generate_mnemonic

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

No annotations are present, so the description carries the full burden. It accurately describes the core action of generating a new mnemonic but does not add security context (e.g., the phrase is a secret, should be handled carefully, or whether it is returned only once). No contradictions.

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?

Single sentence, front-loaded with the action, and zero extraneous words. Every word contributes to understanding the tool's purpose.

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?

For a simple tool with one optional parameter and no output schema, the description sufficiently conveys the purpose and output (a mnemonic seed phrase). It could add a note about secure handling or related tools, but it is largely complete for the task.

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?

Schema description coverage is 100% with the wordCount parameter already documented via enum and default. The description adds no parameter-specific details, so it remains at the baseline of 3.

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', names the resource 'BIP-39 mnemonic seed phrase', and indicates the purpose 'for wallet creation'. This clearly distinguishes it from sibling tools like import_wallet_from_mnemonic or derive_addresses_from_mnemonic.

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 context (wallet creation) but does not explicitly state when to use this tool vs alternatives such as create_wallet, import_wallet_from_mnemonic, or derive_addresses_from_mnemonic. No exclusions or comparison are given.

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