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

With no annotations, the description carries the full disclosure burden. It reveals the HTTP method and parameter formats, but it does not state whether the operation is read-only, what the response contains, or any data-scope limitations. Since the name and 'income statement' imply retrieval, it is not misleading, just incomplete on return behavior.

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?

Three short sentences with no filler: the first identifies the resource, the second defines the two required parameters, and the third notes the optional filter. Information is front-loaded and every sentence contributes.

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 report endpoint, all request parameters and their semantics are covered, and no output schema exists to shift that burden. The main gap is not describing the response shape or content, but the tool name and 'P&L' label provide enough context for an agent to select and invoke it correctly.

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 coverage is 100%, so the baseline is 3. The description adds ISO date format and clarifies periodCount as months back, but the schema descriptions already convey these meanings; 'Optional departmentFilter' adds only minor value beyond the schema's optional field.

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 identifies the tool as an income statement / P&L report and provides the concrete endpoint, making the resource and operation clear. This differentiates it from sibling report tools such as sales, purchase, inventory, and balance reports by financial statement type.

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 opening phrase 'Income statement / P&L' provides clear context for when to use the tool: when a profit-and-loss or income statement report is requested. It does not explicitly list alternatives or say when not to use sibling report tools, but the unique P&L label makes the intended use evident.

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