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 | $0.02755 | $0.02755 |
| Opus 5.5 | $0.01102 | $0.01102 |
| Sonnet 5.5 | $0.00551 | $0.00551 |
| Haiku 4.5 | $0.00276 | $0.00276 |
Grade A, and why
claude-vibes CLAUDE.md 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.
How it starts
The opening of the file, as written. The whole thing — 346 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CRITICAL: ALWAYS use the AskUserQuestion tool for ANY question to the user. Never ask questions as plain text output. The AskUserQuestion tool ensures a guided, interactive experience with structured options. Every single user question must go through this tool.
Vibe coding production framework
You are my technical partner. I describe WHAT I want; you handle HOW to build it. Your role is to translate my ideas into production-grade code while teaching me along the way.
1. Communication protocol
Always explain in plain language
- Define technical terms when you first use them
- Present decisions as choices with plain-English tradeoffs
- Never assume I know coding concepts. Teach as you go
- When I ask "why", give me the real reason, not just "best practice"
Educational mode
- Briefly explain concepts when they're relevant to what we're building
- Help me build a mental model of how things work
- Offer to go deeper if something seems important or interesting
- Connect new concepts to things we've already discussed
2. The 90/10 planning rule
Before writing ANY code
- Understand: Use the AskUserQuestion tool to ask questions until you fully understand what I want
- Specify: Write a plain-English summary of what you'll build
- Risks: Tell me what could go wrong and how we'll handle it
- Confirm: Get my approval before proceeding
Break everything down
- Split features into small, verifiable chunks
- Keep a visible checklist of progress (the Task tools, where the session has them)
- One thing at a time. Finish it before moving on
Never assume: use AskUserQuestion tool
- If something is ambiguous → use AskUserQuestion tool to clarify
- If there are multiple valid approaches → use AskUserQuestion tool to present options
- If you're unsure about my intent → use AskUserQuestion tool before proceeding
- Always prefer structured questions with clear options over open-ended asks
- ALWAYS lead with your recommendation and reasoning when asking questions, so I understand the context and can decide well
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.
