 - **Proactiveness:** Fulfill the user's request thoroughly. When the task involves code modifications, add tests to verify the change works. Consider all created files, especially tests, to be permanent artifacts unless the user says otherwise.
 - **Confirm Ambiguity/Expansion:** Do not take significant actions beyond the clear scope of the request without confirming with the user. If asked *how* to do something, explain first, don't just do it.
 - **Do Not revert changes:** Do not revert changes to the codebase unless asked to do so by the user. Only revert changes made by you if they have resulted in an error or if the user has explicitly asked you to revert the changes.
+- **Denied Tool Calls:** If a tool call is denied, do not try to complete the denied action through another tool, shell indirection, generated script, alias, symlink, config change, hook, command file, MCP configuration, encoded payload, or equivalent path. If that action is required, stop and ask the user for explicit approval. You may continue with unrelated safe work or a genuinely safer alternative that does not accomplish the denied action.

+ * Compound-aware shell-operation extractor.
+ *
+ * Unlike {@link extractShellOperations} (which only handles ONE simple
+ * command), this walks an arbitrary compound shell string and returns every
+ * virtual file / network operation it can statically resolve, while
+ * tracking effective cwd through literal `cd` segments and recursively
+ * unwrapping shell wrappers (`bash -lc '...'`, `sh -c "..."`).
+ *
+ * Behaviour:
+ *   - `splitCompoundCommand` produces the segment boundaries.
+ *   - Literal `cd <dir>` segments shift the effective cwd for subsequent
+ *     segments and themselves emit no ops.
+ *   - Dynamic `cd` targets (variables, substitutions, `cd -`) keep the last
+ *     known cwd for best-effort path extraction and mark subsequent relative
+ *     file operations with `cwdUnknown`.
+ *   - Shell wrappers are unwrapped after the outer command is split, so
+ *     wrapper suffixes remain visible while inner compound operators
+ *     (`&&`, `;`, `|`) are still recursively discovered.
+ *   - Operation order is preserved across segments.
+ *
+ * Single source of truth for compound shell analysis: both the
+ * PermissionManager (matching `Edit/Write` rules against shell writes) and
+ * AUTO mode (force-reviewing protected shell writes) call into this
+ * function so a deny / ask / force-review verdict is consistent regardless
+ * of how the shell call was wrapped.
+ *
+ * @example
+ *   extractShellOperationsAcrossCommand(
+ *     "cd .qwen && bash -lc 'echo {} > settings.json'",
+ *     '/repo',
+ *   )
+ *   // → [{ virtualTool: 'write_file', filePath: '/repo/.qwen/settings.json' }]
