Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 2.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall hook writes a package-owned skill into agent skill directories and removes a named superseded skill, which warrants a lifecycle risk warning. The inspected code does not establish a broader agent control-surface attack or credential exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-09T10:14:15.451Z - **Finished:** 2026-10-09T10:15:00.065Z - **Download time:** 510 ms - **Static scan time:** 583 ms - **AI review time:** 43519 ms - **Total time:** 44614 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The automatic postinstall hook replaces this package’s skill in Codex and Claude skill directories and removes a named superseded skill directory. This is a first-party agent extension setup lifecycle risk; the inspected code does not establish a broader control-surface attack. - **Trigger:** Installing the published npm package runs its postinstall hook. - **Impact:** Agent behavior may change when it reads the refreshed package-owned skill; the installer also deletes the specifically named superseded skill directory. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/setup.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:15:00.065Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook imports the bundled setup module, which removes the existing recess-cli skill directory and copies the package’s bundled skill into Codex and Claude skill locations. - **Rationale:** The automatic postinstall hook writes a package-owned skill into agent skill directories and removes a named superseded skill, which warrants a lifecycle risk warning. The inspected code does not establish a broader agent control-surface attack or credential exfiltration. - **Files touched:** ~/.codex/skills/recess-cli, ~/.claude/skills/recess-cli, ~/.codex/skills/recess-admin, ~/.claude/skills/recess-admin ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall hook automatically., The hook imports the packaged setup module and installs a skill during published-package installs., The installer targets Codex and Claude skill directories, removes the existing recess-cli skill directory, and copies in the bundled skill., The installer also removes a specifically named superseded skill directory. - **Evidence against:** The reviewed authentication flow sends its sign-in assertion to the Recess API origin configured for the CLI. ## Affected versions and remediation This report applies to recess-cli@2.0.0. - Review the evidence and your use of recess-cli@2.0.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
