create_sketch_entities

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

With no annotations, the description carries the full burden and it does disclose that the tool mutates by creating entities and that it verifies the snapshot delta. However, it does not mention document-open requirements, persistence behavior, error handling, or what happens when verification fails, leaving notable behavioral gaps.

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 front-loaded sentence with no filler. Every phrase contributes meaning, and it clearly leads with the primary action and resource.

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?

For a complex 13-parameter tool with no output schema and no annotations, this description is far too thin. It omits how entities are structured, how constraints and dimensions are supplied, whether a new sketch is created, what the return value is, and what 'verify snapshot delta' implies for the caller.

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 13 parameters, but it adds almost nothing specific. 'Several' hints at the array nature of entities and 'target sketch' hints at a sketch context, but there is no explanation of entities, constraints, dimensions, flags, or the create_new_sketch/sketch_ref relationship.

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 ('create') and identifies a concrete resource ('several 2D sketch entities in one target sketch'), clearly distinguishing it from the singular create_sketch_* tools among the siblings. The additional mention of 'verify the snapshot delta' establishes a distinct secondary purpose.

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 'several 2D sketch entities in one target sketch' clearly communicates the intended batching use case versus single-entity creation alternatives. It does not explicitly state exclusions or mention when to prefer sibling tools, but the context is unambiguous enough for selection.

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