TDQS

A3.8/5.0
Behavior4/5

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

With no annotations, the description carries the full behavioral burden, and it does substantial work: it discloses the authentication requirement (ChainHelix API key as bearer token), the pay-per-call alternative with specific payment rails, and the exact data categories returned. It does not mention rate limits or explicitly confirm read-only behavior, but for a data query tool this is a strong disclosure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description packs substantial information into a compact block without fluff. The auth/payment detail is front-loaded and the parameter semantics are clearly stated, though a bit dense as one continuous paragraph; minor formatting improvements would make it easier to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the output schema exists, the description does not need to explain return structure. It covers access requirements, parameter semantics, and data scope. The only real gap is the absence of explicit when-to-use guidance relative to sibling flow tools, but the tool is otherwise fully callable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

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, and it does. It explains the l2 parameter by listing arbitrum, base, and optimism and noting omission returns all three, and it explains window in hours with default and maximum values. This is exactly the semantic detail the schema lacks.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the resource: layer-two bridge activity for arbitrum, base, and optimism, listing concrete metrics like deposits, withdrawals, message counts, and value moved in ETH. It does not use an explicit verb like 'get' or 'list', and it does not name sibling tools, but the resource and scope are unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to choose this tool over alternatives such as stablecoin_flows or whale_flows. The only usage instruction is parameter-level: 'window in hours, default 24, max 720' and 'Omit l2 for all three', which is helpful for invoking the tool but not for tool selection.

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