+# MMA Hierarchical Delegation: Recommended Architecture
+
+## 1. Overview
+The Multi-Model Architecture (MMA) utilizes a 4-Tier hierarchy to ensure token efficiency and structural integrity. The primary agent (Conductor) acts as the Tier 2 Tech Lead, delegating specific, stateless tasks to Tier 3 (Workers) and Tier 4 (Utility) agents.
+
+## 2. Agent Roles & Responsibilities
+
+### Tier 2: The Conductor (Tech Lead)
+- **Role:** Orchestrator of the project lifecycle via the Conductor framework.
+- **Context:** High-reasoning, long-term memory of project goals and specifications.
+- **Key Tool:** `mma-orchestrator` skill (Strategy).
+- **Delegation Logic:** Identifies tasks that would bloat the primary context (large code blocks, massive error traces) and spawns sub-agents.
+
+### Tier 3: The Worker (Contributor)
+- **Role:** Stateless code generator.
+- **Context:** Isolated. Sees only the target file and the specific ticket.
+- **Protocol:** Receives a "Worker" system prompt. Outputs clean code or diffs.
+- **Invocation:** `.\scripts
+un_subagent.ps1 -Role Worker -Prompt "..."`
+
+### Tier 4: The Utility (QA/Compressor)
+- **Role:** Stateless translator and summarizer.
+- **Context:** Minimal. Sees only the error trace or snippet.
+- **Protocol:** Receives a "QA" system prompt. Outputs compressed findings (max 50 tokens).
+- **Invocation:** `.\scripts
+un_subagent.ps1 -Role QA -Prompt "..."`
+
+## 3. Invocation Protocol
+
+### Step 1: Detection
+Tier 2 detects a delegation trigger:
+- Coding task > 50 lines.
+- Error trace > 100 lines.
+
+### Step 2: Spawning
+Tier 2 calls the delegation script:
+```powershell
+.\scripts
+un_subagent.ps1 -Role <Worker|QA> -Prompt "Specific instructions..."
+```
+
+### Step 3: Integration
+Tier 2 receives the sub-agent's response.
+- **If Worker:** Tier 2 applies the code changes (using `replace` or `write_file`) and verifies.
+- **If QA:** Tier 2 uses the compressed error to inform the next fix attempt or passes it to a Worker.
