Behavior2/5

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

The description mentions evasion techniques but does not disclose behavioral traits such as speed impact, potential blocking, or dependency on sudo. No annotations are provided to compensate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, which is concise but overly brief given the 8 parameters. It lacks structure and context, though it is not verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 8 parameters, no schema descriptions, and no annotations, the description is insufficient. It does not explain parameter behavior, output format, or prerequisites, leaving significant gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description must explain parameters. It only hints at techniques (fragment, decoy, proxy, MAC) but does not describe 'source_port', 'timeout', 'sudo', or the 'technique' enum values. Parameter semantics are largely missing.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool is for firewall/IDS evasion scanning and lists specific techniques (fragmentation, decoys, proxies, MAC spoofing). This distinguishes it from other nmap scan tools like nmap_quick_scan or nmap_scan.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use it, or which sibling tools to use instead.

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