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

With no annotations, the description carries the full burden, but it only notes the output is a file path. It says nothing about permissions, whether the file is persisted to disk (a side effect), capture latency, or whether a camera must be online/selected.

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?

Two short sentences with the purpose front-loaded and no wasted words. Size is appropriate for a simple single-parameter tool.

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?

An output schema exists, so explaining the return value is not required, but the description omits any handling of the one input parameter and offers no usage context against the many sibling tools. Adequate for a trivial tool but with clear gaps.

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?

There is one parameter ('name') with a default of 'eufy_cam1' and 0% schema description coverage, yet the description never mentions how to target a camera or what values 'name' accepts. The description does not compensate for the schema gap.

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?

States a specific verb ('Capture') and resource ('a single JPEG frame from a camera'), which is clear on its own. However, it does not differentiate itself from the sibling 'clip_frame', which sounds like a closely related capture operation, so an agent has to guess which one applies.

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 on when to use this tool versus 'clip_frame', 'motion_clips', or 'recordings_info'. The agent is given no conditions or exclusions to route between the several capture/clip siblings.

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