Install the Wiki Dedup skill

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

npx skills add https://github.com/Ar9av/obsidian-wiki --skill wiki-dedup

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/wiki-dedup ~/.claude/skills/wiki-dedup

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.

What it costs your context

Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.

When	What loads	Cost
Every session	Name and description	44 tok
When the agent uses it	The SKILL.md instructions	3,946 tok
Only if opened	No bundled files	—

Until it is used, wiki-dedup costs about 31× 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
