Single-binary Go web application patterns: - Project structure (cmd/, internal/, web/dist/) - Single embed file pattern - SPA routing with fallback handler - Development mode patterns - Anti-patterns to avoid Framework-agnostic: no vite/esbuild references.
- Document sql.Scanner/driver.Valuer pattern for custom types - Add JSONB override configuration example - Add nullable types guidance (sql.Null[T] and legacy types) - Update PostgreSQL type mappings table to reference custom types This helps projects use sqlc effectively for JSONB columns, domain-specific types, and custom nullable types.
- download-markdown.cjs: Download URL, detect Markdown via extensions, Accept headers, and HTML link parsing - html-to-markdown-recursive.cjs: Convert HTML files to Markdown recursively - website-download-recursive.sh: wget-based recursive website download - Markdown detection: 8 strategies including URL variants, Accept headers, and HTML link parsing (edit/source buttons, .md links, raw repo URLs) - Dependencies: @mozilla/readability, turndown, jsdom - Supports content-type headers, content sniffing, and frontmatter generation
- New script to split large markdown files for context loading - View TOC with line numbers (--toc) - Split by headers with size limits - Create index file for navigation - Skip code blocks and YAML frontmatter when parsing - Handles oversized sections with warnings Enables progressive disclosure: grep for headers, read only needed sections.
Modern Node.js supports 'import' on CJS modules natively. - Renamed .cjs → .mjs - Converted require() to import statements - Updated SKILL.md examples

markdown-split.cjsto the download-markdown skill for splitting large markdown files into smaller reference files.Problem: Large markdown docs exceed context windows. Reading 100KB of documentation burns tokens.
Solution: Progressive disclosure — split by headers, read only what you need.
Features:
--toc— View TOC with line numbers before splitting--index— Create INDEX.md listing all splits--depth N— Header depth to split on (default: 2)--max-lines/--max-bytes— Size limits per file--flatten— Flat numbered filenamesWorkflow:
Creates files suitable for progressive disclosure: use
grep -n '^#' file.mdto find headers, then read specific sections.
