create_settings_notifications_webhook

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

Annotations already declare idempotentHint=true and destructiveHint=false, so the description only needs to add context, and it does clarify the operation is an update rather than a creation. It adds a useful instruction to consult the GET/schema endpoint, but it does not disclose auth requirements, which specific webhook fields are affected, or what response is returned.

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 short and front-loaded with the operation and resource, and it avoids re-stating the schema's types. The endpoint path adds a little redundant context but is not significant waste.

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 an opaque-body settings update, the pointer to GET/schema plus output schema availability covers the main data needs. However, there is no guidance on when to use this instead of the many sibling notification-setting tools, and the create/update naming inconsistency is left unresolved.

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?

With schema coverage at 0% and the single body parameter being an open object (additionalProperties:true), the description compensates by directing the agent to read the matching GET or /schema endpoint to discover expected fields. This is essential, actionable guidance, though it does not list concrete field names or value formats.

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?

States a clear verb ('Update') and resource ('webhook notification settings'), so an agent can tell this is a write operation on notification settings. It does not explicitly differentiate from sibling tools like create_settings_notifications_webhook_test or list_settings_notifications_webhook, and the 'create' in the name conflicts with 'Update' in the description.

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 when-to-use or alternative routing is provided; the description never mentions sibling tools or cases where another notification tool should be used. The instruction to read the matching GET or /schema endpoint is a prerequisite for building the payload, not selection guidance.

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