From 8c937ace4003996aa9526be35fc7b66820088c2e Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 21 Dec 2025 16:57:50 +0000 Subject: [PATCH] feat: Comprehensive project improvements from 10-agent deep analysis ## Security Fixes (Agent 1) - Remove hardcoded API keys and passwords in test files - Replace eval() with ast.literal_eval() for safe evaluation - Fix CORS configuration with explicit headers whitelist - Update .gitignore for sensitive files ## Memory Leak Fixes (Agent 2) - Fix MetricsMiddleware using deque with max_history limit - Fix TokenTracker using deque with max_records limit - Optimize get_stats() from 4 iterations to 1 ## Dependency Management (Agent 3) - Remove unused dependencies (torch, transformers, numpy, pandas, etc.) - Move dev tools to requirements-dev.txt - Update outdated packages (anthropic, langchain) ## Test Enhancement (Agent 4) - Add comprehensive test_base_agent.py with 31 test cases - Cover initialization, response generation, error handling, timeouts ## Code Refactoring (Agent 5) - Create AgentPromptGenerator for centralized prompt management - Update BaseAgent to use prompt generator - Export new module in agents/__init__.py ## CI/CD Improvements (Agent 6) - Add GitHub Actions test.yml with linting, security scan, coverage - Update GitLab CI with mandatory test stage - Enforce 70% minimum coverage ## Monitoring & Alerting (Agent 7) - Create Prometheus alert rules for API, errors, latency, tasks - Create Alertmanager configuration with routing - Add infrastructure alerts for pods, memory, CPU ## Configuration Management (Agent 8) - Create .env.development and .env.production templates - Create ConfigValidator for startup validation - Fix docker-compose.yml hardcoded passwords ## Documentation (Agent 9) - Create CONTRIBUTING.md with development guidelines - Create SECURITY.md with vulnerability reporting policy - Update CHANGELOG.md with version history ## Error Handling (Agent 10) - Create APIErrorResponse for unified error responses - Create retry_utils with async/sync retry decorators - Add timeout protection decorator --- .env.development | 26 + .env.production | 28 + .github/workflows/test.yml | 55 ++ .gitignore | 12 + .gitlab-ci.yml | 21 + CHANGELOG.md | 45 +- CONTRIBUTING.md | 107 ++++ IMPROVEMENT_PLAN.md | 119 +++++ SECURITY.md | 69 +++ aiops/agents/__init__.py | 2 + aiops/agents/base_agent.py | 1 + aiops/agents/prompt_generator.py | 80 +++ aiops/api/error_responses.py | 129 +++++ aiops/api/main.py | 9 +- aiops/api/middleware.py | 8 +- aiops/core/config_validator.py | 70 +++ aiops/core/retry_utils.py | 129 +++++ aiops/core/token_tracker.py | 55 +- aiops/examples/15_webhook_integration.py | 9 +- aiops/examples/full_project_integration.py | 6 +- aiops/tests/test_base_agent.py | 484 ++++++++++++++++++ docker-compose.yml | 14 +- monitoring/alertmanager/alertmanager.yml | 42 ++ monitoring/prometheus/alerts/aiops-alerts.yml | 95 ++++ requirements.txt | 25 +- test_new_features.py | 5 +- 26 files changed, 1576 insertions(+), 69 deletions(-) create mode 100644 .env.development create mode 100644 .env.production create mode 100644 .github/workflows/test.yml create mode 100644 CONTRIBUTING.md create mode 100644 IMPROVEMENT_PLAN.md create mode 100644 SECURITY.md create mode 100644 aiops/agents/prompt_generator.py create mode 100644 aiops/api/error_responses.py create mode 100644 aiops/core/config_validator.py create mode 100644 aiops/core/retry_utils.py create mode 100644 aiops/tests/test_base_agent.py create mode 100644 monitoring/alertmanager/alertmanager.yml create mode 100644 monitoring/prometheus/alerts/aiops-alerts.yml diff --git a/.env.development b/.env.development new file mode 100644 index 0000000..2fad79d --- /dev/null +++ b/.env.development @@ -0,0 +1,26 @@ +# Development Environment Configuration +ENVIRONMENT=development +DEBUG=true +LOG_LEVEL=DEBUG + +# Database +DATABASE_URL=postgresql://aiops:dev_password@localhost:5432/aiops_dev + +# Redis +REDIS_URL=redis://localhost:6379/0 + +# API +API_HOST=0.0.0.0 +API_PORT=8000 +ENABLE_AUTH=false +ENABLE_RATE_LIMIT=false + +# CORS (permissive for development) +CORS_ORIGINS=http://localhost:3000,http://localhost:8080 + +# LLM (use test keys or mock in development) +# OPENAI_API_KEY=your-dev-key + +# Monitoring +ENABLE_METRICS=true +ENABLE_TRACING=false diff --git a/.env.production b/.env.production new file mode 100644 index 0000000..4624dae --- /dev/null +++ b/.env.production @@ -0,0 +1,28 @@ +# Production Environment Configuration +ENVIRONMENT=production +DEBUG=false +LOG_LEVEL=WARNING + +# Database (use environment variables, not hardcoded) +DATABASE_URL=${DATABASE_URL} + +# Redis +REDIS_URL=${REDIS_URL} + +# API +API_HOST=0.0.0.0 +API_PORT=8000 +ENABLE_AUTH=true +ENABLE_RATE_LIMIT=true + +# CORS (restrict to your domains) +CORS_ORIGINS=${CORS_ALLOWED_ORIGINS} + +# LLM +OPENAI_API_KEY=${OPENAI_API_KEY} +ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY} + +# Monitoring +ENABLE_METRICS=true +ENABLE_TRACING=true +SENTRY_DSN=${SENTRY_DSN} diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml new file mode 100644 index 0000000..56c0347 --- /dev/null +++ b/.github/workflows/test.yml @@ -0,0 +1,55 @@ +name: Tests + +on: + push: + branches: [main, develop] + pull_request: + branches: [main, develop] + +jobs: + test: + runs-on: ubuntu-latest + + steps: + -
