Feishu-first personal AI assistant powered by local Agents.

AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installation fetches a remote platform executable, then invokes it to install Codex and Claude Code hooks plus Skills without a user command. This mutates foreign AI-agent control surfaces at npm postinstall.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm postinstall

Impact

The fetched executable can alter Codex and Claude Code completion behavior and install Skills during package installation.

Mechanism

remote binary download followed by automatic AI-agent hook installation

Policy narrative

The postinstall script downloads a platform binary from release hosts into vendor/ and executes it with --install-agent-hooks. The package documentation states that this installs Codex notify and Claude Code Stop hooks and a Feishu-context Skill for both agents. This is an unconsented install-time mutation of third-party AI-agent control surfaces, implemented through an unverified remote executable.

Rationale

The package performs automatic postinstall setup of Codex and Claude Code hooks through a remotely downloaded executable. That meets the install-time foreign AI-agent control-surface mutation block boundary.
