Independent AI assessment: clean. LPM AI assessed this version as clean; the assessments disagree.

OpenSSF/OSV advisory MAL-2026-13977 confirms this npm version as malicious. Package name resembles the widely-used 'cspell' library but its main entry (index.js) exports an empty object and provides no functionality. Its package.json pins its sole dependency 'ltidisafe' to a raw HTTPS URL on a Google Cloud Storage bucket (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.6.7.tgz) rather than a registry-published, version-pinned artifact...

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed package attack surface was found. The package itself only exports an empty object; its manifest references a remote dependency tarball.

- **Trigger:** Dependency installation fetches the declared tarball.

- **Impact:** No malicious package behavior is established from this source.

- **Evidence paths:** package.json, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-13T23:45:11.380Z

### AI review details

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

- **Mechanism:** Remote tarball dependency reference only.

- **Rationale:** Direct inspection found no lifecycle execution or runtime capability beyond an empty export. The remote dependency URL is a supply-chain concern but is not proof that this package is malicious.

- **Files touched:** package.json, index.js

- **Network endpoints:** https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.6.7.tgz

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json pins its only dependency to a remote Google Cloud Storage tarball, creating an external supply-chain dependency.

- **Evidence against:** No preinstall, install, or postinstall lifecycle hook is declared., The sole runtime entrypoint exports an empty object and contains no execution, file, network, or child-process behavior., No concrete malicious behavior is present in the inspected package source.
