## Security analysis

### Published attack-surface review

- **Summary:** Install-time code mutates the consuming project by seeding build configs, GitHub workflows, release scripts, and assets. No confirmed exfiltration or hidden payload behavior was found.

- **Trigger:** npm install of the package

- **Impact:** Consumer repositories may gain a release workflow with repository-write and npm-publish capability when subsequently triggered.

- **Evidence paths:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, src/init.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T17:11:51.872Z

### AI review details

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

- **Mechanism:** postinstall copies package-owned project and CI templates

- **Rationale:** This is not concrete malware, but an install hook automatically adds privileged downstream CI/release behavior. Warn so consumers can review the seeded workflow before relying on it.

- **Files touched:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, .github/workflows/release.yml, .github/workflows/verify-npm-token.yml, scripts/auto-changeset.sh, .changeset/config.json, docs/assets/doikayt-logo.png, docs/assets/doikayt-logo.svg

- **Network endpoints:** https://registry.npmjs.org

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall automatically., src/postinstall.js seeds consumer .github workflows and scripts., Seeded release workflow can publish with NODE\_AUTH\_TOKEN., src/init.js explicitly modifies consumer package.json.

- **Evidence against:** Writes are documented package configuration/scaffolding., Postinstall copies only absent files and does not overwrite., No credential harvesting, exfiltration, or remote payload execution found., Workflow endpoints are npm registry only; token check uses npm whoami.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@doikayt/typescript-build-config@0.1.15/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = node src/postinstall.js
```

### 2. Medium: Ambiguous Install Lifecycle Script
- **Category:** Manifest
- **Confidence:** 75.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@doikayt/typescript-build-config@0.1.15/package.json>)

Install-time lifecycle script is not statically allowlisted and needs review.

Public source snippet (untrusted):

```json
scripts.postinstall = node src/postinstall.js
```

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

Package declares npm scripts.

### 4. Medium: Environment Vars
- **Category:** Source
- **Confidence:** 75.0%

Package source references environment variables.

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

Package source references filesystem APIs.

### 6. Medium: Ships Build Helper
- **Category:** Artifact Inventory
- **Confidence:** 70.0%
- **Path:** src/pipeline/auto-changeset.sh
- **Public source:** [View source](<https://unpkg.com/@doikayt/typescript-build-config@0.1.15/src/pipeline/auto-changeset.sh>)

Package ships non-JavaScript build or shell helper files.

Public source snippet (untrusted):

```shell
path = src/pipeline/auto-changeset.sh
kind = build_helper
sizeBytes = 2940
magicHex = [redacted]
```

### 7. High: Ships High Entropy Blob
- **Category:** Artifact Inventory
- **Confidence:** 75.0%
- **Path:** assets/jews-support-a-free-palestine-poster.pdf
- **Public source:** [View source](<https://unpkg.com/@doikayt/typescript-build-config@0.1.15/assets/jews-support-a-free-palestine-poster.pdf>)

Package ships high-entropy non-source blobs.

Public source snippet (untrusted):

```text
path = assets/jews-support-a-free-palestine-poster.pdf
kind = high_entropy_blob
sizeBytes = 1040003
magicHex = [redacted]
```

### 8. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
