fluent-learn

An adaptive language-learning session that combines reading, writing, speaking, and vocabulary exercises according to the learner's level, weaknesses, and scheduled reviews.

In plain words
What is it for?
It is for running a 15–20 minute mixed practice session with immediate feedback and review tracking, started with `/fluent-learn` after setup.
Why use it?
It creates a daily practice plan based on existing learner data instead of giving every learner the same exercises.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fluent-learn scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Main Adaptive Learning Session

Overview

The flagship command. Interleaves skills, adapts difficulty per answer, and covers the whole evidence-based loop: active recall → immediate feedback → spaced repetition → tracking. Typically runs 15-20 min, mixing 2-3 patterns to force discrimination.

When to Use

Trigger this skill only when the learner types /fluent-learn. The skill is gated with disable-model-invocation: true — an ambiguous auto-trigger would launch a 20-min interactive session and mutate 6 JSON databases.

Skip this skill the very first time a learner runs the system — route to /fluent-setup instead.

Instructions

1. Load learner context

python3 "${CLAUDE_PLUGIN_ROOT:-${CLAUDE_PROJECT_DIR:-.}}/.claude/hooks/read-db.py"

Need all 6 DBs. If any missing, direct the learner to /fluent-setup and stop.

2. Analyze today's plan

  • Streak: learner-profile.current_streak_days
  • Due reviews: computed.due_reviews_count
  • Weak patterns: mistakes-db.error_patterns where mastery_level <= 2 (descending by frequency)
  • Recent performance: progress-db.weekly_summary
  • Skills not practiced recently: check mastery-db.skills_mastery.{skill}.last_practiced

3. Greet

# {greeting in target language}, {name}! 👋

**Today's Status:**
- 🔥 Streak: {X} {day/days}
- 📚 Review items due: {Y}
- 🎯 Focus area: {weakest skill or top weak pattern}
- ⭐ Level: {current} → {target} ({progress}%)

**What would you like to practice today?**

1. 📝 Writing (emails, letters, forms)
2. 🗣️ Speaking (typed conversation)
3. 📖 Vocabulary (flashcard drills)
4. 👀 Reading (comprehension)
5. 🔄 Spaced Review (today's due items)
6. 🎲 Surprise me! (adaptive mix)

**Type a number or skill name:**

4. Route

  • 1-5 → hand off to the matching skill (fluent-writing, fluent-speaking, fluent-vocab, fluent-reading, fluent-review). Those skills cover everything needed; this skill's job here is just to dispatch.
  • 6 (adaptive mix) → use this skill's own exercise sequencer (below).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fluent-learn is a skill published in the GitHub repository m98/fluent (381 stars, last pushed 2mo ago), licensed MIT. It adds 85 tokens to every session and 1,861 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
