Introduction

LNAI is a CLI tool that syncs a unified .ai/ configuration to native formats for AI coding tools.

The Problem

Modern developers use multiple AI coding assistants:

Claude Code
Codex
Gemini CLI
OpenCode
Cursor
GitHub Copilot
Windsurf
And more…

Each tool has its own configuration format, leading to:

Duplication: Same rules defined multiple times
Drift: Configurations get out of sync
Maintenance burden: Updates need to be made in multiple places

The Solution

LNAI provides a single source of truth in the .ai/ directory that exports to native formats:

.ai/
├── config.json
├── settings.json
├── AGENTS.md
├── rules/*.md
├── skills/<name>/SKILL.md
├── .claude/   (overrides)
├── .codex/    (overrides)
├── .cursor/   (overrides)
├── .gemini/   (overrides)
├── .opencode/ (overrides)
├── .copilot/  (overrides)
└── .windsurf/ (overrides)

Outputs:
- AGENTS.md (root, shared by most tools)
- .agents/ (skills/, shared by Codex + OpenCode)
- .claude/ (CLAUDE.md, settings.json, rules/, skills/)
- .codex/ (config.toml)
- .cursor/ (rules/*.mdc, mcp.json, cli.json, skills/)
- .gemini/ (settings.json, skills/) + <dir>/GEMINI.md
- .opencode/ (rules/) + opencode.json
- .github/ (instructions/, skills/) + .vscode/mcp.json
- .windsurf/ (rules/, skills/)
