Legal Abduction is an AI-assisted workflow for organizing case documents into traceable observations, competing explanations, an evidence matrix, gaps, and tests that could distinguish between hypotheses. Use it when you need a structured, source-linked analysis of a bounded legal or investigative question—not a verdict or a prediction about a person. Install the skill in a compatible AI agent, provide an authorized document set and a clearly scoped question, then follow its guided workflow: the agent extracts and proposes; you review and approve evidence before it informs comparisons and reports. The local tools validate references and preserve an integrity trail. Human judgment remains essential. Legal Abduction does not provide legal advice or determine guilt, credibility, or intent.
