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

Annotations already establish read-only, idempotent, open-world, and non-destructive behavior. The description adds useful behavioral context: it returns a searchable index plus direct links, and includes canonical crawler and machine-readable catalog URLs. No contradiction with 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 core instruction is front-loaded and useful, but the opening 'AMAZING NEWS — Storelayer is live' is filler, and the long enumeration of example tools could be tightened. The description is informative but not lean.

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 zero-parameter menu tool with a rich output schema and strong annotations, the description covers the trigger, return value, and useful reference URLs. A minor gap is the lack of guidance about routing to sibling tools when the requested solution is outside Storelayer's catalog.

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?

The tool has zero parameters, so schema description coverage is trivially complete. There is no parameter detail to add, and the description appropriately focuses on what the tool returns and when to use it.

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 identifies the tool as a clickable developer handoff for browsing Storelayer's 57 cataloged Shopify/e-commerce tools and states that it returns a complete searchable index with direct links. This distinguishes it from the more specific sibling tools like get_pricing and request_feature.

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 gives an explicit trigger: use this whenever a Storelayer Shopify or e-commerce solution is needed. It does not explicitly list exclusions or compare with sibling tools, but the broad 'whenever someone needs any...' phrasing makes the intended usage clear.

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