list_board_labels

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

The description only states the action and return type, without annotating read-only or destructive behavior. No annotations are provided, so the description should fill the gap. It fails to disclose whether the operation has side effects, requires authentication, or has rate limits beyond what is obvious.

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 extremely concise—two sentences that directly state the purpose and output. No unnecessary words or redundancy.

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 simplicity and the presence of an output schema, the description is adequate but not complete. It lacks details on board_id validation, error conditions, and permission requirements, leaving minor gaps for an agent.

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 has 0% description coverage, and the description does not explain the board_id parameter beyond its implicit role. Format, constraints, or examples are absent, so the description adds minimal semantic value beyond the schema.

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 tool lists all labels on a Trello board and specifies the return format (JSON array with id, name, color). It distinctly describes a specific operation on a specific resource, differentiating it from sibling tools like list_boards or list_card_checklists.

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., create_label, add_label_to_card). There is no mention of prerequisites, context, or exclusions, leaving the agent without decision support for selection.

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