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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the mutation profile is covered. The description adds value beyond them: an authentication requirement ("needs account token"), a billing note ("Does not charge"), and the public-visibility consequence of removing the password.

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 short sentences, with the prerequisite front-loaded in parentheses and no redundant restatement of the name or title. Every clause carries distinct information.

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 mutation with annotations covering safety and no output schema, the description covers the essentials: auth need, effect, and cost. It could still note behavior when no password is set, but nothing critical for invoking it correctly is missing.

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% for the single required "site" parameter, which is fully documented with an example in the schema. The description adds nothing about parameter format or syntax, so the baseline 3 applies.

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?

States a specific verb and resource ("Removes the password from a claimed site") plus the resulting effect ("so anyone can open it"), which clearly distinguishes it from the sibling set_site_password. It does not explicitly name that sibling, but the operation is unambiguous.

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 parenthetical "(needs account token)" supplies a prerequisite, which is genuine usage context. However, it never states when to prefer this over set_site_password or any alternative, and gives no when-not conditions, leaving usage only implied.

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