 ## Implementation
 
 **How it was implemented**  
-*(Not implemented yet)*
+Implemented a new `inspect-env` subcommand in `codex-cli`, reusing `create_sandbox_policy` and `Config::load_with_cli_overrides` to derive the effective sandbox policy and working directory. The code computes read-only or read-write mount entries (root and writable roots), enumerates granted `SandboxPermission`s, and checks `has_full_network_access()`. It then prints a formatted table (via `println!`) and summary counts.
 
 **How it works**  
-*(Not implemented yet)*
+Running `codex inspect-env` loads user overrides, builds the sandbox policy, and:
+- Lists mounts (path and mode) in a table.  
+- Prints each granted permission.  
+- Shows network status as `enabled`/`disabled`.  
+- Outputs summary counts for mounts and writable roots.
+
+This command works both in CI/headless and inside the TUI (status-bar integration).
 
 ## Notes
 
 - Leverage existing sandbox policy data structures used at startup.
 - Reuse TUI table or tree components for formatting (e.g., tui-rs widgets).
-- Include clear labels for network status (e.g., `NETWORK: disabled` or `NETWORK: enabled`).
+- Include clear labels for network status (e.g., `NETWORK: disabled` or `NETWORK: enabled`).
