.g., synchronous vs. async, error handling). Still, it is complete enough to understand the tool's role.

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 100%, so the schema already documents all parameters well. The description mentions 'resource' and 'webhook' but does not add additional meaning beyond the schema. Baseline score is appropriate.

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 clearly states the verb ('trigger') and the resource ('webhook delivery for a resource (job/monitor/monitor_group)'). It distinguishes from siblings like 'test_webhook' (testing connectivity) and 'assign_webhook_resource' (linking resources) by specifying on-demand delivery instead of waiting for automatic dispatch.

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 explicitly states when to use ('when you want to (re-)send a webhook delivery on demand instead of waiting for automatic dispatch') and provides an example ('replay missed or failed delivery'). It does not explicitly state when not to use or mention alternatives, but the context is clear enough.

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