Finance Skills is a collection of agent skills for financial analysis and trading, covering activities such as company valuation, earnings research, market analysis, and options calculations. It is for users who want coding agents to perform structured finance workflows, and the catalogue contains its skills, plugins, instructions, and MCP integration.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00161 | $0.01972 |
| Opus 5 | $0.00081 | $0.00986 |
| Sonnet 5 | $0.00032 | $0.00394 |
| Haiku 4.5 | $0.00016 | $0.00197 |
Grade A, and why
twitter-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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Twitter Skill (Read-Only)
Reads Twitter/X for financial research using opencli, a universal CLI tool that bridges web services to the terminal via browser session reuse.
This skill is read-only. It is designed for financial research: searching market discussions, reading analyst tweets, tracking sentiment, and monitoring financial news on Twitter/X. It does NOT support posting, liking, retweeting, replying, or any write operations.
Important: opencli reuses your existing Chrome login session — no API keys or cookie extraction needed. Just be logged into x.com in Chrome and have the Browser Bridge extension installed.
Step 1: Ensure opencli Is Installed and 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 the status above shows READY, skip to Step 2. If NOT_INSTALLED, install first:
# Install opencli globally
npm install -g @jackwener/opencli
If SETUP_NEEDED, guide the user through setup:
Setup
opencli requires Node.js >= 20 and a Chrome browser with the Browser Bridge extension:
- Install the Browser Bridge extension:
- Download the latest
opencli-extension-v{version}.zipfrom the GitHub Releases page - Unzip it, open
chrome://extensionsin Chrome, and enable Developer mode - Click Load unpacked and select the unzipped folder
- Download the latest
- Login to x.com in Chrome — opencli reuses your existing browser session
- Verify connectivity:
opencli doctor
This auto-starts the daemon, verifies the extension is connected, and checks session health.
Common setup issues
| Symptom | Fix |
|---|---|
Extension not connected |
Install Browser Bridge extension in Chrome and ensure it's enabled |
Daemon not running |
Run opencli doctor — it auto-starts the daemon |
No session for twitter.com |
Login to x.com in Chrome, then retry |
CSRF token missing |
Refresh x.com in Chrome to regenerate the ct0 cookie |
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.
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.
