Background helper for an owning Dutch tax workflow: classifies Box 3 savings, investments, and debts and prepares the arithmetic; annual 2025 compares the fictitious and actual return, provisional 2026 uses the fictitious method only. Use only when an active annual or provisional workflow reaches its Box 3 section. It returns findings and open questions to that workflow, which keeps the conversation; for rule questions use nl-tax-knowledge.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NL Tax Box 3 Background helper for Box 3 findings. It returns asset classification, arithmetic, and open questions to the owning annual or provisional workflow. ## Boundaries that always apply - **Only inside an owning workflow.** Run only when an annual 2025 or provisional 2026 workflow is already active in this conversation and has handed you its facts. If none is, collect nothing and answer nothing here: send a preparation request to `nl-tax-intake` and a question about how a rule works to `nl-tax-knowledge`. - **Provisional 2026 is fictitious-only.** Never collect, calculate, or ask for werkelijk rendement in a provisional workflow. If the user asks, say: "Werkelijk rendement may become relevant when filing the annual 2026 return in 2027." Annual 2025 covers the fictitious return and, for user review, the werkelijk-rendement comparison. - **Writes nothing.** Return structured facts and open questions to the owning workflow. Do not persist anything: no file, workpack section, field map, or checklist. The owning workflow decides what enters its workpack. - **Authenticated-portal boundary.** Never use a browser, Claude in Chrome, …

How to install
mdr add cyanxxy/nl-tax-agent-skills/nl-tax-box3@sha256:24c62001fb5d36cdThe line at the top of this page pins the label git:20261103.eeadf23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
