AI Security Review

scanned 6d ago · by lpm-firewall-ai

The lifecycle behavior is a guarded, first-party agent integration setup, not evidence of credential theft or remote code execution. Because it automatically changes global agent configuration and enables later hook execution, residual lifecycle risk warrants a warning.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installing the package globally with npm, or running its postinstall with --machine-setup.

Impact

Future agent sessions may invoke Twing hooks automatically across repositories on the machine.

Mechanism

The lifecycle hook imports machine setup, which writes a Claude resolver and installs OpenCode and Codex integrations in user-level agent configuration locations.

AI rationale

Evidence

package.jsonpostinstall.cjsdist/machine-setup.jsdist/resolve-hook.jsdist/opencode-plugin.jsdist/codex-hooks.js~/.claude/settings.json~/.config/opencode/plugins/twing.js~/.codex/config.toml

Decision evidence

public snapshot

AI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs machine setup for global installs or when explicitly passed the machine-setup flag.
Machine setup wires Claude, OpenCode, and Codex integrations and marks the installation as managed.
The setup writes a persistent Claude resolver, an OpenCode plugin loader, and Codex hook configuration; these integrations can run in later agent sessions.

Evidence against

Ordinary project installs exit before machine setup; Node version is also checked before loading setup.
The integrations are first-party Twing components, and the source describes the global install as deliberate machine setup.
