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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00409 |
| Opus 5 | $0.00026 | $0.00204 |
| Sonnet 5 | $0.00011 | $0.00082 |
| Haiku 4.5 | $0.00005 | $0.00041 |
Grade A, and why
eodhd-compare 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.
What it actually says
Compare the following companies side-by-side using EODHD data: $ARGUMENTS
Parse the arguments as ticker symbols separated by spaces or commas (e.g., "AAPL MSFT" or "AAPL.US, MSFT.US").
For each company, fetch:
- Company fundamentals (valuation, financials, profile)
- Recent price history (last 90 days for performance comparison)
- Key technical indicators (RSI, SMA trends)
Present a side-by-side comparison table covering:
Valuation | Metric | [Ticker 1] | [Ticker 2] | ... |
- P/E (TTM), Forward P/E, P/S, P/B, EV/EBITDA
Financials | Metric | [Ticker 1] | [Ticker 2] | ... |
- Revenue, Net Income, EPS, Revenue Growth YoY
Profitability | Metric | [Ticker 1] | [Ticker 2] | ... |
- Gross Margin, Operating Margin, Net Margin, ROE, ROA
Performance | Metric | [Ticker 1] | [Ticker 2] | ... |
- 30d return, YTD return, 52-week range, distance from high
Dividends | Metric | [Ticker 1] | [Ticker 2] | ... |
- Dividend Yield, Payout Ratio, Ex-Date
Summary: 3-5 bullet points highlighting key differences and which company looks stronger on each dimension.

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.
