activate_webhook

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

No annotations present, and description provides minimal behavioral context. It does not explain what 'activate' means in terms of state changes, permissions, or side effects.

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?

Description is a single, focused sentence with no waste. However, it is perhaps too brief to be fully informative, but it earns points for being concise.

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 output schema and minimal description, the tool is incomplete. It lacks details about return values, side effects, or whether the webhook must exist beforehand.

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 already provides descriptions for both parameters (list_id, webhook_id) with 100% coverage. Description adds no extra meaning beyond the schema.

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?

Description uses specific verb 'Activate' and resource 'webhook' with qualifier 'for a subscriber list'. It clearly distinguishes from sibling tools like create_webhook, deactivate_webhook, and test_webhook.

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 on when to use this tool versus alternatives like deactivate_webhook or test_webhook. No prerequisites or conditions provided.

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