opencli Reader (Generic Fallback, Read-Only)

If your host has not already executed the shell probes below (for example, in Codex), run the commands inside the ! wrappers with its shell tool before choosing a setup path. Use the actual output; if shell access is unavailable, report that limitation.

Generic fallback for any source opencli supports via its adapter registry (100+ sites, growing). Use this skill only when no dedicated finance-skill covers the source — the specialized skills (twitter-reader, linkedin-reader, discord-reader, telegram-reader, yc-reader) are always preferred when the request matches one of them.

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 user asks about…	Use this skill instead
Twitter/X	twitter-reader
LinkedIn	linkedin-reader
Discord	discord-reader
Telegram	telegram-reader
Y Combinator	yc-reader
Anything else opencli supports (Yahoo Finance, Bloomberg, Reuters, Reddit, HackerNews, Eastmoney, Xueqiu, Substack, arXiv, etc.)	this 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):

1. Download the latest opencli-extension-v{version}.zip from the GitHub Releases page
2. Unzip it, open chrome://extensions in Chrome, enable Developer mode
3. Click Load unpacked and select the unzipped folder
4. 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.

For anything not listed, run opencli list -f json and filter.

Step 4: Check the Adapter's Strategy Before Running

Run opencli list -f json (or opencli <site> <command> --help) and read the strategy field:

Strategy	What it means	Preconditions
PUBLIC	Pure HTTP; no browser needed	None
LOCAL	Talks to a local endpoint	Local service running
COOKIE / HEADER	Reuses your Chrome login for the site	Chrome logged into the site + Browser Bridge extension loaded
INTERCEPT	Opens an automation window to capture a signed request	Same as COOKIE; be patient — may take several seconds
UI	Full DOM interaction	Same as COOKIE; slowest; results depend on the site's current layout

If the user doesn't have a login and the adapter's strategy is not PUBLIC / LOCAL, tell them they need to log into the site in Chrome before retrying.

---

Step 5: Execute the Command

General pattern

opencli <site> <command> [positional-args] [flags] -f json

Universal flags

Flag	Effect
-f json	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

1. Always use opencli <site> <command> --help before constructing a command you haven't run this session — don't assume flag names.
2. Use -f json for programmatic processing.
3. Start with a small --limit (10–20) to validate the shape before pulling more.
4. Check strategy before running a browser-backed adapter — if the user isn't logged in, a COOKIE / UI adapter will fail.
5. 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:

1. If the user has the opencli-autofix skill installed, tell them to run that skill.
2. If not, suggest they file an issue at https://github.com/jackwener/opencli/issues with the RepairContext output.
3. 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

1. Summarize the data for the user's actual question, don't just dump the raw JSON.
2. Include source attribution — site name + URL for each item where available.
3. For market data, surface price / % change / volume / market cap and flag anomalies.
4. For news/posts, highlight headlines, timestamps, and key quotes.
5. For research (arXiv, Scholar), include title, authors, abstract, and link.
6. Treat browser sessions as private — never echo CDP endpoints, cookies, or auth tokens.
