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:** 3.0.9 - **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 package has a real unconsented install-time AI-agent extension update surface, but it is scoped to pre-existing package-named skill files and contains no demonstrated remote payload, self-dependency, or exfiltration chain. This warrants a warning rather than a publication block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-14T03:23:47.752Z - **Finished:** 2026-09-14T03:24:45.761Z - **Download time:** 510 ms - **Static scan time:** 525 ms - **AI review time:** 56973 ms - **Total time:** 58009 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:** npm postinstall overwrites existing Twist CLI skill files inside multiple AI-agent configuration directories. The overwrite is local and package-contained, but occurs without an explicit CLI command during installation. - **Trigger:** Installing the package with lifecycle scripts enabled, after a Twist CLI skill already exists. - **Impact:** Can silently change instructions and capabilities available to configured AI agents. - **Evidence paths:** package.json, 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:** 2026-09-14T03:24:45.761Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic lifecycle update of existing agent skill files. - **Rationale:** The package has a real unconsented install-time AI-agent extension update surface, but it is scoped to pre-existing package-named skill files and contains no demonstrated remote payload, self-dependency, or exfiltration chain. This warrants a warning rather than a publication block. - **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:** Low - **Evidence for warning:** Installation runs a postinstall script., The postinstall silently updates every previously installed agent skill., The updater targets Claude, Codex, Cursor, Gemini, Pi, and a universal agent directory., Skill updates overwrite SKILL.md in home-directory agent configuration paths. - **Evidence against:** Updates are limited to an already-existing twist-cli skill file; they do not create a new foreign agent directory., The embedded skill content is local package data, with no remote payload retrieval., No self-dependency, obfuscation, credential exfiltration, or install-time shell/network execution was found., The flagged editor process runs only when a user invokes the CLI editor flow. ## Affected versions and remediation This report applies to @doist/twist-cli@3.0.9. - Review the evidence and your use of @doist/twist-cli@3.0.9 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.
