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

No annotations are provided, so the description carries the full behavioral burden and does disclose substantial context: price ($0.25 USDC), chain/token/wallet, payment_tx mechanism, latency (<200ms), and output formats. It still omits read-only/non-destructive semantics and error behavior, which prevents a 5.

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 definition is front-loaded with the report's purpose, metrics, and formats, and the payment details are relevant to invocation. It is dense but not redundant; however, the payment block slightly crowds out sibling differentiation.

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?

With no annotations and no output schema, the description must cover behavior, cost, and return content, and it does provide metrics, formats, latency, and payment mechanics. It leaves sibling selection and detailed error/return structure unaddressed, so it is strong but not complete.

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%, and the schema already documents all five parameters including the payment alternatives. The description only adds payment context for payment_tx (price and wallet) and does not add meaning beyond the schema for case_path, exercise, x_payment, or quote_id, so the baseline 3 applies.

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?

It names a specific resource, a per-exercise biomechanical report, and enumerates the report contents and intended use cases, so the agent can tell what it returns. It does not distinguish itself from sibling rehab-report tools such as get_rehab_summary, get_rehab_profile, or get_rehab_sample, which keeps it short of a 5.

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 phrase 'for PT_outcome_measurement or medical_insurance_review' provides intended-use context, but there is no explicit guidance on when to choose this tool over similar sibling tools or when not to use it. The guidance is therefore implied rather than fully actionable.

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