generate_password

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

The 'cryptographically secure' phrasing adds a meaningful behavioral guarantee beyond the annotations. The readOnlyHint and openWorldHint annotations already cover safety and statefulness, so the description does not need to repeat those. It could add more detail about randomness source or output format, but nothing here contradicts the 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 one concise sentence with no filler. It front-loads the core purpose and then briefly summarizes configuration options, earning a top score for efficiency and structure.

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 rich parameter schema, the description provides enough context for correct invocation. The only notable gap is the output shape: it does not state whether a single password or an array is returned, especially since 'count' can exceed 1. This is a minor omission for a password-generation 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?

Schema description coverage is 100%, so the parameters are already well documented. The description's mention of 'length, character sets, and exclusions' paraphrases the schema but adds no new semantic detail. A baseline of 3 is appropriate because the schema carries the parameter-documentation burden.

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 states a specific verb and resource: 'Generate cryptographically secure random passwords.' It clearly distinguishes this from sibling generate_* tools such as generate_hash, generate_uuid, and generate_lorem by naming passwords as the output. The mention of configurability adds useful scope without ambiguity.

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 intended use is strongly implied by the description: use this when a random password is needed. However, it gives no explicit guidance about when not to use it or which alternative tools to prefer, even though many sibling generation tools exist. This makes usage guidance adequate but not explicit.

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