lingtai — Go monorepo (TUI + portal)Location: github.com/Lingtai-AI/lingtai
Two binary targets in one repo:
| Binary | Source | Build output | Role |
|---|---|---|---|
lingtai-tui | tui/ | tui/bin/lingtai-tui | Terminal UI — Bubble Tea v2 + lipgloss v2. Agent launcher, monitor, mail viewer, preset editor, first-run wizard. |
lingtai-portal | portal/ | portal/bin/lingtai-portal | Web portal — Go HTTP server with embedded React 19 frontend. Network visualization, mail/replay UI, topology recorder. |
Key packages in tui/internal/:
| Package | Role |
|---|---|
tui/ | Bubble Tea models for every screen (~22k LOC) |
preset/ | Atomic {llm, capabilities} bundle layer |
migrate/ | Versioned, append-only migration system for .lingtai/ state |
globalmigrate/ | Per-machine migrations under ~/.lingtai-tui/ |
fs/ | Filesystem read accessors into agent working directories |
config/ | Global TUI config under ~/.lingtai-tui/ |
process/ | Subprocess launcher for python -m lingtai run <dir> |
i18n/ | en/zh/wen JSON tables (three locales always) |
Key packages in portal/internal/:
| Package | Role |
|---|---|
api/ | HTTP server, handlers, replay endpoint |
fs/ | Filesystem accessors (same shape as TUI's, portal-tailored) |
migrate/ | Versioned migrations (shares meta.json version space with TUI) |
web/ | React 19 + TypeScript + Vite frontend (embedded into Go binary) |
lingtai-kernel — Python kernelLocation: github.com/Lingtai-AI/lingtai-kernel
Published as the lingtai package on PyPI. Contains:
src/lingtai/kernel/ — the minimal agent runtime (turn loop, lifecycle, tool dispatch, mailbox, soul/molt orchestration)src/lingtai/ — the batteries-included wrapper (MCP, FileIO, Vision, Search, CLI)The wrapper depends on the kernel one-directionally. The kernel never imports from the wrapper.

(.lingtai/<agent>/)
The TUI and portal never open a socket or RPC channel to a running agent. All
communication is through files — agent manifests, heartbeats, signal files,
mailbox folders, .notification/. This is a deliberate design choice: any new
cross-process communication should follow the same pattern (write a file, let the
other side poll).
TUI → kernel: The TUI launches agents via python -m lingtai run <dir> as a subprocess (tui/internal/process/launcher.go). After spawn, the TUI never talks to the agent process directly — only via the agent's working directory.
TUI → filesystem (read): .agent.json, .agent.heartbeat, mailbox/, logs/token_ledger.jsonl, history/chat_history.jsonl, system/*.md, .notification/*.json.
TUI → filesystem (write): Signal files only: .sleep, .suspend, .interrupt, .clear, .prompt, .refresh, .inquiry, .forget. Plus init.json via explicit user actions.
TUI ↔ Homebrew tap: Pushing a release tag runs the root release workflow, which updates Lingtai-AI/homebrew-lingtai/lingtai-tui.rb.
Portal ↔ TUI: The TUI discovers an installed lingtai-portal to launch on /viz; otherwise the binaries are independent.
| Repo | Relationship to lingtai |
|---|---|
lingtai-kernel | Runtime dependency only (the Python agent the TUI launches). Not a build-time dependency. |
lingtai-skill | Canonical mailbox-protocol SKILL.md. Vendored into plugin repos. |
lingtai-claude-code | Claude Code plugin (SessionStart hook, marketplace manifest). |
codex-plugin | OpenAI Codex CLI plugin. |
lingtai-imap / lingtai-telegram / lingtai-feishu / lingtai-wechat | MCP server addons. Each is a separate PyPI package. |
Lingtai-AI/homebrew-lingtai | Homebrew tap for lingtai-tui. |

Official-source-led manual for the TUI `claude` template.
Base URL / API-compat / provider / model / capability declaration shape versus credentials and live probes; includes proven Codex OAuth quota inspection with exact agent query routing and dated official-vs-measured context-window evidence.
Thin dual-axis router for preset questions: which of the 12 TUI-shipped built-in preset templates (provider axis), and which cross-cutting preset lifecycle mechanic (operation axis) — saving, checking availability, activating/refreshing, endpoint/capability facts, or troubleshooting. Read a child only when it is relevant; this does not describe arbitrary saved presets.
Anything you need to know about LingTai TUI. Read this first for the stable mental model, major-feature map, interface and slash-command help, or the correct source/manual route for a TUI question. It stays thin: exact command prose lives in the localized help assets, precise Go structure lives in `lingtai-tui-anatomy` plus the repository ANATOMY graph, and independent domains such as presets, Portal, tutorials, updates, and addons keep their own top-level skills.
Nested tutorial-guide reference for lessons 10–12: TUI commands, lifecycle exercises, addons, external connections, and graduation.
The 12-lesson tutorial curriculum for teaching a human how Lingtai works. Router for orientation, agent runtime, communication, memory/molt, capabilities, operations, addons, and graduation. Invoke this skill when the human is ready to begin or continue the tutorial.
