What You Get
Skills
/skill:three-tier-framework— Load the full framework reference, tier definitions, debugging heuristic, and MCP mapping/skill:deep-module-design— Design modules for leverage, locality, testability, and clear tier ownership
Prompt Templates
/classify— Classify any system component into framework tiers/debug-tier— Apply the three-tier causality heuristic to debug a failure/mcp-design— Design an MCP server using the framework
The Framework
Every agent system has three tiers, mapped to MCP's three primitives:
| Tier | What | MCP Primitive | Control Model |
|---|---|---|---|
| Database | What exists (state, records) | Resources | Application-controlled |
| Automation | What happens (tools, skills) | Tools | Model-controlled |
| Judgment | What should happen (policy) | Prompts | User-controlled |
Debug order: Always check tiers in sequence — Database → Automation → Judgment. Lower-tier failures cascade upward.
The recursive property: MCP's sampling mechanism allows Automation to request Judgment, creating a feedback loop that mirrors embodied cognition.
Policy as artifact: Constraints flow through all tiers as data — stored in Database, transformed by Automation, evaluated by Judgment.
