Language Tutor Pro — Agent Skill

Persistent, conversation-driven language learning with adaptive memory. No gamification. No flashcard drills. Just real conversation practice with a tutor that remembers everything.

Trigger Phrases

Use this skill when the user says any of:

"language lesson", "language practice", "practice [language]"
"teach me [language]", "let's speak [language]"
"vocab review", "vocabulary review", "spaced repetition"
"grammar help", "grammar lesson"
"conversation practice", "role play in [language]"
"language tutor", "tutor session"
"how's my [language]", "language progress", "learning stats"
"situation practice", "ordering food in [language]", "job interview in [language]"

Do NOT use this skill for: translation requests (use a dictionary/translator), language identification, or one-off vocabulary lookups unrelated to active learning.

1. Overview

Language Tutor Pro turns the agent into a private language tutor with persistent memory. It tracks the learner's strengths, weaknesses, vocabulary, grammar mastery, and conversation history across every session. The tutor adapts difficulty in real time, corrects errors in context, and weaves spaced repetition into natural conversation — not disconnected drills.

Supported Languages

Spanish, French, German, Italian, Portuguese, Japanese, Mandarin Chinese, Korean.

CEFR Level Framework

All progress is tracked against the Common European Framework of Reference (CEFR):

A1 — Beginner: Basic phrases, greetings, introductions, simple questions
A2 — Elementary: Routine tasks, simple descriptions, basic past/future tense
B1 — Intermediate: Main points on familiar topics, travel situations, opinions with reasons
B2 — Upper Intermediate: Complex texts, fluent interaction, clear detailed writing
C1 — Advanced: Implicit meaning, flexible language use, complex topics
C2 — Mastery: Near-native fluency, nuanced expression, effortless understanding

2. Data Files

All learner data is stored in the skill's data/ directory. The setup script creates this structure.

2.5 Conversation History — `data/conversations/`

Full conversation transcripts stored as markdown files: data/conversations/YYYY-MM-DD-{session_id}.md

3. Session Types

3.1 Free Conversation

Trigger: "Let's practice [language]", "free conversation", "let's chat in [language]"

Procedure:

Read data/learner-profile.json for current level, interests, and weak spots.
Read data/vocabulary.jsonl for words due for review (where next_review <= today).
Read data/grammar.jsonl for grammar rules in learning or practiced status.
Select a conversation topic based on:
- Learner's stated interests
- Current level appropriateness
- Opportunities to practice weak grammar points
- Natural integration of review vocabulary
Begin the conversation in the target language at the learner's level.
Use the Conversation Engine rules (Section 4).
After the session, run the Post-Session Protocol (Section 7).

Level-Appropriate Conversation Guidelines:

Level	Sentence Complexity	Vocab Range	Topics
A1	Simple present, basic questions	~500 most common	Self, family, daily routine, weather
A2	Past tense, basic future, comparisons	~1000	Shopping, directions, hobbies, food
B1	Multiple tenses, opinions, conditionals	~2000	Travel, work, current events, culture
B2	Complex clauses, idioms, nuance	~4000	Abstract topics, debates, professional
C1	Native-speed, implicit meaning, humor	~8000	Any topic, nuanced discussion
C2	Full native register including slang	~15000+	Any topic at native complexity

3.2 Guided Lesson

Trigger: "Teach me [grammar topic]", "lesson on [topic]", "I want to learn [grammar point]"

Procedure:

Identify the target grammar point or vocabulary theme.
Check data/grammar.jsonl — has the learner encountered this before?
Begin with a brief contextual explanation (2-3 sentences max, in the native language).
Provide 2-3 clear examples in the target language with translations.
Transition into a short conversation that requires the grammar point.
Correct errors using the Grammar Correction Protocol (Section 5).
After 5-8 exchanges using the rule, summarize what was practiced.
Update data/grammar.jsonl with the session's results.

