# Custom Instructions

> Guide Strix with custom testing instructions

Use instructions to provide context, credentials, or focus areas for your scan.

## Inline Instructions

```bash theme={null}
strix --target https://app.com --instruction "Focus on authentication vulnerabilities"
```

## File-Based Instructions

For complex instructions, use a file:

```bash theme={null}
strix --target https://app.com --instruction-file ./pentest-instructions.md
```

## Common Use Cases

### Authenticated Testing

```bash theme={null}
strix --target https://app.com \
  --instruction "Login with email: test@example.com, password: TestPass123"
```

### Focused Scope

```bash theme={null}
strix --target https://api.example.com \
  --instruction "Focus on IDOR vulnerabilities in the /api/users endpoints"
```

### Exclusions

```bash theme={null}
strix --target https://app.com \
  --instruction "Do not test /admin or /internal endpoints"
```

### API Testing

```bash theme={null}
strix --target https://api.example.com \
  --instruction "Use API key header: X-API-Key: abc123. Focus on rate limiting bypass."
```

## Instruction File Example

```markdown instructions.md theme={null}
# Penetration Test Instructions

## Credentials
- Admin: admin@example.com / AdminPass123
- User: user@example.com / UserPass123

## Focus Areas

<Tip>
  Be specific. Good instructions help Strix prioritize the most valuable attack paths.
