Prepares codebases for security review using Trail of Bits' checklist. Helps set review goals, runs static analysis tools, increases test coverage, removes dead code, ensures accessibility, and generates documentation (flowcharts, user stories, inline comments). Use when preparing your own codebase to be audited by someone else, getting a repository review-ready before an external security review, deciding what to fix before auditors start, or asking what assessors need from a project. For…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Audit Prep Assistant

## Purpose

Helps prepare for a security review using Trail of Bits' checklist. A well-prepared codebase makes the review process smoother and more effective.

**Use this**: 1-2 weeks before your security audit

---

## The Preparation Process

### Step 1: Set Review Goals

Helps define what you want from the review:

**Key Questions**:
- What's the overall security level you're aiming for?
- What areas concern you most?
  - Previous audit issues?
  - Complex components?
  - Fragile parts?
- What's the worst-case scenario for your project?

Documents goals to share with the assessment team.

---

### Step 2: Resolve Easy Issues

Runs static analysis and helps fix low-hanging fruit:

**Run Static Analysis**:

For Solidity:
```bash
slither . --exclude-dependencies
```

For Rust:
```bash
dylint --all
```

For Go:
```bash
golangci-lint run
```

For Go/Rust/C++:
```bash
# CodeQL and Semgrep checks
```

Then I'll:
- Triage all findings
- Help fix easy issues
- Document accepted risks

**Increase Test Coverage**:
- Analyze current coverage
- Identify untested code
- Suggest new tests
- Run full test suite

**Remove Dead Code**:
- Find unused functions/variables
…

How to install

The exact contents, by fingerprint
mdr add trailofbits/skills/audit-prep-assistant@sha256:d639b411a315ea94

The line at the top of this page pins the label git:20260825.32ad9e6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
