+# Novita CLI
+
+A CLI harness for **Novita AI** - an OpenAI-compatible API service for AI models like DeepSeek, GLM, and others.
+
+## Prerequisites
+
+- Python 3.10+
+- `requests` (HTTP client)
+- `click` (CLI framework)
+- Novita API key
+
+Optional (for interactive REPL):
+- `prompt_toolkit`
+
+## Install Dependencies
+
+```bash
+pip install requests click prompt_toolkit
+```
+
+## Get an API Key
+
+1. Go to [novita.ai](https://novita.ai) and sign up
+2. Navigate to Settings → API Keys
+3. Create an API key (format: `sk-xxx`)
+4. Configure it:
+
+```bash
+# Option 1: Config file (recommended)
+cli-anything-novita config set api_key "sk-xxx"
+
+# Option 2: Environment variable
+export NOVITA_API_KEY="sk-xxx"
+```
+
+## How to Run
+
+All commands are run from the `agent-harness/` directory or via the installed command.
+
+### One-shot Commands
+
+```bash
+# Show help
+cli-anything-novita --help
+
+# Chat with model
+cli-anything-novita chat --prompt "What is AI?" --model deepseek/deepseek-v3.2
+
+# Streaming chat
+cli-anything-novita stream --prompt "Write a poem about code"
+
+# Test connectivity
+cli-anything-novita test --model deepseek/deepseek-v3.2
+
+# List available models
+cli-anything-novita models
+
+# JSON output for agent consumption
+cli-anything-novita --json chat --prompt "Hello" --model deepseek/deepseek-v3.2
+```
+
+### Interactive REPL
+
+```bash
+cli-anything-novita
+```
+
+Inside the REPL, type `help` for all available commands.
+
+## Command Reference
+
+### Chat
+
+```bash
+chat --prompt <text> [--model <id>] [--temperature <0.0-1.0>] [--max-tokens <n>]
+stream --prompt <text> [--model <id>] [--temperature <0.0-1.0>] [--max-tokens <n>]
+```
+
+### Session
+
+```bash
+session status
+session clear
+session history [--limit N]
+```
+
+### Config
+
+```bash
+config set api_key "sk-xxx"
+config set default_model "deepseek/deepseek-v3.2"
+config get [key]
+config delete <key>
+config path
+```
+
+### Utility
+
+```bash
+test [--model <id>]  # Test API connectivity
+models              # List available models
+```
+
+## JSON Mode
+
+Add `--json` before the subcommand for machine-readable output:
+
+```bash
+cli-anything-novita --json chat --prompt "Hello"
+cli-anything-novita --json session status
+```
+
+## Default Models
+
+The CLI supports multiple models with `/` separator (not `-`):
+
+- `deepseek/deepseek-v3.2` (default)
+- `zai-org/glm-5`
+- `minimax/minimax-m2.5`
+
+## Running Tests
+
+```bash
+cd agent-harness
+
+# Unit tests (mock HTTP, no API key needed)
+python3 -m pytest cli_anything/novita/tests/test_core.py -v
+
+# E2E tests (requires NOVITA_API_KEY)
+NOVITA_API_KEY=sk-xxx python3 -m pytest cli_anything/novita/tests/test_full_e2e.py -v
+
+# All tests
+python3 -m pytest cli_anything/novita/tests/ -v
+```
+
+## Example Workflow
+
+```bash
+# Configure API key
+cli-anything-novita config set api_key "sk-xxx"
+
+# Chat with DeepSeek model
+cli-anything-novita chat --prompt "Explain quantum computing" --model deepseek/deepseek-v3.2
+
+# Stream response
+cli-anything-novita stream --prompt "Write a Python function to calculate factorial"
+
+# Test connectivity
+cli-anything-novita test --model deepseek/deepseek-v3.2
+
+# List available models
+cli-anything-novita models
+```
+
+## Supported Models
+
+| Model ID | Provider | Description |
+|----------|----------|-------------|
+| `deepseek/deepseek-v3.2` | DeepSeek | DeepSeek V3.2 model |
+| `zai-org/glm-5` | Zhipu AI | GLM-5 model |
+| `minimax/minimax-m2.5` | MiniMax | MiniMax M2.5 model |

+  Command-line interface for Novita AI - An OpenAI-compatible AI API client for DeepSeek, GLM, and other models.
