pack_resources

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 reveals nothing about side effects, required context, or what happens on execution. An agent has no idea if this mutates state, requires specific Blender objects, or has any prerequisites.

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, not conciseness. It provides no useful information and fails to earn its place; a single word repeated with a prefix is not effective.

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 no annotations and no output schema details (though output schema exists, it's not used), the description is entirely inadequate. It doesn't explain what 'pack' means, what resources are affected, or what the tool does. An agent cannot infer correct usage from the name alone.

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?

The tool has zero parameters and the schema coverage is 100% (since there are none). Per the rubric, high schema coverage gives a baseline of 3 even with no parameter info in the description. The description adds no parameter meaning, but there is nothing to add.

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 'Blender Studio Pro MCP: pack_resources' which is essentially the tool name with a prefix. It restates the name without any verb, resource, or action. There is no indication of what packing resources entails, making it a tautology.

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 or how it differs from any of its many siblings (e.g., unpack_resources, import_file, etc.). No context, triggers, or alternatives are mentioned.

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