Use when the user names one book, course, paper, or source document and asks to distill it into a reusable skill. Not for a folder of sources: use map-corpus.

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

# Book to skill

## Contract

| Field | Bound contract |
|---|---|
| Trigger | The user names one book, course, paper, or comparable single source document and asks to distill it into a reusable skill. |
| Authority | Reversible local: writes only the chosen target skill directory (SKILL.md and optional references/); rollback is deleting that directory. No remote mutation. No source file is mutated or copied wholesale. |
| Side effect | Creates files under the chosen target directory only; never copies the source document into the skill. |
| Done | A SKILL.md that parses as YAML, carries an attribution line, passes four validation checks, and routes correctly on at least two positive and two negative probe prompts. |

## Inputs

- The named source document, accessible as a file the agent can open. A document the agent cannot open stops the run.
- Optional: a write target directory, defaulting to `.claude/skills/<name>/`.
- A folder of multiple sources is out of scope; that belongs to corpus mapping, not this skill.

## Procedure
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add outlinedriven/outline-driven-development/book-to-skill@sha256:970ff829e9745c29

The line at the top of this page pins the label git:20260912.5c5b759, 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.
