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:** 3.0.13 - **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. Automatic mutation of pre-existing AI-agent skill files is a guarded first-party extension lifecycle risk. The inspected code does not establish a concrete malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-28T04:33:15.724Z - **Finished:** 2026-09-28T04:34:15.678Z - **Download time:** 1017 ms - **Static scan time:** 591 ms - **AI review time:** 58346 ms - **Total time:** 59954 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:** Installation can update existing Twist CLI skills under supported AI-agent directories. No confirmed credential theft, remote payload execution, or broad control-surface takeover was identified. - **Trigger:** npm post-install execution. - **Impact:** Existing first-party Twist CLI agent skills may change automatically during package installation. - **Review source:** ai\_review - **Reviewed:** 2026-09-28T04:34:15.678Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The post-install module enumerates configured skill installers, detects existing skill files, and overwrites those package-owned files. - **Rationale:** Automatic mutation of pre-existing AI-agent skill files is a guarded first-party extension lifecycle risk. The inspected code does not establish a concrete malicious attack. - **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:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package declares an automatic post-install script., The post-install path updates every detected installed skill in the user scope., Skill installation resolves agent skill paths from the home directory and writes the package-owned skill content., The only child process found opens the user-selected editor for interactive input. - **Evidence against:** The skill updater skips agents whose Twist CLI skill is absent., No arbitrary shell execution, evaluator, or unrelated network destination was found in the inspected paths. ## Affected versions and remediation This report applies to @doist/twist-cli@3.0.13. - Review the evidence and your use of @doist/twist-cli@3.0.13 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.
