@twing/cli@1.1.0

AI Security Review

scanned 11d ago · by lpm-firewall-ai

Inspected source shows an install-time machine setup gate and agent integration, but no concrete malicious behavior. The findings are consistent with guarded setup of this package’s own hooks, so mark clean.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Global npm installation or explicit `--machine-setup`; repository and machine wiring can also follow explicit initialization.

Impact

Twing’s hooks can run in agent sessions and coordinate with Twing services; the inspected evidence does not establish credential theft or hostile control.

Mechanism

The postinstall gate invokes machine setup, which writes agent configuration and installs Twing’s resolver/plugin integration.

Decision evidence

public snapshot

AI called this Clean at 73.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json runs `node postinstall.cjs`; the hook exits unless npm reports a global install or an explicit machine-setup flag.
Machine setup wires Claude Code and OpenCode settings and writes an auto-managed marker; this is broad machine-level agent integration.
The flagged target files describe committed repo hooks, explicit `twing init`, and primary-working-directory resolution; their cited passages are descriptive comments.
The adapter resolves and runs a configured Twing hook, while test-support’s child process runs `git init` in a temporary test repository.
No concrete credential theft, unrelated recipient, destructive action, or concealed payload execution was established from the inspected source.

Evidence against

The postinstall gate excludes ordinary project installs and self-installs unless the machine-setup flag is passed.
The inspected adapter, test-support, and SQLite-source excerpts do not establish hostile execution; machine integration appears to install Twing’s own hook/plugin.
