skill-forge is agent-read markdown (skill) from calebnewtonusc/chewbacca: 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..
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
# 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

Pin 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.
