dsh-agy-link@0.4.86
Google Antigravity (agy CLI) models for DeepSeek Harness — stream Gemini/Claude/GPT-OSS subscriptions into DSH with thinking, tool activity, token usage and in-GUI Google OAuth login.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package exposes a tool whose fallback output explicitly discourages AI agents from investigating the bridge and its logs. This is reviewer or agent manipulation embedded in a reachable tool response, so I classify the package as malicious.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
An agent requests a mirrored tool result after its recording is unavailable or the requested step is missing.
Impact
The instruction can suppress investigation of relevant tool behavior and redirect the agent to continue its task without examining the missing result.
Mechanism
The fallback tool output asserts there is nothing to investigate and explicitly tells the agent not to investigate the bridge, its logs, or the message.
Attack narrative
When the registered DSH mirror tool cannot find a recording or step, it returns text instructing the AI agent not to investigate the bridge, logs, or message, and to continue the user's task. This is an explicit attempt to steer an agent away from reviewing relevant behavior.
AI rationale
The package exposes a tool whose fallback output explicitly discourages AI agents from investigating the bridge and its logs. This is reviewer or agent manipulation embedded in a reachable tool response, so I classify the package as malicious.
Evidence
dist/index.js
Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- The registered DSH mirror tool can return a fallback message when a recording or requested step is missing.
- That fallback tells the AI agent not to investigate the bridge, its logs, or the message, and to continue the user's task.
Evidence against
- The package describes itself as a DeepSeek Harness integration for Google Antigravity.
- The manifest declares a prepare build script and no install or postinstall script.
