## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. The package exposes a user-invoked theme CLI and PostCSS plugin that process project theme files and generate local artifacts.

- **Trigger:** Explicit CLI command or PostCSS build using the plugin.

- **Impact:** Expected project-local output files only; no evidence of exfiltration, remote execution, or install-time activity.

- **Evidence paths:** package.json, packages/cli/package.json, packages/cli/src/config.ts, packages/cli/src/cli.ts, packages/cli/src/commands/build.ts, packages/core/src/plugin.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-08-11T12:40:05.089Z

### AI review details

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

- **Mechanism:** Local theme parsing, transformation, and artifact generation.

- **Rationale:** Direct inspection found no lifecycle hooks or malicious behavior. The flagged dynamic import is an explicit CLI configuration-loading feature, not import-time payload execution.

### Review decision

- **Verdict:** Clean

- **Confidence:** 97.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no preinstall/install/postinstall hooks., packages/cli/src/config.ts dynamically imports only an explicit or discovered project theme config during CLI use., CLI commands read theme inputs and write declared build artifacts; no network, shell, credential, or persistence logic found., packages/core/src/plugin.ts generates local CSS/type/JSON/docs/Tailwind artifacts from PostCSS theme input.
