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

With no annotations provided, the description carries the full burden. It discloses the data scope ('last ~50 graded picks') and access requirements ('No auth, no payment'), which are key behavioral traits. It implies a read-only operation but does not explicitly state safety or side-effect guarantees, which is a minor gap.

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 two concise sentences, front-loading the main purpose ('FREE — the public verifiable track record') and then listing key contents. Every phrase adds value; no filler or repetition.

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 the tool's simplicity (no params, no output schema), the description is largely complete. It covers what data is returned and the access model. It does not specify the exact response format or potential limitations beyond 'last ~50', but that is likely acceptable for a simple data-retrieval tool.

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 has zero parameters and an empty schema, so there is no parameter semantics to clarify. The baseline is 4 for no params, and the description does not need to add anything. It does not confuse by mentioning parameters.

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 states what the tool provides: a public verifiable track record with graded picks, win rate, R-multiple ROI, calibration buckets, and last ~50 graded picks. It uses a specific resource ('track record') and lists concrete contents, distinguishing it from sibling tools like analysis or signals.

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 description gives clear context: this is a free, public resource requiring no authentication. This implies when to use it (when you need public track record data without credentials) but does not explicitly mention alternatives or when not to use it. Still, the 'no auth, no payment' note provides practical guidance.

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