Installing the package executes a postinstall updater that rewrites already-present Twist skills in supported agent directories. The content is bundled, but the mutation is silent and occurs outside the package directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-24T04:35:26.528Z - **Finished:** 2026-08-24T04:36:21.482Z - **Download time:** 759 ms - **Static scan time:** 668 ms - **AI review time:** 53526 ms - **Total time:** 54954 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package executes a postinstall updater that rewrites already-present Twist skills in supported agent directories. The content is bundled, but the mutation is silent and occurs outside the package directory. - **Trigger:** npm install, unless lifecycle scripts are disabled - **Impact:** Changes agent-readable Twist CLI instructions in existing .claude, .codex, .cursor, .gemini, .pi, or .agents installations. - **Evidence paths:** package.json, scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/index.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/content.js - **Review source:** ai\_review - **Reviewed:** 2026-08-24T04:36:21.482Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall updates pre-existing AI-agent skill files - **Rationale:** The package silently mutates existing AI-agent extension files during npm postinstall, a real but scoped lifecycle risk. Inspected code uses bundled content and shows no concrete payload delivery or credential exfiltration. - **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:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall silently invokes a global installed-skill updater., Updater rewrites existing Twist skill files under multiple AI-agent directories, including .codex and .agents. - **Evidence against:** Updates are limited to an existing twist-cli skill path and use bundled static content., No remote payload download or credential exfiltration was found in inspected lifecycle and skill code. ## Public findings ### 1.

Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** dist/lib/skills/create-installer.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L24: async install(options) { L25: if (!options.local && config.dirName !== '.agents') { L26: const agentDir = join(homedir(), config.dirName); ... L38: } L39: await mkdir(dirname(skillPath), { recursive: true }); L40: await writeFile(skillPath, SKILL_FILE_CONTENT); ``` ### 10. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 11. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 12. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, prepublishOnly - **Dependencies:** 9 - **Optional dependencies:** 1 - **Peer dependencies:** 0 - **Development dependencies:** 11 - **Published dependency-graph edges:** 10 ### Published dependency entries - @doist/cli-core 0.26.2 (Dependency) - @doist/twist-sdk 2.9.4 (Dependency) - @pnpm/tabtab 0.5.4 (Dependency) - chalk 5.6.2 (Dependency) - commander 14.0.3 (Dependency) - marked 18.0.10 (Dependency) - marked-terminal-renderer 2.2.0 (Dependency) - oauth4webapi 3.8.7 (Dependency) - open 11.0.1 (Dependency) - @napi-rs/keyring 1.3.0 (OptionalDependency) ## Package metadata - **Package:** @doist/twist-cli - **Ecosystem:** npm - **Version:** 3.0.5 - **License:** MIT - **Version published:** 2026-08-24T04:30:39.792Z - **Package first seen:** 2026-07-07T23:38:21.866Z - **Package last seen:** 2026-09-04T04:13:23.896Z - **Known versions:** 6 - **Latest version:** 3.0.7 - **Appeal under review:** No - **Description:** TypeScript CLI for Twist - **Author:** Ernesto García - **Maintainers:** ricardoist, henningmu, jvalente, antondoist, jefcurtis, dmgawel, doistbot, fbidu, goncalossilva, omar.doist.com, scottatdoist, craigcarlyle - **Keywords:** twist, cli, messaging, doist - **Runtime engines:** npm: \>=11, node: \>=24 - **Artifact files:** 474 - **Artifact unpacked size:** 877,359 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
