## Workspace crates

| Crate | Description |
|---|---|
| [`marketsurge-client`](client/) | HTTP client library for the MarketSurge GraphQL API |
| [`marketsurge-agent`](agent/) | CLI binary for querying market data |

`marketsurge-agent` depends on `marketsurge-client`. The client crate has no dependency on the agent.

## Installation

### Pre-built binaries

Download a binary from the [latest release](https://github.com/major/marketsurge-rs/releases/latest). Builds are available for Linux, macOS, and Windows.

### cargo-binstall

```bash
cargo binstall marketsurge-agent
```

### Build from source

```bash
cargo install --path agent
```

Requires Rust 1.95.0 or later.

## Usage

The CLI reads browser cookies from Firefox automatically for authentication. Log in to [MarketSurge](https://marketsurge.investors.com) in your browser first, then run commands.

Output goes to stdout as compact JSON. Pipe through `jq` for pretty-printing. Logs and errors go to stderr.

```bash
# Fund ownership summary for a stock
marketsurge-agent ownership summary AAPL

# Output as JSON objects instead of the default array-of-arrays format
marketsurge-agent --json-objects ownership summary AAPL

# Generate shell completions
marketsurge-agent completions zsh > _marketsurge-agent
```

## Development

```bash
# Full check (fmt + clippy + test + docs)
make check

# Individual targets
make fmt        # cargo +nightly fmt
make clippy     # cargo clippy -- -D clippy::all
