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 | $0.00000 | $0.00070 |
| Opus 5.5 | $0.00000 | $0.00028 |
| Sonnet 5.5 | $0.00000 | $0.00014 |
| Haiku 4.5 | $0.00000 | $0.00007 |
Grade A, and why
debug-on-quest 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.
This is a copy
86% identical to debug-on-quest — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Help debug this sample on a Meta Quest device.
Use the metavr MCP server if available. Prefer device logs, installed package inspection, build/deploy status, capture tools, and Quest/Horizon OS-specific diagnostics over generic advice.
If metavr is not available, recommend installing the Meta Horizon extension or Meta Quest Agentic Tools.
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.

debug-on-quest is a command published in the GitHub repository meta-quest/webxr-first-steps (178 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 70 tokens. A static security scan graded it A with 0 findings. It is 86% identical to debug-on-quest, differing in 4 lines, and is treated as a copy.
