Explicit CLI login contacts Token Harbor and stores the resulting approved key in the package-specific home directory; no confirmed malicious chain is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 91.0% - **Started:** 2026-08-14T14:19:30.339Z - **Finished:** 2026-08-14T14:20:09.885Z - **Download time:** 503 ms - **Static scan time:** 86 ms - **AI review time:** 38956 ms - **Total time:** 39546 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation rewrites display branding in the installed DeepSeek Harness dependency. Explicit CLI login contacts Token Harbor and stores the resulting approved key in the package-specific home directory; no confirmed malicious chain is present. - **Trigger:** npm postinstall; later explicit halyard invocation/login - **Impact:** Changes dependency display assets/text and configures a user-requested model-provider credential. - **Evidence paths:** package.json, bin/rebrand.mjs, bin/auth.mjs, bin/halyard.mjs, profile/halyard.patch.yml - **Review source:** ai\_review - **Reviewed:** 2026-08-14T14:20:09.885Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** dependency UI rebranding and Token Harbor device-code authentication - **Rationale:** The lifecycle mutation is an overt, bounded branding change rather than AI-agent control hijacking, and network/credential behavior is package-aligned explicit login. Static source inspection found no exfiltration, remote code loading, destructive action, or stealth persistence. - **Files touched:** bin/rebrand.mjs, bin/auth.mjs, bin/halyard.mjs, profile/halyard.patch.yml, node\_modules/@deepseek-ai/\*/lib/\*\*, node\_modules/@deepseek-ai/\*/dist/\*\*, node\_modules/@deepseek-ai/dsh-web-frontend/dist/favicon.svg, ~/.halyard/credentials.json - **Network endpoints:** https://tokenharbor.ai/api/cli/auth/init, https://tokenharbor.ai/api/cli/auth/status, https://tokenharbor.ai/v1 ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** postinstall rewrites human-readable branding and a dependency favicon., Explicit CLI login sends device metadata to Token Harbor and stores an approved API key locally. - **Evidence against:** No install-time network, shell, credential harvesting, or agent-control configuration writes found., Rebranding is limited to listed text extensions and a fixed favicon target., Credential flow is activated by CLI use, uses Token Harbor endpoints, and saves with mode 0600., Launcher invokes the pinned harness with user arguments; no eval or remote payload loading found. ## Public findings ### 1.
