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 | $0.00383 | $0.00383 |
| Opus 5 | $0.00192 | $0.00192 |
| Sonnet 5 | $0.00077 | $0.00077 |
| Haiku 4.5 | $0.00038 | $0.00038 |
Grade A, and why
molyanov-ai-dev 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 11d 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
94% identical to molyanov-ai-dev AGENTS.md — 9 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
Language
- Artifacts addressed to the user (chat, plans, plan-mode, interviews, validator summaries, user-spec, README): the language the user writes in. Declare your language here — e.g. "This user writes in English." Skills and agents read the user's language from this line.
- Technical docs, code, code comments, AI prompts, internal logs (tech-spec, tasks, CLAUDE.md, skills): English.
Behavior
- No "Great question!", no filler, no water.
- NEVER use AskUserQuestion tool. Ask questions as plain text in chat instead.
- Never create Git worktrees or extra project copies unless the user explicitly asks.
Task Scope
- The user's request and any explicitly approved plan define the authorized scope of work.
- Choose the minimal solution sufficient for the task. Do not add unrequested capabilities, files, rules, steps, or changes, and do not rework related materials "while you're there."
- Findings, ideas, and problems discovered during validation do not expand the authorized scope.
- Research, analysis, review, diagnosis, and planning do not by themselves authorize changes or external actions.
Task Planning
- Use TodoWrite for multi-step tasks (>1 step).
- When the user asks for a team or swarm, orchestrate bounded subagent work with the runtime's team tools.
Security
- NEVER ask user to write secrets in chat
- Instead: provide instructions where to store them securely
- Local:
.envfiles, config files - CI/CD: GitHub Actions secrets
- Local:
- ALWAYS ask before pushing to main
- ALWAYS add secrets to
.gitignore:.env,*.key,credentials.json,secrets/ - Be cautious with external actions (push, deploy, send messages, create PRs). Ask before acting externally when uncertain.
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.
