## Security analysis

### Published attack-surface review

- **Summary:** No confirmed attack surface beyond explicit runtime calls to two in-memory gas-report utilities. No install-time behavior or external interaction is present.

- **Trigger:** A consumer explicitly imports and calls the exported functions.

- **Impact:** No malicious behavior or side effects established.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-10T21:20:26.823Z

### AI review details

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

- **Mechanism:** Parses text reports and compares numeric gas values in memory.

- **Rationale:** Direct inspection shows a minimal package with no lifecycle hooks and only deterministic, in-memory parsing/comparison logic. Unused Node module imports do not create an attack path.

### Review decision

- **Verdict:** Clean

- **Confidence:** 99.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json defines only index.js and has no lifecycle scripts or dependencies., index.js exports pure parseGasReport and compareGasReports functions., No filesystem, network, shell, dynamic-code, or environment access is invoked; imported fs/path/os modules are unused.

## Public findings
