Justify by correctness, never by convention. Use when a design, fix, API, macro, library surface, hook message, or naming decision is defended by 'it's what the codebase does', 'the established pattern', 'the canonical lane does it', 'more ergonomic', 'less churn', 'already wired', 'smallest fix', 'compatibility', 'legacy path', or 'out of scope to change'. Prevalence and transition size are not evidence. Re-derive from correctness, name the bug the alternative causes, and be confident in the…
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
# /pizza1 Justify by correctness, never by convention. ## The trigger You defended a design by pointing at what the codebase already does. That is not a correctness argument. Re-derive from first principles. ## The core If a codebase named every variable `pizza1`, `pizza2`, `pizza3`, that would not make those names good. So **"it's what the codebase uses" is never a reason a design is correct.** It is incidental. Prevalence is not evidence. Transition size is not evidence. ## Banned justifications Delete these from the next response. None of them is a reason: - "it's what the codebase already does" - "the established pattern" - "the canonical lane does it" - "consistent with the rest" - "it's more ergonomic" - "less churn" - "already wired" - "fewer changes" - "smallest fix" - "smallest structural change" - "minimal change" - "least disruptive" - "preserves compatibility" - "keeps the legacy path working" - "lets us migrate later" - "parallel path for now" - "out of scope to change" - "not worth touching now" ## How to handle each case …

How to install
mdr add checkpickerupper/skills/pizza1@sha256:d7d4666dece4ec35The line at the top of this page pins the label git:20261021.61c15fb, 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.
