Changes instructions available to installed AI agents, including broad .agents support. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 3.0.8 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically updates existing skills across several AI-agent control directories. It writes package-controlled skill content without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-11T03:39:33.567Z - **Finished:** 2026-09-11T03:40:39.614Z - **Download time:** 1004 ms - **Static scan time:** 1000 ms - **AI review time:** 64043 ms - **Total time:** 66047 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:** Installing the package automatically updates existing skills across several AI-agent control directories. It writes package-controlled skill content without an explicit user command. - **Trigger:** npm postinstall during package installation - **Impact:** Changes instructions available to installed AI agents, including broad .agents support. - **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:** 2026-09-11T03:40:39.614Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic overwrite of detected agent skill files - **Attack narrative:** When npm installs this package, its postinstall hook loads the compiled installer. That installer scans supported agent directories and overwrites every already-installed Twist skill, including Codex, Claude Code, Cursor, and .agents. The mutation is automatic and occurs outside an explicit skill-management command. - **Rationale:** The postinstall lifecycle performs unconsented mutation of foreign and broad AI-agent control surfaces. This meets the install-hook abuse blocking boundary despite skipping paths where no prior skill exists. - **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:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers a postinstall lifecycle hook., Postinstall imports code that updates all globally installed skills., The update loop overwrites every detected installed skill without a user command., Targeted skill locations include Claude Code, Codex, Cursor, Gemini, Pi, and the broad .agents directory., Skill updates write a package-controlled SKILL.md into those agent control surfaces., The updater overwrites the installed SKILL.md with package-controlled content. - **Evidence against:** The updater skips agent skill paths that are not already present., No relevant network endpoint or remote payload loader was found in the install-time skill-update path., The interactive skill commands expose explicit install, update, and uninstall actions. ## Affected versions and remediation This report applies to @doist/twist-cli@3.0.8. - Avoid installing @doist/twist-cli@3.0.8. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
