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

With no annotations, the description carries full disclosure burden. It discloses the paid nature and accepted payment methods, but leaves critical ambiguity: whether the tool executes a trade or only queries, how payment is processed, and any side effects. The operational flow is unclear.

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?

Two sentences with no redundancy. The primary function is front-loaded, and the payment detail is included as a second sentence. Efficient and well-structured.

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?

Significant gaps remain: no output schema, no mention of return format, no explanation of how 'best' is determined, and no clarity on the payment flow (when and how payment is taken). For a paid service with no annotations, this is insufficient for an agent to call it confidently.

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 description restates the parameters but adds little beyond the schema. Schema coverage is 67%, and the description partially compensates by echoing 'asset, AUD amount, and buy or sell direction', but it does not clarify edge cases, formats, or constraints beyond what the schema already provides.

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 clear action ('find the best Australian cryptocurrency exchange') with specific parameters (asset, AUD amount, direction). The purpose is unambiguous, but it does not explicitly contrast with the sibling tool find_where_to_buy_crypto, so it stops short of full differentiation.

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?

Provides no guidance on when to use this tool versus the sibling. The paid-service mention implies a cost barrier but does not state conditions, prerequisites, or exclusions. An agent has no basis to choose this over find_where_to_buy_crypto.

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?

The description discloses that this is a paid service supporting XRP and USDC payments, which is important behavioral context. However, with no annotations provided, it does not disclose other behavioral traits such as whether it performs network calls, rate limits, or what happens on payment failure. The paid nature is a key addition, but more transparency about side effects would be valuable.

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 concise and front-loaded with the core purpose, followed by the payment details. It is two sentences with no wasted words, though the payment details could be seen as secondary to the main function. Overall, it is well-structured and efficient.

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?

The description covers the main purpose and payment method, but lacks details on the output format, error handling, or prerequisites (e.g., needing a wallet for payment). Given the tool's complexity (paid service, multiple payment networks), more context about the expected outcome and any required setup would improve completeness.

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%, so the schema already documents both parameters. The description adds context that the amount is in Australian dollars and the symbol is a cryptocurrency, but these are already in the schema. It does not add significant new meaning beyond the schema, so a baseline of 3 is appropriate.

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 clearly states the tool's function: finding Australian exchanges that offer a cryptocurrency and comparing live pricing, fees, spreads, and estimated outcomes. It distinguishes itself from the sibling tool by focusing on a specific cryptocurrency symbol and comparison features, making its purpose unambiguous.

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 description implies usage for comparing exchange options for a given cryptocurrency, and the sibling tool 'find_best_australian_exchange' suggests an alternative for finding the best exchange overall. However, it does not explicitly state when to use this tool versus the sibling, leaving some inference to the agent.

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