unlabel_thread

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

No annotations provided. Description states the core behavior (removing labels from all messages in a thread) but does not discuss side effects, error conditions, or required permissions. Adequate but not comprehensive.

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?

Single sentence with no unnecessary words. Directly conveys the tool's action and scope.

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 operation, the description covers the main behavior. However, it omits any mention of return value, error handling, or authentication needs. Nearly complete given tool simplicity.

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 has 4 parameters with 0% description coverage. The description does not explain any parameter beyond its name, leaving account/password purpose unclear. Fails to compensate for the low 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?

Description clearly states the action ('remove one or more labels') and the resource ('every message in a thread'). It distinguishes from sibling tools like 'label_thread' (adds labels) and 'unlabel_message' (removes from single message).

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 vs alternatives (e.g., 'unlabel_message' for single messages). No prerequisites or context provided.

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