setup_control

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only lists configurable aspects without stating whether it overwrites existing settings, requires a Control node, or how invalid values are handled. For a mutating tool, this is a notable gap.

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, well-structured sentence. It leads with the action and resource, then lists properties without any filler. Every word contributes value.

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?

Despite a rich schema with enums, the tool has 9 parameters, nested objects, no output schema, and no annotations. The description is too sparse to fully support autonomous invocation: it omits prerequisites (e.g., node must be a Control), side effects, and how properties interact. It is inadequate for this complexity level.

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 description coverage is 0%, so the description must compensate. It does map high-level concepts to parameters (e.g., 'grow directions' to grow_h/grow_v), but it doesn't explain nuances like the string vs object form of min_size or the meaning of size flag values. Partial compensation but insufficient for full clarity.

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 'Configure a Control's layout' and enumerates specific properties (anchor preset, minimum size, size flags, grow directions, margins, separation). This verb+resource+scope is specific and distinguishes it from generic setters like batch_set_property and the narrower set_anchor_preset.

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 usage for layout configuration but provides no explicit guidance on when to use it versus alternatives such as set_anchor_preset or individual property updates. It gives clear context but no exclusions or alternative recommendations, so it earns a mid-range score.

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