name: write-concept description: Use when creating or improving educational concept files - includes curriculum research for new concepts, always updates translations before validation

Write Concept

Process

1. Understand

• Clarify: country, subject, grade, concept scope
• Ask user if anything is unclear

2. Research (new concepts only)

• Skip if curriculum info provided (e.g., from bulk-generate-concepts)
• Otherwise: WebSearch "[country] [subject] curriculum [grade]"
• Find official curriculum documents
• Extract: concept scope, learning objectives, difficulty progression

3. Read rules

• docs/concept-rules.md
• content/schema.ts

4. Write/edit concept file

• Location: content/subjects/{subject}/official/{id}.md
• Follow concept-rules.md for all field requirements
• Always update: version (increment) and version_notes (describe changes)
• Prerequisites: Check content/subjects/{subject}/official/ for existing concept IDs

5. Update translations

• Update ALL files: packages/frontend/public/locales/*/subjects/{subject}.json
• Key: concepts.{concept-id} with name and description

6. Validate

bun run check:concepts {subject}/{concept-id}

Red Flags

• "I'll skip curriculum research" → You won't know what to put in fields
• "I'll add examples to help the AI" → CARDINAL RULE violation
• "Problem types look similar but different" → Not distinct enough
