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

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: the tool returns a webhook with a signing secret that's shown only once, implying a security-critical, non-repeatable operation. However, it lacks details on permissions, rate limits, error handling, or what happens if the URL is invalid.

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 appropriately sized with two sentences. The first sentence states the purpose, and the second adds critical behavioral context about the signing secret. It's front-loaded with the main action, though it could be slightly more structured (e.g., explicitly listing key behaviors).

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 no annotations and no output schema, the description is moderately complete. It covers the creation purpose and a key behavioral trait (one-time secret), but lacks details on return values beyond 'webhook', error conditions, or integration context. For a mutation tool with security implications, more guidance would be helpful.

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 fully documents both parameters (url and events). The description adds no parameter-specific information beyond what's in the schema, such as URL format constraints or event semantics. Baseline 3 is appropriate when schema does the heavy lifting.

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 'webhook' with the purpose 'to receive notifications'. It distinguishes from siblings like webhook_delete, webhook_update, and webhooks_list by specifying creation rather than deletion, modification, or listing. However, it doesn't explicitly differentiate from other creation tools like barevalue_submit or barevalue_upload.

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., account setup), compare to siblings like webhook_update for modifications, or specify use cases beyond generic notifications. The agent must infer usage from the tool name alone.

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