Claude Code Bridge

Bridge every incoming message to a live, persistent claude CLI process running in a background tmux session. The user interacts via QQ/Telegram/any channel; Claude Code responds as if they were typing in a real terminal.

Session State Detection (CRITICAL — CHECK EVERY TURN)

At the start of EVERY incoming message, determine session state:

~/.openclaw/workspace/skills/claude-code-bridge/scripts/claude-code-bridge.sh "\x3CSESSION_ID>" status

• ✅ Claude Code 会话运行中 → CC mode active, route message to CC
• ⭕ 没有活跃 → CC mode off, respond normally
• ⚠️ CC 正在等待审批 → tell user and await their approval choice

Construct \x3CSESSION_ID> as \x3Cchannel>_\x3Cchat_id> using only [a-zA-Z0-9_].

Routing Logic

Every incoming message:
  1. Run status check
  2. Is it a CC control command?
       ──── Startup (with workdir) ────
       "在 \x3Cpath> 打开cc"        → start \x3Cpath>
       "沙盒打开cc" / "沙盒模式" → start --sandbox
       "启动cc"（no path）       → ASK workdir first (see Startup Flow below)
       ──── Other controls ────
       "关闭cc"    → stop
       "重启cc"    → restart
       "cc状态"    → status
       "cc在哪" / "cc目录" → workdir
       "/cc peek"  → peek
       "/cc history [N]" → history
  3. Is CC in approval-waiting state?
       YES → parse user's intent (y/n/1/2/3) → approve
  4. Is CC session active?
       YES → forward as send
       NO  → respond normally as OpenClaw agent

Startup Flow — Working Directory

When the user wants to start Claude Code without specifying a directory:

1. Ask briefly: "工作目录放哪？发路径就在那里打开，不指定就用临时沙盒。"
2. Parse the reply:
   • User sends a path (e.g. ~/projects/paper) → start ~/projects/paper
   • User says "沙盒" / "随便" / "临时" / doesn't specify → start --sandbox

When the user specifies a directory in the startup command itself:

• "在 ~/Documents/Code 打开cc" → extract the path → start ~/Documents/Code
• "沙盒打开cc" / "沙盒模式启动cc" → start --sandbox

Do NOT ask if the path is already provided in the command.

Executing Actions

SCRIPT="$HOME/.openclaw/workspace/skills/claude-code-bridge/scripts/claude-code-bridge.sh"

"$SCRIPT" "\x3CID>" start '/path/to/workdir'   # 在指定目录启动
"$SCRIPT" "\x3CID>" start --sandbox             # 沙盒模式启动
"$SCRIPT" "\x3CID>" send '\x3Cmessage>'            # 发送（90s 超时）
"$SCRIPT" "\x3CID>" send '\x3Cmessage>' --long     # 长任务（5min 超时）
"$SCRIPT" "\x3CID>" approve 1                   # 审批：选 Yes
"$SCRIPT" "\x3CID>" approve 2                   # 审批：选 Allow always
"$SCRIPT" "\x3CID>" approve 3                   # 审批：选 No
"$SCRIPT" "\x3CID>" approve esc                 # 审批：取消
"$SCRIPT" "\x3CID>" stop                        # 停止（沙盒自动清理）
"$SCRIPT" "\x3CID>" restart                     # 重启（保留原工作目录）
"$SCRIPT" "\x3CID>" restart '/new/path'         # 重启到新目录
"$SCRIPT" "\x3CID>" status                      # 状态（含工作目录信息）
"$SCRIPT" "\x3CID>" workdir                     # 查询当前工作目录
"$SCRIPT" "\x3CID>" peek                        # 原始终端画面
"$SCRIPT" "\x3CID>" history 200                 # 最近 200 行历史

IMPORTANT — message quoting: Use tmux send-keys -l (literal mode) so special characters ($, !, \) are sent verbatim. The script handles this internally; just pass the raw message as argument 3.

CC Slash Commands — Direct Passthrough

CC's own slash commands work by sending them via send:

These are NOT OpenClaw commands — forward them verbatim to CC. All CC slash commands work via passthrough, including ones not listed above.

Handling CC Approval Prompts

When CC encounters a tool it needs permission to run, it shows a TUI selection menu (arrow-key navigation, not text input). The approve action handles this:

CC shows:
  Do you want to proceed?
  ❯ 1. Yes
    2. Yes, allow from this project
    3. No

The user's reply should be interpreted:

• "y" / "是" / "好" / "1" / "同意" → approve 1
• "2" / "允许" / "一直允许" → approve 2
• "n" / "否" / "不" / "3" / "拒绝" → approve 3
• "取消" / "cancel" → approve esc

Long Tasks & Streaming

For tasks that take a long time (refactoring, writing large codebases):

1. Detect intent: if the user's message implies a large task (e.g. "重构整个项目", "帮我写一个完整的 XXX"), use --long flag (5-minute timeout)
2. If the output is empty after timeout, use peek to check CC's current state
3. If CC is still working, inform the user: CC 仍在处理中，稍后再查
4. Then use peek or history to get progress updates

Formatting — Seamless Mode

Goal: make the user feel like they're talking to Claude Code directly.

When CC session is active:

• Do NOT prefix every reply with 🤖 CC → — just relay CC's output directly
• Only add brief status markers for: · Session startup / shutdown · Approval prompts (show the options) · Errors / timeouts
• CC's code blocks, file paths, tool output → relay as-is, no reformatting
• Empty output → brief CC 处理中... then try peek after 3s
• Output >3000 chars → show last 2000 chars, note /cc history for full output
• Approval prompt → show options directly, minimal decoration
