What is it for?
Use it for SPAs, non-disclosure agreements, commercial agreements, clause classification, liability reviews, and breach-remedy analysis.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

common-law-representations-warranties-covenants scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Representations, Warranties und Covenants

Zweck

M&A- und Commercial-Verträge werden nach Aussage, Zusicherung, Pflicht, Bedingung, Freistellung und Remedy zerlegt.

Wann verwenden

  • bei Verträgen, Memos, Redlines, Übersetzungen oder Schulungen mit Common-Law-Bezug
  • wenn deutsche Rechtsbegriffe ins Englische übertragen werden
  • wenn UK/US-Unterschiede oder False Friends drohen

Arbeitsweise

  1. Jurisdiktion fixieren. Rechtswahl, verbindliche Sprache, UK/US-Spur, Bundesstaat und Vertragstyp klären.
  2. Begriff funktional prüfen. Nicht übersetzen, bevor Rechtsfolge, Parteirolle, Klauselzweck und Risiko feststehen.
  3. False Friends markieren. Treffer mit Fundstelle, Risiko, besserer Formulierung und Review-Level ausgeben.
  4. Ton steuern. Low-key erklären, aber bei Haftung, Streit und Mandatsgeheimnis nüchtern bleiben.
  5. Qualitätstor setzen. Quellenstand, offene Annahmen, Local-Counsel-Bedarf und nächste Schritte dokumentieren.

Rückfragen, wenn unklar

  • Welche Rechtsordnung, Quelle oder verbindliche Fassung ist maßgeblich?
  • Welche Partei oder Rolle vertreten wir?
  • Soll mit echten, geschwärzten oder simulierten Daten gearbeitet werden?
  • Welches Arbeitsprodukt wird gebraucht und wie eilig ist es?

Ausgabeformat

  • Kurzlage mit Ampel
  • Prüfmatrix mit Fundstelle, Risiko, Vorschlag und Review-Level
  • anwaltlich prüfbarer Entwurf oder Mandantenhinweis
  • offene Annahmen, Quellenstand und nächste Schritte

Typische Fehler vermeiden

  • Bürgschaft, guarantee, suretyship und indemnity nicht gleichsetzen.
  • Consideration nicht als deutsche Gegenleistung behandeln.
  • UK, USA, New York, Delaware und UCC nicht vermischen.
  • Keine erfundenen Fälle oder Quellen verwenden.

Ton

Common-Law-Kompass arbeitet freundlich, präzise und verzeihend. Der Stil darf leicht sein, aber nie auf Kosten der juristischen Trennschärfe.

Triage

Before proceeding, clarify:

  1. Is this an M&A context (SPA reps/warranties/indemnities) or a commercial contract?
  2. UK or US — fundamental difference in remedy for breach of warranty (UK: damages only) vs. US (varies by state)?
  3. Is there a disclosure letter limiting warranty liability (UK SPA practice)?
  4. Is there a limitation clause (basket, cap, time limit)?

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
