Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The install hook seeds package workflows under the package-owned Hermit home. An explicit token-claim command can reconfigure Claude Code and Codex to use a claimed gateway credential; this is a real AI-agent control-surface capability, but not an unconsented install-time hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-09-08T21:00:01.149Z - **Finished:** 2026-09-08T21:00:07.318Z - **Download time:** 1269 ms - **Static scan time:** 4899 ms - **AI review time:** 138653 ms - **Total time:** 6169 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The install hook seeds package workflows under the package-owned Hermit home. An explicit token-claim command can reconfigure Claude Code and Codex to use a claimed gateway credential; this is a real AI-agent control-surface capability, but not an unconsented install-time hijack. - **Trigger:** User runs the token-claim/aikey flow after installation; postinstall only seeds Hermit workflows. - **Impact:** Can redirect local Claude Code and Codex API traffic to a configured gateway using a claimed token. - **Evidence paths:** package.json, bin/postinstall.mjs, bin/lib/aikey.mjs, bin/lib/configEnvBackup.mjs, bin/lib/navigationCommand.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T21:00:07.318Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit credential injection into Claude/Codex runtime configuration - **Rationale:** No concrete malicious install-time behavior was found, but explicit agent credential/configuration mutation is a high-impact capability. The package should be warned rather than blocked. - **Files touched:** bin/postinstall.mjs, src/main/services/system-manager/builtin-workflows, ~/.hermit/.claude/workflow, ~/.claude/settings.json, ~/.codex/auth.json, ~/.codex/config.toml, ~/.hermit/agentcli.env.bak ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for block:** \`bin/postinstall.mjs\` runs on install and copies bundled workflows into \`~/.hermit/.claude/workflow\`., \`bin/lib/aikey.mjs\` writes claimed gateway credentials to \`~/.claude/settings.json\`, \`~/.codex/auth.json\`, and \`~/.codex/config.toml\`., \`bin/lib/configEnvBackup.mjs\` snapshots and restores those foreign Claude/Codex configuration files., \`bin/lib/aikey.mjs\` fetches a key bundle from the authenticated configured server before applying it. - **Evidence against:** \`postinstall\` performs no network requests, child-process launch, or external config writes outside the Hermit home tree., Workflow seeding is package-owned (\`~/.hermit/.claude/workflow\`) and preserves user-managed files without the Hermit marker., Claude/Codex credential changes are in the explicit token-claim flow, with backups and restoration support., No source evidence of install-time credential exfiltration, remote payload execution, or destructive actions was found. ## Affected versions and remediation This report applies to @yancyyu/agentcli@1.9.17. - Avoid installing @yancyyu/agentcli@1.9.17. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
