Channel Webhook

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

Annotations already disclose readOnly=false, idempotent=false, and destructive=false. The description adds that the payload is delivered 'for processing,' implying downstream side effects, but it does not elaborate on what processing entails, delivery guarantees, or error behavior. This is moderate added context beyond annotations, not rich disclosure.

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 a single, front-loaded sentence that states the verb and object immediately. There is no wasted wording or redundant detail, which makes it maximally concise for a simple tool.

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 low-complexity tool with complete schema coverage and useful annotations, the description is mostly sufficient. The main gap is not explaining what 'processing' means or what the caller should expect in return, but the core invocation intent is clear and the tool is small enough that this does not severely impede usage.

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 both 'payload' and 'channel_id' are already documented. The description does not add meaning beyond the schema; it merely echoes the concept of a webhook payload. Baseline 3 is appropriate given full schema coverage.

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 uses a specific verb ('deliver') with a clear resource ('inbound messaging-platform webhook payload') and destination ('to a channel for processing'). It distinguishes itself from sibling channel tools (create/list/delete) and webhook tools by focusing on inbound payload delivery for processing.

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 implies usage: you would call this when you have a messaging-platform webhook payload to route to a channel. However, it does not explicitly state when to use this over alternatives (e.g., KB sync webhook tools) or exclude other cases, so the guidance is only implicit.

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