get_filepath

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, what state is read, whether it depends on an open file, or what it returns. A getter likely has no side effects, but the agent cannot confirm this from the description.

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 one line but that shortness is under-specification, not conciseness. It communicates exactly zero information beyond the tool's own name, wasting the space it occupies.

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?

Even though an output schema exists which may document the return shape, the fundamental subject of the tool is undefined — filepath of what? For a trivial getter the description should at least name the subject (e.g., 'returns the path of the currently open .blend file'). It does not.

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 takes 0 parameters, so the description needs to add no parameter semantics. The baseline of 4 applies since there are simply no arguments to document.

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 'Blender Studio Pro MCP: get_filepath' is a pure tautology that merely prefixes the tool name with the product name. It never states what entity's filepath is returned (current .blend file, import path, etc.), leaving the agent to guess the tool's actual function.

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 whatsoever on when to use this tool versus any of the roughly 200 siblings. No context, no exclusions, no alternative tools named. The agent receives zero navigation help.

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