The resulting wildcard PreToolUse hook executes package code on future tool calls. - **Trigger:** Automatic npm postinstall during package installation. - **Impact:** Changes a foreign AI-agent control surface without an explicit user setup command, causing package code to run for every matching tool use. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T13:33:14.186Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Writes a wildcard Claude PreToolUse command hook into the consumer project. - **Attack narrative:** The package's automatic postinstall script walks from the install working directory to locate a consumer project, creates .claude if needed, merges a PreToolUse entry matching every tool call, and writes .claude/hooks.json. That entry executes the package's pre-tool-use handler in future Claude Code sessions. This is an unconsented install-time mutation of a foreign AI-agent control surface. - **Rationale:** Automatic installation persists a wildcard Claude Code command hook in the consumer project. This meets the blocking policy for unconsented postinstall mutation of a broad AI-agent control surface. - **Files touched:** package.json, scripts/postinstall.js, .claude/hooks.json, dist/hooks/pre-tool-use.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs a postinstall script., The install script searches upward for a consumer project root., Installation creates the consumer's .claude directory and targets its hooks configuration., It registers a wildcard command hook that executes the package handler, then writes the merged configuration. - **Evidence against:** The installed hook points to a handler shipped by this package; no unrelated network endpoint is configured by the installer itself. ## Affected versions and remediation This report applies to @devflow-tools/devflow@0.18.6. - Avoid installing @devflow-tools/devflow@0.18.6. 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.
