+
+## The Problem
+
+Existing observability tools show you _what_ LLM calls were made. AgentLens shows you _why_ your agent made each decision along the way -- which tool it picked, what alternatives it rejected, and the reasoning behind every choice.
+
+## Quick Start
+
+```bash
+pip install vectry-agentlens
+```
+
+```python
+import agentlens
+
+agentlens.init(api_key="your-key", endpoint="https://agentlens.vectry.tech")
+
+with agentlens.trace("my-agent-task", tags=["production"]):
+    # Your agent logic here...
+    agentlens.log_decision(
+        type="TOOL_SELECTION",
+        chosen={"name": "search_web", "confidence": 0.92},
+        alternatives=[{"name": "search_docs", "reason_rejected": "query too broad"}],
+        reasoning="User query requires real-time data not in local docs"
+    )
+
+agentlens.shutdown()
+```
+
+Open `https://agentlens.vectry.tech/dashboard` to see your traces.
+
+## Features
+
+- **Decision Tracing** -- Log every decision point with reasoning, alternatives, and confidence scores
+- **OpenAI Integration** -- Auto-instrument OpenAI calls with one line: `wrap_openai(client)`
+- **LangChain Integration** -- Drop-in callback handler for LangChain agents
+- **Nested Traces** -- Multi-agent workflows with parent-child span relationships
+- **Real-time Dashboard** -- SSE-powered live trace streaming with filtering and search
+- **Decision Tree Viz** -- Interactive React Flow visualization of agent decision paths
+- **Analytics** -- Token usage, cost tracking, duration timelines per trace
+- **Self-Hostable** -- Docker Compose deployment, bring your own Postgres + Redis
+
+## Architecture
+
+```
+SDK (Python)                 API (Next.js)              Dashboard (React)
+ agentlens.trace() ------>  POST /api/traces  ------>  Real-time SSE stream
+ agentlens.log_decision()   Prisma + Postgres          Decision tree viz
+ wrap_openai(client)        Redis pub/sub              Analytics & filters
+```
+
+## Integrations
+
+### OpenAI
+
+```python
+import openai
+from agentlens.integrations.openai import wrap_openai
+
+client = openai.OpenAI()
+wrap_openai(client)  # Auto-traces all completions
+
+with agentlens.trace("openai-task"):
+    response = client.chat.completions.create(
+        model="gpt-4o",
+        messages=[{"role": "user", "content": "Hello!"}]
+    )
+```
+
+### LangChain
+
+```python
+from agentlens.integrations.langchain import AgentLensCallbackHandler
+
+handler = AgentLensCallbackHandler()
+agent.run("Do something", callbacks=[handler])
+```
+
+### Custom Agents
+
+```python
+with agentlens.trace("planner"):
+    agentlens.log_decision(
+        type="ROUTING",
+        chosen={"name": "research_agent"},
+        alternatives=[{"name": "writer_agent"}],
+        reasoning="Task requires data gathering first"
+    )
+    with agentlens.trace("researcher"):
+        # Nested trace creates child span automatically
+        agentlens.log_decision(
+            type="TOOL_SELECTION",
+            chosen={"name": "web_search"},
+            alternatives=[{"name": "database_query"}],
+            reasoning="Need real-time information"
+        )
+```
+
+## Decision Types
+
+| Type | Use Case |
+|------|----------|
+| `TOOL_SELECTION` | Agent chose which tool/function to call |
+| `ROUTING` | Agent decided which sub-agent or path to take |
+| `PLANNING` | Agent formulated a multi-step plan |
+| `RETRY` | Agent decided to retry a failed operation |
+| `ESCALATION` | Agent escalated to human or higher-level agent |
+| `MEMORY_RETRIEVAL` | Agent chose what context to retrieve |
+| `CUSTOM` | Any other decision type |
+
+## Self-Hosting
+
+```bash
+git clone https://gitea.repi.fun/repi/agentlens.git
+cd agentlens
+docker compose up -d
+```
+
+The dashboard will be available at `http://localhost:4200`.
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `DATABASE_URL` | `postgresql://agentlens:agentlens@postgres:5432/agentlens` | PostgreSQL connection string |
+| `REDIS_URL` | `redis://redis:6379` | Redis connection string |
+| `NODE_ENV` | `production` | Node environment |

+# AgentLens Examples
+
+Example scripts demonstrating the AgentLens SDK for tracing and observing AI agent behavior.
+
+## Setup
+
+```bash
+pip install vectry-agentlens
+```
+
+## Examples
+
+| Script | Description |
+|--------|-------------|
+| `basic_agent.py` | Simplest usage — init, trace, log decisions, shutdown |
+| `openai_agent.py` | OpenAI integration — wrap the client for automatic LLM call tracing |
+| `multi_agent.py` | Nested traces — planner delegates to researcher, writer, and editor sub-agents |
+| `customer_support_agent.py` | Realistic support workflow — classification, routing, escalation, error handling |
+| `seed_demo_traces.py` | Seeds the live dashboard with 11 realistic traces via direct HTTP POST (no SDK) |
+
+## Running
+
+Each SDK example follows the same pattern:
+
+```bash
+# Set your API key and endpoint
+export AGENTLENS_API_KEY="your-key"
+
+# Run any example
+python examples/basic_agent.py
+```
+
+For the OpenAI example, you also need:
+
+```bash
+pip install openai
+export OPENAI_API_KEY="sk-..."
+```
+
+### Seed Script
+
+The seed script sends pre-built traces directly to the API — no SDK or OpenAI key needed:
+
+```bash
+python examples/seed_demo_traces.py
+```
+
+This populates the dashboard with varied traces (COMPLETED, ERROR, RUNNING) across multiple agent types.
