Auto-archive Claude Code sessions to your Obsidian vault as a Karpathy-style LLM wiki. Passive, hook-driven, knowledge converges instead of accumulating.
3 files for Claude Code, Codex and OpenCode: settings, alluvium AGENTS.md, alluvium CLAUDE.md — 3,383 tokens loaded in every session.
AGENTS.md C 973 tok CLAUDE.md B 2,410 tok .claude/settings.json A — These files are Tespera/alluvium's own configuration — they tell Claude Code, Codex and OpenCode how to work on this repository, so they are not mods to install elsewhere. Copy one as a starting point and replace the parts that are about this project.
