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

No annotations are provided, so the description carries the full disclosure burden. It usefully declares 'Read-only' and names the data sources (lightweight GMGN fundamentals and security data), but says nothing about rate limits, auth, latency, or failure behavior for one or more invalid addresses.

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?

One front-loaded sentence with zero filler; the read-only nature, the resource, and the cardinality all land immediately.

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, single-parameter, no-output-schema tool the description is adequate but thin: it does not indicate what the comparison output contains beyond a vague 'fundamentals and security data' or how results are ordered relative to the input addresses.

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% for the single 'addresses' parameter, but the schema itself enforces the 0x-address pattern and the 2–5 item bounds, which the description merely restates. No additional meaning (e.g., ordering, duplicate handling) is supplied.

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 (compare), resource (Robinhood Chain token contracts), and scope (2–5 contracts) in one clause. It clearly differentiates from siblings like agentcity_research_robinhood_token, which handles a single token rather than a comparative set.

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 2–5 cardinality constraint implies a batch/comparative scenario, but the description never says when to prefer this over research_robinhood_token or search_robinhood_token, nor any exclusions or prerequisites. Usage is inferable but not stated.

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