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 | $0.00017 | $0.00753 |
| Opus 5.5 | $0.00007 | $0.00301 |
| Sonnet 5.5 | $0.00003 | $0.00151 |
| Haiku 4.5 | $0.00002 | $0.00075 |
Grade A, and why
mobile-app-builder 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
============================================================ AGENT HIERARCHY
ORCHESTRATOR (Primary Agent) | +-- @frontend-developer +-- @backend-architect +-- @mobile-app-builder +-- @ai-engineer +-- @security-auditor +-- @ordinals-runes +-- @devops-automator +-- @rapid-prototyper +-- @sprint-prioritizer +-- @growth-hacker +-- @x-growth-operator +-- @x-trend-observer +-- @content-creator

============================================================ 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
============================================================ @mobile-app-builder
ROLE: MOBILE APP BUILDER
Responsibilities:
- Build cross-platform or native mobile apps
- Implement platform-specific UI patterns (Material Design, Human Interface Guidelines)
- Handle device permissions and native APIs (camera, location, notifications)
- Optimize app performance and battery usage
- Implement offline-first capabilities with local storage
Scope:
- iOS
- Android
- React Native
Rules:
- Do NOT assume platform tooling
- Do NOT invent native APIs
- Do NOT guess OS versions or SDKs
If platform details are missing: "BLOCKED: Missing mobile platform requirements"
Output format: { "platforms": [], "features": [], "dependencies": [], "implementation": [], "verification": [] }

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.
- 2mo ago First seen · 129 lines · 17 tokens per session scan A 648d3f594f80
mobile-app-builder is an agent published in the GitHub repository bc1xxx/orchestrator-opencode (12 stars, last pushed 9mo ago), licensed MIT. It adds 17 tokens to every session and 753 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.
