Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| analyzeA | Analyze a chess position with the Stockfish engine and return the best move. Accepts a position as FEN or PGN (or omit it for the starting position). Returns the best move (in both UCI and human-readable SAN), the engine's evaluation, and whose turn it is. Optionally include the engine's predicted best line. Use this whenever you need the strongest move or an evaluation for a chess position. You do NOT need to set up the position and search separately — one call does both. |

Scored across 1 tool
Only one tool exists, so there is no possibility of confusion or overlap with other tools.
With a single tool, naming is trivially consistent and fits a clear verb-noun pattern (analyze_? but the tool name is just 'analyze', which is appropriate).
A single tool is borderline for a chess engine server; it bundles position setup and search, which works but limits flexibility (e.g., no separate depth control or multiple analysis modes).
The tool covers the main use case of analyzing a position with evaluation and best move. It accepts FEN/PGN, making it versatile, but lacks advanced options like depth parameter or multi-move output.
