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

No annotations provided, so description carries the full burden. It clearly states the operation is read-only and returns highlights and direct links for today's 4 sections. No side effects or requirements are mentioned, but the simplicity of a parameterless tool makes this sufficient.

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?

Single sentence, concise and front-loaded. Every word adds value; no filler.

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 parameterless tool, the description gives enough context to decide to use it for today's overview. No output schema exists, but the return format (highlights and links) is implied. Complete enough given the domain and sibling tools.

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?

Input schema has zero parameters, so description does not need to add parameter info. Baseline for 0 parameters is 4. The description adds no extra parameter semantics, but none are needed.

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 clearly states the tool obtains highlights and direct PDF links for each of the 4 sections of today's Official Gazette, using a specific verb ('obtiene') and resource ('portada'). It distinguishes from siblings like obtener_enlace_pdf (single PDF link) and obtener_sumario_del_dia (summary 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 explicit guidance on when to use this tool vs alternatives. It implies it's for a daily overview, but does not state when not to use it (e.g., for specific sections or other dates). The zero-parameter nature makes usage straightforward, but guidelines are missing.

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