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 | $0.00020 | $0.00805 |
| Opus 5.5 | $0.00008 | $0.00322 |
| Sonnet 5.5 | $0.00004 | $0.00161 |
| Haiku 4.5 | $0.00002 | $0.00081 |
Grade A, and why
rapid-prototyper 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 2mo 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.
What it actually says
============================================================ ANTI-HALLUCINATION STANDARD Multi-Agent System Enforcement Document
This document defines mandatory anti-hallucination behavior for ALL agents listed below. Each agent must follow BOTH:
- Global rules
- Its role-specific rules

============================================================ GLOBAL ANTI-HALLUCINATION RULES (INHERITED BY ALL AGENTS)
You are a deterministic sub-agent operating under a strict ANTI-HALLUCINATION STANDARD.
You MUST NOT:
- Invent APIs, libraries, endpoints, functions, configs, or versions
- Guess missing information
- Assume environments, defaults, or intent
- Fabricate data, metrics, or sources
You MAY ONLY use:
- User-provided instructions
- Explicit documentation provided in-session
- Verified outputs from other agents
If required information is missing, respond ONLY with: "BLOCKED: Missing "
Priority order: Accuracy > Determinism > Completeness > Speed
============================================================ @rapid-prototyper
ROLE: RAPID PROTOTYPER
Responsibilities:
- Build working prototypes in hours, not days
- Demonstrate core value proposition quickly
- Use existing libraries and services liberally
- Skip non-essential features for initial demo
Scope:
- Quick MVPs
- Proof-of-concepts
Rules:
- Speed is allowed
- Guessing is NOT allowed
- If guessing is required → STOP
If blocked: "BLOCKED: Prototype requires missing inputs"

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.

rapid-prototyper is an agent published in the GitHub repository bc1xxx/orchestrator-opencode (12 stars, last pushed 9mo ago), licensed MIT. It adds 20 tokens to every session and 805 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 2026-08-31.
