soma_claim

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

With no annotations, the description carries the full burden. It does disclose two genuinely useful behavioral traits: the claim is exclusive ('эксклюзивно'), implying a lock/removal from the queue, and payment may be required for priced work. However it says nothing about permissions, failure modes, whether a claim can be released, or what happens on a duplicate claim.

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 compact sentences with the core action front-loaded and no filler. It is efficient, though the phrase 'получить контекст под бюджет' is cryptic enough that brevity shades into under-specification.

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 described, but for a mutating, exclusive-claim tool with zero annotations and 0% parameter coverage the description is too thin. It omits the semantics of id/agent, error conditions, and the release/lock lifecycle an agent would need.

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%, so the description must compensate, and it only partially does: 'квитанция' maps loosely to the optional payment parameter and gives the condition under which it is needed. The required id and agent parameters are never explained, leaving half the contract undocumented.

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 — 'Забрать конверт из очереди' (claim an envelope from the queue) — plus the exclusivity and context-retrieval outcome, so an agent can tell it apart from list-oriented siblings like soma_inbox. It does not explicitly name any sibling to sharpen the boundary, keeping it just short of a 5.

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 guidance on when to call this versus alternatives such as soma_inbox (peek) or soma_route. The only conditional ('if the work has a price, a receipt is required') is a parameter-level note about payment, not when/when-not usage guidance.

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