ecommerce_safety_guard

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not state whether the tool is read-only, what it returns (e.g., boolean, error), whether it blocks updates, or the nature of the 'safety' check. The only hint is that it checks 'price difference', but details on thresholds and failure handling are missing.

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?

A single concise sentence that front-loads the core purpose without any fluff. It is appropriately brief, though it sacrifices necessary details for brevity.

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 validation tool with no annotations and no output schema, the description is incomplete. It lacks crucial details such as return values, error behavior, side effects, and how the safety check is calculated, leaving an agent uncertain how to interpret results or handle failures.

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 explain the parameters, but it does not. It vaguely references 'price difference' (relating to currentPrice and proposedPrice) and 'safety' (likely maxPriceDropPercent), but provides no explicit mapping or additional meaning beyond the parameter names themselves.

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 clearly states a pre-update safety check for product prices, using the verb 'ตรวจสอบ' (check) with a specific resource (product price before update). It conveys a guard-like role, distinguishing it from actual update tools like ecommerce_update_price_stock, but it does not explicitly name the sibling it complements.

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 'before performing the actual update' implies this should be used prior to update tools, but it does not explicitly name alternatives like ecommerce_update_price_stock or state when not to use it. The usage context is clear but not fully explicit.

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