websex_subzy

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

With no annotations, the description carries the full burden. It usefully discloses that the container executes subzy directly with argv tokens and never uses shell parsing (a meaningful safety/injection trait), and that it runs scoped to an engagement namespace. However, it says nothing about network access, expected runtime, or side effects of the underlying tool.

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?

Three compact sentences with no filler, and the execution model is front-loaded. The wording is efficient, though it spends space on shell-parsing mechanics rather than the tool's purpose.

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 explained. But with no annotations and 0% schema description coverage, the description should compensate more than it does: it omits what subzy does, its network behavior, and the stdin parameter, leaving an agent able to invoke it mechanically but not to judge when it is the right 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 coverage is 0%, so the description must explain the 4 parameters. It hints at the argv list ("supplied argv tokens"), the engagement scope ("engagement namespace"), and relative working paths, but the stdin parameter is never addressed and no parameter is named or typed. It compensates only partially.

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?

"Run subzy from the WebSex web toolkit" essentially restates the tool name without saying what subzy does (subdomain takeover detection) or what domain it targets. An agent unfamiliar with subzy cannot tell from this text what the tool accomplishes or how it differs from siblings like websex_subfinder or websex_amass.

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 guidance on when to use this tool versus the many sibling recon/subdomain tools. The only usage-adjacent instruction is "use relative paths for engagement artifacts," which is an operational constraint, not a selection rationale.

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