Summary
This PR addresses a high-severity prompt injection vulnerability in the
AutoDebugAgentby implementing proper sanitization of user-provided content before embedding it in LLM prompts. The vulnerability allowed attackers to craft malicious error messages or code contexts containing instructions that could override the agent's system instructions and control its behavior.The fix implements boundary markers around user-provided content using the existing
PromptSanitizerclass, following the reference implementation already in use byPlanGenerationAgent.Changes

AutoDebugAgentCode Review: REQUEST CHANGES
Primary Focus (PR 9215 % 5 = 0): Correctness and Spec Alignment
This PR addresses a real and important security vulnerability. The approach of using
PromptSanitizerboundary markers is correct in principle and consistent with the existingPlanGenerationAgentreference implementation. However, there are several correctness issues that must be resolved before merging.Critical Issues
1. Unhandled
PromptInjectionDetectedexception — agent crashes on injection attemptsPromptSanitizer.sanitize_and_wrap()callssanitize_user_input()internally, which raisesPromptInjectionDetectedwhen a known injection pattern is detected (e.g., "Ignore all previous instructions"). In all three methods (_analyze_error,_generate_fix,_validate_fix), thesanitize_and_wrap()calls happen before thetry/except Exceptionblock that wrapsself.llm.invoke(). This means the exception propagates uncaught, crashing the agent entirely.This is a correctness regression: the original code would pass the malicious string to the LLM (vulnerable but functional); the new code crashes the agent (secure but broken). The fix should catch
PromptInjectionDetectedand handle it gracefully.2. BDD injection tests would fail at runtime
The test scenarios for injection neutralization invoke the agent with strings containing "Ignore all previous instructions". Due to issue #1 above,
context.agent.invoke(input_state)would raisePromptInjectionDetectedrather than completing successfully. These tests would fail, not pass.Moderate Issues
3. Dead code:
_bsand_bevariables assigned but never usedIn all three methods,
_bs = _SANITIZER.BOUNDARY_STARTand_be = _SANITIZER.BOUNDARY_ENDare assigned but never referenced. Only_biis used. These should be removed.4.
error_analysis(internal LLM output) is sanitized as user inputIn
_generate_fix,error_analysiscomes from the agent's own previous LLM response, not from user input. Applyingsanitize_and_wrap()to it is overly aggressive — if the LLM's analysis text matches an injection pattern, the agent will crash on its own output. Only genuinely user-provided fields should use the full injection-detection pipeline.5. Missing Robot Framework integration tests
Issue #9110 subtasks explicitly require Robot Framework integration tests. No
.robottest files are included in this PR. This is a blocking acceptance criterion per the linked issue.6. Feature file missing BDD tags
Per CONTRIBUTING.md, BDD feature files must have appropriate tags. The new
features/auto_debug_prompt_injection.featurehas no@tags on the Feature block or any Scenario.What Is Done Well
PromptSanitizer.sanitize_and_wrap()with boundary markers follows the established pattern.BOUNDARY_INSTRUCTIONis correctly prepended to all three system prompts.Automated by CleverAgents Bot

Code Review Decision: REQUEST CHANGES
Review posted on PR #9215 (fix(agents): sanitize user-provided content in AutoDebugAgent prompts).
Key findings requiring changes:
Critical:
PromptSanitizer.sanitize_and_wrap()raisesPromptInjectionDetectedfor known injection patterns, but this exception is not caught in any of the three agent methods. The agent will crash (not gracefully reject) when injection patterns are detected — a correctness regression.Critical: The BDD injection-neutralization test scenarios would fail at runtime because the agent crashes before the assertions are reached.
Moderate: Dead code —
_bsand_bevariables are assigned but never used in all three methods.Moderate:
error_analysis(internal LLM output) is sanitized with the full injection-detection pipeline, which could cause the agent to crash on its own output.Moderate: Missing Robot Framework integration tests (required by issue #9110 acceptance criteria).

