PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Sensitive information exposure Description: Printing PII-like fields (user name and country) to stdout can lead to sensitive information exposure in logs; consider structured logging with redaction or omit sensitive fields. sample_code.py [81-82] Referred Code print(f"Creating user {profile.name} from {profile.country}") return {"name": profile.name, "email": profile.email}
	Secret handling in CI Description: Use of pipeline environment variable for API key may expose secrets in logs if downstream commands echo env; ensure commands do not print the token and mask logs. jenkins-pipeline.groovy [3-15] Referred Code environment { QODO_API_KEY = credentials('qodo-api-key') } stages { stage('Clean Code Check') { steps { script { sh 'npm install -g @qodo-ai/command' sh 'qodo clean_code --set files="." --set language="python" --set report_format="json"' } } } }
	Secret handling in CI Description: GitHub Actions job passes an API key via environment; ensure steps and the agent avoid printing the secret and that repository has secrets masking enabled. github-actions.yml [14-25] Referred Code - name: Install Qodo run: npm install -g @qodo-ai/command - name: Run Clean Code Agent run: | qodo clean_code \ --set files="." \ --set language="python" \ --set report_format="json" \ --set generate_docstrings=true env: QODO_API_KEY: ${{ secrets.QODO_API_KEY }}
	Secret handling in CI Description: GitLab CI exposes API key via variable; verify mask/protect flags are set and that command outputs do not leak the secret. gitlab-ci.yml [8-12] Referred Code - npm install -g @qodo-ai/command - qodo clean_code --set files="." --set language="python" --set report_format="json" variables: QODO_API_KEY: $QODO_API_KEY rules:
	Secret handling in CI Description: Azure DevOps pipeline passes API key env; ensure variable is marked secret and outputs are masked to prevent leakage in logs. azure-devops.yml [17-21] Referred Code - script: | qodo clean_code --set files="." --set language="python" --set report_format="json" displayName: 'Run Clean Code Agent' env: QODO_API_KEY: $(QODO_API_KEY)

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
High-level	Agent duplicates existing mature tooling The agent's functionality, such as checking for code smells and naming conventions, duplicates existing deterministic tools like linters. This introduces unpredictability into CI/CD pipelines. The agent should instead focus on unique capabilities like identifying architectural flaws or complex logic issues. Examples: agents/clean-code-agent/agent.toml [9-16] **Core Analysis Task:** Analyze the provided source code files for readability, maintainability, and structure. For each issue, provide the file path, line number, a clear description, and a 'diff-style' refactoring preview. You should look for: - **Meaningful Naming:** Unclear variable, function, or class names. - **Function Complexity:** Functions that are too long or have too many responsibilities. - **Code Smells:** Duplicated code, dead code, long parameter lists. - **Documentation Quality:** Unclear, outdated, or redundant comments. Solution Walkthrough: Before: # agent.toml instructions = """ You are an expert AI assistant... Analyze the provided source code files for readability, maintainability, and structure.

""" After: # agent.toml instructions = """ You are an expert AI assistant specializing in advanced code analysis. Your goal is to identify issues that traditional linters and static analysis tools often miss. You should look for: - **Architectural Smells:** Poor separation of concerns, cyclic dependencies. - **Complex Logical Flaws:** Potential race conditions, inefficient algorithms. - **API Design Issues:** Inconsistent API patterns, non-intuitive function signatures. ... Assume basic linting has already been performed. Focus your analysis on higher-level conceptual and structural problems. """ Suggestion importance[1-10]: 9 __ Why: This is a critical high-level suggestion that correctly identifies a fundamental design weakness—the agent's core tasks overlap with mature, deterministic tools, making it potentially unreliable for CI/CD—and proposes a valuable strategic pivot.

Possible issue	Fix invalid character in import Fix the invalid import path in test_utils.py.
