A guarded postinstall configures this package's agent extension across Claude, Codex, OpenCode, and Copilot. It injects a local bootstrap at agent session start. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-07-23T09:34:36.690Z - **Finished:** 2026-07-23T09:35:09.935Z - **Download time:** 758 ms - **Static scan time:** 679 ms - **AI review time:** 31807 ms - **Total time:** 33245 ms ## Security analysis ### Published attack-surface review - **Summary:** A guarded postinstall configures this package's agent extension across Claude, Codex, OpenCode, and Copilot. It injects a local bootstrap at agent session start. - **Trigger:** Global npm installation or USE\_CASES\_INSTALL\_AGENT\_HOOKS/AGENT\_HOOKS\_INSTALL opt-in - **Impact:** Agent sessions receive package-provided workflow instructions; no exfiltration or remote payload was confirmed. - **Evidence paths:** package.json, scripts/install-agent-hooks.mjs, hooks/session-start, .opencode/plugin/use-cases.js, bootstrap/use-cases.md, packages/mcp/dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-23T09:35:09.935Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded first-party agent hook and plugin registration - **Rationale:** The package has a real guarded install-time agent-extension surface, requiring a warning under policy. Source inspection found no concrete malicious chain. - **Files touched:** scripts/install-agent-hooks.mjs, hooks/session-start, bootstrap/use-cases.md, ~/.claude/settings.json, ~/.codex/hooks.json, ~/.config/opencode/opencode.json, ~/.copilot/hooks/use-cases.json ### 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 postinstall hook, install-agent-hooks.mjs registers session hooks for four agent hosts, Global install or explicit env opt-in enables config mutation, Session hook injects packaged bootstrap into agent context - **Evidence against:** Hook exits for ordinary local installs unless opt-in env is set, All injected content is local package bootstrap, No outbound network or credential-exfiltration code found, MCP server uses local stdio and bundled-core fallback ## Public findings ### 1.
