Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose behavioral traits such as whether the operation is read-only, destructive, or requires specific permissions. The description is minimal and does not add behavioral context beyond the tool name.
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 very concise at one sentence, with no unnecessary words. However, it could be better structured by front-loading key information. It is adequately sized but lacks depth.
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?
Given the complex nested input schema, multiple format options, and no output schema, the description is insufficient. It does not explain the return value, error cases, or how different formats affect output. The tool requires richer context to be fully usable.
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?
The input schema has descriptions for sub-parameters (left, right, formats) but the main 'state' parameter lacks a description. The tool description does not add any parameter information, leaving the agent to rely solely on the schema. Schema coverage is 0% for the top-level parameter, but sub-parameters are documented.
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 it compares text or data and returns a diff. The verb and resource are specific, and the tool's name matches the purpose. However, it lacks details on what types of diff outputs are available, which could be more precise.
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?
No guidance is provided on when to use this tool versus alternatives, or when not to use it. The description simply states what it does without context for decision making.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

v1.0.0diffScored across 1 tool
With only a single tool, there is no possibility of confusion or overlap between tools. The tool's purpose is clearly stated and distinct by default.
The single tool name 'diff' is concise, descriptive, and matches the server's purpose. There is no mixed convention or inconsistency since there is only one tool.
One tool is on the low end of typical server sizes, but for a narrowly scoped diff utility it is a reasonable and focused set. It doesn't feel trivial since diff is a meaningful operation.
The server's stated purpose is to compare text or data and produce a readable diff, which is exactly what the tool provides. There are no obvious gaps for this single-operation domain.
