# solidity-auditor

Runs a security audit of your Solidity code while you develop: one pass over the repo or a single file, with a report at the end.

## What it does

The skill orchestrates a parallel smart contract audit: 12 agents work the code and the orchestrator folds their findings into one report. A default scan picks up every `.sol` file in the repo, but you can name a specific file instead — the exclude pattern does not apply then, and the file is scanned wherever it lives.

A default scan skips `node_modules/`, `lib/`, `artifacts/`, `cache/`, `out/`, `broadcast/`, `coverage/`, `typechain*/`, plus `interfaces/`, `mocks/`, `test/` and files matching `*.t.sol`, `*Test*.sol` or `*Mock*.sol`. Deploy scripts stay in scope: `script/`, `deploy/` and `*.s.sol` get audited like any other code, because a deploy script sets constructor arguments and hands over ownership.

The `--loop [N]` flag runs N passes in one scan, each pass told what the earlier ones found, ending in one combined report. `--loop` with no number means 3 passes. `--memory` keeps findings between scans in `.solidity-auditor/memory.tsv`, and it turns itself on whenever the pass count is above 1. `--file-output` copies the assembled report into your working directory; without it, nothing is written outside `.solidity-auditor/`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill solidity-auditor -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill solidity-auditor -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill solidity-auditor -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pashov/skills solidity-auditor
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill solidity-auditor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pashov/skills --path solidity-auditor
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill solidity-auditor -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/pashov/skills/tree/HEAD/solidity-auditor/SKILL.md

## When to use it
- check a contract for vulnerabilities before deploy
- audit one specific file instead of the whole repo
- combine findings from several passes into a single report
- carry findings over between scans in a ledger
- catch a deploy script that hands over ownership or seeds state wrong

## Example prompts
- audit this contract
- run the auditor in loop mode, 3 passes
- review contracts/Vault.sol for security

description: Security audit of Solidity code while you develop. Trigger on "audit", "check this contract", "review for security", "loop mode", "run the auditor in loop mode", "run 3 passes". Modes - default (full repo) or a specific filename. Loop mode runs several passes in one scan, each pass told what the earlier ones found, and ends in one combined report; it remembers findings between scans in a ledger.

# Smart Contract Security Audit

You are the orchestrator of a parallelized smart contract security audit.

## Mode Selection

**Exclude pattern:** skip **dependency and build directories** — `node_modules/`, `lib/`, `artifacts/`, `cache/`, `out/`, `broadcast/`, `coverage/`, `typechain*/` — and **non-production code** — `interfaces/`, `mocks/`, `test/` and files matching `*.t.sol`, `*Test*.sol` or `*Mock*.sol`.

**Deploy scripts stay in scope.** `script/`, `deploy/` and `*.s.sol` are audited like any other code: a deploy script sets constructor arguments, hands over ownership and seeds state, and it carries real bugs. Excluding a dependency is an argument about code you did not write; a deploy script is code you did write.

- **Default** (no arguments): scan all `.sol` files using the exclude pattern. Use Bash `find` (not Glob), exactly this command:

  ```bash
  find . -type f -name '*.sol' \
    -not -path '*/node_modules/*' -not -path '*/lib/*' -not -path '*/artifacts/*' \
    -not -path '*/cache/*' -not -path '*/out/*' -not -path '*/broadcast/*' \
    -not -path '*/coverage/*' -not -path '*/typechain*/*' \
    -not -path '*/interfaces/*' -not -path '*/mocks/*' -not -path '*/test/*' \
    -not -name '*.t.sol' -not -name '*Test*.sol' -not -name '*Mock*.sol'
  ```

  `-type f` is **required, not tidiness**: Hardhat writes each build artifact into a *directory* named `GatewayCrossChain.sol/`, so a `find` without it matches directories as if they were source files and hands them to `cat`. Do not drop it, and do not re-derive this command — paste it.

- **`$filename ...`**: scan the specified file(s) only. **The exclude pattern does not apply here.** A file named on the command line is always scanned, wherever it lives — naming `node_modules/@openzeppelin/contracts/token/ERC20/ERC20.sol` scans that file. The pattern chooses what a *default* scan discovers; it never overrides an explicit request.

**Flags:**

- `--file-output` (off by default): **copy** the assembled report into the working directory (name per `{resolved_path}/report-formatting.md`). The flag never causes a report to be produced — every scan assembles `.solidity-auditor/runs/{stamp}/full-report.md` whether it is passed or not. It only decides whether a copy lands where the runner can see it.
