Dana: The Agent-Native Programming Language

Beyond AI coding assistants: write agents that learn, adapt, and improve themselves in production

---

What if your agents could learn, adapt, and improve itself in production—without you?

AI coding assistants help write better code. Agentic AI systems execute tasks autonomously. Dana represents the convergence: agent-native programming where you write agent instead of class, use context-aware reason() calls that intelligently adapt their output types, compose self-improving pipelines with | operators, and deploy functions that learn from production through POET.

TL;DR - Get Running in 30 Seconds! 🚀

pip install dana
# If you see an 'externally-managed-environment' error on macOS/Homebrew Python, use:
# pip install dana --break-system-packages
# Or use a virtual environment:
# python3 -m venv venv && source venv/bin/activate && pip install dana
dana start

No repo clone required. This launches the Dana REPL instantly.

Why Dana?

Dana transforms AI development from brittle, unpredictable systems to reliable, auditable automations through agent-native architecture:

• 🤖 Agent-Native: Purpose-built for multi-agent systems with first-class agent primitives
• 🛡️ Reliable: Built-in verification and error correction with structured state management
• ⚡ Fast: 10x faster development cycles with clear control flow
• 🧠 Context-Aware: reason() calls that adapt output types automatically based on usage
• 🔄 Self-Improving: Functions that learn and optimize through POET in production
• 🌐 Domain-Expert: Seamless integration of specialized knowledge and expertise
• 🔍 Transparent: Every step is visible and debuggable through imperative programming
• 🤝 Collaborative: Share and reuse working solutions across domains

Core Innovation: Agent-Native Programming

Dana provides an agent-native imperative programming model that bridges development assistance with autonomous execution:

# Traditional AI: Opaque, brittle
result = llm_call("analyze data", context=data)

# Dana: Transparent, self-correcting with explicit state management
analysis = reason("analyze data", context=data)  # Auto-scoped to local (preferred)
while confidence(analysis) < high_confidence:
    analysis = reason("refine analysis", context=[data, analysis])

# Clear state transitions and auditable reasoning
public:result = analysis
use("tools.report.generate", input=public:result)

Agent-Native Programming: Write agents as first-class primitives:

agent FinancialAnalyst:
    def assess_portfolio(self, data):
        return reason("analyze risk factors", context=data)  # Function learns over time

Context-Aware Intelligence: Same reasoning, different output types based on usage:

risk_score: float = reason("assess portfolio risk", context=portfolio)
risk_details: dict = reason("assess portfolio risk", context=portfolio)
risk_report: str = reason("assess portfolio risk", context=portfolio)

Self-Improving Pipelines: Compositional operations that optimize themselves:

portfolio | risk_assessment | recommendation_engine | reporting  # Gets smarter via POET
