On direct installation, the postinstall hook mutates the consuming project’s Claude skill directory and may modify its ESLint config. This is a persistent first-party agent-extension setup, not a confirmed exfiltration or payload chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-09T09:18:35.686Z - **Finished:** 2026-08-09T09:19:21.426Z - **Download time:** 1014 ms - **Static scan time:** 1075 ms - **AI review time:** 43648 ms - **Total time:** 45740 ms ## Security analysis ### Published attack-surface review - **Summary:** On direct installation, the postinstall hook mutates the consuming project’s Claude skill directory and may modify its ESLint config. This is a persistent first-party agent-extension setup, not a confirmed exfiltration or payload chain. - **Trigger:** npm installation of @impakers/debug in a consumer project - **Impact:** Changes AI-agent guidance and project lint configuration without an explicit setup command. - **Evidence paths:** package.json, scripts/setup.mjs, templates/ui-mapping-skill.md, dist/telemetry.mjs, dist/jsx-source-loader.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-09T09:19:21.426Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes a managed Claude skill and injects an ESLint preset - **Rationale:** The package is not proven malicious, but its automatic postinstall mutation of a consumer Claude skill is a concrete lifecycle risk. Per policy, this first-party extension setup warrants a warning rather than a block. - **Files touched:** scripts/setup.mjs, templates/ui-mapping-skill.md, .claude/skills/impakers-ui-mapping/SKILL.md, eslint.config.mjs, eslint.config.js, eslint.config.cjs - **Network endpoints:** https://os.impakers.club/api/external/feedback, https://os.impakers.club/api/external/telemetry ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/setup.mjs via postinstall., scripts/setup.mjs automatically creates consumer .claude/skills/impakers-ui-mapping/SKILL.md., scripts/setup.mjs patches a consumer ESLint flat-config when recognized., The installed skill gives Claude project-specific coding instructions. - **Evidence against:** Setup is scoped to the install root and skips source/link/transitive contexts., Existing unmarked skill files are preserved; managed files use a package marker., No network, credential harvesting, or remote payload execution appears in setup.mjs., Runtime telemetry targets the package-aligned os.impakers.club endpoints and redacts sensitive fields. ## Public findings ### 1.
