layout_set_flex_properties

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

No annotations are provided, so the description must carry the full burden. It states only that the tool sets properties, but does not disclose any behavioral traits (e.g., destructive effects, required permissions, error conditions, or side effects). This is insufficient.

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 very short (one sentence) but lacks essential context. It is concise but not informative; conciseness should not come at the expense of completeness.

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 presence of sibling tools for individual properties, the description should clarify the advantage of using this combined tool. Without an output schema, the description should at least hint at what the tool returns. It is incomplete for the tool's complexity.

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 100% with descriptions for all parameters. The description does not add extra meaning beyond the schema (e.g., how to obtain the objectId or the effect of fit/factor). Baseline 3 is appropriate as the schema does the heavy lifting.

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 is essentially a paraphrase of the tool name ('Set multiple flex properties of a flex child widget'), providing no additional insight. It does not differentiate from sibling tools like layout_set_flex_factor and layout_set_flex_fit, which are more specific. This fails the 'specific verb+resource' standard.

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 given on when to use this tool versus the individual property setters. The description offers no context about use cases, when to prefer batch updates, or when to use alternatives.

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