Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Automatic installation modifies the consuming project's Claude control configuration. The added wildcard command hook runs the package handler for every PreToolUse event. - **Trigger:** npm installation runs the postinstall lifecycle script. - **Impact:** The package gains automatic execution in a broad AI-agent tool-use control surface without an explicit user command or consent. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-20T03:05:09.726Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script creates .claude, merges a wildcard PreToolUse command entry, and writes .claude/hooks.json in the consumer project. - **Attack narrative:** On installation, the package discovers the consumer project and writes a Claude hooks configuration. It installs a wildcard PreToolUse command pointing to its bundled handler, causing package code to execute on every Claude tool call. This is an unconsented postinstall mutation of a broad foreign AI-agent control surface. - **Rationale:** The automatic postinstall hook persists a wildcard command into the consumer's Claude configuration. This meets the install-time AI-agent control-surface abuse blocking policy. - **Files touched:** .claude/hooks.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a package script automatically after installation., The install script locates the consumer project and creates its .claude directory., It registers a command hook with a wildcard matcher for every Claude PreToolUse event., It writes the merged hook configuration into the consumer project's .claude/hooks.json. ## Affected versions and remediation This report applies to @devflow-tools/devflow@0.18.24. - Avoid installing @devflow-tools/devflow@0.18.24. 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.
