get_witzense_live_url

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only states that it retrieves a URL but does not mention any side effects, required permissions, or limitations. Since it is a 'get' operation, it likely is read-only, but that is not explicitly stated, and no further behavioral traits are 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 description is concise with no unnecessary words, but it lacks any structural organization beyond a single sentence. It is front-loaded but under-specified. While brevity is a positive, the extreme terseness reduces its utility, making it hard to extract any actionable details.

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 tool has three parameters (including an enum for type and voice) and no output schema or annotations, the description is incomplete. It does not explain what 'live or historical' means in the parameters, what values are expected, or what the returned URL format is. The sibling tools suggest a broader context, but this description fails to provide sufficient context for correct usage.

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 schema description coverage is 0%, and the description provides no information about the parameters (imei, type, voice). It does not explain what these parameters represent or how they affect the output. The description is entirely inadequate for guiding parameter usage, as it does not compensate for the lack of schema descriptions.

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 the tool fetches a streaming page URL for a device, with a distinction between live and historical. It uses a specific verb and resource, making the primary function understandable. However, it does not differentiate from sibling tools like get_witzense_rtmp_url, which also deals with streaming URLs, so it lacks explicit differentiation.

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 on when to use this tool versus alternatives. The description is a single sentence with no context about typical use cases, prerequisites, or distinctions from similar sibling tools. It does not mention exclusions or when not to use it.

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