get_webhook

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

Provides the HTTP method and path (GET /webhooks/{id}) and states 'Makes no changes', aligning with readOnlyHint=true annotation. Adds endpoint context beyond annotations, though no rate limits or side effects are described.

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?

Contains repetition ('Retrieve a webhook' appears twice) and is not fully concise, but remains short overall. The emoji and path line adds some structure but could be streamlined.

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 read-only retrieval tool with no output schema, the description is minimal. It does not explain return values or fields, leaving the agent without expected output structure. Adequate for simple usage but could be more complete.

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 coverage is 0% and the description does not explain the 'id' parameter beyond implying its necessity. Lacks format, source, or constraints, failing to compensate for the low 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?

Clearly states 'Retrieve a webhook' and 'Fetches data', specifying the verb (retrieve) and resource (webhook). Distinguishes from siblings like create_webhook, delete_webhook, update_webhook, and get_a_list_of_webhooks by focusing on retrieving a single webhook by ID.

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?

Implies usage for retrieving an existing webhook via ID, but lacks explicit when-to-use or when-not-to-use guidance. Does not mention alternatives like get_a_list_of_webhooks for listing.

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