The install hook modifies a consumer project by seeding declared build configuration and GitHub workflow templates, but source shows no exfiltration, remote payload, or stealth behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 92.0% - **Started:** 2026-08-09T17:11:12.679Z - **Finished:** 2026-08-09T17:11:57.298Z - **Download time:** 508 ms - **Static scan time:** 93 ms - **AI review time:** 44017 ms - **Total time:** 44619 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The install hook modifies a consumer project by seeding declared build configuration and GitHub workflow templates, but source shows no exfiltration, remote payload, or stealth behavior. - **Trigger:** npm installation runs postinstall; the Playwright command and init scaffolder require explicit user invocation. - **Impact:** Creates absent config, pipeline, and branding files in the installing project; existing target files are skipped. - **Evidence paths:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, src/playwright-install.js, src/init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T17:11:57.298Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** documented build-config and release-workflow scaffolding - **Rationale:** The postinstall hook is intrusive but transparently implements this configuration package's documented purpose, copying only fixed local templates and preserving existing files. No concrete malicious chain was found by source inspection. - **Files touched:** package.json, tsconfig.json, tsconfig.test.json, tsconfig.eslint.json, eslint.config.js, prettier.config.js, .github/workflows/release.yml, .github/workflows/verify-npm-token.yml, .changeset/config.json, scripts/auto-changeset.sh, docs/assets/doikayt-logo.png, docs/assets/doikayt-logo.svg - **Network endpoints:** https://registry.npmjs.org ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** package.json postinstall is documented configuration seeding., src/postinstall.js copies only named templates into the consumer project and skips existing files., src/pipeline/release.yml uses the npm registry only for a conventional Changesets release workflow., src/playwright-install.js runs Playwright only when its explicit bin is invoked., No source reads secrets for export, sends arbitrary network requests, or loads remote code. ## 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.

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 src/postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 7. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** src/pipeline/auto-changeset.sh - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```shell path = src/pipeline/auto-changeset.sh kind = build_helper sizeBytes = 2940 magicHex = [redacted] ``` ### 8. High: Ships High Entropy Blob - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** assets/jews-support-a-free-palestine-poster.pdf - **Public source:** [View source]() Package ships high-entropy non-source blobs. Public source snippet (untrusted): ```text path = assets/jews-support-a-free-palestine-poster.pdf kind = high_entropy_blob sizeBytes = 1040003 magicHex = [redacted] ``` ### 9. 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 - **Dependencies:** 4 - **Optional dependencies:** 0 - **Peer dependencies:** 3 - **Development dependencies:** 3 - **Published dependency-graph edges:** 7 ### Published dependency entries - @typescript-eslint/eslint-plugin ^8.0.0 (Dependency) - @typescript-eslint/parser ^8.0.0 (Dependency) - eslint ^9.0.0 (Dependency) - prettier ^3.0.0 (Dependency) - @playwright/test \>=1.40.0 (PeerDependency) - @typescript-eslint/eslint-plugin ^8.57.1 (PeerDependency) - @typescript-eslint/parser ^8.57.1 (PeerDependency) ## Package metadata - **Package:** @doikayt/typescript-build-config - **Ecosystem:** npm - **Version:** 0.1.18 - **License:** MIT - **Version published:** 2026-08-09T08:13:24.827Z - **Package first seen:** 2026-07-27T08:18:40.166Z - **Package last seen:** 2026-08-11T10:03:54.840Z - **Known versions:** 13 - **Latest version:** 0.1.31 - **Appeal under review:** No - **Description:** Shared build configuration for TypeScript projects — ESLint, Prettier, tsconfig, and Playwright presets - **Maintainers:** datalackey - **Keywords:** eslint, typescript, config, build, tooling, playwright - **Runtime engines:** node: \>=22 - **Artifact files:** 40 - **Artifact unpacked size:** 5,240,715 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
