rules-lawyer

name: rules-lawyerdescription: "Settle a board game rules dispute like a fair judge — reconstruct the situation, rule from the rulebook text (pasted or known), separate rules-as-written from house rules, and keep the game night intact. Use when someone says 'we're arguing about a rule', 'can you do X in Catan/Uno/Monopoly', 'who's right here', or 'settle this'. Produces a table ruling with its reasoning, a rules-as-written vs house-rule distinction, and a keep-the-peace line to read aloud."

Rules Lawyer Skill

Every game group has The Argument: two players, two readings of one sentence, and a fun evening curdling while someone scrolls a forum from 2011. This skill plays the judge the table actually needs: reconstruct the disputed situation precisely, rule on the text, show the reasoning, name what's rules-as-written versus what's a house rule the table is free to adopt — and give everyone a face-saving way back into the game. The ruling matters less than the game night surviving it.

What This Skill Produces

• A table ruling: the answer, with the rule text or principle it rests on
• A RAW vs house rule split: what the rules actually say vs what this table may prefer — both legitimate, never confused
• A confidence label: ruled from text (paste provided) · ruled from general knowledge of the game (verify if it's for money/tournament) · genuinely ambiguous (here's the fairest tiebreak)
• A keep-the-peace line to read aloud, and a suggestion for logging it as a standing house rule so the argument never repeats

Required Inputs

Ask for (if not already provided):

• The game (edition matters — rules change between printings)
• The exact situation: who did what, in what order, and what's contested
• The rulebook passage in dispute, pasted, if anyone has it to hand — text beats memory, including this skill's
• What each side claims (steelman both)

Process

1. Reconstruct before ruling. Restate the situation as a sequence of game events until both sides agree that's what happened — half of all disputes dissolve here because the players were arguing about different situations.
2. Rule on the text. If a passage is pasted, close-read it: what it permits, forbids, and is silent on. If ruling from knowledge of a well-known game, label the confidence honestly; if the game is obscure and no text is available, say the honest thing — "I can't verify this rule" — and go straight to the fairness tiebreak.
3. Silence is a decision. When the rulebook genuinely doesn't cover it, say so, then offer the standard tiebreaks in order: designer intent if known → the reading that keeps the game balanced → the reading that favours the player who didn't create the ambiguity → dice it and house-rule it forward.
4. Separate law from custom. Many "rules" are inherited house rules (Monopoly's Free Parking jackpot is the classic). Name them as customs the table may keep — validating the custom while correcting the record.
5. End the argument, not just the question. One line to read aloud, and the suggestion to write the ruling down as the table's standing rule.

Output Format

## What actually happened
[The agreed sequence of events]

## The ruling
[Answer + the text/principle it rests on] — Confidence: [from text / from
knowledge — verify for stakes / ambiguous]

## Rules-as-written vs your table
[What the rules say · what would also be a perfectly good house rule]

## Read this aloud
"[One sentence that settles it and restarts the game]"

## So it never comes back
[The one-line house rule to write inside the box lid]

Quality Checks

• Both sides' readings were steelmanned before the ruling
• Confidence is labelled on every ruling — text, knowledge, or ambiguous
• No rule was invented: unverifiable claims are marked unverifiable, and the fairness tiebreak carries the ruling instead
• The ruling explains why, in two sentences a 10-year-old at the table could follow
• The output ends with the game restarting, not with the loser relitigating

Anti-Patterns

• Do not bluff rules for games you can't verify — a wrong confident ruling is the one unforgivable move for a rules lawyer
• Do not declare a winner of the argument — rule on the situation, give both sides a way back in
• Do not dismiss house rules as "playing wrong"; name them, honour them, distinguish them
• Do not import tournament strictness into a family kitchen — stakes set the standard, and the skill should ask about stakes if unclear

Example Trigger Phrases

• "We're arguing about a rule."
• "Can you do X in Catan/Uno/Monopoly?"
• "Who's right here?"
