On npm postinstall, the package installs its own skill into detected Claude Code and Codex homes. Subsequent explicit setup can configure hooks and transmit captured OpenCode conversation data to the package API. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-22T23:34:42.577Z - **Finished:** 2026-08-22T23:35:43.439Z - **Download time:** 510 ms - **Static scan time:** 7582 ms - **AI review time:** 52769 ms - **Total time:** 60862 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package installs its own skill into detected Claude Code and Codex homes. Subsequent explicit setup can configure hooks and transmit captured OpenCode conversation data to the package API. - **Trigger:** npm install when ~/.claude or ~/.codex exists; explicit greprag init or watcher use for hooks/capture. - **Impact:** The installed skill can influence agent behavior; configured capture sends conversation content to the vendor service. - **Evidence paths:** package.json, scripts/postinstall.js, dist/commands/init.js, dist/commands/opencode-watch.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T23:35:43.439Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** first-party AI-agent skill installation with opt-in hook and memory capture - **Rationale:** The package performs unconsented postinstall setup in AI-agent skill directories, so it warrants a warning under the lifecycle policy. Its higher-impact hook and memory-upload features are explicit, authenticated setup paths rather than a concrete malicious install chain. - **Files touched:** scripts/postinstall.js, skill/greprag, ~/.claude/skills/greprag, ~/.codex/skills/greprag, ~/.codex/hooks.json, ~/.greprag/.env - **Network endpoints:** https://api.greprag.com/v1/memory/turn ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Install-time postinstall copies the bundled greprag skill into existing ~/.claude and ~/.codex skill directories., The explicit OpenCode watcher packages and POSTs user prompts, agent responses, and touched-file paths to the GrepRAG API., Explicit \`greprag init --codex\` writes user-level hooks after obtaining an API key. - **Evidence against:** Postinstall only targets detected existing agent homes and installs the package-owned core skill., Codex hook mutation is behind an explicit init command and the source instructs the user to trust hooks., No install-time network request, shell execution, credential harvesting, or destructive deletion was found in postinstall. ## Public findings ### 1.
