Every single sub-command breaks with a plain 'cp -r skills/language-coach ~/.claude/skills/' install because SKILL.md hardcodes '../../scripts/manage_language_coach.py', which lives two directories above the skill folder alongside a shared/ and platforms/ package; confirmed by actually running the copied skill and getting 'No such file or directory' on every command until the whole repo was kept intact.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 3/5
- Triggers reliably 5/5
- Output vs. baseline 8/10
- Docs & honesty 4/5
What Language Coach does
A slash-command handler (/language-coach setup|native|target|style|response|goal|mode|status|off|on|...) that stores a persistent language-learning profile and, once its UserPromptSubmit hook is installed, injects grammar/style coaching before every answer. Triggers only on explicit /language-coach invocations, not on generic 'help me practice French' requests; a sibling skill (language-review) handles progress analytics.
How to install Language Coach
git clone https://github.com/leeguooooo/prompt-language-coach
mkdir -p ~/.claude/skills
cp -r prompt-language-coach/skills/language-coach ~/.claude/skills/language-coach
# MANUAL STEP REQUIRED: also copy prompt-language-coach/scripts/, shared/, and platforms/ preserving the repo's relative layout (or symlink the skill dir out of a full repo clone) -- every sub-command shells out to ../../scripts/manage_language_coach.py, which only resolves if the skill folder stays two levels under the original repo root.
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.

Frequently asked questions
- Is the Language Coach skill free?
- Yes. The skill itself is free from leeguooooo/prompt-language-coach. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Language Coach work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 16, 2026. Verdict: Works with setup. Every single sub-command breaks with a plain 'cp -r skills/language-coach ~/.claude/skills/' install because SKILL.md hardcodes '../../scripts/manage_language_coach.py', which lives two directories above the skill folder alongside a shared/ and platforms/ package; confirmed by actually running the copied skill and getting 'No such file or directory' on every command until the whole repo was kept intact.
- What is the Language Coach SkillProof Score?
- 8.0/10 — installs cleanly 3/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 4/5.
- How do I install Language 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 Language 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.
