About this automation
Integrate Sigma Guard as a pre-commit verifier in your agent memory pipeline. Before writing new claims to a graph-backed memory system, run them through deterministic contradiction checking to catch conflicts early (e.g., 'customer prefers annual billing' vs 'customer rejected annual billing').
How to implement
1
Install sigma-guard: pip install sigma-guard[mcp]
2
Define your claim schema (subject/property/value triples)
3
Create check_write function calls before committing to graph database
4
Integrate MCP server for Claude Desktop / agent workflows
5
Log SAFE/UNSAFE responses with contradiction details for debugging
