## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. The install hook executes test.js, which only self-imports and calls absent exports inside a catch block.

- **Trigger:** npm postinstall

- **Impact:** At most a caught runtime error written to stderr; no file, network, or process action is present.

- **Evidence paths:** package.json, test.js, readme.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T07:45:09.211Z

### AI review details

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

- **Mechanism:** Nonfunctional self-require and caught function calls

- **Rationale:** Direct inspection found a broken postinstall hook but no concrete harmful behavior. Dependency names and lifecycle presence are insufficient to establish malicious intent.

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

### Review decision

- **Verdict:** Clean

- **Confidence:** 97.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for:** package.json defines postinstall: node test.js., package.json lists child\_process and os dependencies, but no package source imports them.

- **Evidence against:** test.js is the only executable source and contains no network, filesystem, shell, eval, or environment access., During postinstall, test.js self-requires the package, obtains no declared exports, and catches the resulting call error., No source contains credential collection, payload download, persistence, or destructive operations.
