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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered structurally. The description adds real value with 'agrupados por categoría', telling the agent the response is grouped rather than a flat list. It does not say whether results are scoped to the current account/brand or what an empty Space returns.

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 sentence that front-loads the resource and closes with the intended use case — no filler. The parenthetical item list is dense but earns its place by telling the agent what content types to expect.

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-argument read tool with annotations covering safety and no output schema, the description covers what is returned, how it is organized (by category), and why you would call it. Minor gaps remain around account/workspace scoping and result ordering, which an agent might reasonably wonder about.

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 there is nothing for the description to disambiguate; the schema is trivially complete. Baseline 4 applies, with no parameter-level claims needed or missing.

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 names the resource (saved texts of the Space) and enumerates what those texts are (hashtags, calls to action, signatures, links), so an agent knows exactly what comes back. It is clearly distinct from create_saved_text/update_saved_text/delete_saved_text by being a retrieval of the existing collection, though it never names those siblings explicitly.

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 trailing clause 'para reutilizarlos al escribir publicaciones' implies the when-to-use context: fetching reusable snippets before composing a post. There is no explicit when-not guidance and no alternative tool named (e.g. get_brand_manual or get_draft_writing_instructions for other writing aids), so the routing guidance is only implied.

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