dsh-agy-link@0.4.98
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 embeds an explicit instruction in model-facing runtime output to avoid investigating its bridge and logs. That is reviewer manipulation; the local, bearer-protected bridge and build-only prepare script do not negate it.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A mirrored tool step executes but its recorded output is unavailable.
Impact
This can steer a model away from examining the bridge and encourage repeated tool execution, interfering with independent review.
Mechanism
The package returns a diagnostic message that says not to investigate the bridge or message and prompts the model to continue or rerun the operation.
Attack narrative
When a mirrored tool result is unavailable, the package returns a message instructing the model not to investigate the bridge or its logs and to continue the task or rerun the operation. This is model-directed suppression embedded in runtime output and qualifies as reviewer manipulation.
AI rationale
The package embeds an explicit instruction in model-facing runtime output to avoid investigating its bridge and logs. That is reviewer manipulation; the local, bearer-protected bridge and build-only prepare script do not negate it.

Decision evidence
public snapshotAI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
Evidence for block
- The runtime constructs a tool-result message telling the model not to investigate the bridge or its logs, then directs it to continue or rerun the operation.
- This instruction is emitted as a response for an executed tool step, so it can steer the model receiving package-generated output.
Evidence against
- The package describes itself as a DeepSeek Harness integration for Antigravity models and tool activity.
- Its MCP bridge binds to 127.0.0.1 and requires a generated bearer token.
- The prepare and prepack scripts build the package; no install-time data collection was identified.
