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 | $0.00448 |
| Opus 5 | $0.00026 | $0.00224 |
| Sonnet 5 | $0.00011 | $0.00090 |
| Haiku 4.5 | $0.00005 | $0.00045 |
Grade A, and why
crypto-watch 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 7d 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
Crypto Watch
Quote crypto prices and run threshold alerts. Read-only market data; the only mutation is sending an alert message.
Spot price
CoinGecko's simple-price endpoint is keyless:
uv run python optional-skills/finance/crypto-watch/scripts/prices.py \
bitcoin ethereum solana --vs usd
Coin IDs are CoinGecko slugs (bitcoin, not BTC). Resolve tickers to slugs via
the /coins/list endpoint if the user gives a symbol.
Watchlist + alerts
Store watches in vault/finance/crypto-watchlist.json:
[
{"coin": "bitcoin", "vs": "usd", "above": 80000, "below": null, "armed": true}
]
On each scheduled tick:
- Fetch current prices for all armed watches in one batched call.
- For each, compare against
above/below. - On a crossing, send one alert and set
armed: false(re-arm manually) so it doesn't spam every tick.
Delivery (gated)
Alerts are outbound messages — send them through the chat.send capability gate
with an audit trail. Register the tick as a scheduled job (see
.claude/sections/03_*); do not busy-poll.
Disclaimer
Surface a brief "not financial advice" note the first time a session gives prices or sets an alert.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
