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

No annotations are provided, so the description carries the full burden, and it does disclose the key non-obvious behavior: a first call without payment_proof returns payment information, and the call must be retried with proof, or a license_key can bypass it. This is genuinely important auth/payment context. It omits other traits such as whether the analysis is deterministic or how long the report is, keeping it out of 5 territory.

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?

Purpose is front-loaded in the first sentence, followed by a clean per-argument breakdown using the standard Args convention. Every section earns its place, though the payment paragraph repeats the license/payment relationship slightly.

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?

An output schema exists, so return values need not be described, and the description covers the invocation flow, parameter semantics, and the payment gate. The main gap is the absence of trigger conditions relative to sibling tools, which is the only missing piece for calling 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 description coverage is 0%, so the description must compensate, and it does: each of the five parameters is explained with meaning plus a concrete example (e.g. the '3号注塑机' problem sample, quantified data, target threshold). It also clarifies that payment_proof and license_key are alternatives, resolving the mutual-exclusivity that the bare schema cannot express.

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 names a specific verb+resource: analyzes a management/equipment/quality problem using named methodologies (Toyota 8-step, 5Why three layers, 8×4 matrix) and emits a full analysis report. That is concrete and actionable. It stops short of explicitly distinguishing itself from siblings such as quality_management or device_management, so it is clear but not fully differentiated.

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?

There is no guidance on when to choose this tool over the sibling tools (quality_management, device_management, cost_improvement), which are the obvious overlaps for a TBP analysis. The payment instructions describe an invocation flow but not selection criteria, so usage must be inferred.

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