How do I install English Coach?

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 English Coach 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: 9.2/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · cdc05c5

Ran a real message with 4 planted errors ('I go to store yesterday to buying...familly...whats the weather...tokyo') through it: skill output caught all 4 with strikethrough/bold diffs, category tags, and a grammar tip, versus the baseline's plain weather answer that ignored the errors entirely — but the 'adapts to the user's level over time' claim has no memory/persistence mechanism, it only works within one conversation's context.

What English Coach does

Wraps every reply in a two-part structure: answer the user's actual question first, then a separated 'English Corrections' block that flags up to 5 grammar/spelling/word-choice/punctuation mistakes with before/after diffs and category tags, plus a rotating phrase-of-the-day or grammar tip. Triggers when a user wants to practice English through real conversation; explicitly excludes code reviews and technical docs.
