It targets global home-directory agent configuration rather than the installed package. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** It can change instructions available to Codex, Claude Code, Cursor, Gemini, Pi, and universal agents without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T04:13:23.896Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global overwrite of detected agent skill files. - **Attack narrative:** On installation, the manifest launches scripts/postinstall.js, which imports dist/postinstall.js. That code scans configured agent skill locations in the user home directory and overwrites each existing Twist CLI skill file with package-supplied content. The targets span several unrelated AI-agent control surfaces and the update runs automatically, without an explicit skill-install command or confirmation. - **Rationale:** This is an unconsented npm postinstall mutation of broad foreign AI-agent control surfaces. The existing-file guard limits scope but does not establish user consent for automatic overwrites. - **Files touched:** scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/index.js, ~/.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:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script automatically during npm installation., The postinstall loader imports the installed code without a user command., Installed code updates every detected agent skill globally., The updater overwrites skill files under several foreign AI-agent directories, including Codex and Claude Code. - **Evidence against:** Updates occur only when the target skill file already exists., The skill content is bundled locally rather than downloaded at install time., No self-dependency or arbitrary shell execution was found. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.js ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** scripts/check-skill-sync.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L17: const modulePath = pathToFileURL(join(root, 'dist/lib/skills/content.js')).href L18: const { SKILL_FILE_CONTENT } = await import(modulePath) L19: const expected = SKILL_FILE_CONTENT ``` ### 6. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 7. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 8. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 9. 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. ### 13. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** package.json - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```json stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1 ``` ## 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 18.0.11 (Dependency) - marked-terminal-renderer 2.2.0 (Dependency) - oauth4webapi 3.8.7 (Dependency) - open 11.0.2 (Dependency) - @napi-rs/keyring 1.3.0 (OptionalDependency) ## Package metadata - **Package:** @doist/twist-cli - **Ecosystem:** npm - **Version:** 3.0.7 - **License:** MIT - **Version published:** 2026-09-04T04:10:00.749Z - **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 - **Keywords:** twist, cli, messaging, doist - **Runtime engines:** npm: \>=11, node: \>=24 - **Artifact files:** 474 - **Artifact unpacked size:** 877,960 bytes - **Artifact signatures:** 2 - **Attestations:** Yes ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
