tokportal_get_webhook_endpoint

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, which inform the agent of safe read-only behavior. The description adds nothing beyond the operation name, but does not contradict annotations. Given the annotation coverage, a score of 3 is appropriate as the description provides minimal additional value.

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 sentence of 4 words, highly concise and front-loaded. However, it is so terse that some useful context (e.g., 'by ID') is omitted. It earns its place but could be slightly more informative without becoming verbose.

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?

With no output schema, the agent has no information about what the response contains. The description does not mention that the tool returns a webhook endpoint object or any prerequisites (e.g., the endpoint must exist). Given the low complexity (1 param, annotations present), the description is incomplete for reliable agent use.

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 (id) with 100% schema description coverage: 'Webhook endpoint ID.' The description 'Get a webhook endpoint' implicitly requires an ID, but adds no extra meaning beyond the schema. Baseline 3 is correct.

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 the verb 'get' and resource 'webhook endpoint', but it does not distinguish from the sibling 'tokportal_list_webhook_endpoints' which retrieves multiple endpoints. The purpose is clear but lacks explicit differentiation, making it adequate but not outstanding.

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_webhook_endpoints (to retrieve all endpoints) or create/update/delete. The agent receives no context for selecting this tool over its siblings.

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