renforge_estimate_translation

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

No annotations are provided, and the description is a single sentence with no details about side effects, return behavior, permissions, or operational constraints. It does not disclose any behavioral traits beyond the basic operation.

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?

The description is a single concise sentence with no wasted words. However, it is under-specified for the tool's complexity, which slightly reduces the score.

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?

The tool has 8 parameters, no parameter documentation, and no behavioral details. The presence of an output schema does not compensate for the complete lack of input and usage context.

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?

With 8 parameters and 0% schema description coverage, the description adds no meaning to parameter names. It only implies 'saved frames' (before_path and after_path) but leaves region_x, max_shift, threshold, etc., unexplained.

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 clearly states the tool's function with a specific verb 'estimate' and resource 'stable visual translation between two saved frames.' It is distinct but does not explicitly differentiate from sibling tools like renforge_diff_screenshots, so it earns a 4.

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 this tool versus alternatives, no exclusions, and no mention of prerequisites. The description provides no context for tool selection.

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