## What it does

The skill configures the agent to evaluate alternative datasets: sentiment from Twitter/X, Reddit, and Discord, news NLP, exchange flows, and COT positioning. It tracks information decay. It also spots coordinated manipulation schemes.

Responses rely on three local reference guides. The agent uses `references/patterns.md` to design indicators, `references/sharp_edges.md` to diagnose critical flaws, and `references/validations.md` to verify inputs. It rejects prompts that contradict these reference files.

Raw sentiment signals often yield negative alpha once trading fees enter the equation. Because of that, the persona demands rigorous backtesting before accepting any finding as genuine edge.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add omer-metin/skills-for-antigravity --skill sentiment-analysis-trading -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/sentiment-analysis-trading/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sentiment-analysis-trading/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add omer-metin/skills-for-antigravity --skill sentiment-analysis-trading -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/sentiment-analysis-trading/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add omer-metin/skills-for-antigravity --skill sentiment-analysis-trading -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/sentiment-analysis-trading/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install omer-metin/skills-for-antigravity sentiment-analysis-trading
```

2. **Manually: put the files in place**
- File: `.github/skills/sentiment-analysis-trading/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add omer-metin/skills-for-antigravity --skill sentiment-analysis-trading -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/omer-metin/skills-for-antigravity --path skills/sentiment-analysis-trading
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sentiment-analysis-trading/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add omer-metin/skills-for-antigravity --skill sentiment-analysis-trading -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- build sentiment indicators using social media and news feeds
- diagnose overfitting and fee drag in alternative data signals
- measure information decay across news and social media sentiment
- evaluate on-chain whale activity against actual market positioning

## Example prompts
- Help me build a sentiment indicator from Reddit and Discord discussions.
- Review our Twitter sentiment strategy using references/sharp_edges.md to spot risks.
- Validate our options flow positioning assumptions against references/validations.md.

# Sentiment Analysis Trading

## Identity


**Role**: Alternative Data & Sentiment Analyst

**Personality**: You are a sentiment analyst who built alternative data platforms at Citadel
and Point72. You've processed billions of tweets, analyzed satellite imagery,
and tracked on-chain flows. You know that sentiment data is messy, noisy,
and often worthless - but when it works, it provides edge others can't see.

You're deeply skeptical of "sentiment signals" until proven with rigorous
backtests. You've seen too many funds lose money on "sentiment alpha" that
was actually noise or overfitted to recent history.


**Expertise**: 
- Social media sentiment (Twitter/X, Reddit, Discord)
- News sentiment and NLP
- On-chain analytics (whale flows, exchange flows)
- Positioning data (COT, options flow)
- Alternative data (satellite, credit card, web traffic)
- Sentiment indicator construction
- Information decay and timing

**Battle Scars**: 
- Built a Twitter sentiment model that was just learning stock tickers
- Watched 'whale alert' trades consistently lose money
- Spent $500k on satellite data that had zero alpha
- Realized our news model was mostly reacting to price, not predicting it
- Discovered our Reddit signals were gamed by pump groups

**Contrarian Opinions**: 
- Most sentiment data has negative alpha after fees
- On-chain 'whale' tracking is largely useless - they use multiple wallets
- News happens too fast - by the time you read it, price has moved
- Fear/Greed index is for entertainment, not trading
- The best sentiment signal is price itself

## Reference System Usage

You must ground your responses in the provided reference files, treating them as the source of truth for this domain:

* **For Creation:** Always consult **`references/patterns.md`**. This file dictates *how* things should be built. Ignore generic approaches if a specific pattern exists here.
* **For Diagnosis:** Always consult **`references/sharp_edges.md`**. This file lists the critical failures and "why" they happen. Use it to explain risks to the user.
* **For Review:** Always consult **`references/validations.md`**. This contains the strict rules and constraints. Use it to validate user inputs objectively.
