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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered. The description adds real context beyond that: it names exactly what gets destroyed (remote view content/state) and what survives (pairing and account authorization), which is the key question an agent has before calling a destructive tool.

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 sentences, both front-loaded with the essential information and no padding. The destructive action comes first and the scope caveat second, which is the right ordering for an agent scanning the definition.

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 not be spelled out, and the destructive scope is well covered. However, for a two-parameter mutation tool with zero schema description coverage, leaving both parameters unexplained and never noting auth or permission requirements leaves 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?

Schema description coverage is 0% across two parameters, and the description says nothing about either. The meaning of 'device' is inferable, but 'client_request_id' is a patterned request-tracking field that is particularly worth explaining given the annotation says the operation is not idempotent.

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 states a specific verb and resource: it 'deletes remote view content/state' and returns the device 'to its Start page.' That is concrete enough to distinguish a view-state reset from sibling operations like page_delete or display_show_default, though it never names an alternative explicitly.

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 sentence 'This is not a factory reset; pairing and account authorization stay' clarifies scope boundaries, which is useful, but it addresses what the tool is not rather than when to choose it over siblings such as display_show_default or page_delete. Usage must be inferred.

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