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

With no annotations, the description carries the full behavioral burden. It usefully discloses polling cadence and an x402 payment cost of $0.001 USDC on Base, but it does not explain error behavior, auth requirements, rate limits, or default network 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 three efficient sentences: purpose first, then polling behavior, then cost. Every sentence contributes useful information without filler.

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 read-only status tool with no output schema, the description adequately names the return statuses. However, it leaves gaps around the optional network parameter's default and the exact tx_hash input format, and the payment note only specifies Base.

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 both parameters. It mentions that the network can be Base or Ethereum, matching the enum, but gives no tx_hash format, no requirement detail, and no explanation of what happens when network is omitted.

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 states a specific verb and resource: checking a transaction's status on Base or Ethereum, with the possible outcomes pending, confirmed, or reverted. It is clear, but it does not explicitly distinguish this tool from nearby siblings such as agent-transaction-watch.

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 gives clear polling guidance: retry about every 15 seconds while pending and stop once confirmed or reverted. It does not describe when not to use the tool or name an alternative sibling, so it falls short of full when/when-not guidance.

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