frog-and-toad-studio

Frog and Toad 精读课 studio — a Claude- and Codex-compatible skill that generates per-chapter teaching materials for Arnold Lobel's Frog and Toad series (I Can Read Level 2, ESL Grade 1).

An AI-agent skill compatible with Claude and Codex for generating a complete per-chapter "三件套" (three-piece set): a projection keyword-map HTML, a one-page Student Workbook .docx, and an Answer Key .docx — plus WeChat-ready lesson summaries and Obsidian sync.

What it generates

Each story = one lesson = one 三件套:

1. 关键词地图 HTML — projection lesson plan in a locked cream-paper hand-drawn style, 5 tabs (Warm-up · Vocabulary · Story Map · Characters · Theme), with a bilingual → English-only toggle
2. Student Workbook .docx — one page, 4 fixed parts (Story Map verb fill-in · Think! inference · moral fill-in · Draw!)
3. Answer Key .docx — same page with answers in red, bold, underlined

Plus, on demand: per-lesson 课程总结与作业（微信版） paragraphs and Obsidian tracking-note sync.

First-time path setup

The repository never stores a user's home-folder path. Before running the Obsidian vocabulary sync:

1. Copy config.example.json to config.local.json.
2. Set course_root to the local Frog and Toad course-library folder.
3. Set obsidian_dir to the local Frog and Toad tracking folder inside the Obsidian vault.

Example:

{
  "course_root": "/path/to/Frog and Toad精读课",
  "obsidian_dir": "/path/to/Obsidian Vault/课程升级追踪/桥梁/Frog and Toad"
}

config.local.json is ignored by Git, so private machine paths are never included in the public repository. If the file or either directory is missing, the sync script stops with a clear setup error instead of guessing a path.

Course coverage

20 lessons across the four books, in folder/book order: Days with Frog and Toad (01–05) → Frog and Toad All Year (06–10) → Frog and Toad Together (11–15) → Frog and Toad Are Friends (16–20). See references/course-map.md for the full table.

Hard rules baked into the workflow

• Verbatim quotes only — every quote in the HTML / Workbook must match the book word-for-word
• Keywords confirmed first — the keyword list is sent to the teacher for confirmation before anything is generated
• Never invent a new layout — copy assets/template_keyword_map.html and replace content only
• Workbooks must be exactly 1 page — verified by converting to PDF and asserting page count
• HTML tag balance is self-checked with Python's HTMLParser before delivery

Notes

• Local course-library and Obsidian paths are supplied through an untracked config.local.json file. The Obsidian sync and WeChat lesson-summary steps are optional — skip them if you don't use those tools.
• Book PDFs, generated courseware, audio, and lesson-summary documents are not included in this repository — only the skill itself.
