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

With no annotations, the description carries the full behavioral burden, and it does disclose two meaningful traits: the operation runs synchronously and it creates new translated articles (a write side effect). It stops short of stating permissions, idempotency, overwrite behavior for existing translations, or what the response contains.

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; the parenthetical efficiently carries the two key behavioral facts. Nothing is wasted, though it is arguably too terse for a mutation tool.

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 write tool with no annotations, no output schema, and 4 parameters at 25% schema coverage, the description should resolve the target_language vs target_languages ambiguity and say more about the resulting artifacts. It covers the mutation/synchronous facts but leaves key calling decisions to inference.

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 coverage is only 25% — only target_language is documented in the schema. The description's phrase 'one or more target languages' hints at the single-vs-multiple split between target_language and target_languages, but it never explains when to use which, and site_id/article_id carry no added meaning.

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 (translate an article) and a clear scope (one or more target languages). It implicitly separates itself from Edit_Article/Write_Article by producing translated copies, but it never names or contrasts a sibling explicitly.

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 when-to-use guidance, no prerequisites (e.g. whether the source article must exist, whether existing translations are replaced), and no mention of alternatives such as Edit_Article. The agent must infer all usage conditions 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.
