B3.2/5.0

Behavior4/5

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

Annotations already establish this as a safe read-only, idempotent, closed-world computation. The description adds genuinely new context not in annotations: the $0.10 USD per-call price, the x402 payment flow, and the critical fact that an unpaid MCP call returns payment instructions rather than a result. That payment/auth behavior is the kind of disclosure annotations cannot carry.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded, but the 'When:' and 'Selection:' sentences are template artifacts that repeat the tool name twice and consume space without conveying information. The unique payment information is buried after the filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described, and the schema covers most parameters. Combined with the payment disclosure, the definition is serviceable, but it leaves the agent without any real guidance on when this tool beats its many financial-analysis siblings.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 80%, so the schema already documents each OMR parameter, its bounds, and the integer-baisa internal calculation. The description only says 'from supplied fixed and variable costs' and 'see the schema', adding no format, unit, or default semantics beyond what is already structured. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening sentence states a specific verb and resource: 'Calculate break-even and target-profit units from supplied fixed and variable costs.' It is distinguishable from siblings like product_pricing_calculator or monthly_business_financial_report, though it never explicitly names an alternative to differentiate against.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'When:' and 'Selection:' lines are circular boilerplate that restate the tool name ('Use when an agent needs the Creative Techno book framework for break even calculator') without stating a real condition, prerequisite, or excluded case. The only actionable routing hint is the pointer to preview_capability, which concerns payment rather than tool selection.

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