set_attributes

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

No annotations exist, so the description must disclose behaviors. It only states that the tool sets attributes and participates in undo, omitting important traits like whether it requires specific permissions, if changes are reversible, how existing attributes are handled, or any side effects.

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 extremely concise at two sentences, but the brevity comes at the cost of missing critical information needed for tool invocation. It is not verbose, but it is under-informative.

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, the description fails to explain the return value or the behavior beyond a basic set operation. For a tool with three required parameters and no parameter documentation, the description is insufficient for effective use.

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%, yet the description adds no explanation of the three parameters (uuid, kind, attributes). It does not clarify what 'kind' means or how to structure the attributes array, leaving the agent to rely solely on 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 clearly states the tool sets one or more attributes on an element, which is a specific verb-resource pair. It distinguishes from sibling tool get_attributes by focusing on setting versus getting.

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 mentions 'Participates in undo' but provides no explicit guidance on when to use this tool versus alternatives, such as when to prefer assign_layer or create_* tools. No exclusion criteria or context are given.

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