opencli-rs Web Scraper & Site Fetcher

Skill by ara.so — Daily 2026 Skills collection.

opencli-rs is a single 4.7MB Rust binary that fetches real-time data from 55+ websites (Twitter/X, Reddit, YouTube, HackerNews, Bilibili, Zhihu, Xiaohongshu, and more) with one command. It reuses your browser session via a Chrome extension, supports AI-native API discovery, controls Electron desktop apps (Cursor, ChatGPT, Notion), and passes through to external CLIs (gh, docker, kubectl). Up to 12x faster and 10x less memory than the Node.js original.

Output Formats

opencli-rs hackernews top --limit 5 --format json | jq '.[].title'

# YAML
opencli-rs hackernews top --format yaml

# CSV — for spreadsheets
opencli-rs hackernews top --format csv > hn_top.csv

# Markdown — for docs
opencli-rs hackernews top --format markdown

---

Declarative YAML Pipeline (Custom Adapters)

Add new site adapters without writing Rust code. Create a YAML file describing the scraping pipeline:

# ~/.config/opencli-rs/adapters/my-site.yaml
name: my-site
description: Fetch top posts from my-site
base_url: https://api.my-site.com
commands:
  top:
    description: Get top posts
    endpoint: /v1/posts/top
    method: GET
    params:
      limit:
        flag: --limit
        default: 10
        query_param: count
    response:
      items_path: $.data.posts
      fields:
        - name: title
          path: $.title
        - name: url
          path: $.url
        - name: score
          path: $.points
        - name: author
          path: $.author.name

# Use the custom adapter
opencli-rs my-site top --limit 20
opencli-rs my-site top --format json

---

Real-World Patterns

Pipe JSON output to jq for filtering

# Get only titles from HN top stories
opencli-rs hackernews top --limit 20 --format json | jq -r '.[].title'

# Get Twitter trending topics as plain list
opencli-rs twitter trending --format json | jq -r '.[].name'

# Find Bilibili videos with >1M views
opencli-rs bilibili ranking --format json | jq '[.[] | select(.view > 1000000)]'

Shell scripting

#!/bin/bash
# Daily digest script

echo "=== HackerNews Top 5 ==="
opencli-rs hackernews top --limit 5 --format table

echo ""
echo "=== Bilibili Trending ==="
opencli-rs bilibili hot --limit 5 --format table

echo ""
echo "=== Zhihu Hot ==="
opencli-rs zhihu hot --limit 5 --format table

Export to file

opencli-rs reddit popular --format csv > reddit_$(date +%Y%m%d).csv
opencli-rs hackernews top --format json > hn_top.json

Use in Rust project via subprocess

use std::process::Command;
use serde_json::Value;

fn fetch_hn_top(limit: u32) -> anyhow::Result<Vec<Value>> {
    let output = Command::new("opencli-rs")
        .args(["hackernews", "top", "--limit", &limit.to_string(), "--format", "json"])
        .output()?;

    let json: Vec<Value> = serde_json::from_slice(&output.stdout)?;
    Ok(json)
}

fn fetch_twitter_search(query: &str) -> anyhow::Result<Vec<Value>> {
    let output = Command::new("opencli-rs")
        .args(["twitter", "search", query, "--format", "json"])
        .output()?;

    if !output.status.success() {
        let err = String::from_utf8_lossy(&output.stderr);
        anyhow::bail!("opencli-rs error: {}", err);
    }

     : <Value> = serde_json::(&output.stdout)?;
    (json)
}


  ()  anyhow::<()> {
      = ()?;
       &stories {
        (, story[].().());
    }
    (())
}

AI Agent integration (AGENT.md / .cursorrules)

# AGENT.md

## Available Tools
Run `opencli-rs list` to discover all available commands.

### Web Data Fetching
- `opencli-rs hackernews top --format json` — HN top stories
- `opencli-rs twitter search "<query>" --format json` — Twitter search
- `opencli-rs arxiv search "<topic>" --format json` — Research papers
- `opencli-rs reddit subreddit <name> --format json` — Subreddit posts

### Local CLI Tools
- `opencli-rs gh <args>` — GitHub operations
- `opencli-rs docker <args>` — Docker operations
- `opencli-rs kubectl <args>` — Kubernetes operations

Register custom tools: `opencli-rs register mycli`

---

Configuration

Config file location

~/.config/opencli-rs/config.toml   # macOS / Linux
%APPDATA%\opencli-rs\config.toml   # Windows

Custom adapter directory

# ~/.config/opencli-rs/config.toml
adapter_dir = "~/.config/opencli-rs/adapters"
default_format = "table"
default_limit = 20

Register a custom external CLI

# Register your own CLI tool for passthrough
opencli-rs register mycli

# Now use it via opencli-rs
opencli-rs mycli --help
opencli-rs mycli some-command --flag value

---

Troubleshooting

Run diagnostics first

opencli-rs doctor

Chrome extension not connecting

# Check extension is loaded at chrome://extensions
# Verify Developer mode is ON
# Reload the extension after reinstalling opencli-rs
# Check daemon is running:
opencli-rs doctor

Browser command returns empty / auth error

• Open Chrome and ensure you are logged in to the target site
• The extension reuses your existing browser session — no tokens needed
• Try refreshing the target site tab, then retry the command

Binary not found after install

# Verify install location
which opencli-rs
ls /usr/local/bin/opencli-rs

# Add to PATH if missing
export PATH="/usr/local/bin:$PATH"
echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.zshrc

Build errors from source

# Ensure Rust toolchain is up to date
rustup update stable
rustup target add aarch64-apple-darwin   # macOS Apple Silicon
cargo build --release

Command slow or timing out

• Browser commands require Chrome + extension; without it they will hang
• Run opencli-rs doctor to verify extension connectivity
• Public commands (hackernews, arxiv, etc.) need no browser and run in ~1-2s

Windows path issues

# Verify binary location
Get-Command opencli-rs
# If not found, ensure the directory is in $env:PATH
$env:PATH += ";$env:LOCALAPPDATA\Microsoft\WindowsApps"
