tokportal_update_webhook_endpoint

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

The description adds minimal behavioral context beyond the annotations. Annotations indicate it is not read-only and not destructive, which aligns with 'update', but nothing is said about whether it performs a full replacement or partial patch, expected side effects, or response behavior. The description could elaborate on the mutation semantics.

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 extremely concise (two words of substance). While concise, it fails to structure any additional useful information. It earns a 3 because it is not verbose, but it could be improved by adding a brief sentence about the body's partial update behavior or idempotency.

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 has three parameters including a nested object and no output schema, the description is incomplete. It does not mention what the response returns, that the 'body' fields are optional for partial updates, or the purpose of the idempotency key. More context is needed for an AI agent to use this tool correctly.

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 baseline is 3. The description itself adds no extra parameter meaning beyond what the schema already provides (e.g., that 'body' is a JSON object with optional fields).

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 action ('Update') and resource ('webhook endpoint'), which is distinct from sibling tools like create or delete. However, it lacks any additional context about scope or partial updates that would elevate it to a 5.

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 guidance is provided on when to use this tool versus alternatives like creating or deleting webhooks. There is no mention of prerequisites, required state (e.g., endpoint must exist), or context for when an update is appropriate.

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