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 | $0.00795 | $0.00795 |
| Opus 5 | $0.00398 | $0.00398 |
| Sonnet 5 | $0.00159 | $0.00159 |
| Haiku 4.5 | $0.00080 | $0.00080 |
Grade A, and why
crypto-trading-arena 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 12d 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
crypto trading arena development guide for dummies
This file provides guidance to Claude Code, Codex, and other AI coding assistants when working on the crypto trading arena codebase.
Dependency management and development environment
Project dependencies are managed with uv.
- Do not hand-edit
pyproject.toml— useuv add <pkg>souv.lockstays canonical. - Use
uv runto execute project files and tests.
Architecture
crypto trading arena uses event-driven agents that consume data streams through Kafka. Each agent is safe to deploy on its own host, and can consume data-streams to make decisions on realtime data.
Conventions
- Commits/PRs landing on
mainuse conventional-commit prefixes:feat:,fix:,chore:,docs:,refactor:,test:,perf:,style:. Pick the narrowest accurate one. PR titles follow the same style. - Ruff clean for new/changed files.
- Comments and docstrings explain why, not what.
Sub-agents
- When planned work is large, you may spawn sub-agents to split up or parallelize the work where possible
- Always spawn sub-agents with the opus model and xhigh thinking effort
- Spawn intelligent sub-agents generously for any kind of review work, investigation, and intel gathering. The goal is a wide and deep fan-out.
Test driven development
- When implementing any code, please follow test driven development principles using the skill
/test-driven-development - Use the skill
/pytest-coverageto check your test completeness.
Deep implementation reviews
- Use
/pr-review-toolkit:review-prto deeply review the code changes for:- functional bugs and issues,
- anti-patterns,
- test coverage,
- documentation correctness & coverage
- Review implementations using the
/simplifyskill to surface any potential design or implementation simplifications using more elegant, well-engineered solutions or designs. - In certain cases, when prompted, you may have to go through multiple rounds of deep reviews for code changes. In these events, the review is not considered done until the findings from consecutive review rounds converge towards no critical or must-fix issues.
- Spawn intelligent sub-agents generously for any kind of review work, investigation, and intel gathering. The goal is a wide and deep fan-out.
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.
