The plans for sale, with price and term, and the account's active plan. Each purchase lasts 30 days, with no automatic renewal. Each purchase lasts 30 days, with no automatic renewal. Without an account or wallet credential, account is null.

B3.4/5.0
Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds genuine context beyond them: purchases are 30-day terms with no auto-renewal, and `account` is null without an account or wallet credential — a useful auth-related behavior note.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two of the three sentences are useful and front-loaded, but 'Each purchase lasts 30 days, with no automatic renewal.' appears verbatim twice. That duplication is pure waste and suggests an unedited definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no parameters, the description carries the full burden of explaining what comes back. It names price, term, and the active plan field, but says nothing about the shape of the returned list (identifiers, currency, plan metadata) an agent would need to act on the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there is nothing to disambiguate and the baseline of 4 applies. The description correctly devotes no space to parameter documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States the resource precisely: the plans for sale with price and term, plus the caller's active plan. That is enough for an agent to distinguish it from buy_plan/cancel_plan, though no sibling is named explicitly and the tool's verb is only implied by the name.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no 'use this when' instruction and no mention of alternatives such as pricing, get_bundle, or buy_plan. The only conditional statement is about credentials producing a null `account`, which is about output, not about when to select this tool.

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