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

With no annotations, the description carries the full burden and does a decent job: it discloses concrete thresholds (25 holders, >50% single wallet, <$1,000 pool), the degraded-result behavior ('HOLD when the check did not run'), and the cost/payment model ($0.02 Base USDC via x402 GET endpoint). Missing is any statement of latency, data freshness, or whether the underlying signals are simulated on-chain reads.

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-loads the core question and the output vocabulary, then layers decision rules and pricing. Sentences are dense but each carries information; the telegraphic fragments ('$0.02 Base USDC.') trade polish for density, which is acceptable here.

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 no-annotation, no-output-schema tool with two simple params, the description covers outcome values, decision thresholds, failure mode, and payment requirements. It does not describe the shape of the response beyond the 'action' field (e.g. reasons, scores, timestamp), which is the main remaining 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 coverage is 100%, so the baseline is 3. The description adds the constraint that the token must be a Base 0x contract address, which sharpens the 'token' param beyond the schema's generic '0x…' text, but the optional 'chain' parameter (base/ethereum) is never mentioned in the description, leaving a slight mismatch with the stated Base-only framing.

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?

Opening question plus explicit output vocabulary ('action is GO, HOLD, or STOP') makes it clear this tool renders a trade verdict on a token contract. It also scopes itself away from a neighboring concept with 'Not a honeypot simulation.' It stops short of naming the obvious sibling (lion_token_risk_indicators), so an agent must infer the split.

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 STOP/HOLD criteria give implied guidance on when a verdict triggers, and 'HOLD when the check did not run' covers a fallback situation. But there is no explicit statement of when to call this versus lion_token_risk_indicators or lion_wallet_screen, and no prerequisites (e.g. supported chains) before invoking it.

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