Build a kit, a repo somebody lives inside for weeks while an agent walks them through a process they have never done and will not do again for years. Use when the user faces a long multi-session process with a deadline and an evaluator (applications, appeals, accommodations, estate admin, a job search, a fundraise, a thesis), when they ask for help with something bureaucratic they have never done, when they want to hand a process to a friend, or when they say "make a kit". Also use to decide…
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
# Kit builder A **skill** is one file that loads when relevant, fires once, and forgets. That is the right shape for most things and it is what you should build by default. A **kit** is a repo somebody lives inside for weeks. It carries state between sessions, drives the conversation instead of waiting for a prompt, and does arithmetic in real scripts because the model gets numbers wrong. It is the right shape when somebody has to be walked through something over weeks, under a deadline, where a wrong fact is expensive and they have no instincts to fall back on. Almost nobody in the ecosystem ships kits. There are thousands of skills. That gap is the opportunity, and it is also the trap: the temptation is to build a kit for everything, and a kit built around an afternoon's work is just ceremony around a prompt. ## First, run the test. Out loud, in one line each. Seven properties. **Five or more is kit-shaped. Four or fewer stays a skill.** 1. **Spans sessions.** Days or weeks. State survives a closed laptop. 2. **The bottleneck is extraction, not generation.** They have the material and cannot get it out. Nobody ever asked them the right question. …

How to install
mdr add calebnewtonusc/chewbacca/kit-builder@sha256:447d522656109e9fThe line at the top of this page pins the label git:20260904.ee0eb1b, 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.
