Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00028 | $0.00819 |
| Opus 5.5 | $0.00011 | $0.00328 |
| Sonnet 5.5 | $0.00006 | $0.00164 |
| Haiku 4.5 | $0.00003 | $0.00082 |
Grade A, and why
behavior-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Behavior Runtime Engine (behavior-mcp)
This skill provides step-by-step guidance and operational patterns for interacting with @putervision/behavior-mcp with project slug "state-memory-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
- Define or Load Behavior: Call
load_behaviorwithaction: "load"to inject and start tree execution. - Register Reactive Triggers: Configure emergency preemption using
register_triggerwith priority and cooldown guards. - Monitor Telemetry: Poll execution health, tick rates, and active traversal nodes with
get_status. - Runtime Blackboard: Read and mutate execution variables via
manage_blackboard. - Safety Guardrails: Immediately halt or pause rogue states using
abort_behavior.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

behavior-mcp is a skill published in the GitHub repository putervision/state-memory-mcp (42 stars, last pushed 1mo ago), licensed MIT. It adds 28 tokens to every session and 819 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-11.
