cvp_breakeven__units_for_target_profit

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does not disclose any behavioral traits, such as whether the tool performs a simple formula, assumptions, or side effects. It is completely opaque.

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 only a few words, but this is under-specification rather than conciseness. It lacks structure and fails to convey essential information, wasting the opportunity to provide 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 the tool has 4 required parameters, no output schema, no annotations, and no parameter descriptions, the description is completely inadequate. It does not explain what the tool returns or how to use 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?

The schema coverage is 0% (no descriptions for parameters), and the description adds no information about the parameters. Despite the parameter names being somewhat self-explanatory, the description does not elaborate on their meaning, units, or 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 is just a restatement of the tool name: '[cvp-breakeven] units_for_target_profit'. It lacks a verb or clear statement of what the tool does. It does not distinguish from the sibling tool 'breakeven_units', which likely calculates units for zero profit, while this tool calculates units for a target profit. The description provides no such differentiation.

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 offers no guidance on when to use this tool versus alternatives. There are several sibling CVP tools (e.g., breakeven_units, contribution_margin), but no context is given to help the agent choose correctly.

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