What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-29, confidence not recorded
A cross-platform AI agent skill that gives CLI coding agents like Claude Code, Codex, and Gemini CLI persistent long-term memory stored as plain markdown in an Obsidian vault. It provides ~45 natural-language commands for capturing, searching, and self-maintaining knowledge notes, including hybrid semantic search, self-rewriting pages, web research, and scheduled background agents.
Use cases
- give Claude Code persistent memory across sessions
- stop re-explaining projects and decisions to AI agents every session
- keep a self-maintaining second brain in Obsidian markdown
- search my vault semantically from the terminal
- have an agent maintain and reconcile my notes overnight
- capture ideas and log dev sessions to a knowledge vault
- share one knowledge base across multiple AI CLI agents
When to choose
- you use Obsidian and CLI AI agents and want durable, portable memory in plain markdown
- you want your knowledge base to update and reconcile itself rather than just accumulate notes
- you switch between multiple agent CLIs and want a single shared brain
When to avoid
- you don't use Obsidian or don't want your notes in a markdown vault
- you need a hosted or GUI-first memory solution rather than a CLI-agent skill
- you're uncomfortable with agents autonomously rewriting your notes
