+# 🪐 Agent Loop
+
+An autonomous reasoning and multi-strategy execution orchestrator built for Docker on Hugging Face Spaces.
+
+## 🚀 Features
+
+- **Multi-Strategy Agent Loops**:
+  - **ReAct**: Interleaved reasoning and action loops with real-time environment observations.
+  - **Plan-and-Solve**: Hierarchical goal decomposition into sequential milestone tasks.
+  - **Reflexion**: Self-critique, evaluation metrics, and reflective refinement steps.
+  - **Autonomous Explorer**: Dynamic environment exploration and volume report synthesis.
+- **Persistent Storage Integration**:
+  - Automatically binds to the Hugging Face Space persistent storage volume mounted at `/data`.
+  - Archival of all execution traces in `/data/runs/`.
+  - Artifact and deliverable storage in `/data/artifacts/`.
+- **Real-Time Streaming UI**:
+  - Server-Sent Events (SSE) streaming direct to a sleek, dark-mode glassmorphism dashboard.
+  - Live execution phase indicators, progress meters, and real-time telemetry gauges (CPU, RAM, Disk).
+- **RESTful API & Swagger Docs**:
+  - Interactive OpenAPI documentation available at `/docs`.
+  - Programmatic endpoints for triggering agent loop runs and managing persistent files.
+
+## 🐳 Docker Setup
+
+The application runs inside a lightweight Docker container (`python:3.11-slim`) configured to comply with Hugging Face Space security requirements:
+- Exposes port `7860`.
+- Executes under non-root user `user` (`UID 1000`).
+- Persistent volume support at `/data`.
+
+## 📦 API Endpoints
+
+- `GET /` — Interactive web application.
+- `GET /docs` — Swagger / OpenAPI documentation.
+- `GET /api/health` — Service health status.
+- `GET /api/telemetry` — Live system and resource metrics.
+- `POST /api/loop/run` — Run an agent loop with real-time SSE streaming.
+- `GET /api/storage/files` — List files stored in persistent volume.
+- `GET /api/storage/file` — Read content of a stored artifact or run log.
