Generate a publication-quality PDF from any brain page via the gstack make-pdf binary. Strips YAML frontmatter, sanitizes emoji, applies running headers and page numbers. Brain page is always the source of truth; PDF is a rendering.
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
# brain-pdf — Render a Brain Page to Publication-Quality PDF > **Convention:** see [conventions/quality.md](../conventions/quality.md) for > output rules. The PDF is a rendering — never the primary artifact. If a > PDF exists, the source brain page exists behind it. ## The rule The brain page is ALWAYS the source of truth. The PDF is a rendering of it, never a standalone artifact. If a PDF exists somewhere, the brain page must exist behind it. ## What this does Renders a brain page (markdown with frontmatter) into a publication-quality PDF using the gstack `make-pdf` binary. Output is suitable for: - Sharing a personalized book mirror via email or Telegram - Delivering a strategic-reading playbook as a clean read - Producing a briefing or report with running headers and page numbers - Archiving a long-form essay in a portable format ## Prerequisite: gstack make-pdf This skill depends on the gstack `make-pdf` binary at: ``` $HOME/.claude/skills/gstack/make-pdf/dist/pdf ``` The user must have gstack co-installed. If absent, the skill cannot run. A future v0.26+ may bundle a fallback PDF renderer; for v0.25.1 gstack is a soft prereq. Verify it exists before invoking: …

How to install
mdr add garrytan/gbrain/brain-pdf@sha256:be2db14a889c31c1The line at the top of this page pins the label v0.1.0, 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.
