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

With no annotations, the description carries the full behavioral burden. It usefully discloses the data source (crypto social feeds) and chain coverage (Base and beyond), but says nothing about read-only semantics, rate limits, data freshness, or what a 'hype ratio' actually measures.

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?

Two tight sentences, with the resource described before the usage guidance, so it is well front-loaded. Minor redundancy from repeating 'meme coin' in both sentences keeps it from a 5.

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 zero-parameter, non-destructive lookup with no output schema, an agent knows what it returns (trending meme tokens plus hype ratios) and what it is for. It could still say more about the returned fields or refresh cadence, which is the only 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?

The tool takes zero parameters, so the baseline is 4; there is nothing for the description to disambiguate. The description correctly implies the tool is a fixed, no-argument snapshot call.

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 names a specific resource and output shape: trending meme tokens with hype ratios from crypto social feeds. That is far more informative than the name alone and clearly separates it from sentiment/market siblings like akari_reddit_sentiment or akari_hl_market, though no sibling is named explicitly.

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 second sentence explicitly states the use cases — meme coin momentum scanning and degen ticker discovery on Base and beyond — which gives a clear selection context. It offers no exclusions or named alternatives, so it stops short of a 5.

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