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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the return value is a direct panel link scoped to a section, but says nothing about link format, expiry, or whether the store must exist first — acceptable given the rich 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?

Two short sentences with the core action front-loaded and zero padding. Every clause earns its place, with the routing hint placed after the primary purpose statement.

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 simple read-only link getter with two parameters and no output schema, the description is sufficient to invoke correctly. Minor gaps: it does not describe the returned link's form or behavior when store_id is invalid, but these are low-risk for this tool type.

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 coverage is 50%: store_id is documented in the schema, and 'section' has no schema description but uses a self-explanatory enum of seven Spanish section names. The description only restates that the link points to 'la sección elegida', adding little beyond the schema.

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 ('Devuelve el enlace directo al panel de la tienda') plus scope ('a la sección elegida'). The second sentence clarifies the tool's role in the workflow: directing the merchant to the panel for payments/shipping instead of handling them in chat.

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 note that 'los cobros y los envíos se configuran en el panel, no por el chat' gives real when-to-use context and rules out attempting configuration in chat. It does not explain how to choose among the enum sections or name which sibling to prefer for other store queries, so this stops short of 5.

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