enter_sculpt_mode

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the mode switch but doesn't disclose side effects (e.g., whether the object's current mode is lost, whether the viewport changes, whether the operation is reversible, or whether it requires the object to be a mesh). For a mode-changing operation, this is a significant gap.

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 short sentence with no wasted words. It is front-loaded with the action and resource. However, it is so brief that it sacrifices useful context, but for what it contains, it is concise and clear.

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 tool's simplicity (one parameter, no annotations, no output schema details), the description is minimal but not fully complete. It doesn't explain what 'object' refers to, what constitutes a valid object, or what the expected outcome is beyond the mode switch. An agent would likely need to inspect other tools or make assumptions to use it correctly.

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%, and the description does not explain the 'object' parameter beyond its name. The schema only says it's a required string, leaving the agent to guess whether it's an object name, ID, or path. The description adds no meaning beyond the schema, so it fails to compensate for the low coverage.

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 'Switch an object to sculpt mode' clearly states the action (switch) and the resource (an object to sculpt mode). It is specific enough to distinguish from most siblings, though it doesn't explicitly name a sibling alternative like set_sculpt_brush or remesh. The verb and resource are clear, so it earns a 4 rather than a 5 due to lack of explicit differentiation.

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 gives no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., object must be a mesh), what happens if the object is not sculptable, or when one might prefer set_sculpt_brush or other sculpt-related tools. The context is implied by the name and description, but no explicit usage guidance is provided.

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