set_preview_range

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

No annotations are provided, so the description must fully disclose behavioral traits. It reveals nothing about side effects, prerequisites, or output. The agent cannot infer whether this is a read, write, or state-changing operation.

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 short, but this is under-specification rather than conciseness. It does not front-load any useful information; it merely repeats the tool name. A concise description should pack in meaning, not just be brief.

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?

With three parameters, no annotations, and no output schema details, the description is grossly incomplete. Sibling tools like 'set_frame_range' and 'set_pivot_point' give hints that this is a Blender operation, but the description provides no context for correct invocation. An agent cannot safely call this tool.

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 offers no parameter explanation. The schema only shows names like 'start', 'end', and 'enabled' without types or meaning. The description fails to add any semantic insight, leaving the agent to guess what these parameters represent.

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 is just the tool name prefixed with 'Blender Studio Pro MCP:'. It restates the name without adding any information about what 'set_preview_range' actually does. It is a tautology that fails to convey the operation, resource, or scope.

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?

There is no guidance on when to use this tool versus other similar tools such as 'set_frame_range' or 'set_frame'. The description provides no context about the intended workflow or alternatives.

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