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.

Security

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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/prices.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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:

  1. Fetch current prices for all armed watches in one batched call.
  2. For each, compare against above / below.
  3. 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.

Files

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.

Changes

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.
