dahua_nvr_recording_status

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

No annotations are provided, so the description must carry the full burden of disclosing behavior. It only says 'Get', which implies read-only, but it does not explain what the recording status/mode values are, whether it queries the entire NVR or a channel, or any potential side effects or return format.

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 one concise sentence with no filler. It communicates the essential purpose efficiently.

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 has no output schema, so the description should explain what the return value looks like. It does not, leaving the term 'recording status/mode' ambiguous. Given the simplicity of the endpoint, a bit more detail about possible values or the targeted scope would make it complete.

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 has 100% coverage for device_id ('Dahua NVR device ID'), so the baseline is 3. The description does not add additional parameter semantics beyond the schema, but the single parameter is straightforward and self-explanatory.

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's function: 'Get recording status/mode from a Dahua NVR'. It uses a specific verb and resource, and the scope distinguishes it from sibling tools like dahua_nvr_system_info, dahua_nvr_get_channels, and dahua_nvr_storage_info.

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, and no exclusions or prerequisites are mentioned. The only implied context is from the tool's name and purpose, but there is no explicit comparison to similar tools like dss_record_status or dahua_nvr_channel_status.

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