mail_testWebhookV1

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

Discloses rate limiting, but lacks detail on side effects (none expected) or return format. Since no annotations exist, description carries full burden; it is adequate but minimal.

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 short sentences, no fluff. Could be slightly restructured for readability (e.g., bullet points), but remains effective and concise.

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 simple test tool with one parameter and no output schema, the description covers core behavior and constraint (rate limit). Implicitly assumes webhook exists, but acceptable.

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?

Single parameter webhookId is already described in the schema. Description adds no extra clarification beyond the existing schema documentation, meeting baseline for 100% 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?

Description clearly states the action: send a test delivery to a webhook URL and return the result. The verb 'test' distinguishes it from creation or deletion tools like mail_createWebhook or mail_deleteWebhook.

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 explicit guidance on when to use this tool versus alternatives. Mentions rate limiting but does not specify prerequisites or scenarios (e.g., only after creating a webhook).

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