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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description does add genuine context beyond them: that the lookup works offline and that local publishing is free, which implies no auth or network dependency. It still says nothing about whether results vary by org or what the price data covers.

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?

It is short and front-loaded, but the brevity comes from omission rather than efficiency: a fragment plus an unrelated parenthetical. Nothing is padded, yet the single sentence spends half its words on metadata rather than purpose.

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 should convey what is returned (plan names, tiers, currency, per-seat vs per-org pricing). Instead an agent learns only that 'prices' exist, leaving the response shape entirely unknown for a tool whose whole value is its data.

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% and the single optional 'org' parameter is fully documented as 'Org id (default: your first org)'. The description adds nothing about how org selection affects returned prices, so the baseline 3 applies.

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 is essentially the title restated ('Statuz Cloud prices'), with no verb or object such as 'retrieve the plan list and per-seat pricing'. It never distinguishes itself from close siblings like cloud_billing_balance or cloud_billing_ledger, so an agent cannot tell which of the billing/pricing tools answers a cost question.

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 indication of when to call this versus cloud_billing_balance, cloud_billing_ledger, or cloud_org_list. The parenthetical hints that lookup works without a network connection, but no exclusion or alternative is named.

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