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

With no annotations provided, the description must disclose behavioral traits. It states that the tool stops monitoring and deletes the watch, which conveys the primary destructive action. However, it does not mention any side effects, irreversibility, permission requirements, or behavior when the watch does not exist. The description is minimally informative but not contradictory.

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 that is front-loaded with the primary verb. There is no redundant information, and it is appropriately sized for the tool's simplicity.

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 annotations, output schema, and parameter explanations, the description is incomplete. It lacks details on the token's purpose, expected input formats, and any success or failure behaviors. The tool is simple, but the description still leaves the agent without enough information to confidently invoke it correctly.

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 does not explain the meaning or purpose of the parameters (watch_id and token). It only names the fields without adding context, forcing the agent to infer that watch_id identifies the watch and token is likely an authentication credential. This is insufficient for a tool with no schema descriptions.

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 a specific verb (delete) and resource (watch), and the action of stopping monitoring. It distinguishes from siblings like check_watch, create_watch, and list_watches by indicating a destructive action. This is unambiguous.

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 its siblings (check_watch, create_watch, list_watches). It does not mention any conditions, prerequisites, or alternative scenarios. The agent is left to infer that deletion is appropriate when a watch is no longer needed, but this is not explicitly stated.

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