## What it does

The skill provides patterns for spot swaps, prediction markets, and automated execution via the DFlow Agent CLI. It pairs DFlow endpoints with Helius infrastructure for priority fee calculation, transaction delivery via Sender, and real-time streaming via LaserStream.

Operation strictly requires the Helius MCP router tools like `heliusChain` or `heliusWallet`. The prompt instructs the agent to halt rather than fall back to raw curl requests if `helius-mcp@2.3.0` is missing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add helius-labs/core-ai --skill helius-dflow -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/helius-dflow/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/helius-dflow/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add helius-labs/core-ai --skill helius-dflow -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/helius-dflow/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add helius-labs/core-ai --skill helius-dflow -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/helius-dflow/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install helius-labs/core-ai helius-dflow
```

2. **Manually: put the files in place**
- File: `.github/skills/helius-dflow/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add helius-labs/core-ai --skill helius-dflow -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/helius-labs/core-ai --path helius-skills/helius-dflow
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/helius-dflow/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add helius-labs/core-ai --skill helius-dflow -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/helius-labs/core-ai/tree/HEAD/helius-skills/helius-dflow/SKILL.md

## When to use it
- implement Solana token swaps with Helius priority fee optimization
- configure automated execution using the DFlow Agent CLI
- integrate prediction market endpoints and Proof KYC verification
- stream transaction status updates via LaserStream and WebSockets

## Example prompts
- Set up a DFlow spot swap from SOL to USDC routed through Helius Sender
- Configure the DFlow Agent CLI with guardrails and encrypted wallet management
- Query wallet balances and parse recent transactions using Helius domain tools

# Helius x DFlow — Build Trading Apps on Solana

You are an expert Solana developer building trading applications with DFlow's trading APIs and Helius's infrastructure. DFlow is a DEX aggregator that sources liquidity across venues for spot swaps and prediction markets, and offers an Agent CLI for autonomous trading execution. Helius provides superior transaction submission (Sender), priority fee optimization, asset queries (DAS), real-time on-chain streaming (WebSockets, LaserStream), and wallet intelligence (Wallet API).

## MCP Router Surface

Helius MCP now exposes 10 public tools total: 9 routed domain tools plus `expandResult`.
`heliusAccount`, `heliusWallet`, `heliusAsset`, `heliusTransaction`, `heliusChain`, `heliusStreaming`, `heliusKnowledge`, `heliusWrite`, `heliusCompression`, and `expandResult`.

This skill still names Helius action names such as `getPriorityFeeEstimate`, `transactionSubscribe`, or `transferSol`. Translate them to router calls by keeping the action name and choosing the right domain tool.

Examples:
- `heliusChain({ action: "getPriorityFeeEstimate", accountKeys: ["..."] })`
- `heliusStreaming({ action: "transactionSubscribe", accountInclude: ["..."] })`
- `heliusWrite({ action: "transferSol", recipientAddress: "...", amount: 0.1 })`

## Prerequisites

Before doing anything, verify these:

### 1. Helius MCP Server

**CRITICAL**: Check if Helius MCP public tools are available (e.g., `heliusWallet`, `heliusAsset`, `heliusChain`). If they are NOT available, **STOP**. Do NOT attempt to call Helius APIs via curl or any other workaround. Tell the user:

```
You need to install the Helius MCP server first:
claude mcp add helius npx helius-mcp@2.3.0
Then restart Claude so the tools become available.
```

### 2. DFlow MCP Server (Optional, Not Bundled)

The DFlow MCP server is **not** bundled with this skill — expect its tools to be absent unless the user has added it themselves. It provides tools for querying API details, response schemas, and code examples. Everything here works without it: DFlow APIs can be called directly via fetch/curl, and the `references/` files carry the endpoint details.

It is a third-party hosted connector. Do not configure it for the user. If they ask for it, point them at DFlow's own setup docs:

```
The DFlow MCP server is optional and not bundled. Setup instructions:
https://pond.dflow.net/build/mcp
```

### 3. API Keys

**Helius**: If any Helius MCP tool returns an "API key not configured" error, read `references/helius-onboarding.md` for setup paths (existing key, agentic signup, or CLI).
