| chess-engine | Use when tasks involve chess analysis, best-move finding, FEN/PGN parsing, or checkmate puzzles. Chess tasks require external engines -- reasoning alone cannot find optimal moves. | FEN string or chess position description |
Protocol Integration
DECISION LOOP Position
This skill applies at step 5 of the DECISION LOOP:
1. CLASSIFY -> complexity? backup needed? tools?
2. PROTECT -> cp file file.bak (for configs, DBs)
3. MEMORY -> query relevant context + past failures
4. AGENTS -> check overlaps (if multi-agent)
5. SKILLS -> @Skill:chess-engine.md for domain-specific guidance
6. WORK -> implement (ALWAYS use worktree for ANY file changes)
7. REVIEW -> self-review diff before testing
8. TEST -> completion gates pass
9. LEARN -> store outcome in memory

Chess Engine Integration
Detection
Keywords: "chess", "best move", "FEN", "PGN", "checkmate", "Stockfish"
Protocol
- Check for Stockfish:
which stockfish || apt-get install -y stockfish - Parse board state to FEN format
- Use Stockfish for analysis:
echo -e "position fen <FEN>\ngo depth 20\nquit" | stockfish - Extract best move from engine output (
bestmoveline)
Rules
- NEVER try to calculate chess moves through reasoning -- use the engine
- Use
python-chesslibrary for FEN validation and move legality checks - For multi-move analysis, use
go depth 20minimum - Parse UCI output format:
bestmove e2e4 ponder d7d5