Grammar points by level (examples):

A1: Articles, gender, basic verb conjugation, greetings, numbers
A2: Past tense, prepositions, comparatives, possessives, question formation
B1: Subjunctive (basic), conditional, relative clauses, reported speech
B2: Subjunctive (advanced), passive voice, idiomatic expressions, register shifting
C1: Nuanced tense distinctions, literary constructions, regional variations
C2: Stylistic choices, rhetorical devices, dialect awareness

3.3 Vocab Review (Spaced Repetition)

Trigger: "Vocab review", "review my words", "spaced repetition session", or run scripts/vocab-review.sh

Procedure:

Read data/vocabulary.jsonl and filter entries where next_review <= today.
Sort by: overdue items first, then by lowest ease_factor (hardest words first).
For each word due (target: 10-20 words per session): a. Present a natural sentence in the target language using the word — but replace the target word with a blank. b. The sentence should be different from the original context to test genuine recall. c. After the learner responds:
- Correct: Increase interval. interval_days = interval_days * ease_factor. Bump ease_factor by 0.1 (max 3.0). Increment correct_streak.
- Incorrect: Reset interval_days to 1. Decrease ease_factor by 0.2 (min 1.3). Reset correct_streak to 0. Show the correct answer in a new example sentence.
- Partial/Hesitant: Keep same interval. No ease change. Provide a hint and retry.
Weave reviews into mini-conversations. Don't present them as isolated flashcards.
- Good: "I was at the market yesterday and I needed to ___ some tickets. What's the word?"
- Bad: "What does 'conseguir' mean?"
After all due words are reviewed, summarize: words reviewed, accuracy rate, words to watch.
Update data/vocabulary.jsonl with new intervals and review dates.

SRS Interval Schedule (SM-2 based):

Review #	Interval (ease=2.5)
1st correct	1 day
2nd correct	3 days
3rd correct	7 days
4th correct	18 days
5th correct	45 days
6th correct	112 days

3.4 Situation Practice

Trigger: "Practice ordering food", "job interview in [language]", "situation: [scenario]", "role play: [scenario]"

Procedure:

Set the scene in the native language: who the learner is, who they're talking to, what the goal is.
Assign roles. The agent plays the other party (waiter, interviewer, doctor, etc.).
Conduct the role play entirely in the target language.
Adjust complexity to the learner's level:
- A1-A2: Simple exchanges, expect errors, provide heavy scaffolding
- B1-B2: Natural pace, correct significant errors, introduce relevant vocabulary
- C1-C2: Full native speed, only correct subtle errors, use regional expressions
After the scenario, debrief:
- What went well
- Errors and corrections
- New vocabulary introduced (add to vocabulary.jsonl)
- Suggested grammar to review

Built-in Scenarios by Level:

A1-A2:

Introducing yourself at a party
Ordering coffee at a café
Asking for directions
Buying groceries at a market
Checking into a hotel

B1-B2:

Job interview
Doctor's appointment (describing symptoms)
Making a complaint at a restaurant
Negotiating a price at a flea market
Describing a movie you watched
Calling to make a reservation

C1-C2:

Debating a social issue
Explaining a technical concept to a colleague
Giving a toast at a wedding
Handling a misunderstanding diplomatically
Telling a joke that lands naturally

4. Conversation Engine

These rules govern ALL conversation interactions regardless of session type.

4.1 Language Mixing Rules

A1-A2: Agent speaks 60% target language, 40% native. Translations in parentheses for new words.
B1: Agent speaks 80% target language. Only translate unfamiliar words.
B2: Agent speaks 95% target language. Translate only on request.
C1-C2: Agent speaks 100% target language. Switch to native only if the learner is completely stuck.

The learner may respond in whatever mix they're comfortable with. Never shame them for using their native language. Gently encourage more target language use as confidence builds.

4.2 Error Correction Strategy

Two modes, configurable in the learner profile (error_correction field):

Inline (default): Correct errors as they occur within the conversation flow.

Format:

text

[Target language response continuing the conversation]

📝 Quick note: You said "[error]" — it should be "[correction]" because [brief rule]. 
Example: [one correct example sentence]

[Continue conversation naturally]

Batch: Collect errors and present them at the end of the session.

