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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description adds the prerequisite that a stable watch_id from Remode is required and gates invocation on user intent, but says nothing about what stopping actually destroys (watch history, alerts, reversibility).

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?

Three short sentences, front-loaded with the action and followed by the precondition and the required input. No filler, though the repeated 'Remode' reference is slightly redundant.

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 return values need no explanation, and annotations cover the destructive/idempotent profile. The description supplies the user-intent precondition and input provenance, leaving only minor gaps such as side effects of stopping a hunt.

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 one parameter with 0% description coverage, so the description must compensate. It does partially by identifying the parameter's provenance ('the stable watch_id returned by Remode'), but adds no format, length, or validity detail beyond what the schema's type and length constraints imply.

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 and resource ('Stop an existing Remode Hunt') and clarifies the object of the action as 'tracking an item', which distinguishes it from siblings like watch_item and update_watch. It does not name those siblings explicitly, so differentiation is inferred rather than stated.

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?

'Use only after the user asks to stop tracking an item' gives an explicit precondition and confirmation gate. It stops short of naming the alternative tool for other watch-management needs, so it is clear context without exclusions.

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