Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_tax_returnsA | List the tax years and documents available in the local folder. Returns, per year, the documents found (GeTax form, summary, supporting documents, scans) and whether a text-layer form is usable. Paths are relative to the tax folder. |
| get_tax_returnA | Return the normalized declaration for a year.
|
| compare_tax_returnsA | Compare two declarations on the recognized fields (totals + key fields). Returns the values for both years and the difference (year2 - year1). Only fields recognized with confidence are compared. |
| simulateA | Simulate the tax of a household with the official ESTV calculator. EXPLICIT parameters (no data is injected automatically from the PDFs).
|
| find_locationB | Resolve a municipality name or postal code to an ESTV tax location id (for simulate). |
| list_deductions_estvC | List the ESTV deduction sheet for a household (ids to pass to simulate). |

Scored across 6 tools
Each tool targets a distinct operation: listing available returns, retrieving a normalized declaration, comparing two declarations, listing deduction options, simulating tax, and resolving location IDs. Even the two list_* tools are clearly separated by their object.
Most tools follow a clear snake_case verb_noun pattern such as get_tax_return, list_tax_returns, and find_location. The single tool named simulate is the only mild deviation because it lacks an explicit object, but the pattern remains predictable overall.
Six tools is a well-scoped size for this domain. Each tool supports a distinct part of the tax workflow without redundancy or unnecessary surface area.
The toolset covers the full local workflow: discover available returns, retrieve normalized data, compare years, load deduction options, resolve locations, and run simulations. There are no apparent dead ends for an agent trying to analyze or estimate a household's Swiss tax situation.