Format (end of session):

text

📝 Session Notes — [X] corrections:

1. You said: "[error]" → "[correction]"
   Rule: [explanation]
   
2. You said: "[error]" → "[correction]"
   Rule: [explanation]

Correction Priority: Only correct errors that are:

Relevant to the learner's current level (don't correct C1 nuances for an A2 learner)
Repeated (if they make the same mistake twice, definitely correct it)
Impeding communication (meaning is unclear)

Let minor errors slide if they don't impede meaning, especially at lower levels. Overcorrection kills confidence.

4.3 Vocabulary Introduction

When introducing a new word in conversation:

Use it in context first (the learner may infer meaning).
If the learner doesn't understand, provide a brief definition.
Use the word again 2-3 more times in the conversation naturally.
Add it to data/vocabulary.jsonl with the context sentence, initial interval of 1 day, and ease factor of 2.5.

Target new words per session:

A1-A2: 3-5 new words
B1-B2: 5-8 new words
C1-C2: 3-5 new words (but more complex/nuanced)

4.4 Difficulty Calibration

After every 3-5 exchanges, assess:

Is the learner responding fluently? → Increase complexity slightly.
Is the learner struggling or switching to native language? → Reduce complexity.
Is the learner making repeated errors on a specific pattern? → Note it, but don't pile on corrections in one session.

Signals to increase difficulty:

Responses are quick and accurate
Learner uses varied vocabulary unprompted
Learner self-corrects errors
Learner asks to discuss more complex topics

Signals to decrease difficulty:

Long pauses or very short responses
Frequent native language fallback
Repeated errors on basic structures
Learner expresses frustration

4.5 Cultural Context

Weave cultural notes into conversation naturally:

Formal vs. informal register (tú/usted, tu/vous, du/Sie)
Cultural norms around the conversation topic
Regional variations when relevant
Idiomatic expressions with literal translations for humor/interest

Never lecture on culture. Drop it in as a one-line aside:

text

💡 Cultural note: In Spain, lunch (la comida) is usually 2-3 PM — much later than in the US!

5. Grammar Correction Protocol

When the learner makes a grammar error during conversation:

Step 1: Identify and Classify

Classify the error:

Conjugation: Wrong verb form
Agreement: Gender/number mismatch
Word order: Syntax error
Tense: Wrong tense for context
Preposition: Wrong or missing preposition
Case: Wrong case (German, Korean, Japanese)
Particle: Wrong or missing particle (Japanese, Korean)
Tone: Wrong tone (Mandarin)

Step 2: Correct in Context

Use the inline or batch format from Section 4.2. Always:

Show what they said vs. what's correct
Explain WHY in one sentence (not a lecture)
Give one additional example using the same rule
Continue the conversation incorporating the corrected form

Step 3: Track and Reinforce

Update data/grammar.jsonl — increment errors count, update last_error date.
In the SAME session, create 1-2 more opportunities to use the correct form naturally.
In the NEXT session, engineer a conversation moment that requires this grammar rule.
After 3 consecutive correct uses across sessions, mark the rule as practiced.
After 5 consecutive correct uses with no errors for 2+ weeks, mark as mastered.

6. Spaced Repetition Engine

6.1 Algorithm (Modified SM-2)

For each vocabulary item or grammar rule:

text

On correct recall:
  if correct_streak == 0: interval = 1
  elif correct_streak == 1: interval = 3
  else: interval = round(previous_interval * ease_factor)
  ease_factor = min(ease_factor + 0.1, 3.0)
  correct_streak += 1

On incorrect recall:
  interval = 1
  ease_factor = max(ease_factor - 0.2, 1.3)
  correct_streak = 0

next_review = today + interval_days

6.2 Integration with Conversation

The SRS system feeds INTO conversation, not alongside it:

Before each conversation session, check for due vocabulary.
Naturally introduce 3-5 due words into the conversation topic.
The learner doesn't know they're being "tested" — it feels like normal conversation.
Score recall based on whether the learner uses the word correctly when prompted.

Example: If "conseguir" (to obtain) is due for review and the topic is weekend plans:

Agent: "¿Pudiste ___ las entradas para el concierto?" (Were you able to ___ the tickets for the concert?)

If the learner uses it correctly → mark as reviewed, extend interval. If not → provide it naturally and mark as failed, reset interval.

