AGENTS.md Rules & Agent Skills
Django + PostgreSQL + Redis + Celery
Production guidelines for Django 5 enterprise applications, PostgreSQL connection pooling, Redis caching, and Celery async workers.
FastAPI + Python + PostgreSQL (Async SQLAlchemy & Pydantic v2)
Production guidelines for FastAPI, Pydantic v2 validation, Async SQLAlchemy 2.0 (asyncpg), Alembic migrations, and PostgreSQL/Redis.
LangGraph + Python + FastAPI (Agentic AI Workflows)
Production architecture for autonomous multi-agent systems, LangGraph cyclic state graphs, Pydantic v2 structured tool calling, and Chroma/Qdrant vector stores.
Production Projects
MindsDB
Connects enterprise databases directly to AI and machine learning models using standard SQL statements. Enables developers to query, train, and orchestrate generative AI agents and predictive models directly over PostgreSQL, Snowflake, and MongoDB data sources.
vLLM
The gold standard for production LLM inference; invented PagedAttention to eliminate memory fragmentation in GPU KV caches, delivering 2x-4x throughput over standard Hugging Face runtimes.
LangChain
Industry standard for context-aware reasoning; modular chains and LangGraph cyclic graphs allow orchestrating stateful agents with deterministic fallbacks and tool execution.
FastAPI
Benchmark for modern Python APIs and AI services; pairs Starlette with Pydantic v2 Rust core for ultra-high throughput and automatic interactive documentation.
GlitchTip
Lightweight Sentry-compatible application performance monitoring and error tracking platform. Built on Python Django and PostgreSQL with async Celery task queues for high-volume exception ingestion and Redis message buffering.
Open WebUI
Extensible OpenAI/Ollama interface; SvelteKit frontend delivers instant responsive streaming while Python FastAPI handles multi-modal RAG and tool calls.
Immich
High-performance Google Photos alternative; utilizes SvelteKit and NestJS with background Python workers for hardware-accelerated transcoding and facial recognition.
Mem0
Universal memory layer for AI agents; extracts and persists structured personal facts and episodic memories across user chat sessions with low latency.
Authentik
Enterprise open source IAM; Django core manages permission trees while lightweight Go outposts terminate TLS and validate tokens at the edge.
Taipy
Full-stack data science & AI framework; Python business logic binds directly to reactive React frontend components without frontend coding.
Baserow
Open source Airtable alternative; Django & FastAPI generate dynamic PostgreSQL table schemas per user workspace.
Sentry
Enterprise observability; Django handles transactional models while high-volume event ingestion is streamed via Kafka to ClickHouse.
Mage AI
Modern data orchestration tool; Python execution engine with interactive React notebook UI for building real-time data pipelines.
Dify.ai
High-throughput AI pipeline: visual canvas frontend with Python worker cluster for asynchronous LLM orchestration.
OpenBB
Dozens of data provider adapters: schema validation is a core product requirement.
