PDFx: bundles multiple PDFs into one valid file any viewer can read

Claude Fable 5 earns its reputation through how it works: explicit multi-stage planning, delegating to sub-agents, and verifying its own output before it trusts it. fable-mode bottles that behavior as a skill. Drop it into Claude Code and it activates that same disciplined loop, planning out the stages, splitting work to sub-agents, and self-checking the results, on whatever model you're running. #github #opensource

AI agents default to generating code. Ponytail makes your agent ask whether it should. Before writing anything, the skill forces it to reason like the laziest senior developer in the room — the one who knows the best code is the code you never wrote. Can this be done by deleting something? Reusing what exists? Not building it at all? Less code, less surface area, fewer bugs. The senior-engineer instinct, bottled into a skill. #github #opensource

Junction: a VS Code sidebar that runs your local coding agent inside the editor

Collaborating with AI agents on team documentation usually means copy-pasting markdown back and forth from Notion or Obsidian. OpenKnowledge is an open-source, AI-first alternative that lets you write side-by-side with your agents. it features a lossless bidirectional markdown sync. It connects directly to Claude or Cursor via MCP, giving your models live access to your files. #github #opensource
