generate

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

No annotations are provided, so the description carries the behavioral disclosure burden. It discloses the default generation mode (with symbols) which is helpful. However, it doesn't disclose output format, whether the result is returned or stored, security caveats (e.g., entropy levels at various lengths), or any side effects. The description conveys useful default behavior but leaves key behavioral questions unanswered.

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 concise sentences with no filler. The default behavior is front-loaded in the first sentence and reinforced with a specific detail in the second. Efficient and to the point, though it could pack in more useful behavioral info without bloating.

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 3-parameter tool with no output schema and no nested objects, this is reasonably complete. The description covers the purpose and default behavior. However, given there's no output schema, the description could have noted what the tool returns (a string password/passphrase), and it could clarify the length-parameter semantics for passphrases (word count vs. character count). Adequate but not comprehensive.

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%, so all three parameters are already documented in the schema. The description adds minimal meaning: it mentions the default (symbols) which relates to noSymbols, but doesn't connect the parameters to use cases (e.g., that diceware is for memorability, length means words when diceware is true). The description provides only marginal value above the schema's existing parameter descriptions.

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?

Description states a clear verb+resource ('generate a secure password or passphrase') and adds a default behavior detail (strong password with symbols). While it doesn't explicitly compare against siblings, 'generate' is distinctively a creation action versus the other listed tools (status, list, sync, etc.). Purpose is specific but lacks explicit differentiation from a potential overlapping tool like 'create'.

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 usage for generating passwords/passphrases but provides no explicit when-to-use guidance, no exclusions, and no mention of alternatives. It indicates a 'by default' behavior which gives some context for default invocation, but doesn't clarify when one would use diceware versus symbol-based generation or when to prefer this over a 'create' tool.

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