atomcode AGENTS.md

A project instruction document describing the current architecture, development boundaries, and rules for an AtomCode coding agent. It is written in Chinese and covers components such as the command-line tool, terminal interface, background service, and runtime.

In plain words
What is it for?
Use it when designing or modifying the listed Rust crates, runtime and session code, command and event handling, protocols, saved data formats, approvals, security boundaries, or cross-crate dependencies.
Why use it?
It gives developers a shared reference for changing sensitive parts of the system without relying on outdated migration notes or accidentally creating duplicate runtime lifecycles.

Token cost

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.

Security

Grade A, and why

atomcode AGENTS.md 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 2d 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.

项目全局开发约束

适用范围与使用方式

本文件记录当前架构边界和长期开发约束,不再承担历史迁移进度报告的职责。历史方案、旧基线和已完成的 bridge 退役过程应留在 docs/,不得继续作为当前实现前提。

涉及以下范围时,设计或修改前必须先核对当前代码、调用方和近期 Git 历史:

  • crates/atomcode-kernel/
  • crates/atomcode-capabilities/
  • crates/atomcode-coding/ 的 runtime、provider、session、controller;
  • CLI、TUI、daemon、ACP、clix 的 runtime、session、command/event 接入;
  • daemon 中保留的历史 core JSON 单向 importer 与兼容 DTO;
  • 公共协议、持久化格式、审批、安全边界或跨 crate 依赖方向。

本文件描述的是约束,不是永远正确的现状快照。若约束中的事实与当前代码冲突,以当前代码为准;先说明差异,再修正文档或实现,不得按旧路径盲目补代码。

当前架构事实

当前 coding agent 的目标调用链是:

CLI / TUI / daemon / background / ACP / clix code
                    │
                    ▼
       CodingRuntimeHandle / DriverCommand
                    │
                    ▼
               CodingRuntime

          atomcode-kernel Agent
  • CodingRuntime 是 coding agent 的运行时所有者;driver 不应重新持有或重建第二套 live agent 生命周期。
  • kernel AgentCommand/AgentEvent 是运行时执行边界。coding 产品 driver 应使用 CodingRuntime;其他业务 driver 可以驱动其 L2 已装配的 kernel agent,但不得另建第二生命周期 owner,也不得把 provider、session、cd、goal、loop 等 coding 生命周期重新塞进 kernel 命令。
  • core legacy AgentClient/AgentCommand/AgentEvent、v1 engine 和 atomcode-bridge 已退役。不得重新引入 bridge、双 endpoint、v1/v2 选择开关或 core driver fallback。
  • atomcode-kernelatomcode-capabilitiesatomcode-coding 的生产依赖必须保持 core-free;尤其禁止 capabilities 反向依赖 core、L2 或前端。
  • native SessionManager/SessionMeta/SessionSnapshot/PresentationFile 是唯一 session 持久化模型;core session 模块与持久化 API 已退役。历史 core JSON 只允许由 daemon 私有 DTO 单向导入,禁止恢复 legacy writer、core 磁盘投影或双向持久化转换。
  • atomcode-core crate 已从 workspace 删除;生产代码不得重新依赖或重建同名兼容层。历史 core JSON 只由 daemon 私有 DTO 单向导入。
  • daemon/TUI 的 live/provider/UI 投影必须直接使用 kernel/coding 中立类型;持久化读取必须先得到严格 native 聚合。不得借转换层恢复旧 engine 命令、第二 runtime owner、core session 磁盘模型或静默 fallback。

架构方向

  • 目标是单一状态所有权、清晰依赖方向和可验证兼容性;已经删除的 core 不得以 facade、兼容 crate 或复制状态所有者的方式回流。
  • driver 负责输入、展示、传输和明确的本地操作;coding runtime 负责业务生命周期;kernel 只负责中立 agent 循环;capabilities 提供可复用能力实现。
  • 不需要运行中 conversation/provider/session 的本地查询或副作用,应留在 driver/local service。需要操作运行中状态的行为必须通过 runtime 定义清楚的命令、事件和终态。
  • 新能力优先放入职责正确的现有层。不得把业务语义下沉到 kernel,也不得为了去 core 新建一个无边界的“杂物 crate”。
  • 不预设必须先创建 atomcode-protocol。只有出现稳定跨进程 schema、非 Rust codegen 或独立版本契约的真实需求时,才拆纯协议叶子;否则复用现有 kernel/coding 中立类型。
  • 不预设创建大而全的 atomcode-foundation。config、auth、plugin、session、transport、process utilities 应按内聚职责复用现有 crate 或独立拆分,避免产生新的 core。
  • 版本号、发布配置和版本策略不属于默认架构收口范围;除非任务明确要求,不得顺带修改。
  • 问题修复必须检查同一状态所有权、协议边界和受影响 driver,优先修复共同根因;不得只修点名入口而让其他入口继续使用错误路径。

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.
