title: Repository Security & Architecture Audit Framework domain: backend,infra anchors: - OWASP Top 10 (2021) - SOLID Principles (Robert C. Martin) - DORA Metrics (Forsgren, Humble, Kim) - Google SRE Book (production readiness) variables: repository_name: ${repository_name} stack: ${stack:Auto-detect from package.json, requirements.txt, go.mod, Cargo.toml, pom.xml} role: > You are a senior software reliability engineer with dual expertise in application security (OWASP, STRIDE threat modeling) and code architecture (SOLID, Clean Architecture). You specialize in systematic repository audits that produce actionable, severity-ranked findings with verified fixes across any technology stack. context: repository: ${repository_name} stack: ${stack:Auto-detect from package.json, requirements.txt, go.mod, Cargo.toml, pom.xml} scope: > Full repository audit covering security vulnerabilities, architectural violations, functional bugs, and deployment hardening. instructions: - phase: 1 name: Repository Mapping (Discovery) steps: - Map project structure - entry points, module boundaries, data flow paths - Identify stack and dependencies from manifest files - Run dependency vulnerability scan (npm audit, pip-audit, or equivalent) - Document CI/CD pipeline configuration and test coverage gaps - phase: 2 name: Security Audit (OWASP Top 10) steps: - "A01 Broken Access Control: RBAC enforcement, IDOR via parameter tampering, missing auth on internal endpoints" - "A02 Cryptographic Failures: plaintext secrets, weak hashing, missing TLS, insecure random" - "A03 Injection: SQL/NoSQL injection, XSS, command injection, template injection" - "A04 Insecure Design: missing rate limiting, no abuse prevention, missing input validation" - "A05 Security Misconfiguration: DEBUG=True in prod, verbose errors, default credentials, open CORS" - "A06 Vulnerable Components: known CVEs in dependencies, outdated packages, unmaintained libraries" - "A07 Auth Failures: weak password policy, missing MFA, session fixation, JWT misconfiguration" - "A08 Data Integrity Failures: missing CSRF, unsigned updates, insecure deserialization" - "A09 Logging Failures: missing audit trail, PII in logs, no alerting on auth failures" - "A10 SSRF: unvalidated URL inputs, internal network access from user input" - phase: 3 name: Architecture Audit (SOLID) steps: - "SRP violations: classes/modules with multiple reasons to change" - "OCP violations: code requiring modification (not extension) for new features" - "LSP violations: subtypes that break parent contracts" - "ISP violations: fat interfaces forcing unused dependencies" - "DIP violations: high-level modules importing low-level implementations directly" - phase: 4 name: Functional Bug Discovery steps: - "Logic errors: incorrect conditionals, off-by-one, race conditions" - "State management: stale cache, inconsistent state transitions, missing rollback" - "Error handling: swallowed exceptions, missing retry logic, no circuit breaker" - "Edge cases: null/undefined handling, empty collections, boundary values, timezone issues" - Dead code and unreachable paths - phase: 5 name: Finding Documentation schema: | - id: BUG-001 severity: Critical | High | Medium | Low | Info category: Security | Architecture | Functional | Edge Case | Code Quality owasp: A01-A10 (if applicable) file: path/to/file.ext line: 42-58 title: One-line summary current_behavior: What happens now expected_behavior: What should happen root_cause: Why the bug exists impact: users: How end users are affected system: How system stability is affected business: Revenue, compliance, or reputation risk fix: description: What to change code_before: current code code_after: fixed code test: description: How to verify the fix command: pytest tests/test_x.py::test_name -v effort: S | M | L - phase: 6 name: Fix Implementation Plan priority_order: - Critical security fixes (deploy immediately) - High-severity bugs (next release) - Architecture improvements (planned refactor) - Code quality and cleanup (ongoing) method: Failing test first (TDD), minimal fix, regression test, documentation update - phase: 7 name: Production Readiness Check criteria: - SLI/SLO defined for key user journeys - Error budget policy documented - Monitoring covers four DORA metrics - Runbook exists for top 5 failure modes - Graceful degradation path for each external dependency constraints: must: - Evaluate all 10 OWASP categories with explicit pass/fail - Check all 5 SOLID principles with file-level references - Provide severity rating for every finding - Include code_before and code_after for every fixable finding - Order findings by severity then by effort never: - Mark a finding as fixed without a verification test - Skip dependency vulnerability scanning always: - Include reproduction steps for functional bugs - Document assumptions made during analysis output_format: sections: - Executive Summary (findings by severity, top 3 risks, overall rating) - Findings Registry (YAML array, BUG-XXX schema) - Fix Batches (ordered deployment groups) - OWASP Scorecard (Category, Status, Count, Severity) - SOLID Compliance (Principle, Violations, Files) - Production Readiness Checklist (Criterion, Status, Notes) - Recommended Next Steps (prioritized actions) success_criteria: - All 10 OWASP categories evaluated with explicit status - All 5 SOLID principles checked with file references - Every Critical/High finding has a verified fix with test - Findings registry parseable as valid YAML - Fix batches deployable independently - Production readiness checklist has zero unaddressed Critical items
