## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. Runtime code is a local TypeScript/Jest transformer; the CLI has one explicit configuration-file creation action.

- **Trigger:** Jest invokes the transformer, or the user runs ts-vitest config:init.

- **Impact:** Reads a selected project tsconfig during transformation; explicit CLI may create jest.config.js if absent.

- **Evidence paths:** package.json, dist/index.js, dist/preset.js, dist/transformer.js, dist/cli.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T06:50:09.955Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Local tsconfig parsing, TypeScript transpilation, and explicit Jest config generation.

- **Rationale:** Static inspection found package-aligned local transformation behavior and a user-invoked config initializer only. No install-time execution or concrete exfiltration, remote execution, persistence, or destructive behavior is present.

- **Files touched:** dist/transformer.js, dist/cli.js, jest.config.js, tsconfig.json

### Review decision

- **Verdict:** Clean

- **Confidence:** 98.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has only a prepublishOnly verification script; no install lifecycle hook., dist/index.js only exports the local TypeScript Jest transformer., dist/transformer.js reads TypeScript config and transpiles supplied test source locally., dist/cli.js writes jest.config.js only after explicit ts-vitest config:init., No network, child-process, eval, credential, or persistence primitives found in distributed JS.

## Public findings

### 1. Low: Non Install Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 80.0%

### 2. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 3. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%

Package source references filesystem APIs.
