The package changes files that guide AI agent behavior in the consuming project. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.5.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package has an automatic postinstall that mutates a consumer project's AI-agent instruction surface without an explicit consent gate. This meets the policy for unconsented postinstall mutation of a foreign AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-11T16:57:10.509Z - **Finished:** 2026-10-11T16:57:50.487Z - **Download time:** 776 ms - **Static scan time:** 36 ms - **AI review time:** 39165 ms - **Total time:** 39978 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 automatic postinstall writes package-provided skills into the consumer's Claude configuration and inserts behavior-bearing instructions into a consumer agent instruction file. - **Trigger:** npm install runs the package's postinstall hook. - **Impact:** The package changes files that guide AI agent behavior in the consuming project. - **Evidence paths:** package.json, scripts/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-11T16:57:50.487Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies skills into .claude/skills and adds a managed rules block to AGENTS.md or, when appropriate, CLAUDE.md without an explicit consent check. - **Attack narrative:** During npm installation, the postinstall hook invokes the installer. It copies shipped skill content into the consumer project's Claude skills directory and writes rules into an agent instruction file. No source-level consent prompt or opt-in gate precedes these writes. - **Rationale:** The package has an automatic postinstall that mutates a consumer project's AI-agent instruction surface without an explicit consent gate. This meets the policy for unconsented postinstall mutation of a foreign AI-agent control surface. - **Files touched:** package.json, scripts/install.mjs, scripts/uninstall.mjs, .claude/skills/, AGENTS.md, CLAUDE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/install.mjs automatically during postinstall., The installer copies package skills into the consumer project's .claude/skills directory., The installer injects package rules into the consumer's AGENTS.md or CLAUDE.md without a consent gate., The install routine runs when the postinstall command invokes the installer. - **Evidence against:** The installer skips existing skill folders that are not recorded as managed by this package., The uninstall script removes only recorded skills and managed blocks from listed files. ## Affected versions and remediation This report applies to @softure-ai/skills@0.5.0. - Avoid installing @softure-ai/skills@0.5.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
