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, but it reveals nothing about side effects, input expectations, network behavior, output format, or failure modes. 'Service Detect' implies some kind of detection operation but gives no behavioral detail.

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 description is trivially short, but this is under-specification, not conciseness. It is a single redundant sentence with no structure, no front-loaded key information, and no useful content.

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?

Three optional parameters, no annotations, no output schema, and a huge sibling list. The description provides no information about what 'service detect' does, what inputs are expected, what it returns, or what distinguishes it from similar tools. It is completely inadequate.

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 description coverage is 100%, so each parameter (host, port, input) has a minimal description, but all three are described as 'X to process' with no additional semantics. The baseline for full coverage is 3; the description adds no extra meaning beyond the schema.

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 is 'Service Detect: Service Detect', which is a pure tautology that merely restates the tool name with no verb, resource, or scope information. It does not say what the tool does, what it detects, or how it differs from siblings like service_discovery or service-audit.

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?

No guidance is provided about when to use this tool versus alternatives such as service_discovery, service-audit, or banner-grab. The description gives no context, no exclusions, and no examples, leaving the agent with no basis for selection.

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