SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Collaborative theorem proving often stalls as humans juggle goals, decompositions, and verification steps. Lean-collab orchestrates multi-agent proof sessions, managing skeleton design, verification, and final proof composition without manual micromanagement.

Core Features & Use Cases

Orchestrates parallel Lean proof sessions via a CLI workflow (lc) to run decomposers and provers concurrently.
Maintains a structured workflow from root theorem initialization through status checks, decompositions, backtracking, verification, and final composition.
Supports real-time, Ensue-coordinated status updates and goal management for collaborative formalization tasks.

Quick Start

Initialize the LC session with a root theorem and hypotheses, then let the orchestrator run until the proof is complete.

FAQPage Schema

How do I coordinate parallel Lean proofs across multiple agents?▼

Parallel Lean proofs are coordinated by orchestrating multi-agent sessions via the lc CLI, which runs decomposers and provers concurrently while tracking real-time status to produce a verified proof.

What is multi-agent theorem proving and when do I need it for Lean projects?▼

Multi-agent theorem proving decomposes a root theorem into parallel sub-goals handled by concurrent provers, needed when formalization tasks outpace single-agent verification or require structured skeleton design and backtracking.

How do I start a collaborative Lean proof session using a CLI workflow?▼

Initialize the session by declaring a root theorem and hypotheses through the lc CLI, then let the orchestrator manage decomposition, verification, and final proof composition until completion.

Can I manage Lean proof goals and backtracking automatically during multi-agent sessions?▼

Automated goal management and backtracking are supported natively, allowing the orchestrator to track sub-goal status, apply decompositions, and revert failed proof branches without manual intervention.

Does lean-collab work without external dependencies for theorem verification?▼

Lean-collab operates with zero external dependencies, relying solely on the lc CLI and Ensue-coordinated execution to manage the full proof lifecycle from initialization through final composition.

Why does my collaborative Lean proof workflow stall during goal decomposition?▼

Proof workflows stall when decomposition, verification, and composition steps lack coordinated status tracking; lean-collab resolves this by orchestrating parallel agent tasks with real-time Ensue updates and automated goal management.
