slope_calc

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

The description does disclose a payment requirement ($0.001 USDC via x402), which is a useful behavioral fact. However, with no annotations, the description carries the full burden and does not disclose whether the tool is read-only, what inputs it expects, or what it returns.

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 extremely short, but its brevity comes at the cost of essential information. The first sentence is redundant with the tool name, and the second only states the cost; the description is under-specified rather than efficiently concise.

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 computational tool with no annotations, no output schema, and a generic parameter object, the description is insufficient. It does not explain how to invoke the tool, what inputs to pass, or what result to expect, leaving the agent unable to use it correctly.

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 only a generic 'params' object with a boilerplate description ('Tool parameters as JSON object'), and the tool description adds no detail about required slope parameters. An agent cannot infer what fields to provide (e.g., x1, y1, x2, y2).

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 only repeats the tool name 'slope calc' and labels it as 'Other Utilities tool,' without stating the actual operation (e.g., 'calculates the slope of a line between two points'). It fails to distinguish the tool from sibling calculation tools like distance_calc or geometry_calc.

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 usage guidance is provided. The phrase 'Other Utilities tool' is a broad category, not a use case, and there is no mention of when to prefer this tool over alternatives or any prerequisites.

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