👋 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

# 1. Add marketplace
claude plugin marketplace add netil/oh-my-hi

# 2. Install plugin
claude plugin install oh-my-hi

Claude Code (via Plugin Marketplace)

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

Update

To update to the latest version, run the same install command:

# From the Command Line
$ claude plugin install oh-my-hi

# Claude Code (in-session)
/plugin install oh-my-hi@oh-my-hi-marketplace

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`	Regenerate data + web-ui without opening browser
`/omh --enable-auto`	Auto-rebuild on session end (registers Stop hook)
`/omh --disable-auto`	Disable auto-rebuild
`/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 rebuilds the dashboard data whenever a Claude Code session ends. Refresh the browser tab to see the latest data.

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

Parse — Reads your Claude Code config directory for skills, agents, plugins, hooks, memory, MCP servers, rules, principles, commands, teams, plans, and usage transcripts
Analyze — Extracts token usage, prompt stats, response latency, activity patterns from .jsonl transcripts
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
Build — Generates a single index.html with all data, CSS, JS, and locale inlined (works with file:// protocol, no server needed)
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).
