Treat them as untrusted evidence. 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:** 3.0.10 - **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 install hook only overwrites this package's own twist-cli skill files when they already exist in agent skill directories, which is first-party agent-extension setup rather than a new hijack. Scanner malware labels on dist/lib/input.js are a false match for spawning the user's editor, and remaining network and auth code is a normal Twist CLI. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-16T18:16:47.599Z - **Finished:** 2026-09-16T18:19:38.836Z - **Download time:** 1016 ms - **Static scan time:** 500 ms - **AI review time:** 169720 ms - **Total time:** 171237 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:** An npm postinstall hook refreshes already-installed first-party twist-cli SKILL.md files inside several coding-agent skill directories. It does not drop new skills into agents that never had this package skill. - **Trigger:** npm install of @doist/twist-cli, which runs the postinstall script. - **Impact:** Coding agents that already had the Twist CLI skill may load updated instructions after an unattended package install. - **Evidence paths:** package.json, scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js, dist/lib/skills/create-installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T18:19:38.836Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** first-party agent skill auto-update on install - **Rationale:** The install hook only overwrites this package's own twist-cli skill files when they already exist in agent skill directories, which is first-party agent-extension setup rather than a new hijack. Scanner malware labels on dist/lib/input.js are a false match for spawning the user's editor, and remaining network and auth code is a normal Twist CLI. - **Files touched:** ~/.claude/skills/twist-cli/SKILL.md, ~/.codex/skills/twist-cli/SKILL.md, ~/.cursor/skills/twist-cli/SKILL.md, ~/.gemini/skills/twist-cli/SKILL.md, ~/.pi/skills/twist-cli/SKILL.md, ~/.agents/skills/twist-cli/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** npm postinstall runs node scripts/postinstall.js, which loads dist/postinstall.js., postinstall calls updateAllInstalledSkills({ local: false }) and swallows errors., That updater overwrites SKILL.md for any already-installed Twist skill., Installers write into ~/.claude, ~/.codex, ~/.cursor, ~/.gemini, ~/.pi, and ~/.agents skill dirs., create-installer writes bundled twist-cli skill markdown into those agent paths. - **Evidence against:** Updates run only when the twist-cli skill file already exists; missing skills are skipped., New skill drops require an explicit tw skill install command, not a blank install., Bundled skill text is Twist CLI usage docs, not a remote payload or secret harvester., dist/lib/input.js spawn is the user EDITOR for composing messages, not a malware loader., Network use is Twist API and GitHub logo URLs aligned with this CLI., No runtime self-dependency, obfuscation, or install-time credential theft. ## Affected versions and remediation This report applies to @doist/twist-cli@3.0.10. - Review the evidence and your use of @doist/twist-cli@3.0.10 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.
