Sumario del BOE de un día

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

Annotations already declare readOnlyHint, idempotentHint and non-destructive behavior, and the description is consistent with them. It adds context beyond the annotations: the today default and the Sunday non-publication rule, both operationally relevant for shaping a query.

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?

Two tightly written sentences with zero waste, front-loading the core action and following with the filters and the Sunday caveat. Every clause carries information the agent needs.

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?

Adequate for a read-only list tool whose safety profile is covered by annotations, but with no output schema the description never indicates what a returned 'publicación' contains or how results relate to boe_documento for follow-up. This is a modest gap for a summarization tool.

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 coverage is 67% and the schema itself richly documents the parameters, including the YYYY-MM-DD pattern, the '*' prefix semantics, and the full section enum. The description only restates the filters at a high level and confirms the today default, adding little beyond what the schema already provides.

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 ('Lista') and resource ('publicaciones del BOE') scoped to a single day, with optional keyword and section filters. It is clearly distinct from siblings like boe_buscar (search) and boe_documento (document lookup), though it doesn't name those alternatives 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?

Gives a useful default ('por defecto, hoy') and a real usage constraint ('El BOE no se publica los domingos'), which tells the agent when a day query is futile. However, it offers no explicit guidance on when to prefer this over boe_buscar for the same retrieval task.

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