Terrace account

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

readOnlyHint already declares the safety profile; the description adds that results are scoped to Monad testnet and lists what data comes back (balances, cap), which is real behavioral context. It stops short of stating whether balances are freshly fetched or cached, or the units/format of the balances.

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 front-loaded sentence with no filler. It leads with what the tool is and immediately enumerates what it returns; every clause carries 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?

With no output schema, the description must cover return values, and it does list the fields. Minor gaps remain: units/format for balances and whether the per-bet cap is a limit or a current setting are not stated, though the omission is small for such a simple read tool.

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 takes no parameters, so the baseline is 4. The description correctly requires no input and instead uses its space to describe the output contents.

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 the resource precisely (this agent's Terrace account) and enumerates the fields returned: address, test-dollar and gas balances, per-bet cap. That distinguishes it from sibling tools like terrace_my_bets or terrace_matches, though there's no explicit verb ("returns" / "fetches") marking it as a read.

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 purpose implies usage — fetch it to learn the address, balances or per-bet cap — but there is no explicit statement of when to call it versus alternatives, nor any prerequisite or trigger condition. For a zero-parameter info tool this is largely self-evident, hence 3 rather than lower.

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