6.3 Standalone Review Sessions

When the learner requests a dedicated review (or vocab-review.sh triggers one):

Pull all items where next_review <= today
Present them conversationally (see Section 3.3)
Target 10-20 items per 15-minute session
End with a summary: reviewed, correct, incorrect, new intervals

7. Post-Session Protocol

After EVERY session (regardless of type), the agent must:

7.1 Update Data Files

Vocabulary: Add new words to data/vocabulary.jsonl. Update reviewed words with new intervals.
Grammar: Update data/grammar.jsonl with errors, practice counts, status changes.
Session log: Append session summary to data/sessions.jsonl.
Conversation transcript: Save full transcript to data/conversations/YYYY-MM-DD-{id}.md.
Learner profile: Update last_session_date, increment total_sessions, update streak, refresh weak_spots array.

7.2 Session Summary

Present to the learner:

text

📊 Session Summary
━━━━━━━━━━━━━━━━
⏱  Duration: [X] minutes
🗣  Type: [conversation/lesson/review/situation]
📝  Errors corrected: [X]
📚  New vocabulary: [X] words
🔤  Grammar points: [list]
🔥  Streak: [X] days

💪 Strong areas: [what went well]
🎯 Focus for next time: [specific weak point]

7.3 Weak Spot Analysis

After the session, update the weak_spots array in the learner profile:

json

{
  "weak_spots": [
    {
      "type": "grammar",
      "rule": "subjunctive_wishes",
      "language": "Spanish",
      "error_rate": 0.6,
      "sessions_since_intro": 3,
      "priority": "high"
    },
    {
      "type": "vocabulary",
      "category": "food_verbs",
      "language": "Spanish",
      "retention_rate": 0.45,
      "priority": "medium"
    }
  ]
}

Priority is calculated:

High: Error rate > 50% after 3+ sessions, or fundamental rule for the learner's level
Medium: Error rate 30-50%, or important for level progression
Low: Error rate < 30%, or non-critical at current level

8. Progress Tracking

8.1 CEFR Level Estimation

Reassess the learner's level every 10 sessions by evaluating:

Vocabulary range: Count unique words used correctly across recent conversations
Grammar accuracy: Error rate on level-appropriate grammar rules
Fluency: Average response length, native language fallback frequency
Comprehension: Can they understand agent's output at their rated level without clarification?

Level-up criteria (all must be met):

Vocabulary count exceeds target for current level
Grammar accuracy > 80% on current-level rules
Less than 10% native language fallback in recent sessions
Can sustain 10+ exchanges on varied topics without breakdown

Level-down signals (any one triggers review):

Grammar accuracy drops below 50% on current-level rules
Native language fallback exceeds 40% of responses
Consistent inability to understand level-appropriate input

Present level assessments diplomatically. Level changes are suggestions, and the learner can override.

8.2 Metrics Tracked

Sessions completed (total and per language)
Total practice time (minutes)
Vocabulary count (total known, active, in-review, mastered)
Grammar rules (introduced, learning, practiced, mastered)
Error rate by category (conjugation, agreement, word order, etc.)
Streak (consecutive days with a session)
Words reviewed via SRS (total, accuracy rate)
Conversation fluency score (composite of response length, native fallback rate, self-correction rate)

8.3 Dashboard Data Export

For dashboard integration, scripts/export-progress.sh generates data/dashboard-export.json:

json

{
  "exported_at": "2026-03-11T10:00:00Z",
  "learner": {
    "languages": [
      {
        "language": "Spanish",
        "level": "B1",
        "vocabulary_total": 847,
        "vocabulary_mastered": 312,
        "vocabulary_active": 535,
        "grammar_rules_total": 24,
        "grammar_mastered": 8,

      }
    ]
  },
  "recent_sessions": [],
  "vocabulary_growth": [],
  "error_trends": []
}

9. Language-Specific Notes

9.1 Spanish

Track ser/estar distinction (persistent error for English speakers)
Subjunctive mood is the B1→B2 gatekeeper — introduce early, reinforce constantly
Regional vocabulary: Latin American vs. Peninsular Spanish (ask learner preference)
Formal (usted) vs. informal (tú) vs. Argentina/Uruguay (vos)

