The winner of an Anthropic hackathon open sourced his entire Claude Code setup - and this is absolute f*cking gold 68 subagents, 286 skills, 94 commands, MIT license ECC swaps a lone Claude Code assistant for a whole engineering department a blueprint comes before any build, a failing test comes before any fix, and every change gets a second look from a context that never saw it written • who does what > planning - hand it a single sentence, get back a plan you sign off before a line of code > review - a fresh-context read of your diff, with its own reviewer for each language > build repair - a dedicated fixer per toolchain, PyTorch and CUDA included > security - an OWASP sweep, plus a scanner hunting injection holes in your agent config > architecture - catches design mistakes while they're still cheap, before they turn into migrations > domain work - database queries, ML pipelines, e2e tests, docs the security duo is the piece most people never set up an external OWASP audit costs four figures and a week of waiting this one wraps up on your branch by lunchtime • what the skills cover > testing - tdd-workflow moves you from red to green, eval-harness runs above it > language packs - Python, Go, Rust, C++, Django, Laravel, Spring Boot, Next.js > context - search-first checks the docs before writing, iterative-retrieval stops your whole repo flooding the window > shipping - Docker, CI/CD, health checks, rollbacks, migrations > beyond code - writing in your voice, market research, pitch decks fork it, trim it, and have your own version running by tomorrow begin with a single plan and a single rules pack turning on all 286 skills at once is the quickest way to make it worse whoever wires this in over a weekend spends the next quarter reviewing work instead of typing it
