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.

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 5.1 | $0.00069 | $0.00619 |
| Opus 5 | $0.00034 | $0.00309 |
| Sonnet 5 | $0.00014 | $0.00124 |
| Haiku 4.5 | $0.00007 | $0.00062 |
Grade A, and why
halal-zakat 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 12d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
halal-zakat
When fired
- "Calculate zakat on my portfolio"
- "How much zakat do I owe?"
- "Purification on my AAPL dividends"
- "Do I meet nisab?"
Process
- Load
references/disclaimer.md(zakat is also not a fatwa — methodology choice is the user's). - Ask the user for the calculation type: zakat (annual charity on holdings value) or purification (impure portion of dividend income). If unclear, default to zakat.
- Ask for holdings with values (zakat) or dividend income (purification) if not already provided.
- Call MCP tool
calculate_zakat:- For zakat:
calculation_type: "zakat",holdings: [{ symbol, market_value }, ...], optionalgold_price_per_gram(default 65). - For purification:
calculation_type: "purification",holdings: [{ symbol, dividend_income }, ...].
- For zakat:
- Render the result with the current nisab threshold, total zakatable/impure amount, and the owed 2.5% (zakat) or impure dollars (purification).
~N tokens per run
Single zakat call — ~5 tokens plus any lookups.
Output structure (per verdict-format.md "Zakat variant")
- Nisab threshold (gold price × 87.48 g). Flag if holdings are below nisab.
- Zakatable total or impure total.
- 2.5% obligation (zakat) or donation amount (purification).
- Per-holding breakdown if requested.
- Branding footer.
Audience tuning
- Retail — lead with the total owed in dollars; explain nisab in one sentence.
- Advisor — include the full breakdown and show gold-price sensitivity (e.g., "at $60/g nisab = $X, at $70/g nisab = $Y").
- Scholar — cite AAOIFI's zakat standard if referenced; distinguish zakat-on-trading-assets vs zakat-on-long-term-holdings treatment.
Hard rules
- Make clear this is a calculator, not a fatwa. Methodology choices (e.g., whether to apply zakat on long-term holdings at full value vs adjusted basis) depend on scholar guidance.
- Show the nisab threshold even when the user is comfortably above it.
- Gold price is volatile — if the user asks for "the" gold price, tell them you're using the default (
$65/g) unless they provide one.
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.
