free_memory

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

With no annotations provided, the description accurately discloses the main behavior: asking ComfyUI to unload models and free VRAM. However, it omits potential side effects like reloading delays or impact on running workflows, though the action itself is clearly and transparently described.

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 concise sentence, efficiently conveying the tool's purpose without any fluff. Every word earns its place, and the structure is appropriately front-loaded.

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?

The tool is simple with one optional parameter and an output schema, so the description covers the basic function adequately. However, it lacks context about when to use it, potential side effects, or prerequisites like ComfyUI being running, making it not fully complete for an AI agent.

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 input schema has one parameter (unload_models) with 0% description coverage, and the tool description does not mention this parameter at all. The description adds no meaning beyond the parameter's name and default value, failing to compensate for the schema's lack of detail.

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 clearly states the tool's purpose with a specific verb and resource: 'unload models and free VRAM.' It distinguishes this from sibling tools like comfy_stop (which stops ComfyUI) and restart_comfy, making the tool's unique role apparent.

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 implies usage when the user wants to free VRAM by unloading models, but it does not explicitly state when to use this tool versus alternatives or mention any prerequisites. There is no guidance on when not to use it, such as during active workflows.

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