Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.01816 |
| Opus 5 | $0.00022 | $0.00908 |
| Sonnet 5 | $0.00009 | $0.00363 |
| Haiku 4.5 | $0.00004 | $0.00182 |
Grade A, and why
dev-guide-architecture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architecture
Nested lingtai-dev-guide reference. Read this after the top-level router sends you here. This document maps the LingTai project: what the pieces are, how they connect, and where state lives.
The two repos
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/ |
Retained historical/test migration registry (m001–m039); production startup no longer runs it or advances .lingtai/meta.json |
globalmigrate/ |
Live per-machine migrations under ~/.lingtai-tui/ (run by the TUI at startup) |
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/ |
Retained historical migration registry/tests (m001–m039); Portal production does not run it |
web/ |
React 19 + TypeScript + Vite frontend (embedded into Go binary) |
lingtai-kernel — Python kernel
Location: 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)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 144 lines · 44 tokens per session scan A d75c0185270f
dev-guide-architecture is a skill published in the GitHub repository Lingtai-AI/lingtai (670 stars, last pushed yesterday), licensed Apache-2.0. It adds 44 tokens to every session and 1,816 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
