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

No annotations exist, so the description carries the full burden, and it does disclose key behavior: what is returned (verified identity, on-chain price/24h/market cap/liquidity, oracle price for equities) and an important caveat that premiumPct comes from an executable Jupiter quote only 'when available'. It omits auth requirements, rate limits, and error behavior for unresolvable symbols.

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?

Front-loaded with the action and accepted inputs, then the return payload, then example use cases. The long first sentence is dense and list-heavy, but with no output schema every enumerated return field earns its place; only minor tightening is possible.

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 and no annotations, the description compensates well by describing the return payload in detail and giving usage scenarios. It is essentially complete for invocation; only peripheral details (failure modes for unknown symbols, freshness/latency of the live market data) are absent.

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 coverage is 100%, so the baseline is 3, but the description earns more by supplying concrete accepted inputs (HOODx, NVDAx, AAPLx, USDY, GOLD) that clarify the symbol-vs-mint duality and the kinds of assets in scope (tokenized equities, treasuries, commodities).

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 specific verb and resource ('Look up one tokenized real-world asset by its symbol ... or exact Solana mint') and immediately enumerates the payload categories (certified identity, live market read, oracle price / premium). The word 'one' implicitly separates it from list_rwas, and the identity/price framing separates it from performance-oriented siblings like get_rwa_performance.

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?

Gives concrete triggering questions ('how is tokenized Robinhood doing', 'is HOODx trading above the real stock') and a stated purpose ('resolve the real mint safely'), which is strong positive guidance. It stops short of naming alternatives or stating when not to use it (e.g. vs list_rwas for discovery), so it lands just below the top band.

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