remove-label-batch

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

No annotations are provided, and the description does not disclose behavioral traits beyond the basic action. Missing details on side effects, permissions, error handling (e.g., if label not found or some emails fail), or limitations (e.g., batch size). For a mutating batch operation, this is insufficient.

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, efficient sentence with no filler. It is front-loaded and directly conveys the core action and input type.

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?

Given the lack of annotations and output schema, the description is adequate for a simple tool but missing important context for a batch operation. No mention of error handling, partial failures, or performance considerations. Leaves the agent without guidance on edge cases.

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% with basic descriptions for both parameters. The description adds context by specifying that email_ids are 'sequence IDs (from search results)', which clarifies the expected source. However, no additional format or constraints are provided.

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 clearly states the action ('remove a label') from multiple emails, specifies the input ('sequence IDs from search results'), and distinguishes from siblings like 'remove-label' (singular) and 'apply-label-batch' (opposite).

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 explicit guidance on when to use vs alternatives like 'remove-label' (for single email) or 'apply-label-batch' (for adding). Usage is implied by the name and description, but no when-not or alternative recommendations are given.

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