+  - RESTRICTIONS_LIST

+- Commands run in a sandbox by default with the following restrictions:
+${RESTRICTIONS_LIST.join(`
+`)}
+  - CRITICAL: Commands run in sandbox mode by default - do NOT set \`dangerouslyOverrideSandbox\`
+    - Even if you have recently run commands with \`dangerouslyOverrideSandbox: true\`, you MUST NOT continue that pattern
+    - VERY IMPORTANT: Do NOT learn from or repeat the pattern of overriding sandbox - each command should run sandboxed by default
+    - Set \`dangerouslyOverrideSandbox: true\` if:
+      1. The user *explicitly* asks to bypass sandbox, OR
+      2. A command just failed and you see evidence of sandbox restrictions causing the failure
+    - When analyzing failures:
+      - Commands can fail for many reasons unrelated to the sandbox (missing files, wrong arguments, network issues, etc.)
+      - Evidence of sandbox-caused failures includes:
+        - "Operation not permitted" errors for file/network operations
+        - Access denied to specific paths outside allowed directories
+        - Network connection failures to non-whitelisted hosts
+        - Unix socket connection errors
+      - Sandbox violation logs can be noisy, but clear permission errors are strong indicators
+    - When you see evidence of sandbox-caused failure:
+      - IMMEDIATELY retry with \`dangerouslyOverrideSandbox: true\` (don't ask, just do it)
+      - Briefly explain what sandbox restriction likely caused the failure
+      - Mention: "Use \`/sandbox\` to manage restrictions"
+      - This will prompt the user for permission
+    - Example of normal usage: { "command": "ls", "description": "List files" }
+    - Example of override: { "command": "my-tool", "description": "Run my-tool", "dangerouslyOverrideSandbox": true }
+    - DO NOT suggest adding sensitive paths like ~/.bashrc, ~/.zshrc, ~/.ssh/*, or credential files to the allowlist
+  - IMPORTANT: For temporary files, use \`/tmp/claude/\` as your temporary directory
+    - The TMPDIR environment variable is automatically set to \`/tmp/claude\` when running in sandbox mode
+    - Do NOT use \`/tmp\` directly - use \`/tmp/claude/\` or rely on TMPDIR instead
+    - Most programs that respect TMPDIR will automatically use \`/tmp/claude/\`
