+### 🤖 Spawn1337: Autonomous Agent Protocol
+
+Spawn full-power Claude agents that run independently in their own screen sessions:
+
+```
+Parent Session → <spawn1337>task.md</spawn1337>
+  → SpawnDetector parses tag
+  → Orchestrator creates agent directory
+  → Spawns Claude in its own screen session
+  → Agent works autonomously
+  → Reports result via <promise>PHRASE</promise>
+  → Parent notified via SSE
+```
+
+**Features:**
+- **Resource governance**: Budget limits (tokens + cost), timeout enforcement, graceful shutdown
+- **Agent trees**: Agents can spawn children (max depth: 3)
+- **Communication**: Filesystem-based message bus between parent and child
+- **Max 5 concurrent** agents with queuing for overflow
+
+```yaml
+# Task spec format (YAML frontmatter in .md file)
+---
+agentId: my-agent-001
+name: My Agent
+type: implement
+priority: high
+maxTokens: 150000
+maxCost: 0.50
+timeoutMinutes: 15
