thalamus@1.5.56
⚠ Under reviewMobile and Web client for Claude Code
AI Security Review
scanned 22d ago · by lpm-firewall-aiThe inspected flagged agent code reads settings and transcript paths without establishing agent control-surface mutation. The install hook executes archive extraction, but the required binary archive remains unresolved, so manual review is appropriate.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
npm postinstall.
Impact
The archive contents and behavior remain unresolved, so a clean verdict is not supported; no attack was confirmed.
Mechanism
The hook selects platform-specific archives, extracts them into the package tools directory, and sets executable permissions on extracted files.
AI rationale
The inspected flagged agent code reads settings and transcript paths without establishing agent control-surface mutation. The install hook executes archive extraction, but the required binary archive remains unresolved, so manual review is appropriate.

Decision evidence
public snapshotAI called this Manual Review at 93.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The postinstall hook runs the unpacker, which extracts platform-specific archives into the tools directory and gives extracted files executable permissions.
- The flagged agent-related code reads Claude settings to check memory directory overrides and resolves transcript files under the Claude projects directory; the inspected excerpts establish no control-surface mutation.
