# tengu_v3_intel_insider_form144

INSIDER INTENT-TO-SELL NOTICES — supply before it hits the tape. Form 144 is filed BEFORE a sale of restricted or control stock, so it is forward-looking: who intends to sell, roughly how many shares, through which broker, at what notified market value, and how the stock was acquired. Call it to see overhang building ahead of the completed sales, which only show up later in the Form-4 flow. A notice is an INTENT — it may be executed smaller, later, or not at all, so never treat notified value as realised selling.

## Why tengu_v3_intel_insider_form144 is rated Low

Even though tengu_v3_intel_insider_form144 only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call tengu_v3_intel_insider_form144 to retrieve information from Tengu without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Tengu:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "tengu_v3_intel_insider_form144": {}
  }
}
```
