Converts books and documents (PDF, EPUB, DOCX, HTML, Markdown, plain text, RTF, MOBI/AZW with Calibre) into structured agent skills, extracting frameworks, mental models, principles, techniques, and anti-patterns. Use when the user wants to study a document through GitHub Copilot CLI, Amp, Claude Code, Hermes Agent, OpenCode, or OpenClaw, apply an author's frameworks while working, or build a reusable knowledge base from a 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
<!--
Cross-agent notes (informational; ignored by host agents):
- Compatible skill roots: GitHub Copilot CLI (~/.copilot/skills, ~/.agents/skills,
.github/skills, .claude/skills, .agents/skills), Amp (.agents/skills,
~/.config/agents/skills, ~/.config/amp/skills), Claude Code (~/.claude/skills),
Hermes Agent ($HERMES_HOME/skills, .hermes/skills, .agents/skills),
OpenClaw (${OPENCLAW_STATE_DIR:-~/.openclaw}/skills, .agents/skills, skills/;
~/.agents/skills only with the default state).
OpenCode (~/.config/opencode/skills, ~/.claude/skills, .opencode/skills,
~/.agents/skills, .agents/skills).
- `allowed-tools` is intentionally omitted to stay agent-neutral: Copilot CLI uses
`shell`/MCP-server names, Claude uses `Bash`/`Read`/`Write`/`Glob`/`Grep`, Amp
adds `shell_command`. The skill needs shell (to run extract.py) and file
read/write — each host will prompt for those on first use.
- Argument hint: <path-to-document-folder-or-glob>... [skill-name-slug]

# Book-to-Skill Converter
Transform written knowledge into actionable agent skills by extracting structure — not producing summaries.
## Philosophy
…Read the whole file at its exact version.
How to install
mdr add virgiliojr94/book-to-skill/book-to-skill@sha256:6a3d7ce3d3689020The line at the top of this page pins the label git:20260929.ef51073, 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.
