Render GPU Allocation Dashboard (PNG)

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

No annotations are provided, so the description carries full burden. It states the tool renders a PNG dashboard, implying a read-only operation, but does not elaborate on side effects, authentication needs, or performance impacts. The prerequisite is mentioned, but broader behavioral traits are absent.

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?

Two sentences: the first clearly states purpose and output format, the second adds a necessary prerequisite. Every sentence is essential; there is no fluff.

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 parameters, no output schema, and no annotations, the description covers the basic purpose and a prerequisite. However, it does not explain how the output is delivered (e.g., image data vs. URL) or provide any usage examples. It is adequate but not fully complete.

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?

There are no parameters, so schema coverage is 100%. The baseline is 3 per guidelines. The description adds no parameter information because none exist, meeting the baseline.

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 it renders a PNG dashboard comparing GPU extended resources per node versus pod requests. It uses specific verbs ('Render') and resource ('dashboard'), and distinguishes from siblings like 'render_gpu_metrics' and 'render_gpu_sparkline' which serve different visualization purposes.

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 provides a clear prerequisite ('Requires nodes with GPU resources or workloads requesting GPUs'), guiding when to use the tool. While it does not explicitly mention when not to use or list alternatives, the context is sufficient for an agent to decide.

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