The package gains automatic execution in the consumer's Claude Code tool workflow without an explicit setup command. - **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:** 0.18.18 - **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. LPM flags this version as an AI-agent control-surface risk. Installation silently modifies the consumer project's Claude Code hook configuration. The added wildcard hook executes this package's handler before tool use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T00:25:07.224Z - **Finished:** 2026-09-13T00:25:57.099Z - **Download time:** 1270 ms - **Static scan time:** 2649 ms - **AI review time:** 45955 ms - **Total time:** 49875 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:** Installation silently modifies the consumer project's Claude Code hook configuration. The added wildcard hook executes this package's handler before tool use. - **Trigger:** npm installation of the package - **Impact:** The package gains automatic execution in the consumer's Claude Code tool workflow without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T00:25:57.099Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall registration of a wildcard Claude PreToolUse command hook - **Attack narrative:** During npm installation, the lifecycle script locates the consumer project, creates .claude if needed, and merges a PreToolUse hook into hooks.json. The hook matches every tool call and runs the package's pre-tool-use handler. This is an unconsented install-time mutation of a foreign AI-agent control surface, creating persistent automatic execution after installation. - **Rationale:** The automatic postinstall hook writes a wildcard command into the consumer's Claude Code configuration. This meets the policy for malicious install-hook abuse even without proven secret theft. - **Files touched:** package.json, scripts/postinstall.js, .claude/hooks.json, dist/hooks/pre-tool-use.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically., The script creates or modifies the consumer project's .claude/hooks.json., It registers its own command as a PreToolUse hook for every matched Claude tool call. - **Evidence against:** No runtime dependency on this package's own name was found., The inspected installer contains no external network endpoint. ## Affected versions and remediation This report applies to @devflow-tools/devflow@0.18.18. - Avoid installing @devflow-tools/devflow@0.18.18. 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.
