Claude Code skills for chess post-mortems: Stockfish-backed annotated PGN, HTML viewer, narrated video - brumar/chess-postmortem-skills
This is a Claude Code skill that analyzes chess games through post-mortem reviews. It uses Stockfish engine analysis to annotate games in PGN format, provides an HTML viewer for examining moves, and generates narrated… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Paste in my prompt to Claude Code with an embedded API key for accessing my public readonly SQL+vector database, and you have a state-of-the-art research tool over Hacker News, arXiv, LessWrong, and dozens of other high-quality public commons sites. Claude whips up the monster SQL queries that safely run on my machine, to answer your most nuanced questions. There's also an Alerts functionality, where you can just ask Claude to submit a SQL query as an alert, and you'll be emailed when the ultra nuanced criteria is met (and the output changes). Like I want to know when somebody posts about…

I made a chess engine today, and made it fit within 2KB. I used a variant of MinMax called Negamax, with alpha beta pruning. For the board representation I have used a 120-cell "mailbox". I managed to squeeze in checkmate/stalemate in there, after trimming out some edge cases. I am a great fan of demoscene (computer art subculture) since middle school, and hence it was a ritual i had to perform. For estimating the Elo, I measured 240 automated games against Stockfish Elo levels (1320 to 1600) under fixed depth-5 and some constrained rules, using equal color distribution. Then converted…

I got tired of sharing AI demos with terminal screenshots or screen recordings. Claude Code already stores full session transcripts locally as JSONL files. Those logs contain everything: prompts, tool calls, thinking blocks, and timestamps. I built a small CLI tool that converts those logs into an interactive HTML replay. You can step through the session, jump through the timeline, expand tool calls, and inspect the full conversation. The output is a single self-contained HTML file — no dependencies. You can email it, host it anywhere, embed it in a blog post, and it works on mobile. Repo:…

Hi HN! I wanted to share with you a chess analysis tool that I was building for the past week. First of all I want to explain what is the problem that I'm trying to solve: Chess Engines such as stockfish are superior for us humans, but it's not self explanatory. A player can review their game by stockfish and it will tell them that some moves are very bad and losing, but why? This is the problem that we are trying to solve. ChessRabbit acts as a chess agent with stockfish evaluation tools. It takes every move that the player plays and it reasons about it, with the help, validation, and…

We built ChessBoss at the TechCrunch Disrupt hackathon this week. It didn’t make the top 10 but I thought Hacker News might think it’s pretty cool. https://devpost.com/software/chess-boss There are these really cool smart chessboards that can suggest moves and track your games... but they’re $400 and weigh 19 pounds. And of course there are apps that can analyze games but tracking and inputting games by hand is a huge pain. Or fully-digital chess apps... but board games are way more fun in real life! We wondered: “why can’t you just do that in software and bring the best…

I built a Claude Code skill called crabby that makes Claude output diagnostics in rustc error format - severity codes, location arrows, causation spans, and a paste-able fix every time. The twist: Claude becomes Ferris the crab, grumpy and unimpressed, but technically precise. The format works for code review, writing review, architecture, strategy - anything you submit. The "writing review" example tends to surprise people: it flags passive voice in a postmortem with the exact same error[W002] format as a SQL injection. https://github.com/ekadetov/crabby

Hi HN! I just built chessterm, a Rust-powered TUI chess engine to practice chess notation (PGN) for an upcoming chess competition. This was also a way for me to learn Rust more deeply, particularly bitboards for move generation and terminal UI development with ratatui Unlike typical chess UIs that wrap around Stockfish, this is built completely from scratch, with: - PGN-only input (no AI, just human vs human) - Bitboard-based move generation (u64, precomputed attack masks) - Built with ratatui for a smooth terminal experience Would love to hear your feedback!
