Installation mutates a third-party AI-agent dependency in node\_modules without user action. Runtime also installs and patches an agent extension under Xyne-managed state. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-08-09T15:13:02.445Z - **Finished:** 2026-08-09T15:14:13.231Z - **Download time:** 4044 ms - **Static scan time:** 3396 ms - **AI review time:** 63344 ms - **Total time:** 70786 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation mutates a third-party AI-agent dependency in node\_modules without user action. Runtime also installs and patches an agent extension under Xyne-managed state. - **Trigger:** npm postinstall; subsequent Xyne CLI startup - **Impact:** Alters upstream agent behavior and introduces package-managed executable extension code. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/patch-pi-auth-guidance.js, scripts/patch-pi-retry-classifier.js, dist-lib/src/agent/runtime/embedded-pi-runtime.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T15:14:13.231Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic third-party AI-agent code and extension mutation - **Attack narrative:** On npm installation, postinstall rewrites two files in the external pi-coding-agent dependency, including its authentication guidance. On Xyne startup, the embedded runtime automatically installs pi-goal-pro into ~/.xyne/agent/npm and text-patches it. These are unconsented mutations of a foreign AI-agent control surface rather than necessary launcher behavior. - **Rationale:** Direct source inspection confirms install-time modification of a third-party AI-agent dependency. This meets the firewall block boundary for unconsented postinstall mutation of a foreign AI-agent control surface. - **Files touched:** scripts/postinstall.js, scripts/patch-pi-auth-guidance.js, scripts/patch-pi-retry-classifier.js, node\_modules/@earendil-works/pi-coding-agent/dist/core/auth-guidance.js, node\_modules/@earendil-works/pi-coding-agent/dist/core/agent-session.js, ~/.xyne/agent/npm ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/patch-pi-auth-guidance.js rewrites pi-coding-agent auth guidance to promote \`xyne setup\`., scripts/patch-pi-retry-classifier.js rewrites pi-coding-agent runtime code during install., dist-lib/src/agent/runtime/embedded-pi-runtime.js silently installs and patches pi-goal-pro on CLI startup. - **Evidence against:** dist/index.js only resolves and launches the matching Xyne platform binary., Inspected lifecycle patches are fixed local replacements; no credential harvesting or exfiltration was found. ## Public findings ### 1.
