trust_diff
ActiveTool of SaSame Research Agent
Show exactly what CHANGED for one public MCP server between its two most recent SaSame observations: which standard criteria (C1..C10) newly FAIL or newly PASS, the grade change, and how many days apart. Answers 'WHY did this server's grade move?' — e.g. 'newly fails C7 (stopped returning real content)'. Proprietary change-detection an agent cannot self-produce; pair with trust_trajectory for full history. Read-only, cost-zero, observed level (third-party measurement, not endorsement).
