kite-agent 0.2.0

Production-Ready Agentic AI Framework with Enterprise Safety

🪁 Kite

From idea to running AI agent in one command.

pip install kite-agent
kite generate "customer support agent that tracks orders"

A running, multi-agent Python script. No boilerplate. No config files.

Why Kite?

LangChain gives you 500+ abstractions. AutoGen needs 100 lines of config.
Kite gives you one command — and a different philosophy.

	LangChain	AutoGen	Kite
Time to first agent	~30 min	~20 min	< 1 min
LLM as untrusted component	❌	❌	✅
Built-in circuit breaker	❌	❌	✅
Kill switch	❌	❌	✅
Prompt A/B testing	❌	❌	✅
CLI code generation	❌	❌	✅
Startup time	~2s	~1s	~50ms

---

The core idea: LLMs don't execute. They propose.

Most frameworks let the LLM call tools directly. Kite doesn't.

# ❌ Other frameworks: LLM decides what runs
agent.run("delete all test users")  # LLM calls delete_user() directly

# ✅ Kite: LLM proposes, Kernel validates
shell = ShellTool(allowed_commands=["ls", "git", "df"])
# agent.run("rm -rf /") → blocked at kernel, never executes

30-second quickstart

pip install kite-agent
export GROQ_API_KEY=your_key    # free at console.groq.com
kite generate "research assistant that searches and summarizes" --out agent.py
python agent.py

Or scaffold a full project:

kite init --type=agent --name=my_bot
cd my_bot && cp .env.example .env
python main.py

Production safety — built in, not bolted on

from kite import Kite

ai = Kite()

# Circuit breaker — auto-stops cascading failures
ai.circuit_breaker.config.failure_threshold = 3
ai.circuit_breaker.config.timeout_seconds = 60

# Idempotency — no duplicate charges, no double-sends
result = ai.idempotency.execute(
    operation_id="order_123_refund",   # same id = cached result
    func=process_refund,
    args=(order_id,)
)

# Kill switch — emergency stop, per-agent or global
ai.kill_switch.activate("Budget limit reached")
agent.kill_switch.activate("This agent only")

---

5 reasoning patterns

agent = ai.create_agent(name="Bot", agent_type="react", ...)        # think→act→observe loop
agent = ai.create_agent(name="Bot", agent_type="rewoo", ...)        # plan upfront, run parallel (~2× faster)
agent = ai.create_agent(name="Bot", agent_type="tot", ...)          # explore multiple paths
agent = ai.create_agent(name="Bot", agent_type="plan_execute", ...) # decompose, replan on failure
agent = ai.create_agent(name="Bot", agent_type="reflective", ...)   # generate → critique → improve

---

Advanced RAG — production retrieval, not toy examples

# Load any document type
ai.load_document("docs/policy.pdf")   # PDF, DOCX, CSV, HTML, TXT
ai.load_document("data/")             # entire directory

# HyDE — generate hypothetical answer first, then search (↑ accuracy)
results = ai.advanced_rag.search("return policy", method="hyde")

# Hybrid search — BM25 keyword + vector semantic combined
results = ai.advanced_rag.hybrid_search("cancellation steps", alpha=0.5)

# MMR — remove redundant results, maximize diversity
results = ai.advanced_rag.mmr("pricing tiers", results, lambda_param=0.7)

# Reranking — Cohere or Cross-encoder for final precision
results = ai.advanced_rag.rerank_cohere("refund eligibility", results)

# Knowledge graph — multi-hop relationship queries
ai.graph_rag.add_relationship("Order", "belongs_to", "Customer")
answer = ai.graph_rag.query("Which orders belong to premium customers?")

---

Prompt A/B testing

Test prompts and models on real traffic. No other Python agent framework ships this.

from kite.ab_testing import ABTestManager

ab = ABTestManager()
ab.create_experiment(
    name="support_tone",
    variants=[
        {"name": "formal", "weight": 0.5, "config": {"system_prompt": "You are professional..."}},
        {"name": "casual", "weight": 0.5, "config": {"system_prompt": "Hey! Happy to help..."}},
    ]
)

variant = ab.get_variant("support_tone", user_id="user_123")  # consistent per user
ab.record_conversion("support_tone", variant.name)

results = ab.get_results("support_tone")
# → {"winner": "casual", "confidence": 0.94, "conversions": {...}}

---

Multi-agent conversation

researcher = ai.create_agent("Researcher", "You gather facts...",         agent_type="react")
critic     = ai.create_agent("Critic",     "You challenge assumptions...")
writer     = ai.create_agent("Writer",     "You synthesize into prose...")

conversation = ai.create_conversation(
    agents=[researcher, critic, writer],
    max_turns=9,
    termination_condition="consensus"
)

result = await conversation.run("Best pricing strategy for B2B SaaS?")

---

Smart model routing — cut costs 60–80%

# .env
FAST_LLM_MODEL=groq/llama-3.1-8b-instant   # routing, simple tasks
SMART_LLM_MODEL=openai/gpt-4o              # complex reasoning

from kite.optimization.resource_router import ResourceAwareRouter

router   = ResourceAwareRouter(ai.config)
router_a = ai.create_agent("Router",  model=router.fast_model,  ...)
analyst  = ai.create_agent("Analyst", model=router.smart_model, ...)

---

Human-in-the-loop workflows

pipeline = ai.pipeline.create("approval_flow")
pipeline.add_step("draft",  draft_email)
pipeline.add_checkpoint("draft")    # ← pauses for human review
pipeline.add_step("send",   send_email)

state = await pipeline.execute_async({"to": "[e-mail]"})
final = await pipeline.resume_async(state.task_id, approved=True)

---

Observability

ai.enable_tracing("run_trace.json")              # every event → JSON file
ai.enable_state_tracking("session.json")         # state changes across session
ai.event_bus.subscribe("agent:*", my_callback)   # subscribe to any event
ai.add_event_relay("http://localhost:8000/events") # forward to dashboard
print(ai.get_metrics())   # circuit breaker, cache hits, token usage

---

Works with any LLM

LLM_PROVIDER=groq       LLM_MODEL=llama-3.3-70b-versatile   # fastest, free tier
LLM_PROVIDER=openai     LLM_MODEL=gpt-4o                    # most capable
LLM_PROVIDER=anthropic  LLM_MODEL=claude-3-5-sonnet-...     # best reasoning
LLM_PROVIDER=ollama     LLM_MODEL=qwen2.5:1.5b              # local, free

Switch by changing 2 env vars. Zero code changes.
