estimate_password_strength

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

With no annotations provided, the description carries the full burden and does meaningful work: 'local-only, never logged' is a concrete, verifiable privacy guarantee that matters greatly for a credential-handling tool, and it names the two outputs (entropy estimate, weakness flags). It stops short of stating whether the password is persisted in any form or how scoring is computed.

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?

One sentence does all the work: action first, output second, safety caveat last. There is no filler and nothing important is buried.

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 single-parameter, non-destructive utility with no output schema, the description is nearly sufficient – it discloses both the return concept and the privacy posture. Minor remaining gap is that the exact response shape (score scale, list of weakness categories) is unspecified.

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 0%, so the single 'password' parameter is undocumented in the schema. The description compensates only implicitly – it says the password's entropy is estimated, which tells the agent what to supply, but adds no guidance on length, encoding, or whether raw or masked input is expected.

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 pairs specific verbs ('estimate entropy', 'flag common weaknesses') with a clear resource ('a password'), so the agent knows precisely what it returns. It is also implicitly distinguished from hash-oriented siblings like compute_hashes and identify_hash, though it never names them.

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 purpose implies when to call it – before accepting or setting a password – but the description gives no explicit when-to-use, when-not-to-use, or alternative (e.g., compute_hashes for hashing rather than strength scoring). Usage must be inferred from the tool name and stated purpose.

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