Background helper for an owning Dutch tax workflow: collects and checks sourced Box 1 and own-home facts (eigen woning, eigenwoningforfait, hypotheekrenteaftrek, eigenwoningschuld), using 2025 evidence for annual workpacks and labeled 2026 estimates for the voorlopige aanslag. Use only when an active annual or provisional workflow reaches its income or own-home 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 1 And Own Home Background helper for Box 1 income and eigen woning findings. It returns facts, 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`. - **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, computer use, screen interaction, a connector, or another tool to open or operate an authenticated tax portal; never log in, enter or change values, click controls, sign, send, submit, retrieve private account data, or ask for, accept, store, or process credentials or sessions. Those actions remain …

How to install
mdr add cyanxxy/nl-tax-agent-skills/nl-tax-box1-home@sha256:ed2556876ae34fe6The 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.
