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
# Customs — Duty Optimization (Opportunity Cost) > **Industry front door for [opportunity-cost](../opportunity-cost/SKILL.md).** Adds domain triggers, example, packs only. Parent Process unchanged. > **Not legal advice.** Each program has strict eligibility; verify with counsel/CBP before relying on savings. **Activate when:** an importer has recurring, material duty spend; evaluating FTZ, duty drawback, first-sale valuation, bonded warehouse, or FTA use; "are we leaving duty savings on the table?" **Do NOT activate when:** de minimis / trivial duty where program cost exceeds benefit. ## Why this variant The parent [opportunity-cost](../opportunity-cost/SKILL.md) measures the value of the best foregone alternative. Every duty dollar paid when a lawful program would have avoided/deferred it is a foregone saving. This surfaces those foregone alternatives and sizes them against setup cost. ## Domain inputs → parent's Process Enumerate lawful alternatives and their net value vs status quo: - **Duty drawback:** refund on duties for re-exported/destroyed goods (up to 99%). - **Foreign-Trade Zone (FTZ):** defer/reduce/eliminate duty; inverted-tariff benefit. …

How to install
mdr add deciqai/knowledge-skills/customs-duty-optimization-opportunity-cost@sha256:d7d6aa5d4b2df246The line at the top of this page pins the label git:20261025.cb4e537, 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.
