README

pdf-material-builder

A Claude Code skill that builds teaching material and technical documentation as LaTeX PDFs, at any length, in one house style and one voice. A 1pp cheat sheet, a 2-6pp companion to a single lesson, a 40-70pp set of course notes, a design note: same page, same two faces, same twelve blocks, same author. The look is `references/house-style/style-spec.md`.

`SKILL.md` is the entry point. Everything below it is a level of detail you can stop at.

Install

Machine-wide, for every session on this box:

git clone --recurse-submodules https://github.com/ihsan-sa/pdf-material-builder ~/.claude/skills/pdf-material-builder

The skill carries [diagram-maker](https://github.com/ihsan-sa/diagram-maker) as a submodule in `diagram-maker/`, which is where its figures come from. `./install.sh`, run from any checkout of this repo, fast-forwards that clone to main and moves its diagram-maker to diagram-maker's latest main; on this box the landing runs it after every merge. It never makes the installed skill a symlink, and it leaves a missing or foreign directory alone. `scripts/build.sh` also moves diagram-maker to its latest main before it renders a document's figures, and quietly skips that offline.

Or vendored into one workspace, so the skill travels with the repo and every worktree of it:

git subtree add --prefix .claude/skills/pdf-material-builder \
  https://github.com/ihsan-sa/pdf-material-builder main --squash

Update a vendored copy with `git subtree pull` on the same prefix. Do not edit it in place: change this repo and pull. A subtree does not carry the diagram-maker submodule, so a vendored copy draws its figures with the TikZ kit unless diagram-maker is checked out into its `diagram-maker/`.

**What must be installed: lualatex, and texlive-luatex (luaotfload) alongside it.** The fonts (Source Serif 4, IBM Plex Mono) are vendored in `assets/fonts/`. Build any document with the skill's own script, from any repo:
