# Behavior Runtime Engine (behavior-mcp)

This skill provides step-by-step guidance and operational patterns for interacting with `@putervision/behavior-mcp` with project slug `"world-model-mcp"`.

---

## 1. Role in the PuterVision Pentad
- **Workflow State** (`state-memory-mcp`): Persistent task DAGs, decisions, milestones, and blockers.
- **Perception** (`vision-memory-mcp`): Visual layout caching, screenshots, and visual specifications.
- **Spatial World** (`world-model-mcp`): Persistent 3D/2D coordinates, bounding boxes, and topological relations.
- **Strategic Reasoning** (`agent-reasoning-mcp`): Strategic BDI goals, utility scoring, and intention dispatch.
- **Tactical Execution** (`behavior-mcp`): High-frequency (~60Hz) deterministic behavior tree execution directly in browser runtimes with reactive interrupts.

---

## 2. Core Operational Sequence
1. **Define or Load Behavior**: Call `load_behavior` with `action: "load"` to inject and start tree execution.
2. **Register Reactive Triggers**: Configure emergency preemption using `register_trigger` with priority and cooldown guards.
3. **Monitor Telemetry**: Poll execution health, tick rates, and active traversal nodes with `get_status`.
4. **Runtime Blackboard**: Read and mutate execution variables via `manage_blackboard`.
5. **Safety Guardrails**: Immediately halt or pause rogue states using `abort_behavior`.

| `abort_behavior` | `abort`, `pause`, `resume` | `execution_id`, `reason` | Immediately halt, pause, or resume execution and disengage active inputs. |
| `register_trigger` | `register`, `list` | `name`, `condition_type`, `priority`, `cooldown_ms`, `behavior_name` | Configure reactive interrupt triggers with priority preemption and cooldowns. |
| `replay_recording` | `capture`, `list` | `recording_id`, `execution_id`, `frames`, `name` | Capture or replay deterministic browser action sequences with adaptive timing. |
| `get_metrics` | `current`, `history`, `aggregate`, `compare` | `execution_id`, `behavior_name`, `limit` | Retrieve execution telemetry, tick durations, stuck events, and statistics. |
| `manage_behaviors` | `register`, `list`, `get` | `name`, `version`, `tree`, `tree_json`, `description` | CRUD operations for immutable JSON behavior trees with SHA-256 tree hash verification. |
