Build a small, coherent opening repertoire that fits your style and level — the few lines actually worth learning, plus the plans and traps behind them. Use when asked what chess opening should I learn, build me a repertoire, help with my openings, or what to play against [opening]. Produces a compact repertoire for White and Black keyed to your rating and style, the main ideas and typical plans (not just moves to memorize), the common traps to know from both sides, and what to study next — kept small enough to actually learn.
🗣 Say this to your agent
“What opening should I learn as a beginner who likes attacking?”“Build me a simple repertoire for White and Black.”“I keep losing against 1.e4 — what should I play?”“Give me a solid, low-theory opening system.”“Explain the plan behind the London System.”
What to give it
▸Rating / level — rough strength (beginner, club, intermediate) — sets how much theory is worth it
▸Style — attacking/tactical, solid/positional, or "just something reliable"
▸Colors & gaps — do you want White, Black, or both; anything you already play
▸Time — how much you'll realistically study
▸Trouble spots — openings you keep losing against
✅ The bar it holds itself to
Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.
✓Repertoire size matches the player's level (small for beginners)
✓Each opening comes with plans/ideas, not just move lists
✓Recommendations fit the stated style
✓Covers the replies they'll actually face
✓Includes common traps from both sides and a study order
⚠️ What it refuses to do
**A 20-move memorization dump** the player won't retain or understand.
**Style mismatch** — a sharp gambit for someone who wants solid.
**Only moves, no plans** — leaving them lost once theory ends.
**Obscure theory** irrelevant at their level.
**Too many openings** to ever learn properly.
