Install the Copilot History Ingest skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/Ar9av/obsidian-wiki --skill copilot-history-ingest

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/Ar9av/obsidian-wiki.git /tmp/obsidian-wiki
mkdir -p ~/.claude/skills
cp -R /tmp/obsidian-wiki/.skills/copilot-history-ingest ~/.claude/skills/copilot-history-ingest

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

Until it is used, copilot-history-ingest costs about 30× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 40 skills from Ar9av/obsidian-wiki would load 1,925 tokens of descriptions. Skills vs MCP study
