AgentReady (Base wallet readiness)

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

With no annotations, the description carries the full burden and does disclose useful traits: it is free, operates on Base, and checks both format and contract-vs-EOA status. However, it does not say what happens for invalid input, whether the call is strictly read-only with no side effects, or what the result looks like.

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 a single front-loaded sentence with zero wasted wording. 'Free' comes first and every clause adds relevant information.

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?

For a simple one-parameter validator, the description covers purpose, cost, and network, which is the core context. Since there is no output schema, it leaves an important gap by not indicating whether the tool returns a boolean, a classification, or an error for malformed addresses.

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 0%, so the description must compensate for the undocumented address parameter. It adds meaningful constraints by specifying 0x format and Base network, but it does not clarify requiredness or provide an example address format.

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 names a specific check: validating 0x address format and determining whether the address is an EOA or contract on Base. The phrase 'before you pay' signals its relationship to the paid sibling agentready_quote, though it does not name that sibling explicitly.

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 clearly positions the tool as a free pre-check before paying, which tells the agent when to use it relative to agentready_quote. It does not state any explicit exclusions or cases where this check is unnecessary, but the context is strong for a one-parameter validator.

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

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

With no annotations, the description must carry the behavioral burden; it does disclose that the call itself is free and that it returns payment routing data (payTo, x402 URL) rather than the report itself. It says nothing about validity requirements on the address, error behavior for non-Base wallets, or whether results are cacheable, which matters for an unannotated tool.

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?

A single tight sentence with the key qualifier "Free" front-loaded, and every clause carries information (price, payTo, URL, report contents). It is dense but not padded; only the trailing parenthetical is slightly crowded.

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?

There is no output schema, so the description must describe the return value, and it does so concretely: price, payTo, and the exact x402 URL. For a single-parameter, single-purpose quote tool this is nearly sufficient, with only payment-flow mechanics and failure modes left unstated.

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?

Only one parameter exists and the schema documents it at 100% coverage ("Base/EVM 0x wallet"), so the schema already does the work. The description reinforces that the input is a wallet address and that the quote is scoped to Base, but adds no format or constraint detail beyond the schema.

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 names a specific action (quote) and enumerates the exact payload: price, payTo, and the x402 URL, plus what the eventual paid product contains (0-100 score, A-F grade, gas/USDC/activity checklist). It implicitly separates itself from agentready_check_address by being a pricing step rather than a scoring step, though it never names the sibling outright.

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?

The leading "Free:" and the mention of the URL "to buy a full ... score" imply this is the pre-purchase step that precedes agentready_check_address, so an agent can infer the flow. However, no explicit when-to-use/when-not statement or alternative tool is named, leaving the ordering to inference.

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