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

No annotations are provided, so the description bears the full burden of behavioral disclosure. It hints at a paid response but does not describe side effects, external charges, data handling, or return behavior. The description is too vague to inform the agent about any consequential behavior.

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?

The description is one short sentence, but its brevity is due to under-specification rather than efficiency. It spends its only sentence on price and account details instead of tool purpose, so the conciseness does not add value.

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 parameters, no annotations, and no output schema, the description must explain the tool's purpose and behavior. 'Every case in one response' is not enough to understand what 'archive' does, what input it accepts, or what output the agent should expect.

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 has zero parameters, so the baseline is 4 under the rubric. There is no parameter meaning to add beyond the empty schema, and the description's lack of parameter information is not a significant gap.

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 'Every case in one response. One payment, no subscription, no account.' does not state a verb or resource for the tool. It is a pricing/marketing statement that fails to indicate what 'archive' actually does or how it differs from siblings like 'research' or 'contents'.

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 guidance on when to use this tool versus the sibling tools. The mention of payment implies a purchase, but no conditions, alternatives, or exclusions are given, leaving the agent with no basis for selection.

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