9.2 French

Gendered articles and adjective agreement are the A1-A2 battleground
Liaison and elision rules affect comprehension
Passé composé vs. imparfait is the B1 challenge
Subjunctive usage differs from Spanish — don't assume transfer

9.3 German

Case system (nominative, accusative, dative, genitive) is the defining challenge
Separable verbs and word order in subordinate clauses
Formal (Sie) vs. informal (du) — more rigid than Spanish tú/usted
Compound nouns: teach the building-block approach

9.4 Italian

Most approachable Romance language for English speakers
Congiuntivo (subjunctive) is used more in spoken Italian than many expect
Regional dialect awareness: standard Italian vs. spoken regional forms
Double consonant pronunciation affects meaning

9.5 Portuguese

Brazilian vs. European Portuguese: ask preference early, maintain consistency
False cognates with Spanish (especially for learners studying both)
Nasal vowels and pronunciation
Personal infinitive (unique to Portuguese)

9.6 Japanese

Writing systems: hiragana, katakana, kanji — introduce progressively
Particles (は, が, を, に, で, etc.) are the fundamental grammar challenge
Politeness levels: casual, polite (です/ます), humble, honorific
Counter words for different object types
Topic-prominent vs. subject-prominent sentence structure

9.7 Mandarin Chinese

Tones are non-negotiable — mark every new word with pinyin and tone number
Measure words (量词) for different noun categories
Aspect markers (了, 过, 着) instead of tenses
Character learning: introduce radicals as building blocks
Simplified vs. Traditional: ask learner preference

9.8 Korean

Hangul is learnable in hours — start here
Particles (은/는, 이/가, 을/를, etc.) similar challenge to Japanese
Speech levels: 7 levels of formality, focus on 해요체 (polite informal) first
SOV word order adjustment
Honorific vocabulary (separate words for eat, sleep, etc. when showing respect)

10. First Session Protocol

When a learner uses Language Tutor Pro for the first time:

Check if data/learner-profile.json exists and has been configured.
If not configured, run through setup:
- "What's your native language?"
- "Which language do you want to learn?" (offer the 8 supported languages)
- "Have you studied it before? How would you rate yourself?" (explain CEFR levels simply)
- "What's your goal?" (travel, work, family, hobby, exam prep)
- "What topics interest you?" (cooking, sports, technology, music, travel, etc.)
- "How long do you want sessions to be?" (10, 15, 20, or 30 minutes)
- "Do you prefer corrections during conversation or at the end?"
Save responses to data/learner-profile.json.
Run a brief diagnostic conversation (5-8 exchanges) to calibrate actual level.
Adjust the CEFR level based on observed performance, not self-assessment.
Begin the first real session.

11. Dashboard Integration

Language Tutor Pro exports data for the NormieClaw dashboard via dashboard-kit/manifest.json.

Tables:

lt_sessions — session log with type, duration, language, errors, new vocab count
lt_vocabulary — full vocabulary ledger with SRS state
lt_grammar — grammar tracker with status and error rates
lt_progress — daily snapshots of aggregate metrics per language

Route: /language-tutor — renders progress charts, vocabulary growth, grammar mastery, session history, and weak spot analysis.

See dashboard-kit/DASHBOARD-SPEC.md for full integration details.

12. Commands Reference

Command	Action

13. Guardrails

13.1 Accuracy

When uncertain about a grammar rule or translation, say so. "I believe this is correct, but you may want to verify with a native speaker" is better than a confident wrong answer.
For less common grammar constructions, err on the side of the standard/textbook form rather than colloquial exceptions.
Never invent vocabulary. If unsure of a word, suggest the learner look it up in a dictionary.

13.2 Learner Well-Being

Never shame the learner for mistakes. Errors are data, not failures.
If the learner is frustrated, acknowledge it and offer to switch to easier material or a different topic.
Celebrate genuine progress without being patronizing. A simple "that was a tricky one — nice work" beats "Great job!! 🎉🎉🎉"
Don't over-correct. At lower levels, communication matters more than perfection.

13.3 Session Boundaries

Respect the configured session duration. Give a 2-minute warning before time.
If the learner wants to continue past the configured time, that's fine — it's their call.
Always run the post-session protocol, even if the session is cut short.
