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

No annotations are present, so the description carries full behavioral burden. It implies a state-changing completion ('close') and that a result is supplied, but omits permissions, side effects, reversibility, or any rate limits.

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?

A single short sentence with no filler, but it is under-specified for a tool with three parameters and no schema descriptions. It is front-loaded yet too terse to earn its place as sufficient guidance.

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 a three-parameter mutation tool with no annotations and 0% schema coverage, the description is far too sparse. Although an output schema exists, the description still fails to cover parameter semantics, usage context, or behavioral traits.

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% for all three parameters (id, agent, result). The description only echoes 'result' without explaining its format or the roles of id and agent, adding no meaning beyond the schema.

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 ('Закрыть' / close) and resource ('конверт' / envelope) plus the instrument ('результатом работы' / with the work result). It does not differentiate from siblings like soma_send or soma_route, but the action is clear enough for an agent in this ecosystem.

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?

Provides no when-to-use guidance, no prerequisites, and does not mention any alternative tools such as soma_send or soma_route. The agent must infer usage entirely.

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