Lexfolio

LexFolio — Legal Markdown-to-PDF Typesetting

LexFolio renders Markdown-formatted legal documents into professionally typeset PDF files. Built on ReportLab, it ships with a Noto Serif SC / Noto Sans SC / EB Garamond font stack, three brand color schemes, eight typography presets, and four document templates tuned for common legal deliverables.

Dual identity. LexFolio is both a WorkBuddy skill (this file) and an open-source Python project (Apache-2.0). The codebase is identical; this SKILL.md simply teaches WorkBuddy how to discover and invoke it. When distributed on GitHub, this file is harmless and can be kept.

Setup

Requires reportlab and pyyaml. Install before first use:

pip install reportlab pyyaml

Invocation

Option 1: Python API (recommended)

import sys
sys.path.insert(0, "{SKILL_DIR}")
from engine.api import md_to_pdf

# Basic call
md_to_pdf("input.md", "output.pdf")

# With template
md_to_pdf("input.md", template="opinion")

# With color scheme + font provider + preset
md_to_pdf("input.md", color_scheme="B", font_provider="noto", preset="executive")

Option 2: CLI

cd {SKILL_DIR}
python run.py input.md -t opinion               # legal opinion template
python run.py input.md -t memo                  # memo template
python run.py input.md -s C                     # color scheme C
python run.py input.md --preset executive       # executive preset
python run.py --demo -t opinion                 # built-in demo
python run.py --list-templates                  # list templates
python run.py --list-presets                    # list presets

Document templates

Resolution priority: CLI args > front matter > template defaults > theme.json baseline.

Brand color schemes

Typography presets

standard, executive, mobile, editorial, academic, deep, matrix (landscape), redline.

Markdown authoring

Front matter (YAML)

---
doc_type: opinion              # required: opinion / memo / review / analysis
title: Legal Opinion on XX     # cover title
firm_name_cn: XX Law Firm      # cover firm name (CN); overrides theme.json default
firm_name_en: XX LAW FIRM      # cover firm name (EN); opinion cover only
author: Jane Doe               # author / issuing attorney
date: June 15, 2026            # date
ref_no: LEGAL-OP-2026-015      # reference number (header right side)
addressee: XX Corp.            # addressee
confidential: true             # cover bottom confidential marker
cover_style: standard          # standard (white) or color (brand full-bleed)
color_scheme: B                # A / B / C
font_provider: noto            # noto (founder is kept as an alias of noto)
layout_preset: standard        # typography preset
---

Key constraints:

• doc_type is required; it determines the cover type and default typography.
• firm_name_cn / firm_name_en override the theme.json defaults. Set these when deploying to a new firm.
• cover_style: color enables a brand-color full-bleed cover (white text + accent line); default is standard (white background).
• The founder provider is kept as a backward-compatible alias of noto. The original Founder (FZ) commercial fonts were removed for licensing reasons; both providers now resolve to the same open-source Noto fonts (OFL). Configure custom fonts via theme.json paths.

Supported syntax

Limitations:

• Ordered (1.) and unordered (-) lists are not rendered with indentation; use "First / Second" or paragraph form instead.
• Footnotes render as inline paragraphs (not page-bottom); the superscript is visual only.

Signature page

The signature page must occupy its own page at the document end. Fixed structure:

<!-- pagebreak -->

## Signature Page

>right **Issuing firm:** XX Law Firm

>right **Issuing attorney:** Jane Doe

>right **Date:** June 15, 2026

*Disclaimer text.*

<!-- sigfooter -->

Key constraints:

• Leave one blank line before and after <!-- pagebreak -->.
• >right lines must not be separated by blank lines (blank lines parse as separate paragraphs).
• <!-- sigfooter --> must be the last non-empty line in the document.
• Use ## Signature Page (H2) for the heading, not H1.
