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 without the description. The description adds the useful scoping fact that only stores created by this person via this path are returned, but says nothing about ordering, pagination, or result shape for an unpaginated-list tool.

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?

A single short sentence with no filler and the resource front-loaded. It is efficient, though the trailing phrase "por este camino" costs clarity rather than earning it.

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 read-only list with no output schema, an agent still needs to know roughly what comes back and whether the list is complete or paginated. The definition covers scope but leaves the meaning of "este camino" and the return contents unstated.

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 takes zero parameters, so the baseline is 4; the description correctly implies a no-argument, self-scoped operation with no filtering options an agent might look for.

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 concrete verb and resource ("Lista las tiendas") with a personal scope ("que esta persona creó"). It is distinguishable from write-side siblings like create_store or preview_store, but the qualifying clause "por este camino" is vague and only the title hints that the path is AI-created stores.

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 intent to enumerate the caller's own stores is implied by "esta persona" and "mis tiendas", but there is no explicit when-to-use guidance, no mention of when to prefer get_store_status or get_panel_link instead, and no note on what an empty result means.

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