removeContactFromList

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

The description merely states 'remove', implying mutation, but with no annotations provided, it fails to disclose details such as side effects, irreversibility, or error handling (e.g., contact not found).

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, concise sentence with no extraneous information. However, it could be expanded slightly to cover parameters without losing conciseness.

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 simple removal tool with two required parameters and no output schema, the description provides the core purpose but omits details like expected parameter formats or return behavior. Adequate but not thorough.

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?

With 0% schema description coverage, the description must add meaning. It implicitly maps 'contact' to the email parameter and 'contact list' to listName, but does not explicitly link to the schema fields, reducing clarity.

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 the action ('Remove') and the resource ('a particular contact from the contact list'), clearly distinguishing from sibling add tools. However, it does not explicitly reference the 'listName' parameter, leaving room for ambiguity about which list.

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 (e.g., addContactToList, unsubscribeContact). The context of sibling tools is not leveraged to clarify appropriate use cases.

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