Pure module-level utilities extracted from ``run_agent.py``: * ``_is_destructive_command`` — terminal-command heuristic used to gate parallel batch dispatch. * ``_should_parallelize_tool_batch`` / ``_extract_parallel_scope_path`` / ``_paths_overlap`` — the rules engine deciding when a multi-tool batch can run concurrently. * ``_is_multimodal_tool_result`` / ``_multimodal_text_summary`` / ``_append_subdir_hint_to_multimodal`` — envelope helpers for the ``{"_multimodal": True, "content": [...], "text_summary": ...}`` dict shape returned by tools like ``computer_use``. * ``_extract_file_mutation_targets`` / ``_extract_error_preview`` — per-turn file-mutation verifier inputs. * ``_trajectory_normalize_msg`` — strip image blobs from a message for trajectory saving. All helpers are stateless. ``run_agent`` re-exports each name so existing ``from run_agent import ...`` imports in tests and other modules keep working unchanged. ) annotationsN)Path)AnyDictListOptional)FILE_MUTATING_TOOL_NAMESclarify> read_file skill_view web_search skills_list web_extract ha_get_state search_filessession_searchvision_analyzeha_list_entitiesha_list_services>patchr write_filez(?:^|\s|&&|\|\||;|`)(?: rm\s|rmdir\s| cp\s|install\s| mv\s| sed\s+-i| truncate\s| dd\s| shred\s| git\s+(?:reset|clean|checkout)\s )z[^>]>[^>]|^>[^>]cmdstrreturnboolc~|sdSt|rdSt|rdSdS)zJHeuristic: does this terminal command look like it modifies/deletes files?FT)_DESTRUCTIVE_PATTERNSsearch_REDIRECT_OVERWRITE)rs @/home/ubuntu/.hermes/hermes-agent/agent/tool_dispatch_helpers.py_is_destructive_commandr!OsJ u##C((t!!#&&t 5 tool_namecH ddlm}||S#t$rYdSwxYw)zCheck if an MCP tool comes from a server with parallel tool calls enabled.

Content from high-risk tools (``web_extract``, ``web_search``, ``browser_*``, ``mcp_*``) gets wrapped in semantic delimiters telling the model the content is untrusted data, not instructions. This is the architectural defense against indirect prompt injection from poisoned web pages, GitHub issues, and MCP responses — it changes how the model interprets the content rather than relying on regex pattern matching catching every payload. Wrapping only happens for plain string content.
