Chess Coach

This skill helps you improve your chess game by monitoring your Chess.com profile and offering advice tailored to your skill level.

Features

• - Profile Tracking: Connect your Chess.com username and track stats across formats (Blitz, Bullet, Rapid).
• Recent Game Analysis: Analyze your most recent games and identify coaching opportunities.
• Skill-Level Calibration: Automatically Adjusts advice based on your current rating.

Workflows

1. Setup

When a user mentions chess or improving their game for the first time:

1. 1. Ask for their Chess.com username.
2. Use scripts/chess_api.py <username> stats to fetch their rating and stats.
3. Store the username and their preferred formats (Blitz, Bullet, Rapid) in memory/chess_state.json.

2. Monitoring & Analysis

Periodically or upon request:

1. 1. Fetch recent games using scripts/chess_api.py <username> games.
2. Compare the game list against memory/chess_state.json to ensure no games are analyzed twice.
3. Daily Budget: Only analyze one game per 24-hour period unless specifically requested.
4. If new games exist, pick the most relevant one (e.g., a loss where the rating gap was small) and analyze it.
5. Observation Logging: Instead of just giving a one-off tip, log the core mistake or pattern (e.g., "Missed pin on d-file", "Weakened back rank") to memory/chess_observations.jsonl.
6. Consult references/skill_levels.md for coaching focus based on the user's current rating.
7. Provide 2-3 actionable points. Keep it punchy and encouraging.

3. Synthesis (The "Grand Lesson")

Once per week, or when memory/chess_observations.jsonl reaches 5+ entries:

1. 1. Review the logged observations to find recurring themes.
2. Identify the single "highest ROI" area for improvement (e.g., "You lose 40% of games due to early Queen excursions").
3. Present this as a dedicated "Coaching Review" session.

Example

"I see you've played 10 Blitz games since we last talked. In your game against 'Grandmaster123', you missed a simple fork on the f2 square! At your current rating (850), focusing on basic tactics like these will help you reach 1000 fast."
