The seeded workflow can later publish using the consumer's configured NPM secret. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-09T17:14:34.331Z - **Finished:** 2026-08-09T17:15:10.195Z - **Download time:** 506 ms - **Static scan time:** 95 ms - **AI review time:** 35261 ms - **Total time:** 35864 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code mutates the consuming repository by adding config, CI workflows, and release tooling when absent. The seeded workflow can later publish using the consumer's configured NPM secret. - **Trigger:** npm install, npm ci, or npm update executing postinstall - **Impact:** Adds a release pipeline with repository-write and npm-publish capability to projects that lack those files. - **Evidence paths:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T17:15:10.195Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic consumer-project scaffolding and GitHub Actions workflow seeding - **Rationale:** Source shows a disclosed but unusually invasive postinstall hook that seeds privileged CI release infrastructure. It is not concrete malware, but warrants a warning because installation mutates downstream repositories and can introduce publish-capable automation. - **Files touched:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, .github/workflows/release.yml, .github/workflows/verify-npm-token.yml, .changeset/config.json, scripts/auto-changeset.sh - **Network endpoints:** https://registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs src/postinstall.js automatically., src/postinstall.js seeds .github workflows and release scripts into the consumer project., Seeded release.yml has contents: write and publishes with NODE\_AUTH\_TOKEN. - **Evidence against:** README.md explicitly documents the install-time scaffolding., No source exfiltrates files, environment values, or credentials., Existing destination files are not overwritten; drift is warned. ## 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: 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:** 0.1.19 - **License:** MIT - **Version published:** 2026-08-09T09:14:25.061Z - **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:** 5,241,108 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
