Choose how to use this skill
You do not need every option. Choose the path your AI client supports. The stable page stays the same; versioned files are immutable.
1. Native installer
This listing has no registered native installer command. Use the complete package or source fallback below, depending on what your client supports.
Do not guess an installer command or replace an existing version without reviewing the diff.
2. Complete package recommended
Download the ZIP when available. It includes SKILL.md plus the references, security notes and version metadata.
No complete ProSkills package is published for this listing yet.3. Prompt-only
Copy the prompt above when the agent can read the stable page or when you want to adopt the workflow without installing a skill.
Need only the instruction file?
Download SKILL.md only if your client requires a single file. The complete ZIP is safer for a full installation because it preserves the references and release context.
No path installs or executes anything by itself. Your agent still needs access to the project files. Before updating, compare the installed version and review the diff.

openclaw-language-coach
An OpenClaw skill that coaches non-native speakers by analyzing their actual messages — voice transcripts and typed text. It tracks recurring mistakes, sends weekly AI-generated lessons, and delivers daily reminders about patterns you keep getting wrong.
Built this because I wanted to actually improve my English at a professional level, not just "learn English." The difference: this watches what you actually say and catches the patterns you don't notice yourself.
What it does
- Logs your messages — every voice transcript and typed message gets appended to a JSONL file
- Tracks error patterns — when an AI or human spots a recurring mistake, it gets added to a tracked list with wrong/correct examples
- Weekly lessons — every Sunday, Claude reads your week's transcripts + tracked errors and generates a personalized lesson
- Daily nudges — picks your most frequent mistake and sends a quick reminder via Telegram
Install
Copy this repo into your OpenClaw skills directory:
cd ~/.openclaw/workspace/skills/
git clone https://github.com/nova-novanest/openclaw-language-coach.git language-coach
OpenClaw will auto-detect it from the SKILL.md frontmatter.
Setup

Set up cron jobs:
# Weekly lesson — Sundays at 7pm UTC openclaw cron add --name english-coach-weekly --schedule "0 19 * * 0" --task "Run the weekly language lesson: python3 skills/language-coach/scripts/weekly_lesson.py" # Daily nudge — every day at 7pm UTC openclaw cron add --name english-coach-daily --schedule "0 19 * * *" --task "Run the daily language nudge: python3 skills/language-coach/scripts/daily_nudge.py"
Usage
The skill integrates with your OpenClaw agent. When voice messages come in, the agent logs them automatically. You can also:
# Log a transcript manually
python3 scripts/log_transcript.py --source voice --text "transcript here"
# Add a tracked error pattern
python3 scripts/manage_errors.py add --pattern "Present tense overuse" --wrong "from that time you are not normal" --correct "since then you haven't been acting normally"
# List active errors
python3 scripts/manage_errors.py list
# Mark one as resolved
python3 scripts/manage_errors.py resolve --id present_tense_overuse
How it actually works
The weekly lesson sends your real transcripts to Claude with your tracked error list. Claude spots new mistakes, checks if old patterns are still showing up, and notes any progress. It's not a generic grammar lesson — it's built from what you actually said that week.
The daily nudge just picks your most frequent active error and sends a quick wrong/right example. Takes 2 seconds to read. That's the point.
