Amendment History (合同修订追溯)

What it does

This skill ingests a base agreement plus one or more amendment documents, orders them chronologically, and produces either a timeline-style summary of all changes or a clause-level trace showing exact before/after language. Outputs include per-revision summaries, a current-state clause table, and observation flags for conflicts or inconsistencies. The skill preserves confidentiality guidance and frames outputs for legal review.

When to use it

Use when a user asks 'what changed in this contract', 'show revision history', or requests the 'current version of [provision]'. Useful for contract review prep, diligence, and legal ops when multiple versions exist.

What's included

• Scripts: none packaged, but the SKILL.md provides detailed workflow rules for ordering, indexing and reporting changes
• References: detailed output templates (timeline, clause-tracking) and mode detection (summary vs provision-tracking) in the skill body
• Instructions: load files, detect mode, build index, extract § references and produce markdown outputs with a decision-tree for next steps.

Compatible agents

Best used with agents that can parse PDFs/text and produce structured markdown outputs (Claude/Gemini/Codex-capable agents). Agents should support file upload handling and maintain confidentiality context.
