# 👋 oh-my-hi (Oh My Harness Insights)
![oh-my-hi dashboard](https://img.shields.io/badge/Claude_Code-Plugin-blue)

> **Oh, so that's what Claude's been doing!** — A visual dashboard for your Claude Code harness.

Parses your entire Claude Code configuration and usage data, stores results in a local SQLite database, and serves an interactive dashboard via a local HTTP server.

## What it shows

- **Harness overview** — skills, agents, plugins, hooks, memory, MCP servers, rules, principles, commands, teams, plans
- **Context budget** — estimated token distribution between visible and invisible contexts (startup, tools, user messages)
- **Token analytics** — usage by model, daily trends, cache efficiency, prompt statistics, response latency
- **Token Breakdown** — per-item token attribution by context type (skill / agent / MCP / built-in tool). Shows startup context cost estimate (CLAUDE.md, skill descriptions, principles, MCP tool listings) multiplied by session count, plus a Top 5 per type and an expandable drill-down by type
- **Cache TTL Impact** — detects cost waste from short cache TTL. Shows best/worst 7-day rolling efficiency, estimated waste cost, and a daily hit-rate trend chart with reference lines
- **Month-end cost projection** — trailing 7-day average extrapolated to month end, compared against your monthly budget
- **Skill & agent efficiency** — per-item call count, avg tokens/call, total cost, and category cost share. Sidebar marks the top 3 cost contributors with a 🔥 badge so optimization targets are obvious
- **Context Window Explorer** — replay any past session turn-by-turn to see exactly how the context window filled up
- **Activity heatmaps** — daily usage patterns across skills, agents, and commands
