From 53ba52d2fbf10b436a7b233d8f4907fd65f9ef2f Mon Sep 17 00:00:00 2001 From: yangyuan Date: Thu, 13 Aug 2026 15:34:38 +0800 Subject: [PATCH] feat(security): add permission modes for Full Access/Auto/Strict Introduce PermissionModeController presets, legacy migration, Global baseline protection, pattern-only HITL persist, builtin hard-Deny grading, NetworkGuard, and behavior findings while keeping the dual-pipeline engine mounted under Full Access. Also inject package builtin sensitive_paths (ask|deny floor) into Auto/Strict file_guard. --- openjiuwen/harness/deep_agent.py | 3 +- .../rails/security/tool_security_rail.py | 376 +++++++++++--- .../harness/resources/builtin_rules.yaml | 296 +++++++++-- openjiuwen/harness/security/__init__.py | 24 +- .../harness/security/ask_presentation.py | 210 ++++++++ .../harness/security/builtin_platforms.py | 72 +++ openjiuwen/harness/security/core.py | 40 +- openjiuwen/harness/security/factory.py | 38 +- openjiuwen/harness/security/file_guard.py | 8 +- openjiuwen/harness/security/files/extract.py | 2 +- openjiuwen/harness/security/findings.py | 141 +++++ openjiuwen/harness/security/host.py | 26 +- openjiuwen/harness/security/mode.py | 57 ++ .../harness/security/mode_controller.py | 490 ++++++++++++++++++ openjiuwen/harness/security/mode_presets.py | 58 +++ openjiuwen/harness/security/models.py | 39 +- openjiuwen/harness/security/network_guard.py | 97 ++++ openjiuwen/harness/security/patterns.py | 182 ++++++- .../harness/security/sensitive_paths.py | 84 +++ openjiuwen/harness/security/suggestions.py | 22 +- openjiuwen/harness/security/tiered_policy.py | 223 +++++++- .../harness/security/test_allow_tools_hitl.py | 123 +++++ .../harness/security/test_ask_presentation.py | 118 +++++ .../security/test_builtin_platforms.py | 53 ++ .../security/test_builtin_sensitive_paths.py | 153 ++++++ .../security/test_file_guard_persist.py | 7 + .../security/test_findings_simple_compound.py | 88 ++++ .../security/test_path_policy_a_b_split.py | 14 +- ...est_permission_merge_after_auto_confirm.py | 39 +- .../test_permission_mode_controller.py | 325 ++++++++++++ .../harness/security/test_permission_p1.py | 246 +++++++++ .../test_powershell_and_path_auto_confirm.py | 147 ++++++ .../security/test_shell_pipeline_segments.py | 150 ++++++ 33 files changed, 3723 insertions(+), 228 deletions(-) create mode 100644 openjiuwen/harness/security/ask_presentation.py create mode 100644 openjiuwen/harness/security/builtin_platforms.py create mode 100644 openjiuwen/harness/security/findings.py create mode 100644 openjiuwen/harness/security/mode.py create mode 100644 openjiuwen/harness/security/mode_controller.py create mode 100644 openjiuwen/harness/security/mode_presets.py create mode 100644 openjiuwen/harness/security/network_guard.py create mode 100644 openjiuwen/harness/security/sensitive_paths.py create mode 100644 tests/unit_tests/harness/security/test_allow_tools_hitl.py create mode 100644 tests/unit_tests/harness/security/test_ask_presentation.py create mode 100644 tests/unit_tests/harness/security/test_builtin_platforms.py create mode 100644 tests/unit_tests/harness/security/test_builtin_sensitive_paths.py create mode 100644 tests/unit_tests/harness/security/test_findings_simple_compound.py create mode 100644 tests/unit_tests/harness/security/test_permission_mode_controller.py create mode 100644 tests/unit_tests/harness/security/test_permission_p1.py create mode 100644 tests/unit_tests/harness/security/test_powershell_and_path_auto_confirm.py create mode 100644 tests/unit_tests/harness/security/test_shell_pipeline_segments.py diff --git a/openjiuwen/harness/deep_agent.py b/openjiuwen/harness/deep_agent.py index 71e772c06..c8af7d487 100644 --- a/openjiuwen/harness/deep_agent.py +++ b/openjiuwen/harness/deep_agent.py @@ -603,7 +603,8 @@ def _queue_pending_rails(self, config: DeepAgentConfig) -> None: if config.enable_task_loop: self._pending_rails.append(TaskCompletionRail()) -
