Prepares a draft 2025 or 2026 Dutch opgaaf ICP (intracommunautaire prestaties, EU sales listing) for one period: EU business customers by alias and VAT-ID check, goods versus services, corrections to earlier periods, and reconciliation with rubriek 3b of the btw-aangifte.

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 ICP Prepare one evidence-linked ICP workpack for a Netherlands-established eenmanszaak/ZZP and one confirmed 2025/2026 declaration period.

Never use a browser, Claude in Chrome, computer use, screen interaction, a connector or another tool to open or operate it; never log in, enter/change values, click controls, sign, send, submit or retrieve private account data.

If someone other than the taxpayer will review or file, read the authorization section of `../nl-tax-shared-resources/knowledge/vat/return-and-rubrics.md` and add its authorization-check reminder; never collect credentials. - **Conversation first.** Write nothing without current-session save consent. The only output file is `workspace/nl-tax-icp-<year>-<period>-workpack.md`. …

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.
