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

No annotations are provided, so the description carries the full behavioral burden. It notes the target is the 'active draft' but says nothing about concurrency/revision conflict behavior, whether a new revision is created, what happens to text outside the range, or error conditions for an out-of-range start/length.

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 waste, but it is under-specified rather than genuinely concise — brevity here comes at the cost of missing usage and behavioral context.

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 6-parameter mutating tool with no annotations, an output schema, and optimistic-concurrency semantics, the one-line description is too thin. It should at minimum explain the revision_id conflict model and the result of the replacement, none of which is stated.

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 every parameter (start, length, replacement, revision_id, created_by) is already documented in the schema. The description adds no formatting, indexing, or unit details beyond what the schema states, 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 concrete verb ('Заменить') and resource ('диапазон содержимого активного черновика артефакта'), so the operation is identifiable. However it does not distinguish itself from close siblings such as replace_substring_in_artifact, overwrite_artifact, or replace_article_text, leaving the agent to guess which mutator applies.

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 use range replacement versus substring replacement or full overwrite, no prerequisites (e.g. requiring the current revision_id or an unfinalized draft), and no exclusions. The agent must infer all routing decisions from the name alone.

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