Legal Brief

Q: How do I know the Legal Brief output is good?

The skill verifies itself against its own quality checks: Issue is stated as a specific legal question (not a general topic); Brief answer appears before the analysis (conclusion upfront); Disputed facts are explicitly flagged; Areas of legal uncertainty are noted (not hidden in confident language).

What to give it

▸Brief type — legal memo / case summary / argument outline / position paper / letter before action

▸Legal issue or question

▸Jurisdiction — England & Wales / US / EU / Other

▸Relevant facts

▸Relevant law or cases — if known — otherwise flagged as [RESEARCH NEEDED]

▸Audience — internal memo / court submission / client letter

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Issue is stated as a specific legal question (not a general topic)

✓Brief answer appears before the analysis (conclusion upfront)

✓Disputed facts are explicitly flagged

✓Areas of legal uncertainty are noted (not hidden in confident language)

✓Caveats section lists what would change the analysis

✓Disclaimer is included

⚠️ What it refuses to do

Do not present uncertain legal positions with confident language — areas of legal ambiguity must be flagged explicitly, not smoothed over

Do not omit the disclaimer — every legal brief output must include the professional review caveat before the user treats it as advice

Do not structure the brief chronologically — IRAC format (Issue, Rule, Application, Conclusion) must be used regardless of how the user framed the request

Do not cite cases or statutes from memory without flagging them as [REQUIRES VERIFICATION] — hallucinated citations are worse than no citations

Do not conflate jurisdiction — legal positions in England & Wales, US, and EU can differ materially; always confirm jurisdiction before stating the rule
