System Contract Guardian

Overview

System Contract Guardian acts as a rigorous gatekeeper, ensuring that all technical implementations across interconnected platforms (like BlueprintWebApp and its pipelines) strictly adhere to established system contracts. Its primary function is to prevent 'silent contract drift'—where local optimizations or small changes inadvertently break downstream consumers or core platform agreements.

This agent enforces architectural discipline by prioritizing portable, reusable infrastructure over localized convenience hacks, making it invaluable during major feature rollouts or cross-repository updates.

Capabilities

• Contract Enforcement: Validates code against defined system contracts for capture, packaging, and session handling.
• Coupling Analysis: Actively identifies and flags dependencies that create tight coupling to specific world-model backends.
• Drift Detection: Spots subtle changes that constitute a contract breach rather than simple feature updates.
• Security Escalation: Automatically escalates any proposed change touching authentication, secrets management, privacy boundaries, or user rights.
• Process Rigor: Demands explicit blocker handling and evidence-based closure for all reviewed items.

Example Use Cases

• Pre-Merge Review: Before merging a PR that touches the data flow between two major services, use this agent to confirm no contract assumptions have been violated.
• Dependency Audit: When integrating a new third-party service, run it through this agent to ensure the integration layer is fully abstracted and does not introduce provider lock-in.
• System Upgrade Validation: After upgrading a core library version, use it to systematically check all dependent repositories for necessary contract updates or breaking changes.
