pentest_scope_check

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the check is non-intrusive and evaluated against a pre-loaded scope rather than a live target, which is real value beyond the schema. It does not disclose the outcome shape (boolean vs. detailed result), error behavior when scope is unloaded, or whether matching is exact/CIDR/subdomain based.

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 short sentence with no filler, and the scope-check purpose is front-loaded ahead of the non-intrusive qualifier. Nothing is redundant.

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?

This is a low-complexity, single-parameter tool with no output schema, so the bar is modest, but the description leaves two gaps an agent needs: the accepted format of 'target' and what a positive or negative result looks like. It is adequate to identify the tool's role but not to call it confidently.

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?

The single parameter has 0% schema description coverage, so the description must compensate and does not. 'Target' is ambiguous: it could be a hostname, IP, CIDR range, or full URL, and the matching semantics of that string are never explained, leaving the agent to guess at valid input.

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 specific verb and resource: checking whether a target falls inside the loaded engagement scope. It also adds a meaningful qualifier ('without touching it') that no sibling tool offers, so an agent can distinguish this pre-flight check from active scanners like pentest_recon_portscan. It stops short of naming sibling tools, but none are close enough to be confused with it.

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 phrase 'without touching it' implies this is a safe pre-flight gate before active testing, and 'the loaded engagement scope' implies an engagement must be loaded first. However, neither is stated as an explicit when-to-use rule, and there is no guidance on what to do when no engagement is loaded or when the check fails.

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