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

No annotations are provided, so the description carries the full behavioral burden, and it says almost nothing: no indication of required input (a fitted RSM model), no permission/auth notes beyond an api_key param, no statement of what the output contains. It only lists three result artifacts without explaining their meaning or the tool's assumptions.

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?

It is a single tight sentence with the key outputs front-loaded and no filler, which is good structure. But the brevity reflects under-specification rather than economy, so it cannot score high.

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 need not be described. Still, for a nested-object input with no annotations and no schema documentation, the description omits what the tool requires and when it applies, leaving an agent unable to invoke it correctly with confidence.

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%; the required 'model' object has no description and api_key is undocumented beyond a default. The description never mentions either parameter, so it does not compensate for the coverage gap — an agent gets no guidance on the shape or provenance of the required model.

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 names a specific analysis (canonical analysis) and enumerates its outputs (eigenvalues, stationary point, surface nature), which lets an agent infer it characterizes a fitted response-surface model. However it uses a noun-phrase listing rather than a verb+resource statement and does not distinguish it from close siblings like covadoe_ridge_analysis or covadoe_fit_rsm, whose outputs overlap.

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 when-to-use, prerequisites, or alternatives are given. An agent cannot tell from the text whether a fitted model must exist first or when to prefer this over covadoe_ridge_analysis (which handles ridge/stationary-ridge cases). Usage must be inferred entirely from the tool name.

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