Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed attack surface was established. Installation only prints a terminal message, and the library formats ANSI-colored text. - **Trigger:** Package installation runs the post-install script; importing the library creates text-formatting helpers. - **Impact:** No file, network, credential, subprocess, or configuration effect was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-11T18:47:10.679Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Terminal message output and ANSI text wrapping. - **Rationale:** The automatic post-install hook is unnecessary and noisy, but direct inspection shows it only prints a message based on terminal settings. No concrete malicious behavior or unresolved dangerous capability was found. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package runs a post-install script automatically., The install script reads terminal settings and prints a warning message. - **Evidence against:** The install script has no file writes, network access, subprocess execution, or dynamic code execution., The runtime entry point only builds ANSI text-wrapping functions., No credential harvesting, persistence, or destructive behavior was found. ## Affected versions and remediation This report applies to ansi-tint@1.4.5. - Review the evidence and your use of ansi-tint@1.4.5 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
