## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_session_brief",
    "arguments": {}
  }
}
```

## Why get_session_brief is rated Low

The tool retrieves historical session information to restore context in conversations. No modification, deletion, or code execution occurs. The empty description reduces confidence slightly, but the 'get_' prefix and sibling tools (mostly retrieval-focused like 'cross_repo_search', 'dependency_graph', 'explain_change') strongly suggest read-only retrieval of session summaries.

From the tool's own definition: "Tool name 'get_session_brief' with no descriptive text; based on context of a memory/history server and sibling tools like 'context_pack' and 'episodic_search', this retrieves prior session summaries. Verb 'get' indicates data retrieval."

## Use case

AI agents call get_session_brief to retrieve information from CogniRepo 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 CogniRepo:

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