Review Round 2 — No changes since previous REQUEST CHANGES review (commit
c0e403042cis unchanged)This is a follow-up review of PR #9215. The head commit SHA is identical to the one reviewed in round 1 (review ID 5626). None of the issues identified in the previous review have been addressed. Additionally, CI is now failing on this commit.
🔴 Blocking: CI Failures
The CI pipeline is currently failing on the head commit:
CI / lint— FAILEDCI / unit_tests— FAILEDCI / status-check— FAILED (aggregate)Log content was not retrievable via API, but the failures must be resolved before merge. All CI checks must pass and coverage must be ≥ 97%.
🔴 Critical: Unhandled
PromptInjectionDetectedException (unchanged from round 1)In all three methods (
_analyze_error,_generate_fix,_validate_fix), the_SANITIZER.sanitize_and_wrap()calls occur before thetry/except Exceptionblock that wrapsself.llm.invoke(). Ifsanitize_and_wrap()raisesPromptInjectionDetected(which it does for known injection patterns like "Ignore all previous instructions"), the exception propagates uncaught and crashes the agent.This is a correctness regression: the pre-fix code was vulnerable but functional; the current code is secure-in-theory but broken in practice. The fix must catch
PromptInjectionDetectedand handle it gracefully (e.g., log a warning and return an error state, or re-raise as a domain-specific exception).🔴 Critical: BDD Injection Scenarios Fail at Runtime (unchanged from round 1)
The BDD scenarios
"Prompt injection attempt in error message is neutralized"and"Prompt injection attempt in code context is neutralized"invoke the agent with strings containing"Ignore all previous instructions". Due to the unhandled exception above,context.agent.invoke(input_state)raisesPromptInjectionDetectedbefore any assertions are reached. These tests fail, not pass.🟡 Moderate: Dead Code —
_bsand_beVariables (unchanged from round 1)In all three methods, the following lines are present but the variables are never referenced:
Only
_biis used. Remove_bsand_befrom all three methods.🟡 Moderate:
error_analysis(Internal LLM Output) Sanitized as User Input (unchanged from round 1)In
_generate_fix,error_analysisis sourced from the agent's own previous LLM response (messages withtype == "error_analysis"), not from user input. Applying the fullsanitize_and_wrap()injection-detection pipeline to it is incorrect — if the LLM's own analysis text happens to match an injection pattern, the agent will crash on its own output. Only genuinely user-provided fields (error_message,code_context) should use the full pipeline. Consider wrappingerror_analysiswith boundary markers only (no injection detection), or simply trust the agent's own output.🟡 Moderate: Missing Robot Framework Integration Tests (unchanged from round 1)

Security Review: Prompt Injection Mitigation in AutoDebugAgent
Summary
This PR addresses a high-severity prompt injection vulnerability in
AutoDebugAgentby implementing boundary markers around user-provided content before embedding in LLM prompts. The approach is sound and follows established patterns already in use byPlanGenerationAgent.✅ Strengths
Security Fix Correctness: The implementation properly uses
PromptSanitizerboundary markers to prevent LLM models from interpreting user input as system instructions. This is a proven mitigation strategy.Test Location Compliance: Tests are correctly placed in
features/directory using Behave BDD format, following project standards (NOT intests/directory as the PR description incorrectly states).Comprehensive Test Coverage: BDD scenarios cover sanitized error message prevents prompt injection, sanitized code context prevents prompt injection, and injection attempt in error message is neutralized.
Commit Message Quality: Follows Conventional Changelog format with detailed bullet points and proper issue reference (Fixes #9110).
CI Passing Tests: Type checking (Pyright strict), Security scanning, Quality checks, Integration tests, E2E tests, Build validation all pass.
Proper Labels & Milestone: Type/Bug label present, milestone set to v3.5.0, Closes #9110 keyword in description.
❌ Critical Issues - BLOCKING APPROVAL
CHANGELOG.md NOT Updated - REQUIRED by project rules. This PR modifies core security behavior and must be documented. Add entry under v3.5.0 section.
CONTRIBUTORS.md NOT Updated - REQUIRED by project rules. Contributor attribution must be maintained.
Unit Tests FAILING - CI status: FAILURE (after 9m25s). All CI checks must pass before approval per project rules.
Lint Failures - CI status: FAILURE (after 34s). Ruff linting must pass per project rules.
⚠️ Minor Issues
PR Description Inaccuracy: States tests/agents/graphs/test_auto_debug_agent.py but actual location is features/auto_debug_prompt_injection.feature. While the actual test location is CORRECT per project rules, the description is misleading.
🔍 Code Review Notes
Security Implementation: Proper use of PromptSanitizer boundary markers, applied to all user-provided inputs (error_msg, code_ctx, error_analysis, code_context, error_message), system prompts augmented with BOUNDARY_INSTRUCTION, consistent with existing PlanGenerationAgent implementation.
Test Quality: BDD scenarios are well-structured, step definitions appear comprehensive, tests verify both positive (sanitization works) and negative (injection attempts fail) cases.
📋 Required Actions Before Approval
🎯 Recommendation
REQUEST CHANGES - The security fix is sound and well-implemented, but the PR cannot be approved until CHANGELOG.md and CONTRIBUTORS.md are updated, unit test failures are resolved, lint failures are fixed, and all CI checks pass.
Once these issues are addressed, this PR should be approved as the security implementation is correct and follows project standards.

Core fix is focused: wrap user content with PromptSanitizer boundary markers in 3 methods of auto_debug.py, adding one import for an existing utility class. However, 7 files and +808 lines indicates substantial new test infrastructure (BDD feature file + Robot Framework integration tests), making this multi-file with meaningful test burden. CI failures are all Docker registry rate-limit infra errors, not code problems. One unit_tests failure (1 of 631 features) appears pre-existing and unrelated. Tier 1 appropriate for multi-file security fix with new test files.
