Check target scope

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description still adds genuine value beyond them: 'performs no network request' tells the agent this is purely local decision logic with no outbound traffic or side effects, which matters in a security-assessment context, and 'explain' signals a reasoned response rather than a bare boolean.

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 compact sentence with the primary function front-loaded and no filler. It is efficient, though the brevity is partly under-specification rather than disciplined concision.

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?

An output schema exists, so return values need not be described, and annotations cover the safety semantics. However, the accepted target format and the choice between this tool and batch_scope_check are left unaddressed, which are real gaps for a gating 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 0% and the description never mentions the single required 'target' parameter, so it does not clarify whether a target may be a hostname, URL, IP, or CIDR range. With low schema coverage, the description should compensate but adds nothing here.

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 pair ('validate and explain') and the resource ('target' authorization), so the agent knows exactly what the tool determines. It does not differentiate itself from the sibling batch_scope_check, leaving the single-vs-batch distinction to be inferred.

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?

There is no when-to-use guidance, no prerequisite statement, and no named alternative such as batch_scope_check for multiple targets. The pre-scan gating role is only weakly implied by the word 'authorized'.

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