It removes and copies only the package-named skill, which broadens Claude guidance for Astro component requests. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-26T00:02:43.967Z - **Finished:** 2026-08-26T00:03:43.578Z - **Download time:** 752 ms - **Static scan time:** 1911 ms - **AI review time:** 56948 ms - **Total time:** 59611 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall modifies the consuming project's Claude skills directory. It removes and copies only the package-named skill, which broadens Claude guidance for Astro component requests. - **Trigger:** npm installation - **Impact:** Unconsented project AI-agent configuration mutation; no exfiltration or remote execution confirmed. - **Evidence paths:** package.json, postinstall.mjs, agents/claude/evoke-astro-core/SKILL.md, src/components/PdfViewer/PdfViewer.ts, src/integrations/relative-links.ts, src/integrations/prune-build.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-26T00:03:43.578Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic first-party Claude skill replacement - **Rationale:** Source confirms automatic AI-agent skill mutation during install. Its package-scoped destination and documentation-only content support a warning rather than a malicious block. - **Files touched:** postinstall.mjs, agents/claude/evoke-astro-core/SKILL.md, .claude/skills/evoke-astro-core ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs postinstall.mjs automatically on installation., postinstall deletes and replaces .claude/skills/evoke-astro-core in the consuming project., The installed skill directs Claude to activate for broad Astro component requests. - **Evidence against:** The mutation is limited to a package-named skill directory copied from the package., No credential harvesting, shell execution, remote payload loading, or network exfiltration was found in reviewed source., Bundled PDF code is used by the PDF viewer to load the caller-supplied data-pdf URL. ## Public findings ### 1.
