**OpenCLI leverages your existing Chrome login session to provide a unified, authentication-free backend for Twitter/X, Reddit, and XiaoHongShu, with Agent Reach automatically probing the daemon and extension status via `opencli_status` to prioritize it over other channel backends.**

Agent Reach (Panniantong/Agent-Reach) treats OpenCLI (`@jackwener/opencli`) as a desktop-only backend that reuses your existing Chrome cookies, eliminating per-platform credential configuration. The repository implements a sophisticated probing system across three channel implementations to detect OpenCLI availability and health before executing queries.

## How Agent Reach Probes OpenCLI Status

The `opencli_status` function in [`agent_reach/backends/opencli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/backends/opencli.py) performs non-destructive detection of the OpenCLI installation, daemon state, and Chrome extension connectivity.

### The Detection Pipeline

The probing mechanism executes in three stages. First, it runs `opencli --version` to verify the binary exists via the `probe_command` helper. Second, it executes `opencli daemon status` and parses the output for `Daemon: …` and `Extension: …` status lines. Third, if the extension reports as disconnected, a secondary disk check (`_extension_installed_on_disk`) searches typical Chrome profile roots:

- **macOS**: `~/Library/Application Support/Google/Chrome`
- **Linux**: `~/.config/google-chrome`
- **Windows**: `%LOCALAPPDATA%`

### The OpenCLIStatus Dataclass

The probe returns an `OpenCLIStatus` dataclass (lines 80-104) containing fields for `installed`, `broken`, `daemon_running`, `extension_connected`, `extension_installed`, `version`, and `hint`. This structured result enables channel-level logic to determine whether OpenCLI is ready for operations or requires user intervention.

## Channel-Level OpenCLI Integration

Each platform channel implements a private `_check_opencli()` method that interprets the `OpenCLIStatus` and returns standardized tuples for the public `check()` method.

### Twitter/X Channel Implementation

In [`agent_reach/channels/twitter.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/channels/twitter.py) (lines 94-108), the `_check_opencli()` method:

1. Imports and calls `opencli_status()` from `agent_reach.backends`
2. Returns `None` if OpenCLI is not installed, allowing fallback to `twitter-cli` or legacy backends
3. Returns `("error", hint)` if the binary exists but reports a broken state
4. Returns `("ok", message)` when `status.ready` is true (extension connected or sleeping)
5. Returns `("warn", hint)` when installed but the extension is disconnected, prompting the user to start Chrome

### Reddit and XiaoHongShu Implementations

The identical pattern appears in [`agent_reach/channels/reddit.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/channels/reddit.py) (lines 80-95) and [`agent_reach/channels/xiaohongshu.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/channels/xiaohongshu.py) (lines 97-112). Each probes OpenCLI before falling back to platform-specific alternatives like `reddit-cli` or manual cookie-based authentication.

### Backend Priority Logic

The public `check()` method in each channel iterates over `ordered_backends()`, where OpenCLI appears first in the list (e.g., `["OpenCLI", "twitter-cli", "bird CLI (legacy)"]` for Twitter). The selection algorithm prioritizes the first backend returning `("ok", ...)`, then falls back to the first `("warn", ...)`, ensuring OpenCLI wins over installed-but-unauthenticated alternatives.

## Installation and Setup Workflow

The CLI entry point in [`agent_reach/cli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/cli.py) provides automated installation guidance through `_install_opencli_deps()` (lines 742-754).

### Installing OpenCLI Dependencies

Running `python -m agent_reach.cli install --channels opencli` triggers the following workflow:

```bash

# Install the OpenCLI npm package globally

npm install -g @jackwener/opencli

# Install the Chrome extension from the Web Store

open https://chromewebstore.google.com/detail/opencli/ildkmabpimmkaediidaifkhjpohdnifk

```

### Verifying Daemon and Extension Status

After installation, verify the stack is operational:

```bash

# Check daemon and extension status

opencli daemon status

# Auto-start daemon and wake extension if needed

opencli doctor

```

The `opencli_status` probe interprets "Extension: connected" or sleeping-but-installed states as ready for use, while disconnected extensions trigger the `hint` field to guide users through Chrome extension activation.

