AI Security Review

scanned 15d ago · by lpm-firewall-ai

The package's devcontainer setup changes Claude Code's user-level settings to bypass permission prompts. This is a dangerous agent capability, while the inspected manifest shows no npm lifecycle trigger to support a publish block.

Static reason

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

Trigger

The configured devcontainer post-create command runs during container creation.

Impact

Claude Code can run without its normal permission prompts in that environment.

Mechanism

The script reads or initializes ~/.claude/settings.json, sets permissions.defaultMode, and writes the file.

AI rationale

Evidence

.devcontainer/devcontainer.json.devcontainer/post-create.sh~/.claude/settings.json

Decision evidence

public snapshot

AI called this Suspicious at 96.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The devcontainer automatically runs its post-create script after setup.
That script writes Claude Code's user-level default mode as bypassPermissions.
The manifest defines package entrypoints and dependencies but no npm lifecycle scripts.

Evidence against

The permission change is tied to the devcontainer's post-create setup, not an npm lifecycle hook.
