## What it does

The skill turns a plain-language question into BlackForge tool calls. It drives five MCP tools: `blackforge_catalog` (venues and metrics), `blackforge_symbols` (a venue's pairs), `blackforge_latest` (last closed bucket), `blackforge_series` (one metric over a range) and `blackforge_usage` (quota left). The CLI mirrors them: `blackforge catalog`, `blackforge symbols`, `blackforge latest`, `blackforge series`, `blackforge usage`.

Coverage is 9 spot exchanges (binance, bitget, bybit, coinbase, gate, kraken, kucoin, mexc, okx) and 14,000+ spot pairs, with 169 measurement columns per pair per closed minute. Granularity follows the plan: `1m` on Ultra and PAYG, `5m` on Max, `1h` on Pro, `1d` on Free. So on a free key the "latest" row can be a day old — worth checking which bucket length you actually got back.

The skill never builds HTTP requests or hardcodes an endpoint; everything goes through the BlackForge tools. Each column is a measurement with a definition and a unit, not a trade call. Ask "should I buy ETH right now" and it will not fire: it shows what the book and the tape measured, then stops. Live formulas computed every second are an Ultra feature this skill does not drive — those live in the BlackForge agent or the `/v1/formulas` API.

## When to use it
- check order-book depth for a pair on one venue
- compare taker buy and sell volume over a range
- see how much liquidity left the bid side
- find out which pairs a venue lists
- check how much quota is left on a key

## Example prompts
- show me the latest stats for BTCUSDT on binance
- how did bid depth within 5% move for ETH-USDT on okx over the past week
- which pairs does kraken list

  Answer crypto market-data questions with BlackForge. Use this skill whenever the user asks about
  order-book or trade data for a coin on a spot venue — its latest stats on an exchange,
  order-book depth or resting/pulled liquidity for a pair, taker buy-vs-sell volume, order-ladder
  rungs, price-level lifetime, trade timing, outsized trades, or market-cap/attention enrichment;
  when they want to pull, chart or compare a metric over a time range; or when they ask which pairs
  a venue lists. Covers 9 spot exchanges (binance, bitget, bybit, coinbase, gate, kraken, kucoin,
  mexc, okx) and 14,000+ spot pairs — 169 measurement columns per pair per closed
  minute (1m on Ultra/PAYG, 5m/1h/1d rollups on every plan). Trigger even when BlackForge is not named but the question is
  about crypto market data on a venue. Drives the BlackForge MCP tools (blackforge_catalog /
  blackforge_symbols / blackforge_latest / blackforge_series / blackforge_usage) or the `blackforge`
  CLI; never reimplements the API. Every returned column is a measurement, not a trade call.

# BlackForge market-data

BlackForge is a **raw market-data** product: for every `(exchange, symbol)` it stores one wide row
per closed **minute** (one-minute rows; history before the switch to them is 5-minute rows),
**169 measurement columns** across 14,000+ spot pairs, served at `1m`, `5m`, `1h` and `1d` —
order-book depth, resting-liquidity dynamics, trade-flow and trade-timing measurements, plus
market-cap and attention enrichment, and a per-row quality bitmask. This skill lets you answer a
plain-language market-data question by calling BlackForge's own tools and reading the rows back
**as measurements**.

You are a thin orchestration + interpretation layer. **Never** build HTTP requests, curl the API,
or hardcode an endpoint URL. Always go through the MCP tools or the `blackforge` CLI. Your job is to
know the vocabulary (which metric answers which question), run the right call, and explain the
numbers correctly.

## What BlackForge is — and is not

It is a measurement feed. Each column has a precise definition (e.g. *"resting sell liquidity from
the best ask up to +100%"*, *"quote notional that left the bid side of the book"*, *"median
lifetime of a price level created and removed inside the window"*). Present results in exactly that
register: **a measurement with a definition and a unit**.

It describes what happened in the book and on the tape — it does not tell the user what will happen
next or what to trade. Do not describe any column, or the data as a whole, using the words **signal,
pump, anomaly, probability-scored, alpha, prediction, detection, or alert**, and do not imply
```
