## What it does

The tool searches repository files for Rust sources and `Anchor.toml` configs. It checks code against six security patterns in the Solana execution model. These include unverified program IDs during CPI calls and improper bump calculations in PDA seeds.

The scan produces a coverage summary listing every tested pattern. The report highlights missing ownership checks prior to data decoding and omitted signer checks. Ready-to-use code fixes accompany each finding.

The sysvar rule targets projects using `solana-program` releases older than 1.8.1. Without Rust sources or Anchor definitions, the scanner will find nothing to evaluate.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add trailofbits/skills --skill solana-vulnerability-scanner -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add trailofbits/skills --skill solana-vulnerability-scanner -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add trailofbits/skills --skill solana-vulnerability-scanner -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install trailofbits/skills solana-vulnerability-scanner
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add trailofbits/skills --skill solana-vulnerability-scanner -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/trailofbits/skills --path plugins/building-secure-contracts/skills/solana-vulnerability-scanner
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add trailofbits/skills --skill solana-vulnerability-scanner -a opencode
```

### Claude.ai

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

## When to use it
- detect arbitrary cross-program invocation flaws with unverified targets
- verify account deserialization logic against missing owner checks
- spot program-derived address derivation using arbitrary bumps
- flag state modifications missing signer authentication

## Example prompts
- Scan `programs/` for unsafe cross-program invocations and unverified PDA derivations
- Audit the Anchor accounts struct to ensure signer constraints are in place
- Review Solana program instructions for instruction introspection flaws
