get_profit_stats

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

The description indicates a read-only operation ('Retrieve'), which aligns with the tool's nature. However, with no annotations provided, it lacks details on data freshness, caching, or any side effects. The minimal disclosure is acceptable for a simple retrieval tool but could be improved.

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?

Single sentence that front-loads the action and lists key metrics. No unnecessary words, every part adds value.

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 no parameters and no output schema, the description lists the expected statistics, making it fairly complete. It does not explain the return format or pagination, but for a simple stats tool, this is adequate.

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 no parameters, so the description does not need to add parameter-level detail. It lists some return fields, which provides context beyond the schema. With 0 parameters and 100% schema coverage, baseline 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?

Description clearly states the tool retrieves profit and loss statistics and lists several specific metrics (total profit, win/loss ratio, etc.). This makes the purpose clear, but it does not explicitly differentiate from the sibling tool 'get_performance', which may have overlapping functionality.

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 on when to use this tool versus alternatives like 'get_balance' or 'get_performance'. The description does not provide context on prerequisites, timing, or exclusion criteria.

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