## Overview / 概览

This fork contains both **upstream MIT-licensed code** (from the original opencode project by sst / anomalyco) and **newly-authored modules** (by the fork author) licensed under the GNU Affero General Public License v3.

本 fork 同时包含两类代码：**上游 MIT 许可代码**（来自 sst / anomalyco 的 opencode 项目）与 **作者自研模块**（采用 GNU AGPL v3 许可）。

## Upstream Attribution / 上游归属

- **Project**: opencode

- **Upstream license file**: [`LICENSE`](./LICENSE) (preserved verbatim)

This fork retains the upstream copyright notice and permission notice in all copies and substantial portions of upstream-derived code, in compliance with the MIT license.

> **Relationship disclaimer**: This fork is an independent, community enhancement. It is **not affiliated with, endorsed by, or officially supported** by the OpenCode team (sst / anomalyco). The author of this fork makes no claim of being an official opencode release.

## Modules Authored by This Fork / 本 fork 自研模块

The following modules were authored (or substantially rewritten) by the fork author and are licensed under the **GNU Affero General Public License v3** (`AGPL-3.0`). The full text of the license is at [`packages/opencode/src/dag/LICENSE`](./packages/opencode/src/dag/LICENSE).

| `packages/opencode/src/tool/dagworker.ts` | `dagworker` builtin tool for LLM-driven workflow create/start/replan/list/cancel |
| `packages/opencode/src/tool/dagworker.txt` | Tool description template (text) |
| `packages/opencode/src/tool/node_complete.ts` | `node_complete` builtin tool for sub-agent signal back |
| `packages/opencode/src/tool/node_complete.txt` | Tool description template (text) |
| `packages/opencode/src/command/template/dag-ctl.txt` | `/dag-ctl` slash command template (text) |
| `packages/opencode/src/session/prompt/dag.txt` | LLM system prompt DAG injection (text) |

| `docs/readmes/upstream-features.md` | Upstream-only features retention doc (markdown) |
| This `NOTICE` file | License boundary and attribution doc (text) |

| `README_EN.md` (this repo root) | Fork-level README (English) |

These files carry an `SPDX-License-Identifier: AGPL-3.0-or-later` header to make the licensing machine-readable.

## Upstream-Modified Files / 上游修改过的文件

A small set of upstream MIT files have been patched to add integration hooks for the DAG engine. These files **remain under the upstream MIT license**; the tiny amount of hook glue code added to them is released by this fork's author under the same MIT license for consistency.

少量上游 MIT 文件被修改以接入 DAG 引擎的集成钩子。这些文件**仍由上游 MIT 许可覆盖**；其中加入的极少量胶水代码由本 fork 作者以 MIT 许可一并释出，保持一致性。

| File / 文件 | Modification / 修改点 |
|-------------|------------------------|
| `packages/opencode/src/session/system.ts` | Added `dag()` entry to the system-prompt builder |
| `packages/opencode/src/session/prompt.ts` | Called `sys.dag(sessionID)` in the system prompt assembly chain |
| `packages/opencode/src/tool/registry.ts` | Registered `dagworker` + `node_complete` as builtin tools |
| `packages/opencode/src/command/index.ts` | Registered `dag-ctl` slash command ID and template wiring |

## How to Comply / 如何合规

### If you use only upstream parts of this fork (no DAG modules)

Follow the upstream MIT license — retain `LICENSE` and copyright notices. No copyleft obligations.

### If you use any of the AGPL-3.0 modules listed above

Per AGPL-3.0 §5 and §13:
- You must release the **complete Corresponding Source** of any modifications or derivative works that include AGPL-3.0 modules.
- You must preserve author attribution and license notices on every AGPL-3.0 file.
- If you run a modified version on a public network server, you must offer users the source of that modified version (AGPL §13's distinctive clause beyond GPL).

### If you redistribute a binary build

- Include a copy of both `LICENSE` (MIT) and `packages/opencode/src/dag/LICENSE` (AGPL-3.0) in the distribution.
- Preserve this `NOTICE` file.
- For AGPL modules, provide Corresponding Source alongside (or via written offer per AGPL-3.0 §6).
