## What it does

The plugin reads local transcripts from `~/.claude/projects` and builds an HTML page you can click through. You get token counts, how the cache behaved, which subagents and skills fired, and which prompts cost the most.

Handy when the API bill climbs and you can't tell why. Open the report, look at the expensive prompts, decide what to rewrite. Nothing leaves your machine — it all comes off disk.

It only runs in Claude. Other editors and CLIs won't work because the plugin depends on the `~/.claude/projects` layout. Installation goes through the `claude-plugins-official` marketplace.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text

- find the most expensive prompts
- check how well the cache performed
- spot which subagents and skills ran
- trace where the API spend is coming from

## Example prompts
- show me a report for the last session
- generate an HTML report of token usage
- which prompts cost the most in this session
