Create a Teamline webhook

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

Beyond the annotations, it discloses a key architectural caveat: the server registers the URL, but the MCP stdio process will not receive Teamline POSTs. It also states the API token is read only from TEAMLINE_API_KEY and that only tasks_completed is official, all useful behavioral context.

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?

Four short sentences, all substantive, with the core registration action and event constraint front-loaded. The required/optional note slightly repeats schema information, but the architecture and auth notes earn their place.

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 three-parameter creation tool with annotations and full schema coverage, the description supplies the necessary auth source, event restriction, and server-side behavior. It omits return/error details, but no output schema exists and the missing info is not essential for invoking the tool.

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 coverage is 100%, so the schema already documents all three parameters. The description adds value beyond it by explicitly marking url required and name optional and by constraining event to tasks_completed, which is the main semantic guidance an agent needs.

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 opens with a concrete verb-resource pair ('Register a user-provided URL via webhooks.create') and immediately narrows scope to the only supported event, tasks_completed. This is enough to distinguish it from the remove sibling and from the task tools.

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?

It gives clear context for the create action and the supported event, so an agent can infer when to use it. However, it does not state when not to use it or point to webhooks_remove or another alternative, leaving routing to inference.

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