vnt_proxy_capabilities

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

No annotations are present, so the description must disclose side effects and behavior. It only supplies an implementation hint ('implemented_via_native_sidecar') and ambiguous terms like 'DLL deploy' that could imply deployment, but does not clarify whether the tool reads, installs, or modifies anything. No return behavior or side effect is disclosed.

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?

The text is very short, but brevity is achieved by omitting necessary functional information rather than by efficient explanation. It is a fragment without a clear sentence structure, and 'implemented_via_native_sidecar' is redundant within the fragment.

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?

Given the cryptic description, empty schema, and no output schema, the agent lacks essential information about what this tool returns and how to use it. The existence of many capability/utility siblings makes the missing context particularly harmful.

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 tool has zero parameters and the schema is empty, so the baseline for parameter semantics is high. The description adds no parameter syntax or semantics, but none are needed.

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 provides no action verb; it reads as a subsystem label ('VNTextProxy: SjisTunnel / SRT·ASS + native sidecar DLL deploy') rather than explaining what invoking `vnt_proxy_capabilities` does. It restates the tool name's domain without distinguishing whether this lists, queries, or configures capabilities. Sibling tools like `vnt_proxy_sjis_encode` are not differentiated.

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 mention of when to use this tool or when to prefer alternatives. It neither lists context, exclusions, nor sibling relationships. The sibling list includes many proxy-related tools, but no guidance is given.

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