## Cross-Platform Query Patterns

OpenCLI executes requests inside your logged-in Chrome instance, requiring no additional authentication configuration. Each platform follows a consistent YAML-formatted output pattern.

### Twitter/X Search Commands

Query tweets, articles, or user timelines:

```bash

# Search tweets

opencli twitter search "OpenAI GPT-4" -f yaml

# Fetch user posts

opencli twitter user-posts jack -f yaml

# Read specific article

opencli twitter article <url> -f yaml

```

### Reddit Search Commands

Perform subreddit searches and hot listing fetches:

```bash

# Search posts

opencli reddit search "machine learning" -f yaml

# Fetch hot posts from a subreddit

opencli reddit subreddit python hot -f yaml

# Read specific post

opencli reddit read <post_id> -f yaml

```

### XiaoHongShu Search Commands

Search notes and fetch user feeds:

```bash

# Search notes (Chinese keywords supported)

opencli xiaohongshu search "旅行" -f yaml

# Fetch note comments

opencli xiaohongshu comments <note_id> -f yaml

# Get user feed

opencli xiaohongshu feed <user_id> -f yaml

```

## Summary

- **OpenCLI** provides a unified backend for Twitter/X, Reddit, and XiaoHongShu by executing queries within your existing Chrome session.
- The **`opencli_status`** function in [`agent_reach/backends/opencli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/backends/opencli.py) probes installation, daemon state, and extension connectivity without side effects.
- Each channel's **`_check_opencli()`** method (in [`twitter.py`](https://github.com/Panniantong/Agent-Reach/blob/main/twitter.py), [`reddit.py`](https://github.com/Panniantong/Agent-Reach/blob/main/reddit.py), and [`xiaohongshu.py`](https://github.com/Panniantong/Agent-Reach/blob/main/xiaohongshu.py)) standardizes OpenCLI detection and returns `ok`, `warn`, `error`, or `None` statuses.
- OpenCLI appears **first** in `ordered_backends()`, giving it priority over other authentication methods when the Chrome extension is installed.
- All platforms use consistent **YAML-formatted output** via the `-f yaml` flag, enabling predictable parsing across Twitter searches, Reddit subreddits, and XiaoHongShu notes.

## Frequently Asked Questions

### How does OpenCLI authenticate with Twitter, Reddit, and XiaoHongShu without API keys?

OpenCLI operates as a Chrome extension that executes commands inside your existing browser session. Because it reuses your logged-in Chrome cookies and session storage, it requires no API keys, OAuth tokens, or manual credential entry. The extension simply automates the browser you already use for these platforms.

### What should I do if Agent Reach reports OpenCLI as installed but the extension is disconnected?

Run `opencli doctor` in your terminal to auto-start the daemon and wake the extension. If the issue persists, manually open Chrome and ensure the OpenCLI extension icon shows as connected. The `_check_opencli()` method in each channel returns a `("warn", hint)` tuple specifically for this scenario, guiding you to activate the extension before queries will succeed.

### Can I use OpenCLI on headless servers or CI/CD environments?

No. According to the source code in [`agent_reach/backends/opencli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/backends/opencli.py), OpenCLI is designed as a **desktop-only** backend that requires a local Chrome installation with the extension loaded. The probe checks for Chrome profile directories on macOS, Linux, and Windows, making it unsuitable for headless environments without a graphical browser session.

### How does Agent Reach choose between OpenCLI and other backends like twitter-cli?

The `check()` method in each channel file iterates through `ordered_backends()` and selects the first candidate returning an `("ok", ...)` status. Because OpenCLI appears first in the list, it wins whenever the binary is present and the extension is either connected or installed (even if sleeping). Only if OpenCLI returns `None` (not installed) or `("error", ...)` does Agent Reach fall back to `twitter-cli` or other alternatives.
