User-invoked Happy CLI sessions connect to its configured service and relay coding-session data. Claude mode supplies a temporary hook-settings file that invokes package scripts and forwards session-start data to a loopback hook server. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-05T12:51:37.406Z - **Finished:** 2026-08-05T12:52:44.134Z - **Download time:** 2278 ms - **Static scan time:** 4271 ms - **AI review time:** 60178 ms - **Total time:** 66728 ms ## Security analysis ### Published attack-surface review - **Summary:** User-invoked Happy CLI sessions connect to its configured service and relay coding-session data. Claude mode supplies a temporary hook-settings file that invokes package scripts and forwards session-start data to a loopback hook server. - **Trigger:** Running happy claude or related Happy session commands after installation. - **Impact:** A user choosing this remote/mobile coding client entrusts session data and command results to its configured service. - **Evidence paths:** package.json, scripts/unpack-tools.cjs, scripts/fix-node-pty-perms.cjs, scripts/session\_hook\_forwarder.cjs, dist/index-8FI6shIm.mjs, dist/types-jp-O9NuY.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-05T12:52:44.134Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Temporary agent hook setup plus remote session synchronization. - **Rationale:** No concrete malicious install-time behavior, stealth persistence, or unconsented foreign control-surface mutation was found. Its user-invoked agent-hook and remote-session capabilities remain a meaningful extension lifecycle risk. - **Files touched:** scripts/unpack-tools.cjs, tools/unpacked, scripts/fix-node-pty-perms.cjs, node\_modules/node-pty/prebuilds/darwin-arm64/spawn-helper, node\_modules/node-pty/prebuilds/darwin-x64/spawn-helper, ~/.happy/tmp/hooks/session-hook-\.json, scripts/session\_hook\_forwarder.cjs - **Network endpoints:** https://saycode.ai, http://127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall scripts., scripts/unpack-tools.cjs extracts bundled native archives to tools/unpacked., dist/index-8FI6shIm.mjs creates temporary Claude SessionStart/PreToolUse hook settings., scripts/session\_hook\_forwarder.cjs forwards hook stdin to localhost., dist/types-jp-O9NuY.mjs defaults the service URL to https://saycode.ai and syncs sessions. - **Evidence against:** Postinstall only verifies dependencies, unpacks package-owned tools, and fixes node-pty execute bits., Hook settings are per-session files under ~/.happy/tmp/hooks and are deleted after use., The hook forwards only to 127.0.0.1; no foreign agent config is installed., Remote debug logging requires both explicit DANGEROUSLY\_LOG\_TO\_SERVER\_FOR\_AI\_AUTO\_DEBUGGING and HAPPY\_SERVER\_URL. ## Public findings ### 1.
