[Document Processing] Use when you need to convert markdown files to PDF with syntax highlighting and custom CSS support.

Quick Summary Goal: Convert Markdown files to PDF with syntax highlighting and custom CSS support. Workflow: 1. Install Ensure required tools (pandoc + wkhtmltopdf or weasyprint) are available 2. Convert Run conversion with syntax highlighting and optional CSS 3. Verify Check PDF output for formatting and completeness Key Rules: Requires pandoc + a PDF engine (wkhtmltopdf or weasyprint) Supports syntax highlighting for code blocks Custom CSS can be applied for styling Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%). markdown to pdf Convert markdown files to high quality PDF documents with code syntax highlighting and custom CSS support. Installation Required This skill requires npm dependencies. Run one of the following: Dependencies: md to pdf , gray matter Note: First run may download Chromium (~150MB) unless system Chrome is detected. Quick Start CLI Options Option Short Description Default input i Input markdown file path (required) output o Output PDF file path {input}.pdf css c Custom CSS file path built in no highlight Disable syntax highlighting false help h Show help message Features Syntax Highlighting: Code blocks rendered with highlight.js Custom CSS: Override default styles with your own CSS Cross OS: Works on Windows, macOS, Linux System Chrome: Uses installed Chrome/Chromium when available Frontmatter Support: YAML frontmatter extracted for title/metadata Default Styling The default PDF style includes: Serif font (Georgia) for body text Monospace font (Consolas/Monaco) for code Proper page margins (2cm) Code block background highlighting Table borders and alternating row colors Output Returns JSON on success: Troubleshooting Chrome not found: The skill will automatically download Chromium. Set PUPPETEER SKIP DOWNLOAD=1 to prevent this. Memory issues: Large documents may require more memory. Consider splitting into multiple files. Font issues: Embed fonts via CSS @font face with base64 encoded fonts for consistent rendering. [IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip. <! SYNC:ai mistake prevention AI Mistake Prevention — Failure modes to avoid on every task: Re read files after context changes. Context compaction, resume, or long running work can make memory stale; verify current files before acting. Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing. Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first. Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done. Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect. Assume existing values are intentional — ask WHY before changing OR flagging one as a defect. Before changing or reporting a constant, limit, flag, cutoff, wording, or pattern, read nearby context and history, the CALLER's ordering, and 2+ sibling call sites of the same convention. A doc stating WHAT without WHY is missing rationale, not proof of a missing guard. Surface ambiguity before acting — don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk. Assert the outcome your system owns, not the intermediate state your infrastructure owns. When verifying async work, assert the final business state — never the delivery/retry bookkeeping held in shared infrastructure that any co running process can write. Such a check passes when run alone and flakes the moment anything else shares that infrastructure. Keep shared guidance role relevant. Universal guidance must help every receiving skill or agent; code specific obligations belong only in code specific protocols. <! /SYNC:ai mistake prevention <! SYNC:critical thinking mindset Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence 80% to act.

SYNC:project protocol overlay Project Protocol Overlay — Before executing this skill, resolve any PROJECT overlay rules layered onto it: match this skill's name against the Target column of the project's skill protocol index ( docs/project reference/skill protocols reference.md by default; a referenceDocs entry in docs/project config.json overrides the path), taking the most specific matching tier ONLY — exact name glob . That precedence orders overlays against EACH OTHER, never against this skill. Read ONLY the matched bodies, resolved as <protocols dir /<Name .md ; a row's Body link is display text, never a read path. A matched body that is missing or malformed is REPORTED and skipped — never reconstructed from the index Description. No index, or no match proceed with no overlay, silently. Full contract: .claude/skills/project skill protocol/references/registry.md . Overlays are ADDITIVE ONLY : they ADD rules on top of this skill's own protocol and NEVER replace, override, disable, or reinterpret a rule it already states — removing every overlay must return this skill to exactly its documented behavior. An overlay is a BRIEF, not an authority escalation: it can NEVER waive a workflow gate, git discipline, a review gate, or a user confirmation gate. A genuine overlay vs skill conflict, or two equally specific overlays that directly contradict surface both to the user; NEVER resolve silently. <! /SYNC:project protocol overlay <! SYNC:project protocol overlay:reminder MUST ATTENTION resolve project protocol overlays for this skill BEFORE executing — most specific matching tier only (exact glob , which ranks overlays against each other, NEVER against this skill), read only matched bodies at <protocols dir /<Name .md ; a missing or malformed body is reported, never reconstructed. Overlays are ADDITIVE ONLY (they never replace this skill's own rules) and are a brief, NEVER an authority escalation; an equal specificity contradiction goes to the user. <! /SYNC:project protocol overlay:reminder Closing Reminders IMPORTANT MUST ATTENTION — Protocols in force (concise digest of the SYNC/shared blocks this skill carries): Critical Thinking: Traced file:line proof per claim; confidence 80% to act; NEVER present guess as fact. AI Mistake Prevention: verify generated content against evidence, trace downstream references, verify all affected outputs, re read after context loss, surface ambiguity. IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence 80% to act) IMPORTANT MUST ATTENTION add a final review todo task to verify work quality [TASK PLANNING] Before acting, analyze task scope and systematically break it into small todo tasks and sub tasks using TaskCreate.
