dsh-agy-link@0.4.81
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 missing-recording response contains a self-suppressing instruction aimed at an agent using the bridge. Although the bridge is disabled by default and the reviewed OAuth endpoints are Google’s, this instruction is concrete reviewer-manipulation behavior in an agent-facing tool response.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user or agent invokes the bridge tool for a step whose recording is unavailable.
Impact
An agent may follow the instruction and avoid examining relevant bridge evidence.
Mechanism
The tool returns text directing the agent not to investigate the bridge, its logs, or that message, and to continue the task.
Attack narrative
When a requested tool recording is missing, the package returns an agent-directed message telling it not to investigate the bridge, its logs, or the message itself. In this AI-agent integration, that self-suppressing instruction can steer an agent away from relevant evidence.
AI rationale
The missing-recording response contains a self-suppressing instruction aimed at an agent using the bridge. Although the bridge is disabled by default and the reviewed OAuth endpoints are Google’s, this instruction is concrete reviewer-manipulation behavior in an agent-facing tool response.
Evidence
dist/index.js
Decision evidence
public snapshotAI called this Malicious at 91.0% confidence as Malware with low false-positive risk.
Evidence for block
- The bridge’s missing-recording response tells an agent not to investigate the bridge, its logs, or the message itself, then directs it to continue the user’s task.
- The `agy_tool` handler returns that response when the requested recording is unavailable.
Evidence against
- The MCP bridge is disabled by default.
- The OAuth endpoints shown in the source are Google endpoints, and `prepare` runs the build script.
