move_cell_up

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states a swap occurs but does not disclose edge cases (e.g., behavior when above cell doesn't exist), error conditions, or any side effects beyond the swap. For a mutation tool, this lacks necessary 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, efficient sentence with no unnecessary words. However, it might be slightly under-specified, sacrificing clarity for brevity, so it doesn't earn a 5.

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 incomplete for a mutation tool. It omits prerequisites, edge cases, and any behavioral context. The presence of move_cell_down as a sibling creates a pair, but the description doesn't explain how this tool fits into that context.

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?

With schema description coverage at 0%, the description needed to explain the parameters. It does not mention cell_id or buffer_id at all, leaving their meanings to be inferred from names alone. The description adds no 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 'Swap a cell with the one above it' uses a specific verb ('swap') and resource ('cell'), and clearly distinguishes this from the sibling tool move_cell_down by specifying direction ('with the one above it'). This leaves no ambiguity about the tool's function.

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 like move_cell_down, nor are any prerequisites or conditions (e.g., what happens if the cell is already at the top) mentioned. The description merely states the operation without context.

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