setWebhook

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only states the basic purpose. It does not mention that calling this overwrites any existing webhook, that an empty URL also removes the webhook, or that webhook mode conflicts with getUpdates polling.

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 two sentences with no filler. The main purpose is front-loaded, and the sibling alternative is stated economically.

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?

For a webhook configuration tool with no annotations and no output schema, the description is too thin. It omits important lifecycle context such as replacing an existing webhook, verification via getWebhookInfo, and the interaction with getUpdates.

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 already fully documents all seven parameters. The description adds no extra parameter semantics, which is acceptable under the baseline.

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 states a specific action ('Specify a URL') and resource ('receive incoming updates via webhook'), making the tool's purpose immediately clear. It also distinguishes itself from deleteWebhook by explicitly noting that removal is handled there.

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 gives clear context: use this tool when you want to receive updates via webhook rather than polling. It names deleteWebhook as the alternative for removal, though it does not explicitly contrast with getUpdates or other update-delivery options.

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