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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered and there is no contradiction. The description itself adds no further behavioral context, such as ranking criteria, ordering, or pagination behavior, but the read-only annotation lowers the burden on the prose.

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 description is extremely short, but this brevity reflects under-specification rather than efficient writing. It lacks a main verb and does not clarify what kind of ranked data is returned; a slightly longer front-loaded sentence would earn the space.

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 tool with no output schema, the description should clarify what the leaderboard contains and how limit affects results. The ambiguous 'trader or token' phrasing and the absence of any return-shape or ordering information leave an agent without enough context to invoke it confidently.

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 description adds no parameter semantics, but the schema supplies a detailed authCode contract and a default value for limit. With only two parameters and 50% schema coverage, the missing limit description is largely self-evident, so this is adequate but not exemplary.

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 identifies a leaderboard resource with 'OrbitX / OG DEX trader or token' scope, which is more than a pure restatement of the name. However, it is a noun fragment rather than a clear verb+resource statement, and the slash leaves ambiguity about whether this returns a trader leaderboard, a token leaderboard, or both. It also does not differentiate itself from sibling tools like page_leaderboard or other OrbitX list-style tools.

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?

No guidance is given on when to use this tool versus alternatives. The description does not state context, exclusions, or point to any sibling such as page_leaderboard, orbitx__orbitx_get_kols, or orbitx__orbitx_get_signals.

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