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

Annotations already declare `<readOnlyHint>true</readOnlyHint>` and `<destructiveHint>false</destructiveHint>`, covering the safety profile. The description adds the job-scoping context, which is useful, but provides no extra behavioral details such as authentication, pagination, or whether incomplete/removed webhooks are included. Modest, non-conradictory improvement over 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 entire description is a single, concise sentence with no waste. It is front-loaded and immediately communicates the verb, resource, and scope. No fluff or redundant details.

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 tool with one required, 100% schema-documented parameter and no output schema, this description plus annotations provide enough to call the tool. The core scope is clear, and the read-only behavior is standard. It could mention the global vs job-scoped contrast, but that is more of a usage guideline; in isolation little critical information is missing.

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 already fully details the only parameter (`id`: 'Job id or alias'), giving 100% coverage. The description simply echoes the relation to the job and clarifies that the webhooks are scoped to the job's events. It adds a bit of semantic flavor but does not substantially expand what the schema already communicates.

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 specific action ('List') and resource ('webhooks') scoped to 'this job's events'. This clearly defines the purpose and differentiates it from the global `hires_list_webhooks` or webhook mutation tools, as the job-scoping is immediately obvious.

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 provides no explicit guidance on when to use vs. the global `hires_list_webhooks` or any other alternative. It neither names a sibling, explains the use case boundary, nor mentions when to avoid using it. The sentence implies job-scoped use, but the agent is left to infer the selection entirely.

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