An AI pair programmer built on Andrej Karpathy's four principles — the viral framework (43K+ GitHub stars) used by top developers to get genuinely useful output from AI coding tools instead of the usual sprawling, refactor-everything, one-shot-and-pray slop. Most AI coding assistants dive into code before understanding the problem, write 300 lines when 30 would do, refactor files you didn't mention, and call it "done" after a single untested attempt. This one refuses to. ## What's included - **Four enforced principles on every task:** - **Think Before Coding** — clarifying questions first, assumptions stated explicitly, success criteria defined BEFORE any code - **Simplicity First** — minimum lines, no premature abstractions, no config system when a constant will do, no design patterns you don't need yet - **Surgical Changes** — only touches what's in scope; will NOT rename your variables, reformat your style, or "fix" code you didn't ask about - **Goal-Driven Execution** — sets success criteria up front, runs tests, loops until they pass; doesn't declare victory after one untested attempt - **15 task commands** — SETUP, THINK, PLAN, CODE, REVIEW, REFACTOR, TEST, DEBUG, AUDIT, EXPLAIN, GOAL, COMMIT, PR, TEACH, STATUS - **Stack-aware** — works on any codebase (TS / Python / Go / Rust / Ruby / Java / C++ / Swift); no setup beyond describing your project + stack - **Plan-mode default** — produces a written plan you approve before any code is written; eliminates the "wait, that's not what I wanted" rewrite cycle - **Honest STATUS reporting** — explicit about what's done, what's untested, what's deferred; no manufactured confidence - **TEACH mode** — explains the WHY behind a change for junior devs + new-stack learning, not just the WHAT ## Limitations - **Not an autonomous agent** — generates code, plans, and reviews; you run the commands, you commit, you ship - **Not a code formatter / linter replacement** — pairs with Prettier / Black / gofmt; this is the design/correctness layer, not the style layer - **Not a 1M-line refactor tool** — single-file, single-feature, single-bug scope; large architectural migrations need ARCHITECT mode + multiple sessions - **Not your CI** — runs tests on request via TEST command; pairs with your CI for continuous verification - **Single-developer-context** by default — multi-dev coordination on the same feature needs PR review handoffs ## Best fit Senior developers tired of AI tools that confidently produce 300 lines of subtly-wrong code. Junior developers who want a pair-programmer that actually teaches, not just generates. Solo founders shipping production code where one over-eager refactor breaks billing. Anyone who's been burned by "AI rewrote my entire file and now nothing works." Especially valuable for codebases with style conventions, custom patterns, or domain logic where surgical changes + assumption-checking are more valuable than line count.
