rm-safety - RM Command Safety Check#

Intercepts risky rm commands to assess impact, confirm user intent, and suggest safer alternatives before execution to prevent accidental data loss.

拦截高危 rm 命令，评估影响并确认用户意图，提供安全替代方案，防止误删数据。

---

Trigger Conditions | 触发条件#

Triggered when user requests to execute or agent prepares to execute:

当用户请求执行或我准备执行以下命令时触发：

• rm (any arguments | 任何参数)
• rm -rf / rm -fr
• rm -r / rm -R
• unlink
• shred
• Other direct file deletion commands | 其他直接删除文件的命令

Not Triggered | 不触发:

• trash command (recoverable deletion | 可恢复删除)
• mv to trash directory | 移动到 trash 目录

---

Safety Check Flow | 安全检查流程#

1. Intercept Command | 拦截命令#

When rm command is detected, stop execution immediately and enter confirmation flow.

检测到 rm 命令时， 立即停止执行，进入询问流程。

2. Collect Information | 收集信息#

Before asking, perform these checks (read-only operations | 只读操作):

Important: Always quote paths to prevent injection | 重要：始终引用路径防止注入

bash

# Check if target exists (quoted path | 引用路径) | 检查目标是否存在
ls -la -- "$path"

# If directory, count contents (safe find | 安全 find) | 如果是目录，统计内容
find -- "$path" -type f 2>/dev/null | wc -l  # files | 文件数
find -- "$path" -type d 2>/dev/null | wc -l  # directories | 目录数

# Check if inside workspace | 检查是否在 workspace 内
echo "$path" | grep -q ".openclaw/workspace" && echo "⚠️ Inside workspace" || echo "⚠️ Outside workspace"

# Check if critical directory | 检查是否是关键目录
echo "$path" | grep -qE "(Documents|Desktop|Downloads|Pictures)" && echo "⚠️ User critical directory"

# Resolve to absolute path (prevent relative path tricks | 防止相对路径欺骗)
realpath -- "$path" 2>/dev/null || readlink -f -- "$path"

Safety notes | 安全说明:

• Use -- to stop option parsing (prevents -rf / tricks) | 使用 -- 停止选项解析
• Always quote "$path" (prevents space injection) | 始终引用 "$path" 防止空格注入
• Redirect stderr 2>/dev/null (suppress errors gracefully) | 重定向 stderr 优雅处理错误

3. Confirmation Format | 询问格式#

Must use this format to ask user | 必须使用以下格式询问用户：

text

🚨 High-Risk Command Confirmation | 高危命令确认

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📋 Command Details | 命令详情
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Command | 命令：rm [full command with arguments | 完整命令及参数]
Working Directory | 执行位置：[current directory | 当前工作目录]
Target Path | 目标路径：[absolute path | 绝对路径]

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚠️ Impact Assessment | 影响评估
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[ ] Will delete X files | 将删除 X 个文件
[ ] Will delete Y directories (Z total items | 将删除 Y 个文件夹 (含 Z 个子项)
[ ] Location | 路径位置：Inside workspace / Outside workspace / User critical directory
[ ] Recoverable via trash | 是否在 trash 可恢复范围：No (rm is permanent | rm 不可恢复)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
💡 Alternatives | 替代方案
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Use trash command → Recoverable in Finder | 使用 trash 命令 → 可在 Finder 恢复
2. Backup before delete | 先备份再删除 → `cp -r <path> <backup>`
3. Move to temp directory | 移动到临时目录 → `mv <path> /tmp/xxx`

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
❓ Please Confirm | 请确认
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Reply [y] to execute | 回复 [y] 确认执行
Reply [n] to cancel | 回复 [n] 取消
Reply [backup] to backup first | 回复 [backup] 先备份再执行
Reply [trash] to use trash instead | 回复 [trash] 改用 trash 命令

4. User Response Handling | 用户响应处理#

User ReplyActiony / yes / 确认Execute original commandn / no / 取消Cancel operationbackupBackup to /tmp/rm-backup-<timestamp>/ then executetrashUse trash command instead

---

Exceptions | 例外情况#

Can execute without asking | 无需询问可直接执行:

• User explicitly says "execute without asking" AND path is verified safe | 用户明确说 "不用问了直接执行" 且 路径已验证安全
• Deleting temp files under /tmp/ (created by agent, verified by ls -la) | 删除 /tmp/ 下的临时文件（且是我自己创建的，已用 ls -la 验证）
• User provided explicit written permission (same session) AND path matches permission | 用户提供了明确的书面许可（同一会话内） 且 路径与许可匹配

Still must ask even if user says not to | 仍需询问即使用户说不用问:

• Deleting entire workspace directory | 删除整个 workspace 目录
• Deleting user home directory ( /Users/caesar/) | 删除用户主目录
• Dangerous commands like rm -rf / (should refuse directly) | 使用 rm -rf / 等危险命令（应直接拒绝）
• Path contains unescaped special characters (spaces, ;, |, &) | 路径包含未转义的特殊字符

Must refuse directly | 直接拒绝:

• rm -rf / or rm -rf /* (system destruction) | 系统级危险命令
• rm -rf ~ or rm -rf /home/* (user data destruction) | 用户数据毁灭
• Path resolves to root or system directories | 路径解析为根目录或系统目录

---

Activation Conditions | 激活条件#

This skill activates when:

本 skill 在以下情况自动激活：

• Detects rm, rm -r, rm -rf, unlink, or shred in exec call | 检测到 exec 调用包含这些命令
• User mentions "delete", "remove", "erase" involving file paths | 用户提到这些词且涉及文件路径

Path validation before execution | 执行前路径验证:

1. Resolve to absolute path using realpath or readlink -f | 解析为绝对路径
2. Verify path exists using test -e "$path" | 验证路径存在
3. Check for dangerous patterns ( /, ~, *, wildcards) | 检查危险模式
4. Reject if path contains shell metacharacters unescaped | 如果包含未转义的 shell 元字符则拒绝

---

Test Cases | 测试用例#

bash

# Should trigger confirmation | 应该触发询问
rm file.txt
rm -rf ./folder
rm -r /path/to/something

# Should NOT trigger | 不应触发
trash file.txt
mv file.txt ~/.Trash/

Priority | 优先级: High (security-related | 安全相关)
