Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook performs automatic user-level agent skill setup, but the copied skill is package-owned and no broader agent configuration mutation or network transfer was identified. This fits a warning for agent extension lifecycle risk, not a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-12T16:53:33.460Z - **Finished:** 2026-10-12T16:54:39.283Z - **Download time:** 1025 ms - **Static scan time:** 907 ms - **AI review time:** 63890 ms - **Total time:** 65823 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The npm postinstall hook copies this package’s bundled skill into the user-level Claude skills directory. This is automatic package-owned agent skill setup, which warrants a warning. - **Trigger:** Installation of the package runs its postinstall hook. - **Impact:** The package’s CLI skill becomes available in the user’s Claude environment without a separate setup command. - **Evidence paths:** package.json, skillit-postinstall.cjs, skills/lsproxy-cli/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-10-12T16:54:39.283Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies each bundled skill directory under the user’s Claude skills directory and rewrites the installed copy. - **Rationale:** The postinstall hook performs automatic user-level agent skill setup, but the copied skill is package-owned and no broader agent configuration mutation or network transfer was identified. This fits a warning for agent extension lifecycle risk, not a publish block. - **Files touched:** ~/.claude/skills/lsproxy-cli ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs skillit-postinstall.cjs automatically after installation., The hook copies bundled skill directories into the user-level Claude skills directory without a consent prompt., The installed skill describes this package’s LSP refactoring CLI., Claude plugin settings changes are exposed through the explicit config export command; the adapter enables matching installed plugins., The Claude adapter targets the user’s Claude settings file. - **Evidence against:** The install hook copies package-bundled skills; inspected source showed no unrelated configuration write or network transfer. ## Affected versions and remediation This report applies to @lsproxy/cli@1.1.0. - Review the evidence and your use of @lsproxy/cli@1.1.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
