Cloud Webhook Manage Tool

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

Annotations are empty, so the description fully bears the burden. It clearly discloses HMAC signing, retry with exponential backoff up to 24h, secret shown only on create, immediate invalidation on secret update, and cancellation of in-flight deliveries on delete. No contradictions with annotations.

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 well-structured with a clear paragraph explaining the core purpose followed by a bullet list of actions. It is front-loaded with key information and contains no unnecessary sentences, making it efficient and easy to parse.

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's complexity (9 parameters, multiple actions, no output schema), the description covers behavioral traits well (signatures, retries, secret handling). However, it lacks details on output format for list/get and does not mention default values or optional parameters like deadline_ms, which are covered in schema but not in description.

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%, but the description adds value by associating parameters with actions (e.g., 'create — url, events[], secret'). It explains secret behavior beyond schema, such as 'show once' and 'immediately invalidated'. This enhances understanding beyond the schema descriptions.

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 it manages outbound webhook endpoints and lists all available actions (list, get, create, update, delete). It specifies the resource and actions, and the name 'webhook_manage' aligns with its purpose, distinguishing it from sibling tools that manage other resources.

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 lists actions but does not explicitly state when to use this tool versus alternatives or provide prerequisites (e.g., required permissions). Usage context is implied through the actions, but no when-not-to-use or alternative tool references are given.

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