Massachusetts pack: Massachusetts statute plus Supreme Judicial Court, Appeals Court and trial precedent. Bluebook with the Anthony's Pier Four exemplar, malegislature General Laws source, covenant/93A/data-security retrieval rule, and the shared risk block. Read when a matter is governed by Massachusetts law.

This matter is governed by the law of Massachusetts (United States). Reason and write to that jurisdiction.

- Primary authority is Massachusetts statute and the binding precedent of Massachusetts courts (Supreme Judicial Court, Appeals Court, trial courts). Federal law applies within its own sphere. - The `case-law` tool covers U.S. federal and state opinions. Verify a decision is from Massachusetts courts (or a federal court applying Massachusetts law) before presenting it as binding; other states' decisions are persuasive only. - When the binding position turns on a Massachusetts statute or decision you have not retrieved, say so plainly rather than generalizing from other states. - Substantive conclusions require verification by counsel admitted in Massachusetts. - Cite to Bluebook, e.g. *Anthony's Pier Four, Inc. v. HBC Assocs.*, 411 Mass. 451 (1991). Statutes: Massachusetts General Laws chapter and section (e.g. G.L. c. 93A). - Matter documents keep the existing `[ §

]` form. - Current Massachusetts General Laws text is at `https://malegislature.gov/Laws/GeneralLaws`. Follow the legal-research skill: retrieve before relying.

Jurisdiction is a risk-calibration axis. Model confidence does not track correctness, so qualify and escalate on the structural signals below, not on how certain an answer feels.

Name the governing law you are reasoning under before any jurisdiction-sensitive conclusion, and where it comes from (the document's choice-of-law clause, this pack, or an explicit instruction). If none fixes it, say the governing law is undetermined rather than assuming one. Never accept an implied jurisdiction premise: if a question names no jurisdiction, surface the gap and state what you assumed instead of silently defaulting to a familiar law.
Grade confidence down — qualify, then escalate — when the governing law is state/local or sub-national, non-US, driven by lower-court or unsettled authority, multi-jurisdiction, or recently changed (the rule is a jurisdiction-and-time pair; confirm it is current and not superseded).
Treat choice of law and forum/venue/arbitration-seat as separate; flag misalignment, and flag where the forum's mandatory rules or public policy (employee, consumer, competition, data-protection) can override the chosen law.
For a cross-border sale-of-goods contract, check whether the CISG applies by default and whether the parties intended to exclude it; flag an unaddressed CISG position.
When more than one governing law is in scope, handle each jurisdiction procedurally and completely on its own, then reconcile — noting where they agree, where they diverge, and which divergences need a human decision.
