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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, open-world), so the marginal bar is met with real additions: a free tier with a per-caller daily quota, the fact that payment headers are required, and what the verdict bands and risk-code list contain. The quota and auth-channel details are exactly the operational context annotations cannot express.

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 lead sentence is well front-loaded, but the body is heavily duplicated: the same content appears in Chinese and English, then again in the [zh]/[en] vendor-asset block that restates the title, price model, and argument list verbatim. Real information density is fine, but a meaningful share of the text is repetition rather than new signal.

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 two-parameter read-only scoring tool with no output schema, the definition covers the essentials an agent needs to call it correctly: what comes back, the quota boundary, and where credentials go. The only soft spot is the slight divergence between the English output description (verdict + risk codes) and the Chinese one (which also mentions token symbol and holder count), leaving the exact return payload marginally ambiguous.

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 0%, so the description must carry the load, and it does: address is declared required, chain optional with the concrete allowed values base/eth/bsc, which the schema itself does not enumerate. It also clarifies the negative case that payment fields must never be passed as parameters, preventing a likely misuse.

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?

The description frames the tool as a direct question ('is this token a honeypot or a scam') and states the concrete output: a safe/caution/danger verdict plus a list of hit risk-code tags. That is a specific verb+resource with a described result shape. It does not name a sibling such as safety_detail_entry or safety_report, though the phrase 'enough to decide whether to keep digging or give up' implicitly signals a tiered quick-scan role.

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 context is clear: this is the free, quota-bounded quick screen used to decide whether to escalate to a deeper lookup. It also states the constraint that payment/auth belongs in MCP headers (X-Payment / X-Payment-Tx / Bearer fg_…) and must not be placed in arguments, which is genuinely actionable guidance. It stops short of explicitly naming the alternative tool for follow-up investigation.

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