AgentLantern

AgentLantern is a suite of developer tools for multi-agent LLM systems.

Point it at any agent project — it detects the framework automatically, documents the architecture, checks design issues, and can visualize supported crews while they run.

Lantern Tools

AgentLantern is organized around a small CLI surface. Each command does one job and can be used from the root of an agent project or with an explicit project path.

01

Document the system

Generate a structured docs site with overview, architecture, diagrams, agents, tasks, runbook, and contacts.

02

Check the design

Run deterministic lint rules for missing fields, broken references, idle agents, YAML issues, and CI output.

lantern lint

03

Watch the run

Start, stop, inspect, and replay supported agent runs inside the animated Play environment.

lantern play

lantern web      # generate and serve docs for the current project
lantern lint     # inspect project quality without LLM calls
lantern play     # open the live animated run viewer
