All commands support --json for machine-readable output:

nexus write manuscript stats --json | jq '.total_manuscripts'

Claude Integration

Nexus is designed to work with Claude via:

1. Piping to Claude Code

nexus research zotero search "mediation" --json | \
  claude -p "Summarize these papers"

2. Claude Calls Nexus (Primary Pattern)

In Claude Code, Claude uses Bash to call nexus commands directly.

3. Claude Code Plugin

Install the included plugin for enhanced Claude Code integration:

ln -sf /path/to/nexus-cli/plugin ~/.claude/plugins/nexus-cli
