Binance Smart Chain: isFourMemeToken

isFourMemeToken
Read-onlyIdempotent

Check if a BSC token contract is registered on FourMeme and still on the bonding curve, returning the token record if found.

Instructions

Check whether a BSC token contract is registered on FourMeme and is still on the bonding curve (not yet listed / migrated off the curve). Returns the FourMeme token record if found.

Behavior4/5

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

Annotations already indicate safe, read-only behavior (readOnlyHint, destructiveHint, idempotentHint). The description adds behavioral details: it returns a record only if the token is on the bonding curve, and clarifies the scope of the check. No contradictions with annotations.

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

Conciseness5/5

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

The description is two sentences with no redundant information. It front-loads the core purpose and efficiently conveys the condition and return value.

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

Completeness5/5

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

Given the tool's simplicity (one parameter, no output schema) and rich annotations, the description fully covers the necessary context: what it checks, the condition, and the return. No gaps remain.

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

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema provides 100% coverage for the single parameter, including a description. The tool description does not add additional meaning beyond what the schema already offers, so baseline score of 3 is appropriate.

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

Purpose5/5

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

The description clearly states the tool's purpose: checking if a BSC token is registered on FourMeme and still on the bonding curve. It specifies the return value (FourMeme token record) and distinguishes from sibling tool 'bscfindMemeCoinsViaFourMeme' which targets meme coin discovery.

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

Usage Guidelines3/5

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

The description implies usage for verification of a specific token but does not explicitly state when to use this tool over alternatives, nor does it provide when-not or exclusion criteria. The sibling context suggests different use cases, but the description itself lacks direct guidance.

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