Enzyme — OpenClaw plugin

Semantic search and pattern discovery for Obsidian vaults, exposed as an OpenClaw tool plugin.

Install

The plugin shells out to the enzyme CLI binary. Install that first:

curl -fsSL https://enzyme.garden/install.sh | bash
# or: brew install jshph/enzyme/enzyme-cli

Then install the plugin:

openclaw plugins install @jshph/enzyme-openclaw

For local development (--link mode), OpenClaw rejects symlinked deps that resolve outside the plugin root. Use a packed tarball of the sibling bridge package:

cd plugin/openclaw-bridge && npm pack --pack-destination /tmp
cd ../openclaw && rm -rf node_modules package-lock.json
npm install /tmp/enzyme-openclaw-bridge-*.tgz
openclaw plugins install $(pwd) --link

Configure your vault in ~/.openclaw/openclaw.json:

{
  plugins: {
    entries: {
      enzyme: {
        enabled: true,
        config: {
          vaultPath: "/Users/you/obsidian",
          autoRecall: true,
          autoRefresh: false
        },
        hooks: {
          // Required only when autoRefresh is enabled.
          allowConversationAccess: true
        }
      }
    }
  }
}

Tools

| Tool | What it does | |---|---| | enzyme_petri | Working memory: top entities + catalyst phrases. Run on first message. | | enzyme_catalyze | Semantic search by concept. Compose queries from petri catalysts. | | enzyme_status | Vault index stats. |

Hooks

• before_prompt_build — when autoRecall: true (default), enzyme petri --query <user msg> runs before each turn and prepends the result as system context.
• agent_end — when autoRefresh: true, runs enzyme refresh --quiet after each turn.

Caveats

• Auto-recall adds ~50–200ms per turn (8ms petri + spawn overhead).
• autoRefresh requires hooks.allowConversationAccess: true.
• This plugin does not claim the kind: "memory" slot, so it composes with memory-core and other memory plugins.
