chain_radar

What is hot on a specific chain right now. Top tokens by volume with momentum scores. Perfect for Solana, Base, Ethereum, BSC scouting.

TDQS

B3.3/5.0
Behavior2/5

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

No annotations are present, so the description must carry the full transparency burden. It mentions 'right now' implying real-time results, but provides no detail on safety, rate limits, response format, or potential side effects. The behavior is minimally disclosed, which is insufficient for a tool with no other context.

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 short, efficient sentences. The first states the core function; the second lists supported chains. There is no filler or redundancy, and the most important information is front-loaded.

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

Completeness3/5

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

Given the simplicity of the tool (only two optional params, no output schema), the description conveys the general output (top tokens with momentum scores) and likely use cases. However, it lacks details on result structure, default behavior, and how it differs from related tools, leaving some gaps for a complete understanding.

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?

Schema description coverage is 100%, as both parameters (chain and limit) already have descriptions and defaults. The description adds no extra parameter semantics but doesn't need to, given the thorough schema.

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

Purpose4/5

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

The description clearly states what the tool does: shows top tokens by volume with momentum scores on a specific chain. It distinguishes this from sibling tools like momentum_score or token_scan by emphasizing chain-level scouting for Solana, Base, Ethereum, and BSC.

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 suggests a use case (scouting these chains) but does not explicitly contrast with sibling tools or state when to prefer this over alternatives. It implies usage for finding trending tokens on a chain, but lacks exclusions or comparative guidance.

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