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

With no annotations, the description must carry the behavioral disclosure. It does disclose the returned content categories and sortable metrics, which is useful. However, it does not describe ordering defaults, the meaning of the 'stocks' flag, whether results are aggregated or per-wallet, pagination, or any side effects or limitations.

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?

A single sentence conveys both the resource's content and its sort options, with the core identity front-loaded. It is compact and wastes no words, though it relies on a noun-phrase style rather than a verb-led action statement.

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?

Given 4 parameters, no annotations, and no output schema, the description should provide more context: what 'stocks' controls, what window does, what the result shape looks like, and how this leaderboard differs from similar talon tools. The current text gives a good high-level summary but leaves too many operational details unstated.

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 description adds meaning to the sort parameter by explicitly enumerating valid values and indicates the domain of the data, compensating somewhat for 0% schema description coverage. But it leaves limit, stocks, and window semantics to inference from names and defaults, which is incomplete for an agent.

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 clearly identifies a leaderboard for FOMO traders and lists the metrics it exposes (hit rate, P/L, volume, open bags), so an agent can tell what resource is involved. It lacks an explicit retrieval verb and does not contrast with closely named siblings like talon_trader or talon_wallet, so it falls short of a 5.

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?

There is no guidance on when to choose this tool over the many sibling talon_* tools, no mention of exclusions, and no alternative names. The description simply states what it provides, leaving the selection criteria to the agent.

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