Execute any KIT API operation

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

With no annotations, the description carries the full burden and does so richly: warns calls hit the live store, writes take effect immediately with no sandbox, body is validated against the OpenAPI schema, and gives explicit guidance for 429/LIMIT_EXCEEDED/timeout (read back before replaying). This is unusually complete behavioral disclosure.

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?

Front-loads the escape-hatch purpose, then the live-store warning, then the workflow, then the replay caution. Every sentence adds distinct, decision-relevant information; no filler.

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?

For a complex 178-operation catch-all with no annotations and no output schema, it covers purpose, safety, workflow, validation, and error handling. It stops short of describing the response shape or error payloads, which is the main remaining gap.

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 schema already documents operation_id, body, query, path_params, and validate. The description adds only marginal meaning — the validation workflow and the get_operation_schema pointer — which is largely echoed in the schema itself, so baseline 3 applies.

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 and resource: executes any of 178 Yandex KIT API operations by operationId. Explicitly distinguishes itself from siblings as the fallback for operations without a dedicated tool, so an agent can route correctly without opening a 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 an explicit workflow (search_operations -> get_operation_schema -> kit_request) and states the exact condition selecting this tool: operations lacking a dedicated tool. Also states the validate=false escape option.

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