+---
+
+# cli-anything-novita
+
+A CLI harness for **Novita AI** - an OpenAI-compatible API service for AI models like DeepSeek, GLM, and others.
+
+## Installation
+
+This CLI is installed as part of the cli-anything-novita package:
+
+```bash
+pip install cli-anything-novita
+```
+
+**Prerequisites:**
+- Python 3.10+
+- Novita API key from [novita.ai](https://novita.ai)
+
+## Usage
+
+### Basic Commands
+
+```bash
+# Show help
+cli-anything-novita --help
+
+# Start interactive REPL mode
+cli-anything-novita
+
+# Chat with model
+cli-anything-novita chat --prompt "What is AI?" --model deepseek/deepseek-v3.2
+
+# Streaming chat
+cli-anything-novita stream --prompt "Write a poem about code"
+
+# List available models
+cli-anything-novita models
+
+# JSON output (for agent consumption)
+cli-anything-novita --json chat --prompt "Hello"
+```
+
+### REPL Mode
+
+When invoked without a subcommand, the CLI enters an interactive REPL session:
+
+```bash
+cli-anything-novita
+# Enter commands interactively with tab-completion and history
+```
+
+## Command Groups
+
+### Chat
+
+Chat with AI models through the Novita API.
+
+| Command | Description |
+|---------|-------------|
+| `chat` | Chat with the Novita API |
+| `stream` | Stream chat completion |
+
+### Session
+
+Session management for chat history.
+
+| Command | Description |
+|---------|-------------|
+| `status` | Show session status |
+| `clear` | Clear session history |
+| `history` | Show command history |
+
+### Config
+
+Configuration management.
+
+| Command | Description |
+|---------|-------------|
+| `set` | Set a configuration value |
+| `get` | Get a configuration value (or show all) |
+| `delete` | Delete a configuration value |
+| `path` | Show the config file path |
+
+### Utility
+
+| Command | Description |
+|---------|-------------|
+| `test` | Test API connectivity |
+| `models` | List available models |
+
+## Examples
+
+### Configure API Key
+
+```bash
+# Set API key via config file (recommended)
+cli-anything-novita config set api_key "sk-xxx"
+
+# Or use environment variable
+export NOVITA_API_KEY="sk-xxx"
+```
+
+### Chat with DeepSeek
+
+```bash
+# Simple chat
+cli-anything-novita chat --prompt "Explain quantum computing" --model deepseek/deepseek-v3.2
+
+# Streaming chat
+cli-anything-novita stream --prompt "Write a Python function to calculate factorial"
+```
+
+### Test Connectivity
+
+```bash
+# Verify API key and connectivity
+cli-anything-novita test --model deepseek/deepseek-v3.2
+
+# List all available models
+cli-anything-novita models
+```
+
+## Default Models
+
+The Novita API supports multiple model providers:
+
+| Model ID | Provider | Description |
+|----------|----------|-------------|
+| `deepseek/deepseek-v3.2` | DeepSeek | DeepSeek V3.2 model (default) |
+| `zai-org/glm-5` | Zhipu AI | GLM-5 model |
+| `minimax/minimax-m2.5` | MiniMax | MiniMax M2.5 model |
+
+## Output Formats
+
+All commands support dual output modes:
+
+- **Human-readable** (default): Tables, colors, formatted text
+- **Machine-readable** (`--json` flag): Structured JSON for agent consumption
+
+```bash
+# Human output
+cli-anything-novita chat --prompt "Hello"
+
+# JSON output for agents
+cli-anything-novita --json chat --prompt "Hello"
+```
+
+## For AI Agents
+
+When using this CLI programmatically:
+
+1. **Always use `--json` flag** for parseable output
+2. **Check return codes** - 0 for success, non-zero for errors
+3. **Parse stderr** for error messages on failure
+4. **Use absolute paths** for all file operations
+5. **Verify outputs exist** after export operations
+
+## More Information
+
+- Full documentation: See README.md in the package
+- Test coverage: See TEST.md in the package
+- Methodology: See HARNESS.md in the cli-anything-plugin
