update_webhook

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

Annotations already indicate idempotentHint=true and destructiveHint=false. The description adds the HTTPS requirement and 10-second response time constraint, but does not detail side effects like whether event subscriptions are replaced or appended, or authorization needs.

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 two sentences, succinct and to the point. It front-loads the main action and then provides key constraints. Minor improvement could be omitting 'and more' in favor of referencing the schema for full event list.

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?

With 100% schema coverage and an output schema present, the description sufficiently covers the tool's purpose and a critical timing constraint. It does not explain return values, but the output schema likely does. No missing aspects given the tool's complexity.

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 description coverage is 100%, so the schema already documents all parameters. The tool description repeats the HTTPS requirement mentioned in the schema, but adds no new parameter-level meaning beyond what is in the schema.

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 the verb 'configure' and the resource 'webhook endpoint URL and event subscriptions', with a specific purpose of real-time notifications. It lists example event types, distinguishing it from sibling tools like create_rule or list_packages.

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 implies usage for updating webhook settings but does not explicitly state when to use or not use this tool versus alternatives. No exclusion criteria or alternative tool names are given.

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