Lean 4 Document-to-Requirements
Extract formal specification requirements from informal documents (papers, reports, specs) and map them to Lean 4 theorem statements.
Routing
- USE FOR: Extract formal requirements from academic papers, technical reports, and design documents. Use when converting informal mathematical claims into Lean 4 theorem specifications. Covers claim extraction from LaTeX sources, equation identification, proposition mapping, hypothesis inference, and requirement traceability from document to formal specification.
- DO NOT USE FOR: paper update post-Lean (use @lean-doc-improvement); specification design (use @lean-specification); blueprint generation (use @lean-blueprint).
- TRIGGERS: doc requirements, requirement extraction, informal-to-Lean, claim extraction, paper-to-spec.
Workflow
- Read the source document; identify each informal mathematical claim, its scope, and implicit assumptions.
- Pick the requirement template from the body matching the claim class (definition, theorem, lemma, tactic-rule).
- Produce a draft Lean specification (signature only, no proof) with traceability back to the source.
- Hand off: to
@lean-specificationfor the formal spec design, to@lean-prooffor the proof, to@lean-zettelkasten.
Recovery & STOP
- STOP if the document is being updated FROM Lean — delegate to
@lean-doc-improvement. - STOP if claims are too vague to formalise — request HITL clarification.
- STOP if a project-level blueprint is needed — delegate to
@lean-blueprint.
