1. Missing guardrails required files 📎 Requirement gap ⚙ Maintainability
The new operator_use/guardrails/ package does not include the required module files (action_validator.py, content_filter.py, policy_engine.py, registry.py) and instead introduces filters.py/policies.py, so the mandated package structure/public API is not met. This breaks the expected import surface and blocks downstream integration work.
Agent Prompt
## Issue description
The guardrails package does not match the required file/module structure and public API expected by the compliance checklist (missing `action_validator.py`, `content_filter.py`, `policy_engine.py`, `registry.py`).
## Issue Context
Current implementation places multiple responsibilities in `base.py` and uses `filters.py`/`policies.py`, which does not satisfy the required foundation layout for Phase 1 integration.
## Fix Focus Areas
- operator_use/guardrails/__init__.py[1-4]
- operator_use/guardrails/base.py[1-53]
- operator_use/guardrails/filters.py[1-25]
- operator_use/guardrails/policies.py[1-17]

2. policyengine.assess() wrong interface 📎 Requirement gap ✓ Correctness
The guardrails interfaces do not match the required signatures/objects: ContentFilter.filter() lacks a context parameter, there is no ActionValidator.validate(...), and PolicyEngine provides assess(...) instead of classify_risk(action) returning safe|review|dangerous. This prevents building compatible guardrail plugins and violates the required interface contract.
Agent Prompt
## Issue description
Guardrails base interfaces and engine method names/signatures do not match the required contract (missing `ActionValidator`, missing `GuardrailResult`, wrong `ContentFilter.filter` signature, and `PolicyEngine.assess` vs required `classify_risk`).
## Issue Context
Downstream integrations/tests will rely on the required method names and the `safe|review|dangerous` classification contract.
## Fix Focus Areas
- operator_use/guardrails/base.py[1-53]

3. No guardrails registry mechanism 📎 Requirement gap ⚙ Maintainability
There is no registry that supports registration and lookup of guardrails/policies; PolicyEngine only stores an in-memory list via add_policy with no named/type lookup API. This prevents independently registering and retrieving guardrails for configuration and runtime integration.
Agent Prompt
## Issue description
A registry for guardrails (registration + lookup) is required but not implemented; current code only supports `PolicyEngine.add_policy()` with no retrieval by name/type/category.
## Issue Context
Registry support is needed for integration/configuration so agents can select guardrails and tests can query registered components deterministically.
## Fix Focus Areas

- operator_use/guardrails/__init__.py[1-4]

Hey @richard-devbot, this PR has merge conflicts with main. Could you rebase |
Comprehensive design document covering 5 phases (76 issues): - Phase 0: CI/CD, test infrastructure, AI principles framework - Phase 1: Critical security fixes (path traversal, JS injection, terminal, auth) - Phase 2: AI guardrails & responsible AI (prompt injection, content filtering, ethics) - Phase 3: Performance benchmarks & optimization - Phase 4: Comprehensive QA (unit, e2e, adversarial, fuzzing, CI hardening) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Addresses CWE-78 (OS Command Injection). Both occurrences in control_center.py and tui.py now use subprocess.run() with shell=True, check=False instead of os.system(). Closes CursorTouch#19 Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
- Add bandit SAST scan step to test job (closes CursorTouch#3) - Add gitleaks secret detection as parallel secrets job (closes CursorTouch#4) - Add pip-audit dependency scanning as parallel audit job (closes CursorTouch#5) - Add pytest-cov coverage reporting with codecov upload (closes CursorTouch#6) - Add CI badge to README.md (closes CursorTouch#2) - Add bandit, pip-audit, pytest-cov to dev dependencies Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
Implements GitHub issues CursorTouch#11 and CursorTouch#12: - AI_PRINCIPLES.md: documents 6 core safety principles (least privilege, human oversight, transparency, containment, privacy by default, fail safe) with a development checklist for pre-merge security review. - operator_use/guardrails/: new module providing ActionPolicy, ContentFilter, PolicyEngine, and RiskLevel abstractions. Includes DefaultPolicy for built-in tool risk classification and CredentialFilter for masking API keys in logs and LLM context. Closes CursorTouch#11, closes CursorTouch#12 Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
Scaffold test directories for issues CursorTouch#7 and CursorTouch#10: - tests/security/: path traversal, terminal command, gateway auth tests with helpers for traversal/injection payloads (all skipped pending fixes) - tests/e2e/: message pipeline tests (all skipped pending full stack) 12 tests collected, 0 errors. All skipped with tracking references. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

…I cache - policies.py: Fix browser tool misclassification — tool is 'browser' with action arg, not 'browser_script'/'browser_navigate'. script/download => DANGEROUS, navigation/interaction => REVIEW (CWE-78 + CWE-22) - helpers.py + SECURITY_ROADMAP.md: Replace startswith() with is_relative_to() for path containment checks — startswith has prefix-collision vulnerability where /workspace_evil passes startswith(/workspace) - ci.yml: Add enable-cache: true to both test and audit setup-uv steps Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
bandit: - Remove shell=True from control_center.py and tui.py — pass ["cls"]/["clear"] as list args, no shell needed (resolves B602 HIGH) - Add [tool.bandit] config to pyproject.toml: skip B104 (0.0.0.0 is intentional LAN server binding), exclude generated vendored dirs - Add nosec B324 to restart.py MD5 (filename only, not security) - Add nosec B310 to fal/openai/together image providers (HTTPS API URLs only) - Pass -c pyproject.toml in CI so config is loaded gitleaks: - Replace gitleaks-action@v2 (requires paid org license for orgs) with free gitleaks CLI v8.24.3 downloaded at runtime pip-audit: - Upgrade cryptography → 46.0.6, pyasn1 → 0.6.3, requests → 2.33.1, tornado → 6.5.5 (all have CVE fixes available) - Add --ignore-vuln CVE-2026-4539 for pygments (ReDoS, no fix released yet) Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
The control_center function was hardcoding graceful_fn=None when calling _do_restart(), ignoring the _graceful_restart_fn kwarg injected by start.py. This caused test_restart_calls_graceful_fn_not_os_exit to fail and meant graceful shutdown was never used even when wired. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

All 19 ruff violations were pre-existing on upstream main: - F541: remove spurious f-prefix on string literals (mcp.py, skill.py, test_mcp_integration.py) - F401: remove unused imports (Path, MCPServerConfig, Any, uuid, inspect, field) - F821: add TYPE_CHECKING guard for MCPManager in cli/start.py - F811: remove duplicate Path import in cli/start.py - F841: prefix unused test variables with _ (mock_session, tool_names) Bump aiohttp 3.9.0 -> 3.13.5 to resolve 10 pip-audit CVEs: CVE-2026-34513 through CVE-2026-34525 (all fixed in 3.13.4+)
BrowserPlugin and ComputerPlugin no longer register hooks to the main agent — subagents manage their own state injection. Test assertions updated accordingly: - Remove stale XML-tag assertions from SYSTEM_PROMPT tests - Fix browser tool name: 'browser' -> 'browser_task' - Update hook tests: register_hooks() is now a no-op for main agent, so assertions verify hooks are NOT wired (not that they are)
