Language Coaching — Session Review

Analyze the user's messages in this session and provide detailed language coaching feedback.

Target Language

The target language is: $ARGUMENTS (default to en if empty or not specified).

Instructions

1. Review ALL user messages in this conversation
2. Reference the user's ACTUAL messages — quote specific phrases
3. Read ~/.claude/coaching/{language}-coaching.json using the Read tool
   • If the JSON file exists: use it as the source of truth for known patterns
   • If the JSON file does NOT exist but the .md file does: read the .md, perform a best-effort migration to create the JSON (see Migration Protocol below), then proceed
   • If neither file exists: proceed without memory context, note this in the review
4. For each language issue found in the session:
   • Check if a matching pattern exists in the JSON (search by id slug or similar native_form/target_correction)
   • If it matches an existing pattern: flag it prominently as recurring, increment times_corrected, update last_seen
   • If it is new: create a new pattern entry in the JSON
5. For known patterns that the user got RIGHT in this session:
   • Update last_correct_usage, increment times_correct_since_last_error
   • Progress SRS: interval_days = ceil(interval_days * ease_factor), next_review = today + interval_days
   • Mention this in Progress Notes as positive reinforcement 5b. For patterns with active SRS (next_review is not null):
   • Show the current SRS state in the review: interval, ease_factor, next_review
   • If next_review has passed, flag it as "overdue for review"
   • If reviewed and correct in this session, note the SRS progression
6. For vocabulary entries reviewed or taught in this session:
   • If the entry has a pronunciation field: display it in the Pronunciation section
   • If the entry has NO pronunciation field (pre-v1.3.0 legacy): generate one following the Pronunciation Guidelines from the language-coaching skill, update the JSON entry with the new field, and display it
7. Provide the review in the format below
8. After the review, write the updated JSON file
9. Regenerate the markdown file from the JSON (follow the Markdown Regeneration format from the language-coaching skill)
10. Check if a session entry for today already exists in sessions (from ambient coaching).
    • If yes: merge the review data into it. Append any newly discovered patterns to patterns_addressed, update notes to include "Session review performed"
    • If no: create a new entry with: date, project, patterns_addressed, new_patterns, patterns_correct, srs_reviews, vocabulary_taught, notes
11. Recalculate the stats object: total_sessions, total_corrections (sum of all pattern times_corrected), patterns_resolved, patterns_active, vocabulary_size, last_session

Migration Protocol (md-to-json)

When a .md memory file exists but no .json companion:

1. Read the markdown file
2. Parse each section and extract patterns:
   • Under "### Grammar", "### Spelling", etc.: extract each bullet as a pattern
   • Under "## False Friends Log": extract as false_friend type patterns
   • Under "## Vocabulary Acquired in Context": extract as vocabulary entries
   • Under "## Session History": extract as session entries
3. For each extracted pattern, create an entry following the Pattern Object Schema from the language-coaching skill:
   • Generate an id slug as {type}-{kebab-case-2-4-word-description} — NEVER use integer IDs
   • Set first_seen and last_seen to today (exact dates not recoverable from freeform markdown)
   • Set times_corrected to 1 (minimum, since it was recorded)
   • Set resolved to false
   • Include ALL required fields: native_form, target_correction, explanation, examples (array), times_correct_since_last_error: 0, last_correct_usage: null
   • Include SRS fields: next_review: null, interval_days: null, ease_factor: null
   • False friends go in the patterns array with type: "false_friend" — do NOT create a separate false_friends key
4. Create the JSON structure with version: 1
5. Write the JSON file
6. Regenerate the markdown from JSON (normalizes the format)
7. Proceed with the session review as normal

For All Languages (all)

Provide a combined review covering all active languages from the session. Separate each language into its own section.

Important

• Explain the WHY behind corrections, not just the fix
• Prioritize patterns over one-off typos
• Be encouraging about correct usage, not just corrective
• Use the user's native language for explanations when helpful
