generate_random_password

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

With no annotations, the description carries the full burden of behavioral disclosure, and it discloses almost nothing. For a security-sensitive generation tool, there is no mention of whether the password is cryptographically random, what the default character set is, what happens if no options are specified, or whether ambiguous characters are avoided. The return format is also undisclosed and there is no output schema to compensate.

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 single sentence is maximally efficient with zero filler words and states the core purpose immediately. It loses a point only because such brevity veers toward under-specification rather than deliberate conciseness, though the schema picks up the slack for parameter documentation.

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 has four optional parameters, no output schema, and no annotations, yet the description explains none of the surrounding behavior: default output, interaction of the boolean flags, or the form of the returned password. For a security-related tool especially, an agent lacks enough information to invoke it with confidence without making assumptions.

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 baseline of 3 applies. The description itself adds no parameter-level meaning beyond the schema, but the schema already documents each parameter's purpose. Missing context like defaults and interaction between toggles (e.g., behavior when all flags are false) would be valuable but is not required at this coverage level.

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 clear verb and resource ('Generate a random password') with no ambiguity about the operation. However, it does not differentiate from the sibling tool 'generate_passphrase', which serves a closely related purpose, so an agent could not tell which to choose from the description alone.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention the configurable options (length, numbers, symbols, uppercase), when to prefer this over generate_passphrase, or any constraints for safe use. The agent is left to infer everything from the schema.

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