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

The annotations only declare readOnlyHint=true, so the description usefully adds scope beyond that: it discloses that pricing is subject to the published page and market qualifiers, and enumerates what data the tool does not access (account, tenant, clinical, patient, billing, etc.). These data-boundary disclosures are valuable context that the annotations do not carry.

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 with the core action front-loaded, followed by scope caveats. No wasted phrasing, though the enumerated list of excluded data types is somewhat long for a simple pricing lookup.

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 formatting need not be explained. For a zero-required-parameter read-only lookup, the description covers the resource, the caveat about pricing volatility, and the data-access boundaries, which is sufficient for correct invocation.

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 100%, so the single optional 'market' parameter is already documented in the schema as 'Optional market or country context for the published pricing information.' The description's mention of 'market-specific qualifiers' loosely reinforces this but adds no syntax or format detail. Baseline 3 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 the canonical public CloudMedico pricing page.' This clearly distinguishes it from sibling tools like get_features, get_faq, and get_product_overview by resource, though it does not explicitly name those alternatives.

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 explicit when-to-use guidance or named alternative. An agent might reasonably wonder whether pricing questions should route here or to search_public_knowledge, and the description does not resolve that. Usage is only implied by the resource name.

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