- A Dataset With No DatabaseTo ship structured data to an AI agent, skip the fancy formats: bundle a CSV in a skill and tell the agent to load it into SQLite. A tour of the alternatives, and why KISS and YAGNI win.
- A Knowledgebase With No Embedding ModelKB Packer turns a folder of documents into a portable, embedding-free .skill knowledgebase an AI agent can install and query — built entirely in the browser, byte-identical to the CLI.
- A jj-Native Hub for Claude Code on the Webclaude-jjithub-and-spoke is a CCotw template that gives Claude a jj (Jujutsu) VCS layer over GitHub — sibling of the gh-flavored and Tangled-flavored hubs.
