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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It describes the action but does not disclose behavioral traits such as read-only nature, error handling for invalid slugs, or any side effects. The description is insufficient for a tool without annotations.

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 description is a single sentence plus a short tagline, both concise and front-loaded. Every part adds value: the core action, the scope, the output, and a usage context.

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?

Given the tool's simplicity (one parameter, no output schema), the description covers the purpose and input range. However, it lacks any detail about the output format or behavior on invalid input, which are gaps for a tool without an output schema.

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% with the 'slugs' parameter well-documented (pattern, note about search_apps). The description adds meaning beyond the schema by specifying the comparison includes metadata and review summaries, and the use case for competitor analysis.

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 the tool compares 2-5 Shopify apps side by side, listing what is compared (metadata and aggregate review summary). It distinguishes itself from siblings like get_app (single app) and get_app_reviews (reviews for one app) by specifying the comparative nature and the number of apps.

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 description includes 'Ideal for competitor analysis,' which provides context for when to use the tool. However, it does not explicitly state when not to use it or name alternative tools. The context is clear but lacks explicit exclusions.

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