Install-time setup copies this package's skill into detected Claude/Codex skill directories. Explicit setup registers agent hooks that upload turn data and inject cloud inbox content into agent context. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-07-26T19:08:05.763Z - **Finished:** 2026-07-26T19:08:52.261Z - **Download time:** 503 ms - **Static scan time:** 4795 ms - **AI review time:** 41199 ms - **Total time:** 46498 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time setup copies this package's skill into detected Claude/Codex skill directories. Explicit setup registers agent hooks that upload turn data and inject cloud inbox content into agent context. - **Trigger:** npm install for skill copy; explicit greprag init --codex plus trusted hooks for runtime behavior - **Impact:** A configured user can have prompts, responses, tool summaries, and inbound cloud messages processed by GrepRAG. - **Evidence paths:** package.json, scripts/postinstall.js, dist/commands/init.js, dist/hook.js, dist/codex-steering.js, dist/codex-prompt-cache.js - **Review source:** ai\_review - **Reviewed:** 2026-07-26T19:08:52.261Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** first-party agent skill setup, lifecycle hooks, and authenticated cloud memory/inbox relay - **Rationale:** This is not concrete malware under the install-control policy: automatic installation is limited to a package-owned skill, while hook configuration requires an explicit command and platform trust review. The package still warrants a warning because its configured hooks can relay sensitive agent context and cloud-delivered instructions. - **Files touched:** scripts/postinstall.js, ~/.claude/skills/greprag, ~/.codex/skills/greprag, ~/.codex/hooks.json, ~/.greprag/.env, ~/.greprag/codex/\*.json - **Network endpoints:** https://api.greprag.com/v1/memory/turn, https://api.greprag.com/v1/inbox ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **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 existing ~/.claude/skills and ~/.codex/skills., Explicit greprag init --codex writes ~/.codex/hooks.json with lifecycle hooks., dist/hook.js sends captured prompts, responses, tool summaries, and paths to the API., dist/codex-steering.js injects API inbox messages as Codex additionalContext. - **Evidence against:** Postinstall only installs the package-named skill and does not register hooks or make network calls., Hook registration requires explicit greprag init --codex and documents Codex trust review., Network calls use the configured GrepRAG API key and default to api.greprag.com., Source includes secret scrubbing before memory-turn upload; no credential harvesting or hidden payload execution found. ## Public findings ### 1.
