dahua_nvr_get_channels

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

With no annotations, the description alone carries the burden of behavioral disclosure. It merely states what the tool does without revealing any behavioral traits such as return format, error handling, or performance characteristics. This is entirely insufficient.

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 concise sentence with no redundant words, front-loading the purpose immediately. It is well-structured and efficient.

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 absence of an output schema and annotations, the description should compensate by specifying what is returned (e.g., list of channel IDs) and any relevant behavior. It does not, leaving the agent with only a vague notion of 'camera channels'.

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 already fully describes the single parameter (device_id) with a clear description, so the description adds no additional semantic value. Per the baseline rule for high schema coverage, this scores a 3.

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 uses a specific verb ('Get') and resource ('camera channels connected to a Dahua NVR/DVR'), clearly distinguishing it from sibling tools like dahua_nvr_system_info or dahua_nvr_channel_status. It precisely states the tool's function.

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 exclusions or prerequisites. The only implied usage is the purpose itself, but there is no explicit context or comparison.

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