This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
minimal-code-discipline from yeachan-heo/oh-my-claudecode is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

YAGNI-ladder coding discipline for writing changes — existence-first, reuse before writing, dependency ladder, shortest correct diff, with non-negotiables that must never be minimized away.
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
# Minimal Code Discipline Use this skill to apply a minimal-code (YAGNI-ladder) discipline while planning and writing code changes. It keeps diffs small and obviously correct without sacrificing the checks that keep users safe. This skill complements `ai-slop-cleaner`: that skill cleans slop after it lands; this one keeps it from being written. ## When to Use Use this skill when: - the user asks for a minimal, lean, YAGNI, or smallest-possible-diff implementation - a plan or in-flight change is growing beyond the stated request - writing new code where scope creep, reinvented helpers, or speculative generality are likely - reviewing a proposed diff for size before implementation ## When Not to Use Do not use this skill when: - the user explicitly asks for a broad, feature-rich, or future-proofed build (their explicit scope wins) - the task is exploratory scaffolding the user has marked as throwaway - minimization pressure would touch protected behavior (see Non-Negotiables) ## The Discipline **Existence first.** Ask whether the change needs to exist at all; skip work that serves only a speculative future need. …

How to install
mdr add yeachan-heo/oh-my-claudecode/minimal-code-discipline@sha256:4e013df3913cf512The line at the top of this page pins the label git:20260828.9d74f85, 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.
