The postinstall hook only rebrands installed harness display assets, while networked credential use is part of the user-invoked Token Harbor client flow. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 91.0% - **Started:** 2026-08-14T14:42:17.151Z - **Finished:** 2026-08-14T14:43:07.628Z - **Download time:** 506 ms - **Static scan time:** 89 ms - **AI review time:** 49881 ms - **Total time:** 50477 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The postinstall hook only rebrands installed harness display assets, while networked credential use is part of the user-invoked Token Harbor client flow. - **Trigger:** npm postinstall for branding; CLI login/debug or normal harness use for runtime network activity. - **Impact:** Modifies installed dependency presentation; credentials are used only with the package-aligned Token Harbor service. - **Evidence paths:** package.json, bin/rebrand.mjs, bin/auth.mjs, bin/halyard.mjs, bin/daemon.mjs, profile/halyard.patch.yml - **Review source:** ai\_review - **Reviewed:** 2026-08-14T14:43:07.628Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Dependency branding rewrite and Token Harbor CLI/harness launch. - **Rationale:** Source inspection confirms a transparent branding postinstall and a package-aligned authentication/client flow, not credential theft or remote payload execution. The scanner's credential-exfiltration label conflates authorized API authentication with exfiltration. - **Files touched:** bin/rebrand.mjs, bin/auth.mjs, bin/halyard.mjs, bin/daemon.mjs - **Network endpoints:** https://tokenharbor.ai, https://tokenharbor.ai/v1/models, https://registry.npmjs.org/ ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** Postinstall rewrites display strings and a favicon in its @deepseek-ai dependency., Runtime accepts/stores an API key and uses it for Token Harbor API calls. - **Evidence against:** The install hook is limited to dependency branding assets; no network, credential collection, or agent-config mutation occurs there., Authentication is invoked by the CLI when login/no key is needed and stores its returned key with mode 0600., Observed network use is Token Harbor authentication/models and npm registry version checking; no third-party exfiltration endpoint found., Child processes only launch the configured harness or an explicit browser opener. ## Public findings ### 1.
