shopify_batch_watch

PAID ($0.03 USDC per store on Base via x402, max 50). Monitor a whole set of competitor Shopify stores in one call; per-store change counts (new/removed/price/stock). Use for tracking many rivals, category-wide price monitoring, brand/agency portfolio surveillance, market-scanning at scale.

Behavior4/5

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

With no annotations, the description carries the full behavioral burden. It discloses critical context: paid cost ($0.03 USDC per store on Base via x402), a max of 50 stores, and the shape of results (per-store change counts for new/removed/price/stock). It does not cover error handling, rate limits, or whether the operation is read-only, but the payment and output details are substantial.

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

Conciseness4/5

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

The description is two sentences and front-loads the most critical operational detail (payment requirement and max) before stating the tool's purpose and use cases. The list of use cases at the end is slightly verbose but each phrase adds a distinct scenario, and there is little wasted wording.

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

Completeness4/5

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

For a batch tool with one fully described parameter, no output schema, and no annotations, the description covers cost, limits, output format, and primary use cases. It does not explain edge cases like exceeding the max store count, but otherwise provides enough context for an agent to invoke it correctly.

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 100% for the single 'stores' parameter, and the schema itself provides a clear description and example. The tool description adds no parameter-specific details beyond what the schema already states, so the baseline score of 3 is appropriate.

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 description states a specific verb (monitor) and resource (competitor Shopify stores) and emphasizes batch scope ('whole set ... in one call'), which implicitly distinguishes it from single-store siblings. However, it does not explicitly name or contrast with any sibling tool, so differentiation is inferred rather than stated.

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

Usage Guidelines4/5

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

It provides clear use cases: tracking many rivals, category-wide price monitoring, brand/agency portfolio surveillance, market-scanning at scale. It does not include any when-not-to-use guidance or explicit alternatives, but the context for when to choose this tool over a single-store one is evident.

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