save_blend

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

No annotations are supplied, and the description provides no behavioral information whatsoever. The agent learns nothing about side effects, prerequisites, or return behavior from the description alone, which carries the full burden here.

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 contains no front-loaded useful information—only a repetition of the tool name with a prefix.

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 a file-saving tool with one parameter, no annotations, and a rich set of siblings, the description is completely inadequate. It fails to explain what the filepath refers to, whether it's required, or any constraints on file format or location.

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, but it provides no explanation of the 'filepath' parameter. The schema itself offers no type or description, leaving the agent entirely without information about how to use the parameter.

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 only repeats the tool name with a prefix ('Blender Studio Pro MCP: save_blend') without stating what the tool does. While 'save_blend' suggests saving a Blender file, the description does not explicitly clarify the action or resource, nor does it distinguish the tool from similar file-operation siblings like open_blend or new_blend.

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?

No guidance is provided on when to use this tool or how it differs from alternatives. The description gives no context about file paths, required steps, or relationships with other tools.

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