Discover md2pdf on GitHub
md2pdf converts Markdown files into PDFs locally, using an already-installed browser as the rendering engine instead of a TeX or LaTeX toolchain. It preserves rich Markdown formatting such as headings, tables, task lists, footnotes, and code blocks, and embeds local images and Mermaid diagrams while keeping HTTPS links clickable. Batch conversion across files or entire directories, with interactive and non-interactive modes and overwrite protection, makes it a lightweight option for developers and technical writers who need clean PDFs without a heavy dependency chain.
Discover agents-sync on GitHub
agents_sync is a cross-platform background daemon that keeps user-level custom agents and skills bidirectionally synchronised across Claude Code, Codex, Antigravity, and OpenCode. It allows engineering teams to construct their AI workflows and custom skills once, then execute them seamlessly from every developer tool installed in their local environments.
Discover scan-supply-chain on GitHub
scan-supply-chain acts as a security validation filter that detects indicators of compromise from PyPI and npm supply chain attacks before dependency compilation. Using extensible TOML threat profiles and blast radius mapping, it scans third-party manifests to alert engineers of rogue lifecycle scripts or unauthorized network sockets.
