research-code-parsimony skillA
research-code-parsimony is agent-read markdown (skill) from uchicago-dsi/ai-sci-skills: Keep scoped implementation and review work from growing unnecessary code by identifying the real owner, real callers, and existing capability before adding surface. Use when writing, extending, or reviewing research code; for a dedicated cleanup pass over pre-existing debt, use a maintenance skill instead..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Research Code Parsimony ## Establish The Contract And The Owner First Before adding code, be able to state: - the behavior or scientific contract being requested, including what must stay reproducible; - the module, function, script, or config that already owns this behavior, and which callers actually exercise it; - whether a maintained dependency or a native language/library capability already provides it. Search before creating an owner. If none fits a genuinely new capability, create one clear owner rather than forcing unrelated behavior into an existing module. ## Reuse Before You Add - Extend an understood existing owner instead of introducing a parallel one. - Prefer a maintained dependency when it reduces ownership burden while meeting the scientific and operational contract. Check the standard library and present dependencies first. - Parsimony means less code to own — not fewest files, shortest diff, or clever one-liners. Readable, explicit code beats a compressed version. - Never satisfy the request by solving a smaller or easier scientific problem than the one asked for. ## Express Cohesive Families As Directories …

mdr add uchicago-dsi/ai-sci-skills/research-code-parsimony@git:20260922.86f870dmdr add uchicago-dsi/ai-sci-skills/research-code-parsimony@sha256:c3c8e7d82e944548Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
