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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. Beyond that, the description usefully discloses the return shape (one main course with URL plus up to two alternatives), which matters because there is no output schema. It does not say what happens when no relevant course exists or whether results are ranked by score.

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 front-loaded sentence with zero filler that leads directly with the returned resource. It is efficient, though minimal enough that a short clause about fallback behavior would have been worth the space.

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 one-parameter, read-only tool with full schema coverage and annotations, the essentials are present, including a partial description of the return value. It remains incomplete on no-match behavior and on how it differs from the search and learning-path siblings.

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 100% and the single 'tema' parameter is well documented with examples in the schema. The description only restates that the input is a topic, adding no constraints or format detail beyond the schema, so baseline 3 applies.

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: returns the most relevant MIDE/Mide360 course for a topic, plus its URL and up to two alternatives. The recommendation framing is distinguishable from buscar_contenido_mide and ruta_de_aprendizaje, though it never names them explicitly to sharpen the boundary.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no mention of the sibling tools (buscar_contenido_mide, ruta_de_aprendizaje) that an agent could pick instead. The usage is only implied by the phrase 'para un tema'.

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