Claude Code in the consuming project starts executing package-controlled PreToolUse logic on every tool call, including permission deny and prompt-context injection. - **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:** 0.18.23 - **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. On npm install, postinstall silently merges a PreToolUse matcher \* command into the consumer project's .claude/hooks.json. That command runs this package's hook, which can deny Claude tool calls and inject extra agent context. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-18T15:57:14.709Z - **Finished:** 2026-09-18T15:59:44.951Z - **Download time:** 1035 ms - **Static scan time:** 3265 ms - **AI review time:** 145941 ms - **Total time:** 150242 ms The recorded confidence comes from the underlying analysis.

That command runs this package's hook, which can deny Claude tool calls and inject extra agent context. - **Trigger:** npm install of @devflow-tools/devflow, which runs the postinstall script with no user confirmation. - **Impact:** Claude Code in the consuming project starts executing package-controlled PreToolUse logic on every tool call, including permission deny and prompt-context injection. - **Evidence paths:** package.json, scripts/postinstall.js, dist/hooks/pre-tool-use.js - **Review source:** ai\_review - **Reviewed:** 2026-09-18T15:59:44.951Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented install-time write of a foreign Claude Code project hook - **Attack narrative:** Installing this package runs postinstall, which finds the consumer project and writes Claude Code's .claude/hooks.json. It registers a PreToolUse hook with matcher \* that executes dist/hooks/pre-tool-use.js. After that, Claude tool use in the project is gated by DevFlow code that can deny tools and inject additionalContext. This is not limited to the package's own plugin directory and does not wait for a user command such as devflow init. - **Rationale:** Source shows an unconsented npm postinstall write into Claude Code's project hooks.json with a wildcard PreToolUse command. That is a foreign, broad agent control-surface mutation and meets publish\_block for ai\_agent\_control\_hijack. - **Files touched:** scripts/postinstall.js, dist/hooks/pre-tool-use.js, .claude/hooks.json, .claude ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/postinstall.js automatically on npm install with no opt-in flag., postinstall walks to the consumer project root, creates .claude, and writes .claude/hooks.json., The written hook is PreToolUse with matcher \* running node dist/hooks/pre-tool-use.js on every Claude tool call., The registered hook can deny tool use and inject additionalContext into Claude Code., README only documents install plus a later devflow init command and does not describe this automatic Claude hook write. - **Evidence against:** The package also ships a first-party DevFlow Claude plugin under dist/plugin and a user-invoked CLI setup path., Hook HTTP goes to a local DevFlow runtime URL or DEVFLOW\_SERVER\_URL, not a hidden third-party host., There is no runtime self-dependency on this package name. ## Affected versions and remediation This report applies to @devflow-tools/devflow@0.18.23. - Avoid installing @devflow-tools/devflow@0.18.23. 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.
