enum4linux_scan

Enumerate SMB/NetBIOS services to discover users, shares, groups, password policy, OS info, and printers. Use optional credentials for authenticated enumeration.

Instructions

Full SMB/NetBIOS enumeration using enum4linux (-a covers all). Enumerates: users, shares, groups, password policy, OS info, printers. target: IP address of Windows/Samba host username: optional username for authenticated scan password: optional password for authenticated scan

Behavior3/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains that it runs enum4linux with -a and enumerates specific information, but does not disclose potential side effects (e.g., network traffic, time to complete, or that it may be considered intrusive). Since there are no annotations to rely on, the description adds some context but leaves out important behavioral traits.

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

Conciseness5/5

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

The description is very concise and well-structured: first sentence states the tool and the '-a' flag, second lists what is enumerated, then three lines map parameters to their meanings. No filler or redundancy exists; every line earns its place.

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

Completeness4/5

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

Given the tool's complexity (a broad enumeration tool) with no annotations and no output schema, the description covers the essential aspects: purpose, scope of enumeration, and parameter meanings. It does not mention return values or output format, but this is somewhat implied for a scan tool. It lacks notes on runtime or prerequisites, but is adequate for a straightforward enumeration tool.

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

Parameters4/5

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

Schema description coverage is 0%, so the description must compensate. It successfully describes all three parameters: target as IP address, username as optional for authenticated scan, and password as optional for authenticated scan. This adds meaningful semantics beyond the schema's bare property names and defaults, though it doesn't detail formats or edge cases.

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 states the specific verb 'enumeration' and resource 'SMB/NetBIOS' using enum4linux, and explicitly lists the categories enumerated (users, shares, groups, password policy, OS info, printers). This clearly distinguishes it from sibling tools like smbclient_list_shares, which only covers shares.

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

Usage Guidelines3/5

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

The description implies usage when comprehensive SMB/NetBIOS enumeration is needed ('Full... -a covers all'), and the enumeration list gives context. However, it does not explicitly state when not to use it or mention alternatives like smbclient_list_shares for share-only enumeration. No exclusions are provided.

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