scanned 12d ago · by lpm-firewall-ai

The package automatically modifies the installed Claude Agent SDK CLI to disable a reminder, creating an install-time agent lifecycle risk. The narrow version and content checks reduce scope, so the evidence supports a warning rather than a publish block.

Static reason

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

Trigger

Installing the package through npm triggers its postinstall script.

Impact

The SDK CLI reminder is disabled for the patched installation; no broader agent configuration write or data transfer was established.

Mechanism

The script finds the installed SDK, checks its version and expected patch context, then replaces text in the SDK's cli.js file.

AI rationale

Evidence

package.jsonscripts/postinstall.mjs

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.mjs automatically after install.
The postinstall locates the installed Claude Agent SDK CLI and applies a patch to its cli.js file.
The patch is conditional on matching the expected source text, then writes the replacement and reports that the reminder was disabled.
The reviewed .claude references are configuration and path setup in the named application files; they do not show a broader agent-control write.

Evidence against

The patch is version-matched, checks the expected source text, and is idempotent.
The examined target locations show .claude path/configuration references, not agent-control mutations.
