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

With no annotations, the description carries the full behavioral burden and does disclose meaningful traits: a fixed cost ($0.0050 USDC per call), the x402 payment protocol, the POST endpoint, and that data is returned directly. It omits rate limits and error behavior, so it is strong but not exhaustive.

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 functional summary is front-loaded and the pricing/execution details are cleanly separated by a delimiter, so key info is easy to scan. It is slightly verbose and the trailing 'data/langsung' is cryptic, keeping it short of a 5.

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 single-parameter tool with no output schema or annotations, the description supplies the returned fields, input convention, cost, and execution endpoint, which is enough to call it correctly. Deeper detail on response shape or failures is the only gap.

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 the single 'token' parameter. The description only restates the comma-separated symbol/mint convention already present in the schema, adding no new meaning, which fits the baseline of 3.

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 resource (token) and enumerates the returned fields (USD price, liquidity, 24h change, decimals), so an agent knows exactly what it fetches. It does not, however, explicitly contrast itself with sibling crypto tools like banding-token, quote, or tokens-baru, leaving differentiation to inference.

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?

Usage is only implied: the description gives the input format (symbol or mint, comma-separated) but never states when to prefer this over banding-token, quote, or trending. No exclusions or prerequisites are offered, so the agent must infer the right context.

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