set_slot_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 only states 'set layout slot properties' without disclosing side effects, required permissions, whether changes are reversible, or what happens if the slot is invalid. The description adds minimal behavioral context beyond the obvious mutation.

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 sentence with no redundant words. However, it could benefit from a bit more structure, such as listing the required parameters or mentioning that the output schema provides result details.

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 having an output schema (context signal), the description does not mention the return value or error cases. For a mutation tool with no annotations and three required parameters, the description should specify what happens on success/failure or any constraints, which it does not.

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% and the description only lists example property keys (anchors, offsets, padding, alignment) without explaining the format, constraints, or how to structure the 'properties' object. For a free-form object parameter, this is insufficient guidance.

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 uses a specific verb ('Set') and resource ('layout slot properties') and lists example properties like anchors, offsets, padding, alignment, etc. This clearly distinguishes it from the sibling tool 'get_slot_properties' which reads slot properties.

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 vs alternatives (e.g., when the parent widget is not set up or when to use 'set_widget_properties' instead). There is no mention of prerequisites, context, or when not to use it.

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