set_parameter_layout

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

No annotations provided, so description carries full burden. It discloses writes to NumberOfRows+NumberOfColumns, rewrites CellDefinitions, strict permutation check, auto-creates block, idempotency, and return values.

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?

Front-loaded with purpose, each sentence adds value. No wasted words. Structured to explain behavior, constraints, and relationships efficiently.

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?

With 4 parameters, no output schema, and no annotations, description covers behavior, return values, and differentiation. Fully sufficient for correct invocation.

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?

Schema coverage is 0%, but description explains each parameter: path implied, rows/columns counts, and parameter_order with permutation and layout formula. Adds meaning beyond schema types.

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 it authors ReportParametersLayout/GridLayoutDefinition with specific verb 'Author' and resource. It explains grid layout behavior and distinguishes from sibling tools reorder_parameters and sync_parameter_layout.

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?

Explicitly mentions when to use this tool versus alternatives (reorder_parameters for declaration order, sync_parameter_layout for gap-filling). Also notes idempotency and auto-creation of layout block.

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