No malicious install hook or confirmed credential theft was found, so a block is not justified. The combination of opaque distributed code and intentionally permission-bypassing agent and sudo capabilities is a real unresolved host-control risk.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

A user starts the package and uses the web interface or sends work through the AI bridge.

Impact

A compromised local session or unsafe AI input could lead to host-level actions; no automatic install-time attack or confirmed external exfiltration was found.

Mechanism

Permission-bypassing AI execution and web-mediated sudo command dispatch.

AI rationale

Evidence

claude-bridge/src/claude.jsweb/public/js/app-panels.jsdist/web/setup-api.js

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Distributed runtime files are deliberately obfuscated, preventing transparent inspection of privileged setup logic.
The Claude bridge always launches the local Claude command with permission checks disabled.
The web interface sends user-supplied commands to a sudo execution endpoint.

Evidence against

The manifest has no automatic install lifecycle hook; its only lifecycle entry is prepublishOnly.
No concrete secret exfiltration endpoint or automatic destructive action was established from inspected source.
