Omh

oh-my-hi

> Oh, so that's what Claude's been doing!

Generates a full harness insights dashboard and opens it in the browser.

Usage

• /omh — Full build (parse data → build web-ui → start local HTTP server → open browser)
• /omh --data-only — Regenerate data files only (server continues serving updated files)
• /omh --enable-auto — Enable automatic rebuild on session end
• /omh --disable-auto — Disable automatic rebuild
• /omh --status — Check auto-refresh status
• /omh --update — Check and install latest version
• /omh --help — Show help

First Run Guide

If the console output after running the script shows auto-refresh not configured, ask the user:

> Would you like to enable automatic dashboard data refresh on session end? > - If enabled, data is automatically refreshed at every session end, so the dashboard always shows the latest data. > - If disabled, you need to manually run /omh --data-only or /omh to refresh data.

If the user chooses enable, run --enable-auto. If they choose disable, explain the manual refresh method.

Behavior

1. Parses harness files from the Claude Code config directory
2. Analyzes usage data (history.jsonl, transcript)
3. Generates data files (data-core.js, data-usage.js) and index.html
4. Starts a local HTTP server (port 3939+) and opens browser

Architecture

• Local HTTP server: scripts/serve.mjs serves output/ over HTTP (port 8282, auto-detects next available); re-uses running instance on subsequent /omh calls
• --data-only: Regenerates data files only; server continues serving the updated files on next browser refresh
• Auto-refresh: --enable-auto registers a Stop hook — rebuilds data on every session end
• Browser open: macOS open, Windows start, Linux xdg-open

Find and run the script (picks the latest version from cache, falls back to marketplaces):

PLUGINS_DIR="${CLAUDE_CONFIG_DIR:-$HOME/.claude}/plugins"
# Pick the highest semver version from cache (sort -V handles semantic versioning)
SCRIPT=$(find "$PLUGINS_DIR/cache" -name "generate-dashboard.mjs" -path "*/scripts/generate-dashboard.mjs" 2>/dev/null \
  | sort -V | tail -1)
# Fallback to marketplaces directory
if [ -z "$SCRIPT" ]; then
  SCRIPT=$(find "$PLUGINS_DIR/marketplaces" -name "generate-dashboard.mjs" -path "*/scripts/generate-dashboard.mjs" -print -quit 2>/dev/null)
fi
if [ -z "$SCRIPT" ]; then
  echo "oh-my-hi: ERROR — generate-dashboard.mjs not found. Try: /omh --update"
  exit 1
fi
# Ensure claude CLI is findable for --update (plugin context may have a stripped PATH)
