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

With no annotations the description carries the full burden. It usefully discloses the return shape ('agrupadas por sección, con slug, título y descripción'), but says nothing about whether the listing is scoped, paginated, or how the locale parameter affects results.

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 dense sentence that front-loads the action and groups the output information compactly. Nothing is wasted or padded.

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?

There is no output schema and no annotations, so the description is the only source of behavioral detail. It covers the return structure adequately but omits the locale parameter's effect and any usage routing against siblings, leaving real gaps for a tool with this much unstated context.

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 description coverage is 0% and the single 'locale' parameter is never mentioned in the description. The enum values es/en are visible in the schema, but the description does not explain what locale changes about the returned content, leaving the one parameter undocumented.

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 ('Lista todas las páginas de la documentación') plus the grouping and returned fields, so the operation is unambiguous. It does not, however, distinguish itself from the sibling search_docs, which also retrieves documentation content.

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?

No indication of when to use this versus search_docs or read_doc. The agent must infer that this is the exhaustive listing tool while search_docs is for queries, and no such routing guidance is given.

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