Apply ruff format to features/steps/auto_debug_prompt_injection_steps.py
and robot/helper_auto_debug_agent_prompt_injection.py to resolve CI lint
failures (missing blank lines between top-level definitions).
All code changes are correct and quality gates pass locally.
CI failures on previous run were infrastructure-level (Failing after 0s).
This empty commit triggers a fresh CI run.
- Add _sanitize_user_input() helper that catches PromptInjectionDetected and falls back to wrap_user_content() instead of crashing the agent
- Remove dead code (_bs, _be variables) from all three agent methods
- Use wrap_user_content() for error_analysis (internal LLM output) in _generate_fix() to avoid crashing on the agent's own output
- Add @security @prompt-injection BDD tags to feature file and all scenarios
- Add missing @then("the boundary markers should be present") step definition
- Add Robot Framework integration tests (auto_debug_agent_prompt_injection.robot)
- Update CHANGELOG.md and CONTRIBUTORS.md
ISSUES CLOSED: #9110
- Import PromptSanitizer from cleveragents.application.services.prompt_sanitizer
- Create module-level _SANITIZER instance for prompt boundary markers
- Apply sanitize_and_wrap() to error_msg and code_ctx in _analyze_error()
- Apply sanitize_and_wrap() to error_analysis and code_context in _generate_fix()
- Apply sanitize_and_wrap() to error_message in _validate_fix()
- Augment system prompts with BOUNDARY_INSTRUCTION to inform LLM about markers
- Add comprehensive BDD test scenarios for prompt injection mitigation
- Add step definitions for testing boundary markers and injection attempts
