karpathy-principles from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add athola/claude-night-market/karpathy-principles@git:20261023.bf6e922

Pre-implementation gate covering think-first, simplicity, surgical edits, and verifiable goals. Use when starting implementation to verify the approach.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

> The models make wrong assumptions on your behalf and
> just run along with them without checking. They don't
> manage their confusion, don't seek clarifications,
> don't surface inconsistencies, don't present
> tradeoffs, don't push back when they should.

## What This Is

A four-principle contract for reducing the most common
LLM coding pitfalls. Compact entry-point. Each
principle has a deeper-dive skill in night-market;
this skill is the index, not the encyclopedia.

Derivation: distilled by Forrest Chang
(forrestchang/andrej-karpathy-skills, MIT) from
Karpathy's observations. Full attribution in
`references/source-attribution.md`.

## When To Use

- Before starting any coding task larger than a typo
- During code review, to name the failure mode you see
- After writing a diff, to self-audit before claiming
  done
- When training a junior engineer to read agent diffs

## When NOT to Use

These principles bias toward caution over speed. For
cases listed in `modules/tradeoff-acknowledgment.md`,
use judgment: trivial fixes, exploratory spikes,
documentation-only edits, and time-boxed prototypes.

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/karpathy-principles@sha256:6b01aeb9c6798efa

The line at the top of this page pins the label git:20261023.bf6e922, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
