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

Annotations already carry the safety profile: readOnlyHint=false, destructiveHint=true, and idempotentHint=true. The description adds the useful detail that the tool returns the created node's UUID, but it does not explain the destructive implications or why it is idempotent. No contradiction exists, but the description contributes limited behavioral context beyond the annotations.

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 entire description is one efficient, front-loaded sentence with no filler. Every phrase adds information: action, resource, document scoping, and return 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?

Given five parameters with zero schema-level descriptions, no output schema, and no explanation of instance_id/operation_id/parent_node_id semantics, the description is not complete enough for an agent to confidently invoke the tool. The concepts of 'explicit document' and 'return UUID' help, but too much operational context is missing.

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 for the five parameters. It weakly maps 'name' via 'named' and 'document_id' via 'explicit document', but it says nothing about instance_id, operation_id, or the optional parent_node_id. This leaves most parameters semantically unexplained.

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 states a specific action ('Create one named paint layer'), identifies the resource ('paint layer'), scopes it to an explicit document, and mentions the return value ('node UUID'). This clearly distinguishes it from sibling creation tools like create_group_layer or create_vector_layer.

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 phrase 'in an explicit document' provides clear context for when to use this tool, implying it targets a specific document rather than an implicit or active one. However, it does not explicitly name alternatives or state when not to use it, so it falls short of a 5.

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