What is crypto-hardened?

A cryptocurrency market monitor built on CCXT, a library that connects to many crypto exchanges. It retrieves prices and market information and can watch for configured price or percentage changes.

Use it to view current prices, changes, volume, candlestick history, and order books; monitor a trading pair continuously; and set price or percentage-change alerts.

It brings data from different exchanges into one command-line workflow, so checking markets and waiting for alert conditions does not require separate tools.

Token cost

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	$0.00056	$0.02230
Opus 5	$0.00028	$0.01115
Sonnet 5	$0.00011	$0.00446
Haiku 4.5	$0.00006	$0.00223

Security

Grade A, and why

crypto-hardened 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 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.
