create_webhook

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

No annotations present; description carries full burden. Mentions POST behavior and event subscription but lacks details on security (HTTPS required), rate limits, webhook verification, or what happens on failure. Could be more transparent.

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?

Two sentences, front-loaded with purpose. Every sentence adds value. No wasted words.

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?

Adequate for a simple creation tool with two parameters. Covers what it does and how to subscribe. Could mention return value (e.g., webhook ID) but not critical. No output schema, so description is sufficient.

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 100%, baseline 3. Description adds context that omitting event_types subscribes to all events, which is useful beyond schema. For url, description restates 'HTTPS endpoint' but no new meaning.

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?

Clearly states the tool creates a webhook that POSTs to an HTTPS endpoint on events. Examples provided (e.g., post published). Doesn't explicitly differentiate from sibling webhook tools but the action is clear.

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?

No explicit when-to-use or when-not-to-use. Implies usage by describing subscription options (specific or all events). No reference to alternatives like update_webhook or delete_webhook.

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