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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, and idempotentHint=false, so the safety profile is largely covered. The description adds genuinely useful staging semantics — the page is previewable before publish and only becomes live on merchant publish — but says nothing about duplicate-title behavior, permissions, or failure modes.

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?

Two sentences, front-loaded with the action and resource, with the lifecycle context second. Nothing is padded or repeated.

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 3-parameter nested-object tool with no output schema, the definition covers what the tool does and when the result becomes visible, but leaves out what the call returns, how duplicate pages are handled, and how the store parameter interacts with multi-store setups.

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?

Coverage is 67%, so the schema already documents the nested page.title, createCustomTemplate, and draft/store params in detail. The description still adds meaning by clarifying the template is optional and page-specific, reinforcing the createCustomTemplate flag rather than merely restating 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?

States a specific verb and resource ('Create a new Shopify page') and scopes it to a 'Fudge draft', which distinguishes it from the create_draft_article/collection/product siblings by resource noun alone. It does not explicitly name those alternatives, so it falls short of the top band.

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?

Usage is only implied: the draft lifecycle sentence ('can be previewed in the draft and goes live when the merchant publishes') tells an agent this is a staging operation, but there is no explicit when-to-use vs. when-not, no prerequisites (e.g., an existing draft, required store connection), and no guidance on choosing template options.

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