lean4-memories

Persistent memory for Lean 4 proofs stores successful patterns, failed approaches, and project conventions across sessions using MCP memory server integration. When you encounter similar theorem goals weeks later, the Skill retrieves proven tactics and strategies, eliminating duplicate exploration and accelerating proof discovery.

Yes. The Skill scopes memory by project path, skill context, and entity types—ProofPattern, FailedApproach, ProjectConvention, UserPreference, and TheoremDependency—with metadata including goals, tactics, lemmas, difficulty, and file contexts for precise retrieval and project-specific expertise.

Accumulate domain knowledge and coding conventions specific to your formalization project by persisting successful proof strategies and failed attempts. Team members benefit from shared memory of what works, reducing onboarding time and ensuring consistent proof approaches across collaborative projects.

Storing proof patterns, tactics, and conventions creates a queryable knowledge base that enforces consistent approaches and lemma usage. New team members and future sessions apply proven strategies rather than reinventing solutions, improving code quality and reducing proof complexity.

Yes. The Skill is designed for multi-session Lean 4 formalizations with recurring proof patterns and complex proofs. It remembers which tactics and lemmas succeeded on similar goals, enabling rapid pattern matching and reducing the cognitive load of managing proof strategy across lengthy formalization efforts.
