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

The only behavioral note is that the path is discarded, but there is no mention of side effects, network access, or error behavior. With no annotations, this is insufficient for full transparency.

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 concise with a clear structure. It does not waste words, though it might benefit from a bit more explanatory detail.

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 lacks an output schema and annotations, and the description does not explain what result is produced or how the parameters relate to the input URL. This makes it incomplete for a caller to use effectively.

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?

Although every parameter has a schema description, they are generic placeholders (e.g., 'City name for a public weather hint') that do not relate to parsing a Figma URL. The descriptions add no meaningful semantic value and are misleading.

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 a specific action ('Parse') on a specific resource ('Figma file URL'), distinguishing it from sibling URL tools. However, it lacks detail about what the parsed output contains.

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 versus alternatives like normalize-url or domain-shape. The description gives no context for appropriate use cases.

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