iptime_status

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds meaningful behavioral context beyond the annotations: the tool may detect the router interface and may perform authentication when configured. No contradiction with the annotations exists.

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 a single compact sentence that front-loads the primary action and packs multiple steps without waste. Every clause earns its place, and there is no redundant restatement of the tool name or annotation hints.

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?

The tool is simple (one optional parameter, rich annotations), but the absence of an output schema means the description should clarify what 'product/system status' includes and how authentication is triggered. The phrase 'authenticate if configured' is ambiguous about whether the agent should call iptime_login first. With many siblings, this ambiguity is a real gap, though the core invocation is otherwise covered.

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%: the single optional router_id parameter is fully described in the schema. The description adds no additional parameter-level meaning. This matches the baseline of 3 for high schema coverage.

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 clearly states a specific verb ('read') and resource ('product/system status'), plus distinct preprocessing steps ('detect the router interface, authenticate if configured'). It is not a tautology and gives an agent a usable idea of what the tool accomplishes. It does not explicitly differentiate from the sibling iptime_read, so it misses the top score.

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?

The description implies an operational sequence (detect, authenticate, read) but gives no explicit guidance on when to choose this tool over siblings like iptime_read or iptime_login. It does not mention prerequisites, alternatives, or exclusions. The agent is left to infer the intended use case.

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