move_cell_down

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

No annotations are provided, so the description carries the full burden. It clearly states the swap action, but does not disclose edge-case behaviors (e.g., what happens if the cell is already at the bottom) or side effects beyond the swap. The operation is simple and the description covers its primary behavior, but lacks deeper transparency.

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, concise sentence with no unnecessary words. It is front-loaded and directly states the action, earning a perfect score for brevity and clarity.

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?

As a mutation tool with no annotations, no output schema, and minimal parameter documentation, the description is sparse. It does not mention return values, edge cases, or any constraints, leaving the agent with an incomplete picture for a tool that involves a destructive or rearrange 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 schema description coverage is 0%, and the description does not explain the parameters 'cell_id' or 'buffer_id' at all. The property names provide some hint, but the description adds no meaning beyond the schema, failing to compensate for the low 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?

The description 'Swap a cell with the one below it' uses a specific verb ('swap') and resource ('cell'), clearly distinguishing the tool from its sibling 'move_cell_up' which swaps with the cell above. It unambiguously states what the tool does.

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 description implies when to use the tool (when you need to move a cell down) but provides no explicit context about when not to use it or alternatives like 'move_cell_up'. The sibling tools list offers hints, but the description itself lacks direct guidance.

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