## Security analysis

### Published attack-surface review

- **Summary:** No confirmed attack surface is established. Importing the package exposes only fixed-string functions.

- **Trigger:** User explicitly imports \`prettier-plugin-base\` and calls a \`line\*\` function.

- **Impact:** No observed credential access, network activity, persistence, execution, or file mutation.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-14T07:45:08.269Z

### AI review details

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

- **Mechanism:** Static local string-returning exports only.

- **Rationale:** Direct source inspection shows a minimal lyric utility with no install-time or runtime attack behavior. The unrelated dependency declaration is not executed or referenced by this package's source.

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

### Review decision

- **Verdict:** Clean

- **Confidence:** 99.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** \`package.json\` has no preinstall/install/postinstall/prepare lifecycle hook., \`index.js\` only exports five synchronous functions returning fixed strings., \`README.md\` documents the same local lyric-returning API., No network, filesystem-write, environment, shell, eval, or dynamic-loading primitive appears in package source.
