C2.9/5.0
Behavior2/5

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

With no annotations, the description carries the full burden but only hints at batching via 'single operation.' It does not disclose whether the batch is atomic, what happens on partial failure, required permissions, or whether referenced boards/looks must pre-exist.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single short sentence that is front-loaded with the verb and resource, with no filler. It is efficient, though arguably terse enough to leave necessary context unstated.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a bulk mutation accepting an array of nested objects with required board/look references, the description omits failure semantics, ordering, and return behavior, and no output schema or annotations compensate. It is materially under-specified for the tool's complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the nested button object's fields are already documented in the schema. The description adds no meaning beyond the single 'buttons' array, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Create') and resource ('buttons') and clarifies the bulk nature with 'multiple buttons in a single operation,' which distinguishes it from single-button operations. However, it does not differentiate from close siblings such as create_look_board_with_buttons or bulk_update_look_board_buttons.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus create_look_board_with_buttons (for a new board) or add_look_to_board, nor any prerequisite such as the look board existing. The agent must infer usage entirely from the name and siblings.

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