opencli-reader

A read-only fallback for retrieving information from websites and services supported by opencli, a command-line tool with adapters for many sources. It is used when the project has no more specific reader for that source.

In plain words
What is it for?
Use it to read sources such as Yahoo Finance, Bloomberg, Reuters, Reddit, Hacker News, arXiv, Google Scholar, podcasts, and other services in opencli’s registry.
Why use it?
It gives an agent one general way to read from less commonly covered sources while preventing actions such as posting, liking, commenting, or subscribing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

opencli-reader scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 262 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 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 UIPUBLIC 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

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
