book

A command that shows the top buy and sell orders for a cryptocurrency pair. An order book is a live list of offers to buy and sell, while the spread is the gap between the best prices.

In plain words
What is it for?
Use it to inspect both sides of a pair's order book, compare depth, and report the spread and any imbalance in available liquidity.
Why use it?
It provides a timestamped view of available order sizes and reveals how easily trades may be executed on one venue.

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.

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

book scanned grade A with 1 finding 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 yesterday.

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.

What it actually says

Task

Show the order book for $ARGUMENTS.

moshcode crypto book $ARGUMENTS --depth 10 --json

Fallback: curl -sS "https://advis0r.com/api/crypto/orderbook?symbol=$ARGUMENTS&depth=10"

Reading the response

orderbooks[] each carry a timestamp, bids[] and asks[], every level a { price, size }. Bids descend from the best bid; asks ascend from the best ask.

Rules

  • Report the spread in basis points, not just in dollars — a $50 spread means something different on BTC than on ETH.
  • Size is depth on one venue, not the market. Do not describe the book as "the market's" depth, and do not extrapolate what a large order would fill at.
  • A book is a snapshot of an instant. Timestamp it.
  • If one side is much thinner than the other, say so plainly rather than reading it as a directional signal — it is a liquidity observation.
  • End with the response's own disclaimer.

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.

book is a command published in the GitHub repository moshcoder/moshcode (2 stars, last pushed yesterday), licensed MIT. It adds 14 tokens to every session and 298 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
