What I cannot create, I do not understand — Richard Feynman.

Use Vibe-Coding to make “from-scratch” building faster, smoother, and more fun.

This repo preserves the spirit of build-your-own-x, and upgrades the workflow for the LLM era:

• Vibe-Coding = short iterative loops + lightweight prompt recipes + runnable scaffolds + tiny wins.
• LLMs in the loop: prompt recipes, debug diaries, and auto-checks live alongside the code.

A pragmatic build style:

1. Micro loops (15–25 min): set one tiny goal → build → run → jot what felt off (the “vibe”).
2. Prompt recipes: reusable 10–15 line prompts for planning, refactors, tests, and perf hints.
3. Scaffolds over specs: start from minimal templates; ship something runnable ASAP.
4. Reality checks: each step ends with an auto-runnable check (script/notebook/test).
5. Build diary: keep a vibes.md per project — 1–3 bullets/loop: intent → friction → next.

TL;DR: Less ceremony, more momentum. Learn a bit, run a bit, close the loop.

We’re actively collecting: Community showcases — repos/blog posts that used Vibe-Coding to complete a BYO-X project.

Open a PR or issue with:

• Link(s): repo and/or blog post
• Vibe artifacts: recipes/*.md (prompts), checks/* (auto-checks), scaffolds/* (minimal runnable)
• Build diary: vibes.md (3 bullets: intent → friction → next)
• Notes: compute used, dataset/source, license

Looking for real build diaries + prompts that wrap classic BYO-X topics.

1. Pick a topic → open blueprints/<topic>/README.md.
2. Copy the Prompt Recipes and follow the steps (each section stands alone).
3. Run the auto-check via checks/<topic>_smoke.* or a small notebook.
4. Log your loop in vibes.md so you can reproduce & share later.

• 🎯 Tiny intent: define one win.
• ✍️ Plan w/ recipe: paste system prompt (plan/refactor/test).
• 🛠️ Do the thing: code the minimum; prefer a scaffold.
• ✅ Auto-check: run checks/* and capture the output.
• 📝 Log vibe: append 1–3 bullets to vibes.md (intent → friction → next).

• Python: Mini-GPT: tokenizer → tiny Transformer → next-token sampling.

We love classic “from-scratch” tutorials and Vibe-wrapped upgrades.

For each PR, please include:

1. One minimal runnable example (script/notebook/app)
2. line prompt recipe (planning/refactor/test/perf) in recipes/
3. An auto-check in checks/ (smoke test or small eval)
4. short bullets from your vibes.md (intent → friction → next)

You can also “Vibe-wrap” any existing entry by adding a tail line under it:
