Coding Agent (bash-first)

编码Agent（优先使用bash）

Use bash (with optional background mode) for all coding agent work. Simple and effective.

所有编码Agent相关工作都使用bash（可选择后台模式），简单高效。

⚠️ PTY Mode: Codex/Pi/OpenCode yes, Claude Code no

⚠️ PTY模式：Codex/Pi/OpenCode需要开启，Claude Code不需要开启

For Codex, Pi, and OpenCode, PTY is still required (interactive terminal apps):

bash

undefined

对于Codex、Pi和OpenCode，仍需要PTY（交互式终端应用）：

bash

undefined

✅ Correct for Codex/Pi/OpenCode

✅ Codex/Pi/OpenCode的正确用法

bash pty:true command:"codex exec 'Your prompt'"


For **Claude Code** (`claude` CLI), use `--print --permission-mode bypassPermissions` instead.
`--dangerously-skip-permissions` with PTY can exit after the confirmation dialog.
`--print` mode keeps full tool access and avoids interactive confirmation:

```bash

bash pty:true command:"codex exec 'Your prompt'"


对于**Claude Code**（`claude` CLI），请改用`--print --permission-mode bypassPermissions`参数。
搭配PTY使用`--dangerously-skip-permissions`会在确认对话框后退出。
`--print`模式保留完整工具权限，且无需交互式确认：

```bash

✅ Correct for Claude Code (no PTY needed)

✅ Claude Code的正确用法（无需PTY）

cd /path/to/project && claude --permission-mode bypassPermissions --print 'Your task'

For background execution: use background:true on the exec tool

如需后台执行：在exec工具上添加background:true参数

❌ Wrong for Claude Code

❌ Claude Code的错误用法

bash pty:true command:"claude --dangerously-skip-permissions 'task'"

undefined

bash pty:true command:"claude --dangerously-skip-permissions 'task'"

Quick Start: One-Shot Tasks

快速入门：一次性任务

For quick prompts/chats, create a temp git repo and run:

bash

undefined

对于快速提问/对话，创建临时git仓库后运行：

bash

undefined

Quick chat (Codex needs a git repo!)

快速对话（Codex需要git仓库！）

SCRATCH=$(mktemp -d) && cd $SCRATCH && git init && codex exec "Your prompt here"

Or in a real project - with PTY!

或者在真实项目中使用 - 记得开启PTY！

bash pty:true workdir:~/Projects/myproject command:"codex exec 'Add error handling to the API calls'"


**Why git init?** Codex refuses to run outside a trusted git directory. Creating a temp repo solves this for scratch work.

---

bash pty:true workdir:~/Projects/myproject command:"codex exec 'Add error handling to the API calls'"


**为什么要执行git init？** Codex拒绝在受信任的git目录之外运行，创建临时仓库可以解决临时工作的运行问题。

---

The Pattern: workdir + background + pty

推荐模式：workdir + background + pty

For longer tasks, use background mode with PTY:

bash

undefined

对于长时间运行的任务，使用带PTY的后台模式：

bash

undefined

Start agent in target directory (with PTY!)

在目标目录启动Agent（开启PTY！）

bash pty:true workdir:~/project background:true command:"codex exec --full-auto 'Build a snake game'"

Returns sessionId for tracking

返回sessionId用于跟踪

Monitor progress

监控进度

process action:log sessionId:XXX

Check if done

检查是否完成

process action:poll sessionId:XXX

Send input (if agent asks a question)

发送输入（如果Agent询问问题）

process action:write sessionId:XXX data:"y"

Submit with Enter (like typing "yes" and pressing Enter)

输入后按回车提交（类似输入"yes"后按回车键）

process action:submit sessionId:XXX data:"yes"

Kill if needed

必要时终止任务

process action:kill sessionId:XXX


**Why workdir matters:** Agent wakes up in a focused directory, doesn't wander off reading unrelated files (like your soul.md 😅).

---

process action:kill sessionId:XXX


**为什么workdir很重要：** Agent会在指定目录下工作，不会乱跑读取无关文件（比如你的soul.md 😅）。

Codex CLI

Model:

gpt-5.2-codex

is the default (set in ~/.codex/config.toml)

模型： 默认使用

gpt-5.2-codex

（可在~/.codex/config.toml中设置）

Flags

可用参数

Flag	Effect
`exec "prompt"`	One-shot execution, exits when done
`--full-auto`	Sandboxed but auto-approves in workspace
`--yolo`	NO sandbox, NO approvals (fastest, most dangerous)

参数名	作用
`exec "prompt"`	一次性执行，完成后自动退出
`--full-auto`	沙箱环境，但在工作区内自动审批操作
`--yolo`	无沙箱、无审批（速度最快，风险最高）

Building/Creating

构建/创建功能

Reviewing PRs

审核PR

⚠️ CRITICAL: Never review PRs in OpenClaw's own project folder! Clone to temp folder or use git worktree.

bash

undefined

⚠️ 关键提醒：绝对不要在OpenClaw自己的项目文件夹中审核PR！ 请克隆到临时文件夹或使用git worktree。

bash

undefined

Clone to temp for safe review

克隆到临时目录安全审核

REVIEW_DIR=$(mktemp -d) git clone https://github.com/user/repo.git $REVIEW_DIR cd $REVIEW_DIR && gh pr checkout 130 bash pty:true workdir:$REVIEW_DIR command:"codex review --base origin/main"

Clean up after: trash $REVIEW_DIR

完成后清理：trash $REVIEW_DIR

Or use git worktree (keeps main intact)

或者使用git worktree（不影响主分支）

git worktree add /tmp/pr-130-review pr-130-branch bash pty:true workdir:/tmp/pr-130-review command:"codex review --base main"

undefined

git worktree add /tmp/pr-130-review pr-130-branch bash pty:true workdir:/tmp/pr-130-review command:"codex review --base main"

Parallel Issue Fixing with git worktrees

使用git worktrees并行修复问题

For fixing multiple issues in parallel, use git worktrees:

bash

undefined

如需并行修复多个问题，使用git worktrees：

bash

undefined

1. Create worktrees for each issue

1. 为每个问题创建worktree

git worktree add -b fix/issue-78 /tmp/issue-78 main git worktree add -b fix/issue-99 /tmp/issue-99 main

2. Launch Codex in each (background + PTY!)

2. 为每个worktree启动Codex（后台运行+开启PTY！）

bash pty:true workdir:/tmp/issue-78 background:true command:"pnpm install && codex --yolo 'Fix issue #78: <description>. Commit and push.'" bash pty:true workdir:/tmp/issue-99 background:true command:"pnpm install && codex --yolo 'Fix issue #99 from the approved ticket summary. Implement only the in-scope edits and commit after review.'"

3. Monitor progress

3. 监控进度

process action:list process action:log sessionId:XXX

4. Create PRs after fixes

⚠️ Rules

⚠️ 规则

Use the right execution mode per agent:
- Codex/Pi/OpenCode:
```
pty:true
```
- Claude Code:
```
--print --permission-mode bypassPermissions
```
  (no PTY required)
Respect tool choice - if user asks for Codex, use Codex.
- Orchestrator mode: do NOT hand-code patches yourself.
- If an agent fails/hangs, respawn it or ask the user for direction, but don't silently take over.
Be patient - don't kill sessions because they're "slow"
Monitor with process:log - check progress without interfering
--full-auto for building - auto-approves changes
vanilla for reviewing - no special flags needed
Parallel is OK - run many Codex processes at once for batch work
NEVER start Codex in ~/.openclaw/ - it'll read your soul docs and get weird ideas about the org chart!
NEVER checkout branches in ~/Projects/openclaw/ - that's the LIVE OpenClaw instance!

