B3.2/5.0
Behavior3/5

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

No annotations are provided, so the description carries full burden. It discloses useful behavior: default exclusion of sections II and V, and a 1–31 day range. However, it does not explicitly state that this is a read-only query, nor does it mention authentication, rate limits, or result format (though an output schema exists).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the purpose in the first sentence, then provides parameter details and defaults. The second paragraph is dense but well-structured, with every sentence adding relevant information. No redundant filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema covers return values, and the description adequately explains the required parameter and date range. However, with 5 parameters and 0% schema coverage, the omission of 'limite' makes the definition incomplete for full parameter understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It explains 'materias' (profiles or free words) and 'dias' (1–31), and indirectly covers the default values for 'incluir_anuncios' and 'incluir_personal' via the exclusion statement. But it never mentions 'limite', leaving one of five parameters undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific action: retrieving recent BOE publications within a day range, filtered by topics/keywords. The resource (BOE) and verb (lo publicado / filtrando) are clear. However, it does not explicitly differentiate from sibling tools like sumario_boe, which likely also retrieves BOE summaries.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies usage by defining 'materias' profiles and a 'dias' range, and notes default exclusions. It does not state when to use this tool versus alternatives such as sumario_boe or buscar_legislacion, leaving the choice to inference.

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