Write a new skill, or fix one that is not being obeyed. Use when the user asks for a new skill, says a skill is being ignored or does the wrong thing, wants to turn a repeated task into something reusable, or asks to install a skill someone else wrote. Also use before writing any SKILL.md, because the authoring order matters more than the file.
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
# skill-forge Most skills fail the same way: somebody wrote the file before they had run the task. The file then encodes a guess, and the guess is obeyed. ## The order is the whole method 1. **Name the pain, then the problem, then the prompt.** If you cannot say what specifically goes wrong today, you are building for a problem nobody has. Stop here more often than feels comfortable. 2. **Run it by hand as a plain prompt.** Not once. Until the output is right and you know why it is right. 3. **Write the playbook.** Five parts, all of them: the rules, the steps, the standards for good output, worked examples, and the never-dos. This is prose, not a file format. 4. **Only now write `SKILL.md`**, from the playbook. 5. **Test it against the cases that broke in step 2.** Skipping from 1 to 4 is the failure this skill exists to prevent. ## Rules for the file itself **One task per skill.** The test: would you ever run this task on its own? If no, it is a step, not a skill. Skills that do five things or chain several events do not get obeyed. Chain narrow skills instead. **Open with one sentence saying what this is**, above all the detail. Detail …

How to install
mdr add calebnewtonusc/chewbacca/skill-forge@sha256:d3c62dba521b427bThe line at the top of this page pins the label git:20260921.3f3d9a0, 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.
