etabs_set_grid_system

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

Annotations provide readOnlyHint=false and destructiveHint=false, but the description does not clarify behavioral traits such as whether it overwrites existing grids, requires model initialization, or has side effects. The description adds minimal behavioral context beyond the action itself.

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 well-structured with a clear purpose statement, followed by parameter descriptions and a return value note. It is concise and front-loaded, with no unnecessary information.

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?

The description covers purpose, parameters, and return value adequately. Given the tool's moderate complexity and the presence of an output schema, it is mostly complete, though it could mention behavior on existing grid systems.

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 description fully explains each parameter in the docstring, including default behavior for optional grid IDs. Since the schema has 0% coverage for parameter descriptions, this adds significant 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 explicitly states 'Define or modify a Cartesian grid system,' which clearly identifies the action and resource. It distinguishes from siblings like etabs_get_grid_systems, which reads grid systems.

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 on when to use this tool versus alternatives (e.g., etabs_get_grid_systems). The description lacks context on prerequisites or scenarios where defining/modifying a grid system is appropriate.

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