What is Opencode-Howto CLAUDE.md?

A set of project instructions for OpenCode, an AI coding assistant, working on a Chinese training tutorial. It documents the project structure, development setup, EPUB ebook building, tests, code checks, and localization checks.

Use it when developing the tutorial, running Python tests, checking code quality or localization, and creating the EPUB output.

It gives the coding assistant and developers one place to find the repository’s working rules and commands. This reduces uncertainty about how to build and verify changes.

Token cost

What it costs to keep this loaded

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	$0.01747	$0.01747
Opus 5.5	$0.00699	$0.00699
Sonnet 5.5	$0.00349	$0.00349
Haiku 4.5	$0.00175	$0.00175

Security

Grade A, and why

Opencode-Howto 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 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.

Project Overview

OpenCode Howto — 基于 Claude Code Howto 中文版（上游在 claude-howto-zh-cn-main/）适配的 OpenCode 内部培训教程。核心机制是通过 OpenCode 对话窗口中的 skills（自测 + 模块测验）引导用户从自我评估到分阶段学习 10 个功能模块。

详细项目需求见 PROJECT_OVERVIEW.md。

Build / Test / Lint Commands

Python 脚本在 scripts/ 目录，需要 uv 包管理器。

# 开发环境
uv venv && uv pip install -r scripts/requirements-dev.txt

# EPUB 构建
uv run scripts/build_epub.py --root . --output output.epub --verbose

# 测试
uv run pytest scripts/tests/ -v                                    # 全部
uv run pytest scripts/tests/test_validate_localization.py -v       # 单文件
uv run pytest scripts/tests/test_validate_localization.py::test_validate_markdown_links_detects_missing_file -v  # 单函数

# Lint & 格式化
uv run ruff format scripts/          # 格式化
uv run ruff check --fix scripts/     # lint 修复
uv run bandit -c scripts/pyproject.toml -r scripts/ --exclude scripts/tests/  # 安全扫描

# 本地化验证
uv run python scripts/validate_localization.py

# Pre-commit
