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

With no annotations, the description carries the full behavioral burden. It does disclose an important boundary — that this does not write to translation memory, which is the main wrong-action risk — but it omits whether feedback overwrites prior feedback, whether it requires an existing translation/review object, and permission requirements. Useful but incomplete for a mutation tool with zero annotation coverage.

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?

Two short sentences, with the core action front-loaded and the disambiguation second. The trailing line break/indentation is slightly awkward but nothing is redundant. Every sentence carries information.

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, so return values needn't be explained, but the tool has five undocumented all-optional parameters and no annotations, and the description addresses none of that. For a feedback-recording mutation where an agent must decide which fields to populate, the definition leaves the critical invocation detail unaddressed.

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 0% across five optional parameters (result, source, approved, feedback, language), and the description adds no meaning beyond the parameter names. It never explains what 'source' vs 'result' represent, whether approved and feedback are mutually exclusive, or what happens when all params are null. The names are partly self-evident, which keeps this above 1.

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 specific verb and resource ('Save user feedback or an approval rating for a translation') and explicitly distinguishes itself from the sibling add_translation_memory_entry. It stops short of 5 because it doesn't fully position itself against the broader review/translation siblings (e.g. get_subtitle_review, update_subtitle_review) that an agent might confuse it with.

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?

It gives clear usage context: use this to record feedback/approval, and use add_translation_memory_entry instead when the goal is persisting an approved translation for future reuse. That is an explicit alternative with a selecting condition. No when-not-to-use or prerequisite conditions (e.g. required identifiers) are stated.

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