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. Automatic lifecycle mutation of existing AI-agent skill files is a real extension lifecycle risk. It is limited to first-party Twist skill paths and no concrete exfiltration, remote execution, or broad control-surface rewrite was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-22T02:31:50.473Z - **Finished:** 2026-09-22T02:41:06.241Z - **Download time:** 1040 ms - **Static scan time:** 544 ms - **AI review time:** 554183 ms - **Total time:** 555768 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:** On npm installation, the package automatically refreshes existing Twist CLI agent skill files. This is a lifecycle-driven mutation of agent extension files, but no credential exfiltration or remote payload delivery was identified. - **Trigger:** npm runs the package postinstall hook. - **Impact:** Existing Twist CLI skills under supported agent configuration directories can be overwritten during package installation. - **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:** 2026-09-22T02:41:06.241Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook calls the installed-skill updater, which checks agent skill paths and writes package-provided SKILL.md content when a Twist skill already exists. - **Rationale:** Automatic lifecycle mutation of existing AI-agent skill files is a real extension lifecycle risk. It is limited to first-party Twist skill paths and no concrete exfiltration, remote execution, or broad control-surface rewrite was found. - **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:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package declares an automatic postinstall lifecycle hook., The lifecycle script imports the built postinstall module., Postinstall updates every already installed Twist skill without user command invocation., The updater targets configured Claude Code, Codex, Cursor, Gemini, Pi, and universal agent skill locations., The installer overwrites the existing skill file with package-provided content. - **Evidence against:** No network endpoint or credential forwarding was identified in the inspected lifecycle and skill-installation paths., The updater skips agent locations where the Twist skill is not already installed. ## Affected versions and remediation This report applies to @doist/twist-cli@3.0.12. - Review the evidence and your use of @doist/twist-cli@3.0.12 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.
