Install-time setup auto-adds the package-owned /greprag skill to existing Claude Code and Codex skill directories. Explicit init can register hooks that transmit configured memory data to the package API. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-08T10:23:09.490Z - **Finished:** 2026-08-08T10:23:55.131Z - **Download time:** 507 ms - **Static scan time:** 5967 ms - **AI review time:** 39166 ms - **Total time:** 45641 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time setup auto-adds the package-owned /greprag skill to existing Claude Code and Codex skill directories. Explicit init can register hooks that transmit configured memory data to the package API. - **Trigger:** npm postinstall for skill sync; explicit greprag init for hooks/plugins. - **Impact:** Changes agent extension behavior and can send configured session-derived data to the vendor service. - **Evidence paths:** package.json, scripts/postinstall.js, dist/commands/init.js, dist/hook.js, dist/email-send.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T10:23:55.131Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** package-owned agent skill installation and opt-in lifecycle-hook telemetry - **Rationale:** The automatic skill sync is an unconsented first-party agent-extension setup, which warrants a warning under policy. The higher-impact hook and network behavior is explicit-init and user-trust gated, so no concrete malicious chain is established. - **Files touched:** ~/.claude/skills/greprag, ~/.codex/skills/greprag, ~/.claude/docs/chip-spawn.md, ~/.codex/hooks.json, ~/.greprag/.env, ~/.config/opencode/plugins/greprag-memory.js - **Network endpoints:** https://api.greprag.com, https://registry.npmjs.org/greprag/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.js automatically., scripts/postinstall.js copies bundled greprag skill into detected ~/.claude/skills and ~/.codex/skills., dist/commands/init.js writes ~/.codex/hooks.json and registers lifecycle hooks when explicitly invoked., dist/hook.js sends captured hook-derived turn/procedure data to api.greprag.com., dist/email-send.js can read requested attachment paths and POST them as email attachments. - **Evidence against:** postinstall.js performs local skill copies only; no network or child-process execution., Hook and plugin setup requiring config writes is behind explicit greprag init commands., Codex setup instructs the user to trust hooks in the host UI., No obfuscated payload, credential harvesting, or destructive install-time behavior found. ## Public findings ### 1.
