List Traders

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

The description adds 'currently following' scope, which is a behavioral constraint not covered by the readOnlyHint annotation. It doesn't describe return format or pagination, but for a no-parameter read-only tool with annotations, this is adequate.

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 a single, front-loaded sentence with zero wasted words: 'List all traders you are currently following.' It is concise and easily scannable.

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 simple list tool with no parameters, read-only annotation, and no output schema, this description is complete. It clearly states the action and the scope, leaving no ambiguity for the agent.

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?

There are zero parameters, so the schema coverage is 100% by default. The description has no parameter details to add, and the baseline for zero-param tools is 4.

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 uses a specific verb ('List') and resource ('traders') with a clear scope ('currently following'). It distinguishes itself from sibling tools like discover_traders (which lists available traders) and get_trader (which retrieves a single trader).

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 phrase 'currently following' provides context that this tool is for viewing followed traders, not for discovery or individual lookups. However, it does not explicitly name alternatives or state when not to use it, so it lacks explicit exclusions.

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