get_webhook

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

With no annotations, the description must carry the behavioral burden. It clearly states the action (get) but does not explicitly disclose that it is read-only, nor does it mention potential error responses (e.g., 404 if id not found) or return format. For a simple get, the basic behavior is implied, but it lacks the explicitness expected when annotations are absent.

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 a single, front-loaded sentence with zero redundancy. It efficiently states the action and scope without elaboration, making it highly scannable for an agent.

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 exactly one parameter and no output schema, this description is largely sufficient. It tells the agent what the tool does and the key input. However, it could have briefly mentioned that this is the read counterpart to create/update/delete webhook tools, which would fully contextualize it. Still, given the simplicity, it is complete enough for correct invocation.

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 description references the 'id' parameter but adds no meaning beyond the schema. It does not clarify that the id is the unique identifier of the webhook endpoint, nor does it offer any context about value formatting or constraints. With schema description coverage at 0%, the description should have compensated, but it merely restates the parameter name.

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 'Get a webhook endpoint by id' uses a specific verb (get) and resource (webhook endpoint) with a clear scope (by id). It unambiguously distinguishes from siblings like list_webhooks (retrieves all) and create_webhook (creates) because it specifies fetching a single endpoint by identifier.

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 is provided on when to use this tool versus alternatives such as list_webhooks or test_webhook. It does not mention exclusions or conditions that would steer an agent to a different tool, leaving the decision entirely to inference from the name.

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