Legal: Litigation Chronology Assembly with Claude Code: Result JSON Schema
A production playbook for litigation chronology assembly in legal operations using Claude Code: result json schema, run-scoped inputs, logs, typed results, and artifacts.
Audience: Litigation teams preparing case timelines
The problem
Litigation teams preparing case timelines need litigation chronology assembly to run repeatedly against pleadings, discovery exports, emails, deposition notes, and evidence folders. In legal operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Define the outer result contract once, let the litigation chronology assembly skill own body.data, and reject terminal output that does not match the expected schema.
Tradeoffs and failure modes
Schema enforcement adds upfront design work, but removes prompt parsing from the product surface. For litigation chronology assembly, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
