The package mutates a consuming project's Claude Code skills during npm install. This is an unconsented AI-agent control surface write, independent of whether the bundled skill text is otherwise benign. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-07-02T19:29:41.289Z - **Finished:** 2026-07-02T19:30:37.066Z - **Download time:** 763 ms - **Static scan time:** 159 ms - **AI review time:** 54854 ms - **Total time:** 55777 ms ## Security analysis ### Published attack-surface review - **Summary:** The package mutates a consuming project's Claude Code skills during npm install. This is an unconsented AI-agent control surface write, independent of whether the bundled skill text is otherwise benign. - **Trigger:** npm install of @xbg.solutions/bpsk-core@2.0.0 - **Impact:** Alters future AI-agent behavior/instructions in the consumer project and overwrites existing skill files. - **Evidence paths:** package.json, scripts/copy-skills.cjs, .claude/skills/skill.md, .claude/skills/firebase/firebase-local-env-setup/SKILL.md, .claude/skills/firebase/cloud-functions/scripts/export\_firestore.sh, .claude/skills/firebase/cloud-functions/scripts/manage\_secrets.sh - **Review source:** ai\_review - **Reviewed:** 2026-07-02T19:30:37.066Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall recursive copy into .claude/skills - **Attack narrative:** On npm install, the postinstall hook runs scripts/copy-skills.cjs. That script derives the consumer project root from INIT\_CWD, then recursively copies the package's .claude/skills directory into \/.claude/skills, overwriting existing files. The installed content is AI-agent instruction material and helper scripts, so package installation changes the user's agent control surface without an explicit user action beyond dependency installation. - **Rationale:** Static inspection confirms lifecycle execution that writes package-supplied Claude Code skills into the consuming project. No exfiltration was found, but the unconsented install-time AI-agent control-surface mutation is concrete attack behavior under the review policy. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** package.json, scripts/copy-skills.cjs, .claude/skills, \/.claude/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs postinstall: node scripts/copy-skills.cjs, scripts/copy-skills.cjs uses INIT\_CWD to locate the consuming project root, scripts/copy-skills.cjs recursively copies package .claude/skills into project .claude/skills, copyDirSync overwrites existing target files with package-supplied skills, Bundled .claude/skills contains many agent instruction files and Firebase/MCP setup guidance - **Evidence against:** lib/index.js is a barrel export for framework utilities, no import-time execution found, No credential harvesting or external exfiltration endpoint found in inspected source, Shell scripts under .claude/skills appear user-invoked Firebase helpers, not lifecycle-executed, Network references are Firebase/local emulator or documentation-oriented ## Public findings ### 1.
