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 only mentions that the tool is browser-based and creates hanko seals, but does not disclose output format, limitations, download behavior, or any side effects. This is insufficient for a generation tool with no annotations.

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—two brief phrases—with the main action front-loaded. Both sentences earn their place: the first states the core function, the second clarifies the platform. No wasted words.

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 the tool's simplicity (0 parameters, no output schema, no annotations), the description covers the essentials needed for an agent to invoke it correctly: what it creates and that it runs in a browser. It could mention the output form (e.g., image file) but is otherwise complete for this low-complexity tool.

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 input schema is empty. The description does not need to elaborate on parameters, and the baseline for 0-parameter tools is 4. The mention of seal types is not param-related, which is fine.

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 function with a specific verb ('Create') and resource ('digital hanko seals'), and expands on scope with examples (personal, corporate, date stamps). It distinguishes itself from sibling tools like pdf-stamper or certificate-maker by naming the unique domain of hanko seals.

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 use for creating digital hanko seals, but provides no explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. It's clear enough from the purpose but lacks explicit usage context.

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