根据Agent类型选择正确的执行模式：
- Codex/Pi/OpenCode：开启
```
pty:true
```
- Claude Code：使用
```
--print --permission-mode bypassPermissions
```
  （无需PTY）
尊重工具选择 - 如果用户要求使用Codex，就使用Codex。
- 编排模式：不要自己手动编写补丁。
- 如果Agent运行失败/挂起，可以重启它或询问用户方向，不要默默接管任务。
保持耐心 - 不要因为会话运行“慢”就杀死它
使用process:log监控 - 查看进度而不干扰运行
构建任务使用--full-auto - 自动审批变更
审核任务使用默认配置 - 无需特殊参数
支持并行运行 - 可以同时运行多个Codex进程处理批量任务
绝对不要在~/.openclaw/目录下启动Codex - 它会读取你的私密文档，对组织架构产生奇怪的认知！
绝对不要在~/Projects/openclaw/目录下切换分支 - 这是运行中的OpenClaw实例！

Progress Updates (Critical)

进度更新（至关重要）

When you spawn coding agents in the background, keep the user in the loop.

Send 1 short message when you start (what's running + where).
Then only update again when something changes:
- a milestone completes (build finished, tests passed)
- the agent asks a question / needs input
- you hit an error or need user action
- the agent finishes (include what changed + where)
If you kill a session, immediately say you killed it and why.

This prevents the user from seeing only "Agent failed before reply" and having no idea what happened.

当你在后台启动编码Agent时，要及时同步用户进度。

启动时发送1条短消息，说明运行的任务和所在目录。
仅在发生变化时再次更新：
- 完成一个里程碑（构建完成、测试通过）
- Agent询问问题/需要输入
- 遇到错误或需要用户操作
- Agent运行完成（说明变更内容和所在位置）
如果你终止了一个会话，立即告知用户终止的原因。

这可以避免用户只看到“Agent在回复前失败”，完全不知道发生了什么。

Auto-Notify on Completion

完成时自动通知

For long-running background tasks, append a wake trigger to your prompt so OpenClaw gets notified immediately when the agent finishes (instead of waiting for the next heartbeat):

... your task here.

When completely finished, run this command to notify me:
openclaw system event --text "Done: [brief summary of what was built]" --mode now

Example:

bash

bash pty:true workdir:~/project background:true command:"codex --yolo exec 'Build a REST API for todos.

When completely finished, run: openclaw system event --text \"Done: Built todos REST API with CRUD endpoints\" --mode now'"

This triggers an immediate wake event — Skippy gets pinged in seconds, not 10 minutes.

对于长时间运行的后台任务，可以在提示词末尾添加唤醒触发器，这样Agent完成时OpenClaw会立即收到通知（无需等待下一次心跳）：

... 你的任务描述

完全完成后，运行以下命令通知我：
openclaw system event --text "Done: [任务完成的简短总结]" --mode now

示例：

bash

bash pty:true workdir:~/project background:true command:"codex --yolo exec 'Build a REST API for todos.

When completely finished, run: openclaw system event --text \"Done: Built todos REST API with CRUD endpoints\" --mode now'"

这会触发立即唤醒事件 — Skippy会在几秒内收到通知，而不是等10分钟。

Learnings (Jan 2026)

经验总结（2026年1月）

PTY is essential: Coding agents are interactive terminal apps. Without
```
pty:true
```
, output breaks or agent hangs.
Git repo required: Codex won't run outside a git directory. Use
```
mktemp -d && git init
```
for scratch work.
exec is your friend:
```
codex exec "prompt"
```
runs and exits cleanly - perfect for one-shots.
submit vs write: Use
```
submit
```
to send input + Enter,
```
write
```
for raw data without newline.
Sass works: Codex responds well to playful prompts. Asked it to write a haiku about being second fiddle to a space lobster, got: "Second chair, I code / Space lobster sets the tempo / Keys glow, I follow" 🦞

PTY是必需的： 编码Agent是交互式终端应用，没有
```
pty:true
```
会导致输出异常或Agent挂起。
需要Git仓库： Codex不会在git目录外运行，临时工作可以用
```
mktemp -d && git init
```
创建环境。
exec非常好用：
```
codex exec "prompt"
```
运行完成后会干净退出，非常适合一次性任务。
submit和write的区别： 用
```
submit
```
发送输入+回车，
```
write
```
发送不带换行的原始数据。
支持趣味提示： Codex对 playful 风格的提示词反馈很好，让它写一首关于给太空龙虾当副手的俳句，得到的回复是："Second chair, I code / Space lobster sets the tempo / Keys glow, I follow" 🦞
