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 covered. The description still adds genuine value beyond them by clarifying 'It does not take payment' — important because the tool surfaces checkout links and an agent could otherwise assume it initiates a transaction. It stops short of describing freshness of pricing or any 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?

Three sentences, front-loaded with the core purpose, then routing, then the payment clarification. The enumeration of covered products is dense but each item carries selection value; nothing is redundant 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 input parameters and no output schema, the description carries the burden of explaining what comes back, and it does so by naming the price categories, seat tiers, co-branding and Rollout Pack plus the checkout links. An agent knows both what it gets and what it must not expect (no payment action).

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 there is no parameter semantics to explain; this is the baseline case. The description correctly avoids inventing inputs and instead spends its words on what is returned.

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?

States a specific verb+resource ('Returns current one-time prices and checkout links') and enumerates exactly what is covered: Framework + Executive Suite, Framework alone, AI at Work seats, seat tiers, co-branding, and the Rollout Pack. It also explicitly distinguishes itself from get_seat_quote and assess_ai_readiness, so an agent can separate it from siblings without opening a schema.

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?

Gives explicit routing: 'Use it for the full price list, or get_seat_quote for a specific number of seats,' and adds a second alternative for a different intent ('To check readiness, use assess_ai_readiness'). When-to-use and when-to-use-something-else are both stated, not implied.

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