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
# CLAUDE.md Choose the entry point from the user's task: - **Solve or resume a contest problem:** read [.agents/skills/cumcm-workflow/SKILL.md](.agents/skills/cumcm-workflow/SKILL.md) and follow it. The engineering instructions below do not apply to solving the contest problem. Resolve this link from the directory containing this file, not the contest workspace. - **Edit this workflow repository:** follow the engineering instructions below. Do not start a contest run unless requested. The Claude Code Skill at `.claude/skills/cumcm-workflow/SKILL.md` routes to the same canonical workflow. ## Layout `.agents/skills/cumcm-workflow/` is the single canonical tree: `SKILL.md`, `references/`, `schemas/`, `scripts/`, `assets/`. `.claude/skills/cumcm-workflow/SKILL.md` is a thin router into it and deliberately restates no rules — if you add a rule, it goes in the canonical tree only. ## Invariants to preserve when editing - **Machine facts are recorded, never hand-written.** If a change would make an agent type a SHA-256, an exit code, a page count or a result value into a contract, the change is wrong; extend a recorder instead. …

How to install
mdr add lucasuiii/modeling-workbench/CLAUDE.md@sha256:b99f8674dfb34ca4The line at the top of this page pins the label git:20260923.f8463ed, 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.
