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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), so the description 'Только чтение' is reinforcing. It adds real context beyond the annotations: newest-first ordering, the required tariff/permission, the exclusion of respondent answers, and a field-by-field breakdown of each entry (action/source/actor/target/meta).

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?

Purpose and ordering are front-loaded, and the enumeration of events, entry fields, and constraints all earn their place. It is dense and somewhat long, but no sentence is filler and nothing essential is buried.

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?

There is no output schema, so the description must carry the return contract, and it does by describing ordering and the action/source/actor/target/meta fields. Combined with a fully documented parameter schema and explicit read-only/tariff prerequisites, an agent has enough to call it correctly.

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 100%, so the baseline is 3. The description explains the shape of returned records but adds no meaning to the input parameters (from/to/group/page/quiz_id/user_id) beyond what the schema already documents.

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+resource ('Возвращает журнал действий аккаунта') and enumerates the exact event categories covered (quiz lifecycle, answers, members, roles, folder access, denials) plus the entry structure. An agent can distinguish it from get_workspace_members, get_integration_logs, or get_quiz_webhook_logs without opening the schema.

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?

Gives prerequisites (a tariff that includes the activity log and the 'View participant activity' permission) and an explicit boundary ('Ответов респондентов в журнале нет'), steering the agent to answer-level tools for that data. It stops short of naming which sibling to use for the excluded case, so it is clear context without full alternative routing.

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