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

With no annotations, the description carries the burden and does disclose that results are 'read from chain' (i.e. a read-only, authoritative check) and names the four gates plus the 10-per-address cap. It does not cover invalid/non-BSC address handling, failure modes, or freshness/latency of the on-chain read.

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 sentence, front-loaded with verb and resource, followed by the gate enumeration. Dense but every clause names a distinct check, so nothing reads as filler; the colon-separated list is scannable.

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 one-parameter read tool with no annotations and no output schema, the enumeration of gates implicitly tells the agent what comes back, which is the main thing needed. However, no output shape, ordering, or failure behavior is described, leaving the agent to discover the result structure at call time.

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 0% and the schema only types 'address' as a string, so the description's addition of 'BSC address' supplies useful meaning (which chain the address must belong to) beyond the schema. It stops short of format details (checksum, hex length) or what happens when the address has no on-chain history.

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 ('Check') and resource ('a BSC address') and enumerates exactly what is verified: AgentGate.isEligible, trial-miner claimed, Genesis-list qualification, and Genesis mints used/remaining. That is far more specific than a sibling like genesis_status, though it never explicitly contrasts itself with those siblings.

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?

There is no explicit when-to-use statement, no prerequisites (e.g. 'call before minting'), and no mention of alternatives such as genesis_status or tier_price. An agent can infer it is a pre-mint eligibility gate, but the routing decision is left entirely to inference.

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