Global installation can automatically register this package as a user-level AI-agent extension and inject its bootstrap into future sessions. No concrete exfiltration, remote payload, or destructive chain was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-07-23T08:25:10.577Z - **Finished:** 2026-07-23T08:25:49.400Z - **Download time:** 764 ms - **Static scan time:** 731 ms - **AI review time:** 37327 ms - **Total time:** 38823 ms ## Security analysis ### Published attack-surface review - **Summary:** Global installation can automatically register this package as a user-level AI-agent extension and inject its bootstrap into future sessions. No concrete exfiltration, remote payload, or destructive chain was found. - **Trigger:** Global npm install, or USE\_CASES\_INSTALL\_AGENT\_HOOKS/AGENT\_HOOKS\_INSTALL opt-in - **Impact:** Persistent agent-session instruction injection until configuration is removed. - **Evidence paths:** package.json, scripts/install-agent-hooks.mjs, hooks/session-start, bootstrap/use-cases.md, .opencode/plugin/use-cases.js, packages/mcp/dist/tools.js - **Review source:** ai\_review - **Reviewed:** 2026-07-23T08:25:49.400Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** conditional user-level AI-agent hook and plugin registration - **Rationale:** Source establishes conditional first-party agent extension setup, not a concrete malicious chain. Per policy this warrants a warning rather than a block. - **Files touched:** scripts/install-agent-hooks.mjs, hooks/session-start, bootstrap/use-cases.md, .opencode/plugin/use-cases.js, ~/.claude/settings.json, ~/.codex/hooks.json, ~/.config/opencode/opencode.json, ~/.copilot/hooks/use-cases.json ### 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, install-agent-hooks.mjs conditionally edits user agent configs, postinstall registers SessionStart bootstrap for Claude, Codex, OpenCode, Copilot, bootstrap/use-cases.md injects agent instructions at session start - **Evidence against:** Hook installation is limited to global installs or explicit environment opt-in, Hook payload only reads package-local bootstrap text, No network or credential-exfiltration code found, MCP writes and command execution require explicit server environment flags ## Public findings ### 1.
