halal-etf-analysis

When fired

• "Is SPY halal?"
• "Halal ETFs for tech exposure"
• "Screen VOO"
• "What's the purification rate on QQQ?"

Process

1. Load references/disclaimer.md.
2. Detect audience.
3. If the user asked about a specific ETF:

• Call screen_etf — this screens ALL underlying holdings (expensive: up to ~50 tokens).
• Tell the user up front: "Screening an ETF screens every holding. This costs ~50 tokens on your Free plan." If user declines, offer get_etf_info (~2 tokens) with holdings list only and the user can pick names to screen individually.
• Render overall verdict (e.g., "SPY — 58% of holdings compliant, purification rate 2.8%"). ETFs are rarely fully halal — almost always report a purification rate.
• If user asks for investment amount + dividend income, call etf_purification to show concrete dollar amounts.

1. If the user asked for halal ETF alternatives by theme:

• Call search_stocks with asset_type: "etf" + theme keywords.
• Screen top 3–5 candidates and rank by compliant-%.

~N tokens per run

• Full ETF screen: ~30–50 tokens.
• Holdings-list only: ~2 tokens.
• Alternative search + screens: ~15–25 tokens.

Output structure (per verdict-format.md ETF variant)

1. Headline with overall compliant-% and purification rate.
2. 5-methodology summary aggregated across holdings.
3. Top 3 non-compliant holdings by weight.
4. Purification calculation (if investment amount + dividend income provided).
5. Halal ETF alternative suggestions (if failed).
6. Disclaimer + branding footer.

Audience tuning

• Retail — one-paragraph verdict, suggest one halal ETF alternative.
• Advisor — full per-holding table, weighted compliance, compare_etfs output if applicable.
• Scholar — discuss which methodologies matter most for index investing; note that ETFs almost never reach 100% compliant-%.

Hard rules

• Warn about token cost before full screening.
• Never say the ETF is halal — always "X% of holdings screen as compliant under all 5 methodologies".
• Always surface purification rate.
