Renforge Estimate Translation

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not say whether the operation is read-only, what 'stable' means, what the output looks like (beyond implying a translation result), or any constraints on input frames.

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 single sentence is front-loaded and contains no filler. However, given the tool's complexity, it may be too terse to be optimally structured for an agent needing to understand configuration options.

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 tool with 8 parameters, an output schema, and no annotations or schema descriptions, the description is significantly incomplete. It omits usage context, parameter explanations, and behavioral traits, leaving the agent with little beyond the name and required inputs.

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?

All 8 parameters lack schema descriptions (0% coverage). The description references 'two saved frames' which loosely maps to the required before_path and after_path, but it provides no meaning for the six optional parameters (region_x, region_y, max_shift, threshold, region_width, region_height).

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 clear verb ('Estimate') and resource ('visual translation between two saved frames'), making the core action understandable. It does not differentiate from sibling tools like diff_screenshots or mention any scope boundaries, so it stops short of a 5.

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, when not to, or which alternatives exist. The description only states what it does, leaving the agent to infer appropriate usage from the name and siblings.

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