webhook_settings

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

No annotations are provided, so the description must fully disclose behavior. It merely says 'Open your settings', implying a read-only navigation, but does not confirm safety, side effects, authentication needs, or what happens after opening. The agent learns little about the tool's behavior.

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 a single sentence and concise, but it is under-specified. For a tool with one parameter and no annotations, more detail is needed to justify its brevity. It earns its place but lacks completeness.

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?

Given the tool has one parameter, no annotations, and an output schema (not shown), the description should contextualize the output and behavior. It does not address what the user sees or how to interact, leaving the agent with insufficient information to invoke it correctly.

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?

The schema has one optional parameter 'user_id' with no description coverage (0%). The description does not mention or explain this parameter, so it adds zero value beyond the schema. The agent cannot infer its purpose or default behavior.

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 clearly states 'Open your settings: Gmail connection status and webhook subscriptions', identifying both the action ('Open') and the resource ('settings'). It distinguishes the tool from siblings that modify subscriptions or perform other actions, though it does not specify what 'open' entails beyond viewing.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, scenarios, or contexts where opening settings is appropriate, leaving the agent without decision support.

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