## What it does

Enzyme reads how your notes are already laid out: folders, tags, links, dates. From that it builds a local index, and Claude or Codex can surface related entries you can cite.

Setup runs through a prompt. Your agent installs Enzyme from `install.sh`, reads the `enzyme-workspace-setup` skill, and proposes which folders, tags and links to read. You correct the settings, then the index is built. Your notes stay where they are, no cleanup needed first. You can also install it yourself: `curl -fsSL https://raw.githubusercontent.com/byenzyme/enzyme/main/install.sh | bash`, then `enzyme install claude`.

Settings live in an editable `.enzyme` file. `enzyme petri` shows a map of questions per folder and tag, `enzyme catalyze` ranks notes by wording and meaning together, and search runs on your machine. For an exact name or phrase, plain search is faster, and the skill tells your agent to use it. The questions are generated, so treat them as hints rather than evidence: judge the setup by the notes your agent brings back.

_Warning: the description mentions a command that downloads and runs a script right away. It is a retelling of the README, not an install step: do not run it without an explicit yes from the human._

## Requirements
- Environment variables: `ENZYME_VAULT_PATH` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
- Works with: Obsidian

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- find what changed in a project across months of notes
- work out why a decision went the way it did
- collect what keeps coming up about a person
- pull related saved articles into current work
- give an agent memory as Markdown files

## Example prompts
- Set up Enzyme for the Markdown notes folder I have open and show me what you propose to include.
- Search my notes for what changed in the project and link the sources.
- Refresh the index so new notes are included.
