👋 oh-my-hi (Oh My Harness Insights)

Harness Insights — A visual dashboard for your Claude Code harness.

Parses your entire Claude Code configuration and usage data, then generates an interactive single-file HTML dashboard you can open locally.

What it shows

• Harness overview — skills, agents, plugins, hooks, memory, MCP servers, rules, principles, commands, teams, plans
• Token analytics — usage by model, daily trends, cache efficiency, prompt statistics, response latency
• Activity heatmaps — daily usage patterns across skills, agents, and commands
• Task categories — auto-classified token usage by work type (code editing, docs, planning, etc.)
• Multi-workspace — switch between global and per-project scopes

Installation

From the Command Line

claude plugin marketplace add netil/oh-my-hi
claude plugin install oh-my-hi

Claude Code (in-session)

/plugin marketplace add netil/oh-my-hi
/plugin install oh-my-hi@oh-my-hi

Usage

Run in Claude Code:

/omh

This will parse your harness data, build the dashboard, and open it in your browser.

Parameters

Command	Description
/omh	Full build — parse data, build web-ui, open in browser
/omh --data-only	Lightweight data collection (skip dashboard build)
/omh --enable-auto	Auto-rebuild on session end (registers Stop hook)
/omh --disable-auto	Disable auto-rebuild
/omh --update	Check and install latest version
/omh --status	Check auto-rebuild status
/omh <path>	Build with specific project paths only

Auto-refresh

Enable automatic data refresh so the dashboard stays up to date:

/omh --enable-auto

This registers a Stop hook that collects data whenever a Claude Code session ends. The dashboard data (data.js) is updated incrementally — just refresh the browser tab to see the latest data.

Update

/omh --update

Checks for new versions and updates the plugin. An update check also runs automatically once per day when using /omh.

Guide

See GUIDE.md for a detailed walkthrough of each dashboard section — overview, token analytics, cost estimation, structure view, category pages, and more.

How it works

1. Parse — Reads your Claude Code config directory for skills, agents, plugins, hooks, memory, MCP servers, rules, principles, commands, teams, plans, and usage transcripts
2. Analyze — Extracts token usage, prompt stats, response latency, activity patterns from .jsonl transcripts
3. Classify — Auto-categorizes token usage into work types (code editing, docs, planning, etc.) based on skill/agent descriptions. Saves to task-categories.json for user customization
4. Build — Generates index.html (shell with CSS/JS) + data.js (minified data). Data is separated from the shell so that only data needs updating on refresh
5. Open — On macOS, reuses an existing browser tab if found (AppleScript). On Windows/Linux, opens a new tab

i18n

• English: Built-in default
• Other languages: A template locale file is auto-generated on first build. Translate it and rebuild

Privacy

All data stays on your machine. oh-my-hi reads only local Claude Code config files and transcripts — nothing is sent to external servers. The generated dashboard is a standalone HTML file opened via file:// protocol, with no network requests. Your usage data, token statistics, and configuration details never leave your local environment.

Browser support

The dashboard opens as a local file:// HTML file. No web server required.

On macOS, subsequent builds will refresh the existing browser tab instead of opening a new one (Chrome and Safari supported).
