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

No annotations are provided, so the description carries the full disclosure burden for a mutation tool. It never states whether the operation is idempotent, whether clearing the flag deletes stored data or affects storage quota, whether the target version must be final, or what permissions are required.

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 front-loaded sentence with no filler or repetition. It is efficient; the shortfall is missing content rather than excess, but the phrasing itself is tight.

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 and all parameters are required and well-described, so the basics are covered. For an un-annotated mutation tool, however, the description should say what setting or clearing the flag actually does to the artifact, which it omits.

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 all three parameters are already documented in the schema and a baseline of 3 applies. The description adds only marginal meaning, reinforcing that 'version' refers to the final version, without clarifying edge cases for artifact_id or is_persistent semantics.

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 uses a concrete verb phrase ('Установить или снять флаг') tied to a specific resource concept ('постоянного хранения финальной версии артефакта'), so the operation is unambiguous. It does not, however, distinguish itself from nearby siblings like finalize_artifact or overwrite_artifact, whose names also touch artifact versions.

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 explicit when-to-use or when-not-to-use guidance, and no mention of the alternative of, say, finalizing or reverting an artifact. The only hint is the phrase 'финальной версии', which weakly implies the version must already be finalized.

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