cmw_wlan_fetch_frequency_error

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. It only says 'Fetch... results', which implies a read operation but does not describe the return format, whether a measurement must be triggered beforehand, or any side effects. This is very minimal.

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 sentence that is concise and front-loaded with the core action. It does not waste words, but it is under-specifying relative to the tool's complexity. Still, for brevity alone, it earns a solid score.

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 no annotations, no output schema, and low schema parameter coverage, the description needed to provide much more context. It does not mention measurement triggering, what a 'frequency error' result entails, or how the parameters relate to the operation. This is inadequate for a tool in a measurement suite with many sibling tools.

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 description adds no information about the parameters (host, port, meas_instance). Schema description coverage is only 33% (only meas_instance has a description), so the description needed to compensate for host and port but did not. The tool description is silent on all three parameters.

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 action ('Fetch') and the resource ('WLAN frequency error measurement results'), making the tool's purpose immediately understandable. While it does not explicitly distinguish itself from sibling tools like cmw_wlan_fetch_evm or cmw_wlan_fetch_power, the resource name is specific enough to avoid major ambiguity.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention any prerequisites such as triggering a measurement first or configuring a WLAN connection. This is a significant gap for a tool that likely depends on a measurement setup sequence.

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