trello_get_board_labels

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

With no annotations provided, the description carries the full burden. It states the read action and the scope, but does not mention any side effects, authentication requirements (though schema handles that), or response format. The description is truthful but minimal, offering no additional behavioral context beyond what is already obvious from the verb 'Get'.

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 sentence that is front-loaded with the action and resource, and it omits all extraneous details. It is concise and every word contributes meaning.

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 tool's low complexity, the absence of an output schema, and the schema covering all required parameters, the one-sentence description provides sufficient information for an agent to understand what the tool does and what is needed to invoke it. It is complete for this simple read operation.

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?

The input schema already documents all three parameters (apiKey, token, boardId) with 100% coverage, including boardId's pattern and purpose. The description adds no additional parameter-level information beyond referring to a 'specific Trello board,' so baseline 3 is appropriate.

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 ('Get all labels'), the resource ('labels available on a specific Trello board'), and the purpose ('for categorizing cards'). This distinguishes it from sibling tools like trello_get_board_cards or get_board_details, as it specifically targets board labels.

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 phrase 'for categorizing cards' gives some context on when labels would be needed, but it does not explicitly state when to use this tool versus alternatives like get_board_details or explicitly exclude other scenarios. Usage is implied rather than explicitly guided.

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