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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is fully covered. The description adds only that the output mirrors the public pricing page (static, unpaginated, non-personalized), a modest amount of context beyond the structured fields.

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?

Purpose is front-loaded in the first clause, and the remaining clauses are a compact routing block. The parenthetical URL reference and the multi-tool tail make it slightly dense, but no sentence is filler.

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?

With no output schema, the description carries the burden of describing returns, and it does so at a high level (offerings plus published prices, identical to the pricing page). For a zero-parameter informational read tool this is adequate, though it says nothing about output format or how many services are returned.

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, so the schema baseline is 4. The description correctly implies a no-input, whole-catalog read rather than hinting at filtering options that do not exist.

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 gives a specific verb and resource ('List Continuum service offerings and published prices') and anchors the content to a known artifact ('the same list as uxcontinuum.com/pricing'). An agent can immediately distinguish it from cost-estimate and booking siblings.

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?

It names the follow-on tools and their purposes (get_availability/book_call to book a free call, send_message for a note, request_estimate for a ballpark), which effectively routes the agent. It stops short of an explicit 'use this when you need pricing, not X' exclusion, so 4 rather than 5.

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