Is the Immersion Reader skill free?

Yes. The skill itself is free from rayw-lab/english-immersion-reader. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Immersion Reader SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Immersion Reader?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Immersion Reader with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 19, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · f161464

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 19, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Ran the bundled build_page.py on the demo lesson: it emitted a real 56KB interactive H5 page plus a 62KB app.js with working blind-listening, dictation, shadowing and karaoke word-sync, and validated 467/467 lexicon coverage against its JSON schema. A no-skill baseline of the same 'build an English reading lesson' request produces a flat static page with none of those study modes. Audio synthesis (edge-tts) needs live network and was not exercised; the page degrades gracefully to browser TTS, which the tool reports honestly. Authoring the segments.json with its full lexicon is still manual work the agent must do.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Immersion Reader does

Builds a self-contained H5 English deep-reading and listening lesson from an article URL, a YouTube or podcast transcript, or a prepared segments.json. Triggers when the user wants to convert English source text into an immersion study page with audio, word cards, chunk cards, dictation and shadowing. Runs a Python pipeline that validates a segment schema, injects data and word timings, and synthesizes per-word audio via edge-tts.

How to install Immersion Reader

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
