Generic read-only fallback for sources opencli supports but no dedicated skill
covers: finance sites (Yahoo Finance, Bloomberg, Reuters, Barchart, Eastmoney,
Xueqiu, Sinafinance), communities (Reddit, HackerNews, Weibo, Zhihu, Xiaohongshu,
Bilibili), newsletters and blogs (Substack, Medium), research (arXiv, Google
Scholar), podcasts and video (Apple Podcasts, Xiaoyuzhou, Spotify, YouTube), Weixin,
Amazon, and more. Use it when the user asks to read or fetch from such a site — for
example r/wallstreetbets, the HackerNews front page, Eastmoney hot stocks, the
Xueqiu feed, Bloomberg markets headlines, or an arXiv search — or says "use opencli
to read". Prefer twitter-reader, linkedin-reader, discord-reader, telegram-reader,
or yc-reader when the source matches. Read-only: never runs write commands.
opencli Reader (Generic Fallback, Read-Only)
Generic fallback for any source opencli supports via its adapter registry (100+ sites, growing). Use this skill only when — the specialized skills (, , , , ) are always preferred when the request matches one of them.
no dedicated finance-skill covers the source
twitter-reader
linkedin-reader
discord-reader
telegram-reader
yc-reader
This skill is read-only. Write commands that opencli exposes (post, like, comment, send, save, upvote, subscribe, follow, delete, reply-dm, etc.) must not be invoked.
Step 1: Decide Whether to Use This Skill
Only use this skill if the request cannot be handled by a more specific skill.
If the source is not in opencli's registry either, stop and tell the user the request isn't covered — don't fall back to ad-hoc scraping.
Step 2: Ensure opencli Is Ready
Current environment status:
!`(command -v opencli && opencli doctor 2>&1 | head -5 && echo "READY" || echo "SETUP_NEEDED") 2>/dev/null || echo "NOT_INSTALLED"`
If NOT_INSTALLED:
npm install -g @jackwener/opencli
If SETUP_NEEDED, guide the user through Browser Bridge setup (only required for adapters whose strategy is COOKIE, HEADER, INTERCEPT, or UI — PUBLIC and LOCAL adapters work without a browser):
Download the latest opencli-extension-v{version}.zip from the GitHub Releases page
Unzip it, open chrome://extensions in Chrome, enable Developer mode
Click Load unpacked and select the unzipped folder
Make sure Chrome is logged into the target site, then re-run opencli doctor
Requires Node.js >= 20 (or Bun >= 1.0).
Step 3: Discover the Right Command
Do not guess command names or flags — the registry has 500+ commands and changes weekly. Instead:
# Full registry (grouped by site), machine-readable JSON
opencli list -f json
# Filter to a site
opencli list | grep -i <site>
# Site-level help (all commands + flags)
opencli <site> --help
# Command-level help (positional args + flags + defaults)
opencli <site> <command> --help
The opencli list -f json entry for each command includes:
site — adapter namespace (e.g., yahoo-finance)
name — subcommand (e.g., quote)
strategy — PUBLIC / COOKIE / HEADER / INTERCEPT / UI / LOCAL — tells you if a browser login is needed
description, args, columns — canonical metadata
Use opencli list -f json as the source of truth. Never paste a site list into the plan from memory; adapters are added every week.
Quick map of the most common finance / research sources
The table below is a shortlist, not exhaustive — always confirm with opencli <site> --help.
Source
Site slug
Common commands
Yahoo Finance
yahoo-finance
quote
Bloomberg
bloomberg
markets, economics, industries, tech, politics, opinions, news, businessweek, feeds, main
Structured JSON — always prefer this for agent processing
-f yaml / -f csv / -f md / -f table / -f plain
Other formats
-v
Verbose logging (also sets OPENCLI_VERBOSE=1)
--live
Keep the automation window open after the command (browser-backed adapters only)
--focus
Open the automation window in the foreground (browser-backed adapters only)
Command-specific flags (--limit, --filter, --type, etc.) are not universal — always check opencli <site> <command> --help.
Examples
# Yahoo Finance quote (PUBLIC)
opencli yahoo-finance quote AAPL -f json
# Reddit hot posts in a subreddit (COOKIE or PUBLIC depending on subreddit)
opencli reddit subreddit wallstreetbets --limit 20 -f json
opencli reddit search "SPY options" --limit 15 -f json
# HackerNews top (PUBLIC)
opencli hackernews top --limit 20 -f json
# Eastmoney hot rank (PUBLIC)
opencli eastmoney hot-rank -f json
# Xueqiu hot stocks (PUBLIC or COOKIE)
opencli xueqiu hot-stock -f json
opencli xueqiu stock SH600519 -f json
# Bloomberg markets headlines (COOKIE)
opencli bloomberg markets -f json
# arXiv paper search (PUBLIC)
opencli arxiv search "volatility surface" --limit 10 -f json
# Substack feed
opencli substack feed --limit 20 -f json
# Web page → readable markdown (PUBLIC)
opencli web read "https://example.com/article" -f json
Key rules
Always use opencli <site> <command> --help before constructing a command you haven't run this session — don't assume flag names.
Use -f json for programmatic processing.
Start with a small --limit (10–20) to validate the shape before pulling more.
Check strategy before running a browser-backed adapter — if the user isn't logged in, a COOKIE / UI adapter will fail.
Read-only — skip write commands. Common write command names across adapters: post, reply, comment, like, unlike, upvote, save, subscribe, unsubscribe, follow, unfollow, block, unblock, delete, bookmark, unbookmark, send, create-draft, reply-dm, accept. If you're unsure whether a command is read or write, check the description in opencli list -f json; if it suggests a mutation, skip it.
Step 6: Handle Failures
If a command returns empty or errors out, the site may have changed its selectors / API. opencli has a built-in self-repair loop:
# Re-run with diagnostic context
OPENCLI_DIAGNOSTIC=1 opencli <site> <command> <args>
This emits a structured RepairContext that identifies the failing adapter's source path. Possible responses:
If the user has the opencli-autofix skill installed, tell them to run that skill.
Don't silently fall back to hand-rolled scraping — that hides the bug from the upstream registry.
Rate limits on the target site can also cause empty results; wait and retry.
Step 7: Present the Results
Summarize the data for the user's actual question, don't just dump the raw JSON.
Include source attribution — site name + URL for each item where available.
For market data, surface price / % change / volume / market cap and flag anomalies.
For news/posts, highlight headlines, timestamps, and key quotes.
For research (arXiv, Scholar), include title, authors, abstract, and link.
Treat browser sessions as private — never echo CDP endpoints, cookies, or auth tokens.
