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

With no annotations, the description carries the full burden. It adds the useful context that thresholds follow ICH Q3A/Q3B guidance, but says nothing about the api_key authentication requirement, what is computed or returned, or how batch_peaks are processed. For an unannotated tool this is a significant gap.

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 efficient and front-loaded, but it is under-specified rather than truly concise, packing regulatory jargon without actionable detail. Every word earns its place, yet too few words are present to guide invocation.

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 needn't be explained, but with three undocumented parameters, no annotations, and no usage context, the definition is inadequate for an agent to call this tool correctly. It supplies regulatory framing but not operational completeness.

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% across all three parameters. The description adds no meaning for api_smiles, batch_peaks, or api_key, so the agent cannot tell what form the SMILES should take, what peak data is expected, or how the key is used. It fails to compensate for the coverage gap.

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 specific resource (impurity profiling) and its regulatory framing (ICH Q3A/Q3B with thresholds), so an agent knows this tool evaluates impurities against regulatory limits. However, it does not differentiate itself from close siblings like covams_impurity_find or covams_mass_balance, leaving ambiguity about which impurity tool to pick.

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 when-to-use guidance, no prerequisites, and no named alternative. The agent must infer from the name alone when profiling is appropriate versus covams_impurity_find or covams_degradation_predict.

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