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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'secure BIP39' but doesn't explain what this means in practice (e.g., entropy source, word count, format of the output, or any failure behavior). This lack of detail is a significant gap for a tool that generates sensitive data.

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 that immediately conveys the core functionality. It is efficiently front-loaded with the verb and resource, with no wasted words or filler.

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 (zero parameters, output schema available), and the description adequately covers the primary action. It doesn't mention output details like word count or format, but given the output schema exists and the tool's simplicity, the description is reasonably complete for an agent to invoke it correctly.

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, so the baseline for parameter semantics is 4. The description doesn't need to explain any parameters, but it also gives no hints about how the mnemonic is formatted or returned, which is acceptable given the schema is empty.

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 uses the specific verb 'Generate' and identifies the resource as 'a secure BIP39 mnemonic phrase,' making the tool's purpose unambiguous. It clearly distinguishes itself from the sibling tools, which are all unrelated to mnemonic generation.

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 does not explicitly state when to use this tool versus alternatives, but the siblings are clearly in different domains, so the implied usage is straightforward. There is no exclusion criteria or alternative named, leaving the guideline at a basic level.

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