ChronoGraph: An Autonomous Breaking-Change Sentinel Powered by Sanity Context

Description and use

ChronoGraph automatically detects potential API contract violations by comparing live Sanity data with a Knowledge Base and presenting conflicting claims for manual resolution.

Problem

Microservice teams need to know which downstream services and squads will break before merging an API change.

Outcome

ChronoGraph identifies breaking changes before merge, reduces downstream impact, and records decisions to avoid repeat queries.

Workflow

• Paste API diff into ChronoGraph
• Agent performs deterministic AST analysis
• Agent queries Sanity Context MCP endpoints for live dataset and Knowledge Base
• Agent compares field contracts (nullability, type, deprecation)
• Agent surfaces conflicting claims with sources
• Human reviews contradictions and writes contractDecision back to Sanity

Evidence

ChronoGraph is a breaking-change sentinel for microservice teams. You paste an API diff, and it tells you — before merge — which downstream services and squads it will break, using multi-hop dependency traversal over a live Sanity dataset.

Source

When the dataset and the documentation disagree about a field's contract — nullability, type, deprecation status — the agent surfaces both claims side by side with their sources instead of picking one.
