thuyran / legal-skills-chinese

Trigger this skill when the following situations arise in legal reasoning: (1) the text of a legal provision is ambiguous and open to multiple interpretations; (2) disputes arise when applying a provision to specific case facts; (3) it is necessary to argue that a certain provision should or should not apply to a particular situation; (4) the two parties disagree on the interpretation of the same provision; (5) provisions appear to conflict and need to be reconciled through interpretation; (6) novel case facts cannot be directly mapped to the text of an existing provision; (7) it is necessary to analyze or challenge the application of law in a judicial document. The core of this skill is to use legal interpretation methods such as literal, systematic, and teleological interpretation to conduct rigorous interpretive argumentation on key provisions, arrive at reasonable and defensible legal meanings, and present the interpretation process and conclusions in a standardized manner.

structured-element-extraction
structured-element-extraction
thuyran / legal-skills-chinese

When an AI Agent needs to systematically analyze a legal question, case facts, a legal provision or a legal relationship, it must first break it down into a structured list of elements. This skill triggers in the following scenarios: - A case fact description is received and all legal elements must be extracted before analysis - A legal relationship must be judged as established or not (e.g. contract formation, tort constitution, crime constitution) - Two or more legal facts/provisions must be compared for similarities and differences - It serves as a pre-quality gate before downstream tasks such as legal reasoning, legal application and legal advice - The user explicitly requests to "list the elements", "analyze item by item", or "check for omissions". The core goal of this skill is to ensure element extraction is complete and without omissions, forming a traceable, verifiable structured list, and only then allowing entry into the next stage of reasoning. It is the "quality gate" in the legal analysis chain.

conflict-resolution
conflict-resolution
thuyran / legal-skills-chinese

Trigger this skill when an AI agent encounters the following situations in legal reasoning: (1) multiple legal provisions apply to the same facts (competing statutory provisions); (2) evidence contradicts or is inconsistent with other evidence (evidence conflicts); (3) a case has multiple points of dispute requiring a determination of hearing or analysis order (prioritizing disputed issues); (4) different legal sources (statutes, regulations, judicial interpretations, local regulations, etc.) make different provisions on the same question (conflicts of legal sources); (5) there is tension between a party's claims and the application of law that needs to be reconciled. This skill is a core hub capability of legal reasoning, and almost all complex legal analysis involves some form of conflict resolution.

Other92
D
dispute-and-performance-risk
dispute-and-performance-risk
thuyran / legal-skills-chinese

This skill triggers when a user submits contract text, a transaction arrangement, a business agreement or a description of a legal relationship and needs to assess possible legal disputes or breach-of-contract risks. Typical trigger scenarios include but are not limited to: - The user asks for a contract review and identification of potential risks - The user asks whether a transaction arrangement has any obstacles to performance - The user describes difficulties in contract performance and needs to determine whether they constitute a breach - The user asks for a risk rating of contract clauses - The user provides an agreement between two or more parties and asks to identify possible points of dispute - The user describes a performance deviation that has already occurred and needs to assess the legal consequences - Forward-looking risk identification is needed in scenarios such as contract review, due diligence and transaction negotiation This skill focuses on the two core questions of "whether legal disputes will arise" and "whether breach-of-contract risks exist", and outputs a structured risk list with recommended responses.

Trigger this skill when specific legal consequences need to be derived from confirmed legal facts, identified legal relationships, and matched legal norms (including but not limited to the type and scope of civil liability, calculation of damages, determination of criminal sentences, type and extent of administrative penalties, validity status of contracts, etc.). Typical trigger scenarios include: - The user asks "how much compensation can I get" or "what liability does the other party bear" - The user asks "how many years will this behavior get" or "how much is the fine" - The need to derive specific legal effects from the satisfaction of legal constituent elements - The need to calculate quantified results such as specific compensation amounts, sentence ranges, or penalty amounts - The need to reach a final legal consequence after comprehensively considering adjustment factors such as aggravation, mitigation, or exemption.
