mail_createWebhookV1

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

Discloses that the secret is returned only in this response and is sent as bearer token. With no annotations, this adds useful behavioral context, but does not cover other important aspects like idempotency, rate limits, or error states.

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?

Two sentences, no unnecessary words. Front-loaded with purpose. Efficient.

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?

Adequate for a creation tool with no output schema. Mentions secret handling, but lacks details on defaults (e.g., status) or what happens after creation. 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 100%, so baseline 3. Description adds no additional meaning to parameters (url, name, events, etc.) beyond their schema descriptions.

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?

Description clearly states the action (Create) and resource (webhook for a given mailbox). It distinguishes from sibling webhook tools (list, get, delete, update, test, regenerate secret) by focusing on creation and secret generation.

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 on when to use this tool versus alternatives like mail_updateWebhookV1 or mail_testWebhookV1. Does not state prerequisites or context.

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