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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states this is a read operation ('Get details'), which implies non-destructive behavior, but doesn't cover aspects like authentication requirements, error handling (e.g., for invalid IDs), rate limits, or response format. This leaves significant gaps for a tool with no annotation coverage.

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, efficient sentence that front-loads the core action ('Get details') without unnecessary words. Every part of the sentence contributes directly to understanding the tool's purpose.

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 no annotations and no output schema, the description is incomplete for a tool that retrieves data. It doesn't explain what details are returned (e.g., webhook configuration, status), error scenarios, or behavioral traits like idempotency. For a read operation with no structured support, more context is needed.

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%, with the single parameter 'webhookId' documented in the schema. The description adds minimal value by implying the parameter is used to identify a specific webhook, but doesn't provide additional context like ID format or sourcing. This meets the baseline for high schema coverage.

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 ('Get details') and resource ('a specific webhook by ID'), making the purpose unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'list_webhooks' or 'create_webhook', which would require mentioning it retrieves a single webhook rather than listing or creating one.

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 guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'list_webhooks' for multiple webhooks or 'update_webhook' for modifications, nor does it specify prerequisites such as needing an existing webhook ID.

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