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

No annotations are provided, so the description carries the full behavioral burden. It implies a read but never states that it has no side effects, nor does it cover behavior for an unknown watch_id or any permission requirements.

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?

One compact sentence that front-loads the resource before the field list, with no wasted words. Every listed field earns its place given there is no output schema.

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?

Enumerating return fields compensates for the missing output schema on a simple one-param read. However, with no annotations and no param documentation, error behavior and the meaning of watch_id remain unstated.

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?

Schema description coverage is 0%, and the description adds nothing about watch_id — it doesn't say whether it's the watch's name, UUID, or a returned id. The single parameter is near self-evident from its name, but the description does not compensate for the coverage 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 resource (one of your watches) and enumerates the returned fields, so the agent knows this is a read of watch state. It does not explicitly distinguish itself from siblings like watch_register or watch_cancel, but the 'current state' framing implies a read.

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?

There is no guidance on when to use this versus watch_register, watch_cancel, or deadman_checkin, and no prerequisites or exclusions are mentioned. Usage is only implied by the field list.

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