create_webhook

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('Create') but lacks details on permissions required, whether the operation is idempotent, rate limits, error conditions, or what the response includes. This is inadequate for a mutation tool with zero annotation coverage.

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, efficient sentence that front-loads the core action and lists parameters without unnecessary words. Every part earns its place, making it easy to parse quickly.

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 complexity of a 5-parameter mutation tool with no annotations and no output schema, the description is incomplete. It covers basic parameters but misses critical behavioral details (e.g., authentication needs, response format, error handling), making it insufficient for safe and effective tool invocation.

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 description lists parameters (name, url, events, description, secret) and indicates which are optional, adding value beyond the schema's 0% description coverage. However, it doesn't explain parameter meanings (e.g., what 'events' entails, format for 'secret'), leaving gaps in understanding despite compensating somewhat for the schema's lack of 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 the verb ('Create') and resource ('a webhook'), making the purpose immediately understandable. However, it doesn't distinguish this tool from sibling tools like 'update_webhook' or 'delete_webhook' beyond the obvious action difference, missing explicit differentiation about when to create versus update.

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 doesn't mention prerequisites (e.g., needing admin permissions), compare to sibling tools like 'update_webhook' or 'delete_webhook', or specify scenarios for webhook creation, leaving the agent with minimal context for decision-making.

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