Runtime network use is for the Token Harbor authentication/model service; no confirmed malicious attack surface was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 91.0% - **Started:** 2026-08-15T11:03:05.469Z - **Finished:** 2026-08-15T11:03:42.263Z - **Download time:** 763 ms - **Static scan time:** 283 ms - **AI review time:** 35747 ms - **Total time:** 36794 ms ## Security analysis ### Published attack-surface review - **Summary:** The install hook performs disclosed local UI/product-name rebranding of its direct harness dependency. Runtime network use is for the Token Harbor authentication/model service; no confirmed malicious attack surface was found. - **Trigger:** npm postinstall; user runs the halyard CLI or login command. - **Impact:** No exfiltration, remote payload execution, destructive action, or foreign AI-agent control-surface mutation identified. - **Evidence paths:** package.json, bin/rebrand.mjs, bin/auth.mjs, bin/halyard.mjs, bin/credentials.mjs, profile/halyard.patch.yml - **Review source:** ai\_review - **Reviewed:** 2026-08-15T11:03:42.263Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local rebranding plus user-invoked harness and authentication launcher. - **Rationale:** The lifecycle write is a constrained, disclosed rebranding operation on the package’s direct harness dependency. Source inspection found no concrete malicious chain or unconsented broad agent-control mutation. - **Files touched:** node\_modules/@deepseek-ai/\*/lib/\*, node\_modules/@deepseek-ai/\*/dist/\*, ~/.halyard/credentials.json, ~/.halyard/.credentials.yaml, ~/.halyard/settings.yaml - **Network endpoints:** https://tokenharbor.ai/api/cli/auth/init, https://tokenharbor.ai/api/cli/auth/status, 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 invokes a local rebranding script., The hook rewrites installed @deepseek-ai lib/dist text and UI branding. - **Evidence against:** No credential or workspace harvesting/exfiltration found., Authentication network calls occur only during user-invoked CLI login and use tokenharbor.ai., Launcher uses a separate ~/.halyard home and starts the declared harness with its overlay. ## Public findings ### 1.
