fluent

Atomically update all 6 Fluent learner databases (learner-profile, progress, mistakes, mastery, spaced-repetition, session-log) at session end by calling .claude/hooks/update-db.py with a single JSON payload. Use at the end of every practice session — fluent-writing, fluent-vocab, fluent-speaking, fluent-reading, fluent-review, fluent-learn — to persist the session's errors, review results, new vocabulary, and session metadata.

Canonical feedback template for every learner answer in the Fluent system — celebrate correct parts, correct mistakes with category and brief explanation, show the full correct version, score out of 10, and classify severity (🔴 critical / 🟡 moderate / 🟢 minor). Use in every practice session (fluent-writing, fluent-vocab, fluent-speaking, fluent-reading, fluent-review) immediately after the learner submits an answer.

Main adaptive language-learning session that mixes skills (writing, speaking, vocabulary, reading) and exercise types based on the learner's current level, weak patterns, and due reviews. Triggered only when the learner types /fluent-learn. Greets the learner, shows today's plan, asks what to practice, runs interleaved exercises one at a time, and updates all databases at the end.

Show the learner's language learning progress, statistics, mastery levels, streak, and achievements. Use when the learner asks "how am I doing", "show my progress", "stats", "dashboard", "what's my streak", "how many words have I learned", or invokes /fluent-progress. Read-only — safe to auto-invoke.

Run an interactive reading comprehension session with a short target-language text followed by main-idea, detail, vocabulary-in-context, inference, and true/false questions. Triggered only when the learner types /fluent-reading. Presents the text, waits for the learner to read, then asks questions one at a time with immediate feedback, and optionally adds new vocabulary to the spaced-repetition queue.

Run today's spaced-repetition review queue — items scheduled by SM-2 that need reinforcement before the learner forgets them. Triggered only when the learner types /fluent-review. Pulls due items from spaced-repetition.review_queue.today, generates a targeted exercise for each, evaluates the response, updates SM-2 parameters, and reshelves items into the correct future queue.

Parse Fluent `/results/*.md` session files to extract error patterns, strengths, accuracy trends, and focus areas for the next session. Use when the tutor needs to analyze the learner's recent performance — planning the next lesson, recommending focus areas, or answering "what should I practice next?".

One-time interactive onboarding that creates the learner's personalized language-learning profile — name, target language, native language, current/target CEFR level, timeline, daily minutes, and learning goals. Triggered only when the learner types /fluent-setup. Also handles profile updates and resets for returning users. Must never auto-invoke because re-running can reset progress.

SM-2 spaced-repetition algorithm reference for the Fluent language learning system. Use whenever the tutor schedules the next review of a vocabulary item, grammar rule, or error pattern — i.e. after every answered review question. Defines the 0-5 quality scale, interval formula, easiness-factor update, and mastery-level transitions that keep the spaced-repetition database correct.

Run an interactive typed conversation session simulating spoken practice — free-flowing dialogue, role-plays, and opinion questions prioritizing communication over perfect grammar. Triggered only when the learner types /fluent-speaking. Asks questions one at a time in the target language, evaluates clarity and naturalness first and grammar second, and updates all databases at the end.

Run an interactive vocabulary drill session with flashcard-style prompts, spaced repetition, and per-answer feedback. Triggered only when the learner types /fluent-vocab. Reads spaced-repetition / mistakes / mastery DBs to pick words, presents one word at a time, scores each answer, and calls fluent-db-updater at the end.

Run an interactive writing practice session (emails, letters, forms, short texts) with systematic error analysis, category-tagged corrections, and detailed feedback. Triggered only when the learner types /fluent-writing. Selects a scenario matched to mastery, lets the learner compose, then analyzes grammar, register, vocabulary, structure, and spelling before updating all databases.
