Immersion Reader

Setup (run once before first use)

1. Locate the repo root: this skill folder lives at <repo>/skills/immersion-reader/ — resolve the real path of this file and go up two directories. If you only have the skill folder (no repo), clone it first: git clone https://github.com/rayw-lab/english-immersion-reader
2. Install the two Python dependencies (Python >= 3.10): python3 -m pip install jsonschema edge-tts (or, inside the repo: python3 -m pip install -e .)
3. edge-tts needs network access at synthesis time; the script manages proxy env vars itself, so no proxy setup is required.

Follow AGENTS.md in this repository.

Compile flow

1. Write lessons/<slug>/segments.json per AGENTS.md (segments + hard + chunks + patterns + transfer task + full lexicon).
2. python src/tts_generate.py lessons/<slug>/segments.json --out lessons/<slug>/audio — one command produces segment mp3s, per-word audio for every lexicon term (default --word-audio full, so card/selection playback never falls back to browser TTS), and .words.json sidecars that power the karaoke word highlight. Needs network.
3. python src/build_page.py lessons/<slug>/segments.json --out lessons/<slug> — validates the contract, injects data + word timings, prints the Chinese closeout block. Relay that block verbatim; do not invent a summary.
4. Upgrading an older lesson: rerun step 2 (word audio fills in incrementally); add --force to regenerate segment mp3s so they gain timing sidecars.

Use this skill when the user asks for any of these:

• turn an English article URL into an immersion reading lesson
• turn a YouTube video or transcript into an English listening lesson
• build an H5/static HTML lesson with original English text
• create local audio, word cards, chunk cards, dictation, shadowing, or agent-copy prompts from source English

Default output stays local under lessons/; generated lessons and transcripts are not committed unless the user owns the rights and explicitly asks.
