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

No annotations are provided, so the description bears full responsibility. It states 'cryptographically random,' which is a key behavioral trait, but does not disclose other aspects like performance, permissions, or handling of invalid parameter combinations (e.g., all flags false).

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 that are front-loaded: the first states the core purpose, the second adds essential details. No unnecessary words.

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 6 parameters and no output schema, the description lacks information on return format (the generated password as a string). It also does not explain edge cases like conflicting flags or how exclude_ambiguous works beyond the schema's brief description.

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 only 17% (only exclude_ambiguous has a description). The description adds value by explaining that the boolean flags enable character types and defaults are all on, and length range 4-256. However, it does not detail each parameter beyond what is obvious from property names.

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 clearly states the tool generates a cryptographically random password. It specifies the character types (lowercase, uppercase, digits, symbols) and length range (4-256), making the purpose unambiguous. It distinguishes from the sibling 'strength' by focusing on generation rather than analysis.

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 (generating passwords) but provides no explicit guidance on when to use this tool versus the sibling 'strength' or when not to use it. No alternatives or exclusions are mentioned.

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