Pointer to the upstream skill for behavioural guidelines that reduce common LLM coding mistakes, installed from upstream.
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
# Karpathy guidelines (pointer)
Coco does not ship this skill because the upstream has no licence file, so this file only points to the original.
## Install from upstream
Review the upstream repository before you run its installer; Coco does not vet or pin it.
The lines below are Claude Code slash commands, not shell commands.

Coco will not reproduce the upstream text. If you are the author and want this link removed or changed, see docs/personas/TAKEDOWN.md.
The line at the top of this page pins the label git:20261008.3d24d40, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
