sii_oficios_por_anio

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

No annotations are provided, so the description carries the transparency burden. It does disclose non-obvious output characteristics, such as the official summary and normative reference per item and grouping by series, but it does not address pagination, limits, or other behavioral caveats. This is adequate for a read-style listing tool but not comprehensive.

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?

The description is a single front-loaded sentence with a clear verb and resource. The parentheticals add precision about series and content without unnecessary verbosity.

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 tool with one optional parameter and no output schema, the description explains the key return composition and grouping. It does not discuss ordering, limits, or empty-result behavior, but these are minor given the simple contract.

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%, so the baseline is 3. The description's phrase 'de un año' loosely maps to the anio parameter but adds no format or default information 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?

The description states a specific verb and resource: it lists SII administrative jurisprudence (oficios and Director's pronouncements) for a year, grouped by series. It also names the included content, making it easy to distinguish from search-oriented siblings like sii_buscar_resoluciones_y_oficios.

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?

The description implies the tool is appropriate when an agent needs all SII oficios for a given year grouped by series. However, it gives no explicit guidance on when to prefer it over overlapping siblings such as sii_buscar_resoluciones_y_oficios or sii_descargar_oficio, nor does it state any exclusions.

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