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

readOnlyHint=true already covers the safety profile, so the bar is lower, yet the description adds genuinely useful scope context: an explicit negative enumeration of data domains it will never return (account, tenant, clinical, patient, registration, billing, chatbot). This prevents misuse for lookups it cannot satisfy. It does not mention caching, freshness, or rate limits.

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?

Two sentences, no filler: the positive capability (overview + canonical source URLs) is front-loaded, and the exclusion list follows. Every clause carries information the agent needs.

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-value shape need not be explained. For a read-only, zero-parameter overview tool, the description covers capability, scope boundaries, and exclusions; the only missing element is explicit routing guidance relative to the four sibling tools.

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 tool takes zero parameters, and the schema is a closed empty object with 100% description coverage, so there is nothing for the description to disambiguate. Baseline 4 for a no-parameter tool is appropriate.

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 verb and resource (returns a CloudMedico public-product overview plus canonical public source URLs), which is clear enough to distinguish this broad overview tool from the narrower siblings get_faq, get_features, and get_pricing. It does not explicitly name any sibling, so it falls short of full routing clarity.

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?

Usage is implied rather than stated: the phrase 'public-product overview' and the list of excluded data domains signal this is for general public product information, not account or clinical lookups. However, it never says when to prefer this over get_features, get_pricing, get_faq, or search_public_knowledge, so an agent must infer the routing.

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