AI Security Review

scanned 6d ago · by lpm-firewall-ai

The package automatically patches a dependency's agent CLI to disable a bundled reminder. This unconsented lifecycle mutation of an agent control surface warrants blocking.

Static reason

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

Trigger

Installing the package through a lifecycle-enabled npm install.

Impact

The SDK's runtime behavior is changed without a separate user-invoked setup step.

Mechanism

The hook locates the SDK CLI, applies a shipped patch to its contents, and writes the modified file.

Policy narrative

During package installation, the postinstall hook finds the installed Claude Agent SDK and applies a bundled patch to its CLI. The script identifies the change as disabling a reminder and writes the changed CLI back to the dependency, altering an agent runtime without separate user consent.

AI rationale

The package automatically patches a dependency's agent CLI to disable a bundled reminder. This unconsented lifecycle mutation of an agent control surface warrants blocking.

Evidence

package.jsonscripts/postinstall.mjspatches/@anthropic-ai+claude-agent-sdk+0.2.50.patchnode_modules/@anthropic-ai/claude-agent-sdk/cli.js

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 98.0% confidence with low false-positive risk.

Evidence for policy risk

The package manifest runs scripts/postinstall.mjs automatically and depends on @anthropic-ai/claude-agent-sdk@0.2.50.
The postinstall script resolves the installed SDK and writes a modified cli.js into its directory.
The script reports that its patch disables a reminder, and the shipped patch targets the SDK CLI.

Evidence against

The inspected behavior establishes local SDK modification; it does not establish credential theft or network exfiltration.
