  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)

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](https://github.com/jackwener/opencli) (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`:

```bash
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](https://github.com/jackwener/opencli/releases)
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:

```bash
# 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

| Toutiao | `toutiao` | `articles` |
| Government policy / law | `gov-policy`, `gov-law` | (see `--help`) |
| Web download / reader | `web` | `read`, `download` |

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

```bash
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

```bash
# 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:

```bash
# 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.
