Get Profit And Loss

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds little beyond the period scoping; it does not disclose response structure, default date behavior, or calculation specifics, but it also does not contradict the annotations.

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 no filler. Each term adds meaning: the tool name, the income-statement clarification, and the period scope. It is appropriately concise, though it could have packed in more useful guidance without becoming verbose.

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 read-only report with two well-documented date parameters, the minimal description is mostly sufficient when combined with annotations. However, with no output schema and both parameters optional, the agent is left to infer default behavior and return format, which is a notable gap.

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?

Schema description coverage is 100%, with from_date and to_date already documented as YYYY-MM-DD strings. The description's 'for a period' aligns with these parameters but adds no extra semantics such as defaults, requiredness implications, or range constraints.

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 specific verb and resource: 'Get Profit and Loss (income statement) report for a period.' The parenthetical synonym and time scope make the tool's purpose unambiguous and help distinguish it from related report tools like get_balance_sheet or get_trial_balance, though it does not explicitly name those siblings.

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?

Usage is only implied: the phrase 'for a period' suggests this tool is for income statement reporting over a date range. There is no explicit guidance on when to choose this tool over the many financial-report siblings, nor any exclusions or alternative suggestions.

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