Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00108 | $0.01127 |
| Opus 5.5 | $0.00043 | $0.00451 |
| Sonnet 5.5 | $0.00022 | $0.00225 |
| Haiku 4.5 | $0.00011 | $0.00113 |
Grade A, and why
common-law-client-explainer 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mandanten-Erklärer
Zweck
Management und Business-Team bekommen klare Entscheidungspunkte statt Wörterbuchdogmatik.
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
- Jurisdiktion fixieren. Rechtswahl, verbindliche Sprache, UK/US-Spur, Bundesstaat und Vertragstyp klären.
- Begriff funktional prüfen. Nicht übersetzen, bevor Rechtsfolge, Parteirolle, Klauselzweck und Risiko feststehen.
- False Friends markieren. Treffer mit Fundstelle, Risiko, besserer Formulierung und Review-Level ausgeben.
- Ton steuern. Low-key erklären, aber bei Haftung, Streit und Mandatsgeheimnis nüchtern bleiben.
- 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:
- Who is the client — German-headquartered company, individual, or in-house counsel?
- What common law concept needs explaining — and at what depth?
- Is English the client's working language — or does a German explanation parallel work better?
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.

common-law-client-explainer is a skill published in the GitHub repository ThomasMoreAI/legal-skills-open (95 stars, last pushed 15d ago), licensed Apache-2.0. It adds 108 tokens to every session and 1,127 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings.
