create_settings_notifications_webpush

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

Annotations already indicate readOnly=false, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds a useful behavioral note that the body schema is open and the agent should consult a GET or /schema endpoint, but it does not explain update semantics such as whether this replaces or merges existing settings.

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 compact and front-loaded, stating the action, the resource, the HTTP route, and the argument handling in a few lines. No sentence is wasted, and the external-field-discovery instruction earns its place given the open body schema.

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 tool with an open body schema and many closely related siblings, this description is minimally adequate because it points to the GET/schema endpoints. However, it does not distinguish this tool from the webpush test tool or other notification settings tools, and it does not clarify whether 'create' in the name means update, which leaves an agent needing additional context.

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%: the only parameter 'body' is an open object with no property descriptions. The description merely calls it a 'Request payload' and redirects the agent to the GET or /schema endpoint, which is a workaround rather than actual parameter semantics. It does not tell the agent what fields are relevant or how to structure them.

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 states a specific action ('Update') and resource ('Web Push notification settings'), but the tool name says 'create_' while the description says 'Update', creating a mild inconsistency. It does not differentiate this tool from the many sibling notification-settings tools, especially 'create_settings_notifications_webpush_test' or 'list_settings_notifications_webpush'.

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 offers no guidance on when to use this tool versus alternatives such as the webpush test endpoint or other notification channel settings. The only procedural hint is 'Read the matching GET or the /schema endpoint first', but that is about discovering fields, not about choosing between competing sibling tools.

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