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

Annotations already declare it is a non-readonly, non-idempotent, non-destructive mutation. The description adds the useful partial-update contract ('пропущенные настройки сохраняет'), clarifying that omitted settings are preserved — genuinely beyond the annotations. It still omits auth requirements and the effect on unspecified settings during the merge.

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 tight sentences with zero waste, and the scope (what it changes) is front-loaded ahead of the partial-update behavior.

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?

No output schema exists, so return values need not be described. However, for a mutation with 8 params at 0% schema coverage, the description leaves three settings unexplained and gives no usage context, so it is only partially sufficient.

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 coverage is 0% across 8 params, so the description must compensate, and it names five of them (язык=locale, тема=mode, акцент=accent, плотность=density, анимации=motion). It leaves custom_hue, glass_intensity, and sidebar_collapsed entirely undocumented and gives no format/syntax detail beyond the schema enums.

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 (меняет/changes) plus the resource (panel appearance) and enumerates which settings are affected (language, theme, accent, density, animations), so an agent knows what the tool does. It does not, however, differentiate itself from the sibling account_update, which plausibly overlaps.

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 when-to-use guidance, no mention of prerequisites, and no routing away from or toward alternatives such as account_update or account_security. The agent must infer that this touches only visual settings.

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