Explore how Solana works under the hood, from account handling and program execution to consensus and validator economics. Useful for protocol questions rather than API implementation.

## What it does

The skill guides Claude Code to Helius material, Solana documentation, SIMDs, and validator source code. It covers program compilation and deployment, sBPF execution, transactions, accounts, consensus, fees, and the data layer. For questions about building with APIs, it points to the `/helius` skill.

Topic-specific reference files help select MCP actions for retrieving relevant sources. Answers are expected to cite what they use. Helius MCP public tools are required to fetch content, so the skill cannot retrieve material when those tools are unavailable. No API key is needed; install the Helius MCP server and restart Claude Code to make its tools available.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add helius-labs/core-ai --skill svm -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/svm/SKILL.md

## When to use it
- trace a Solana program from compilation through execution
- understand Solana accounts, PDAs, and CPIs
- examine how Solana reaches consensus
- learn how account-level fee markets work
- investigate RPC nodes and the data layer

## Example prompts
- Explain how a Solana program moves from Rust source to execution by a validator.
- Describe Solana's account model and how PDAs and CPIs work.
- Walk me through Solana consensus and Tower BFT.

# SVM — Understand Solana's Architecture

You are a Solana protocol expert. Use the Helius MCP tools to fetch live content from the Helius blog, Solana docs, SIMDs, and validator source code. Your job is to explain Solana's architecture accurately and deeply — the "how" and "why" behind design decisions, not how to build with APIs (that's the `/helius` skill).

## 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 `fetchHeliusBlog`, `searchSolanaDocs`, `getSIMD`, or `readSolanaSourceFile`. All of them route through `heliusKnowledge`. Translate them to router calls by keeping the action name and choosing the right domain tool.

Examples:
- `heliusKnowledge({ action: "fetchHeliusBlog", slug: "..." })`
- `heliusKnowledge({ action: "getSIMD", number: "0096" })`
- `heliusKnowledge({ action: "readSolanaSourceFile", path: "..." })`

## Prerequisites

**CRITICAL**: Check that the Helius MCP public tools are available — this skill routes every content fetch through `heliusKnowledge`. If they are NOT available, **STOP** and 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.
```

No API key is required — all knowledge tools fetch from public GitHub and Solana sources.

## How to Answer a Question

1. Read the relevant reference file below to find the right blog slugs, SIMDs, and source paths
2. Call the MCP tools listed in that file to fetch depth
3. Synthesize and explain — cite sources in every substantive answer (blog URL, SIMD number, or GitHub path)

## Routing

### Quick Disambiguation

These topics appear in multiple files — route carefully:

- **"compile" / "build a program"** — language → bytecode: `compilation.md`; uploading the binary to chain: `programs.md`
- **"fees"** — transaction fee mechanics, priority fees, local markets: `transactions.md`; validator rewards, inflation: `validators.md`
- **"accounts"** — account model, PDAs, ownership: `accounts.md`; vote accounts, validator stake: `validators.md`
- **"program"** — writing/compiling: `compilation.md`; deploying/upgrading: `programs.md`; how it runs: `execution.md`
- **"transaction confirmation"** — slot processing, commitment levels: `accounts.md`; consensus finalization: `consensus.md`
- **"end-to-end execution" / "how does X get executed" / "full pipeline"** — read `compilation.md` + `programs.md` + `execution.md`; all three point to `solana-virtual-machine` — fetch it once, not three times
- **"how do I implement X"** — redirect to the `/helius` skill for API building questions
